Editing History of Luigi

'''[[Luigi]]''' is the second of the titular protagonists of the ''Super Mario'' series, alongside his brother [[Mario]], and as such, he has appeared in several forms of media, including video games, comic books, and animation. He is either the star of games focused on him (like ''Luigi's Mansion'' and ''Mario is Missing!''), a captive awaiting to be rescued (''Super Princess Peach'' and ''The Super Mario Bros. Movie''), or is entirely absent in general (''Super Mario 64'' and ''Super Mario Sunshine'').

==History==
===''Mario Bros.'' (Game & Watch)===
[[File:MBG&WLuigiSprite.png|thumb|A sprite of Luigi from ''Mario Bros.'']]
Luigi first appeared in ''[[Mario Bros. (Game & Watch)|Mario Bros.]]'' for the [[Game & Watch]], where he loads cases of bottles in a bottling plant<ref>"We all know Mario who saved the beautiful girl from Donkey Kong. Now he's back with his brother Luigi, working in a bottling plant, loading cases on a conveyor belt. The conveyor carries the cases up for loading onto trucks." - ''Mario Bros.'' Game & Watch manual, page 4</ref> onto trucks with Mario. Luigi is placed on the left,<ref>"The left button moves Luigi up and down to carry cases to the next higher conveyor." -''Mario Bros.'' Game & Watch manual, page 8</ref> while Mario is on the right. Luigi is the one who loads the truck, as well. Other than position, Luigi is identical to Mario in this game. However, in the box art and ads, he is shown wearing green overalls.

Luigi next appears in ''[[Mario Bros. (game)|Mario Bros.]]'', where he is simply a palette swap of [[Mario]], having the same actions and abilities as Mario. This appearance is often incorrectly attributed as his first. Aside from his green and black color scheme, there are no other differences in physical appearance. In the game, Luigi and Mario are portrayed as plumbers, who are trying to rid the sewers where they are working from [[Shellcreeper]]s, [[Freezie|Slipice]]s, and many other monstrous creatures. In the remakes of this game, such as the one in ''[[Super Mario All-Stars]]'', Luigi's color scheme changes to his current color scheme, which is based on the game, though his attributes remain unchanged. Luigi was played by an unknown actor in a live-action commercial for the Atari 2600 version of ''Mario Bros.''<ref name="mbcommercial" /> The commercial portrays Luigi as a coward, though it is unknown if this had any influence on Luigi's current personality or not.

Luigi reprises his role as the second player in two Japan-only computer games, ''[[Mario Bros. Special]]'' and ''[[Punch Ball Mario Bros.]]'' Like the original arcade game, the brothers have to clear each phase of pests.

Luigi is absent from ''[[Mario Clash]]'' on the [[Virtual Boy]].

===Family BASIC===
The [[Family BASIC]] is a Japan-only accessory to the [[Family Computer]] that allows players to make their own programs. While Luigi is not included as one of the usable sprites, the manual gives instructions on how to create him by palette-swapping Mario.

===''Wrecking Crew'' series===
[[File:WC Luigi Sprite.png|frame|left]]
Luigi is once again the second player in ''[[VS. Wrecking Crew]]'' and its successor, ''[[Wrecking Crew]]''. Luigi's sprite is a palette swap of Mario's, having him dressed in bright red and having dark blue eyes and hair with a dark blue hammer, and paler skin than Mario's. Luigi has the same controls and role as Mario. However, in the former game's single-player mode, the computer-controlled Luigi will act as an opponent to Mario, reminiscent of [[Foreman Spike]] in the latter game.

In ''[[Wrecking Crew '98]]'', Luigi can be unlocked for multiplayer mode after beating single player mode.

===''Super Mario'' series===
====''Super Mario Bros.''====
[[File:SMB Super Luigi Sprite.png|frame]]
In ''[[Super Mario Bros.]]'', Luigi has the same jumping powers, same traction, and the same running speed as Mario. He is only playable in 2-player mode and is controlled by the second player only. Luigi's color scheme in this game shows him in a green shirt with white overalls and cap, along with having green hair and a green mustache, while the ''[[Super Mario All-Stars]]'' remake of the game show him in a blue shirt with green overalls and cap, along with having black hair and a black mustache. In ''[[Super Mario Bros. Deluxe]]'', he looks like Mario but with green overalls and cap.

====''Super Mario Bros.: The Lost Levels''====
Luigi also appears in the Japan-only sequel of ''Super Mario Bros.'', ''[[Super Mario Bros.: The Lost Levels]]'', known as ''Super Mario Bros. 2'' in Japan. For the first time, Luigi could now jump higher and further than Mario, though he has less traction, causing Luigi to slide slightly after moving. Instead of being strictly available only in 2-player mode, players could select him as their character in the single player adventure. His sprites from this game are reused from ''Super Mario Bros.''

====''Super Mario Bros. 2'' / ''Super Mario Advance''====
[[File:Luigi_SMB2.png|thumb|Luigi in ''Super Mario Bros. 2'']]
In the Western ''[[Super Mario Bros. 2]]'' and ''[[Super Mario Advance]]'', Luigi is one of four playable characters, where, like in ''The Lost Levels'', he could jump higher than anyone else, though he is the second weakest in the group behind [[Princess Peach|Princess Toadstool]]. This is the first game where Luigi isn't a recolor of Mario's sprite; instead, he is portrayed as taller than his brother. As ''Super Mario Bros. 2'' was a Western version of the Japanese game ''[[Yume Kōjō: Doki Doki Panic]]'', this was done so Luigi could fit the proportions of the character Mama.

====''Super Mario Bros. 3'' / ''Super Mario Advance 4: Super Mario Bros. 3''====
[[File:LuigiwalkgreenshellSMB3.gif|frame|left]]
In ''[[Super Mario Bros. 3]]'', Luigi is once again a palette swap of Mario; none of the original skills he had in the versions of ''Super Mario Bros. 2'' were carried over. Luigi has all of Mario's additional abilities, which includes carrying objects and the several power-up transformations, but his high jumps and low traction were removed. The only discernible differences are his green overalls and cap. Also, like in ''Super Mario Bros.'', Luigi can only be controlled by the second player in a 2-player game.

In this game's ''Super Mario All-Stars'' remake and ''[[Super Mario Advance 4: Super Mario Bros. 3]]'', Luigi is made taller than Mario (excluding his Statue form in ''Super Mario All-Stars''). The GBA version also gives him his [[scuttle]] from ''Super Mario Bros. 2'' and fireball physics from ''Super Mario World: Super Mario Advance 2'' in [[World-e]]; these properties can also be applied to the main game by scanning the [[Luigi Power Up!|yellow switch card]]. Owing to this, the Japanese key art for the card features Luigi on it.

====''Super Mario World'' / ''Super Mario World: Super Mario Advance 2''====
[[File:SLW.png|frame|left|Luigi's sprites]]
Luigi appears in ''[[Super Mario World]]'' again as a palette swap of Mario, having his brother's abilities and properties, and can only be played by the second player in a 2-player game. While his appearance was updated in the [[Super Nintendo Entertainment System|SNES]] rerelease, ''[[Super Mario All-Stars + Super Mario World]]'', his attributes stayed the same, though his actions differed from Mario's. In the GBA port, ''[[Super Mario World: Super Mario Advance 2]]'', Luigi regained his high jump and low traction attributes and can be switched out with Mario during the single player adventure, while his appearance borrowed elements from his design in ''Super Mario Bros. 2''.
{{br}}

====''Super Mario 64 DS''====
[[File:Luigi Artwork - Super Mario 64 DS.png|thumb|upright=0.66|Artwork of Luigi from ''Super Mario 64 DS'']]
While he was originally supposed to appear in the final version of ''[[Super Mario 64]]'',<ref>[https://iwataasks.nintendo.com/interviews/wiiu/super-mario-3d-world/0/6/ Iwata Asks: Super Mario 3D World - A Culmination of 3D Super Mario]. Retrieved April 30, 2023.</ref> Luigi appears in its remake, ''[[Super Mario 64 DS]]'', instead as an unlockable character. (''[[Nintendo Power]]'' theorized on one of the cards that came with volume 94 that he missed the original game because he was busy preparing for ''[[Mario Kart 64]]''.)<ref>@TheUltiMarioFan (May 15, 2021). [https://twitter.com/TheUltiMarioFan/status/1393768202522484740 "''All 8 Mario Kart 64 Nintendo Power cards''"]. ''Twitter''. Retrieved March 4, 2022.</ref> Luigi was one of the characters accompanying Mario to [[Peach's Castle]], along with [[Wario]]. However, [[Bowser]] trapped everyone inside the castle walls and paintings, with Luigi and the other heroes being locked behind a door with the [[Luigi Key|key]] to his door being guarded by [[King Boo]]. To unlock Luigi, Mario has to go to the top floor of [[Big Boo's Haunt]] and jump into the Luigi painting, which brings Mario to the [[Big Boo Battle]] course. Defeating King Boo (who refers to himself as Big Boo in-game, but wears a crown differentiating him from the common boss in the stage) rewards the player with the key needed to unlock Luigi. Once Luigi is unlocked, [[Luigi Cap|Luigi's Cap]]s can be found on every course after he has been rescued. The Luigi's Cap allows the wearer to mimic Luigi's appearance, attributes, and abilities perfectly, save for his voice. Through standard means, Luigi is the only character who can save [[Wario]] from [[Chief Chilly]]'s grasp, as he is the only character who can walk through the mirror in the [[Snowman's Land]] room by using his invisibility power to get to Wario's painting. While Luigi is needed to collect certain [[Power Star]]s, he is not required to complete the game.

[[File:WhompKingSM64DS.png|thumb|left|Luigi battling the [[Whomp King]]]]
The instruction booklet for ''Super Mario 64 DS'' says that he has the greatest agility, and Luigi does have great midair acceleration, letting him change his momentum easily after jumping. However, Luigi actually has a slower top speed than Mario (except in water) and is completely unable to wall jump. Luigi can swim faster than the other characters. Contrary to popular belief and his reputation from other games Luigi does not jump higher than Mario, with a notable exception: If Luigi performs a backward somersault, he does a very high [[Spin Jump]], like what happens when any of the characters jump on a [[Fly Guy]] or [[Spindrift]]. His attacks do the same amount of damage to enemies as Mario's, but he moves a little slower while carrying enemies and objects. Luigi can additionally [[scuttle]] for a short period of time after his normal jump or double jump, and he can run on water for a few seconds due to being lighter on his feet. Luigi's ability from a [[Power Flower (Super Mario 64 DS)|Power Flower]] is to turn [[Vanish Mario|transparent]], similar to the power Mario gets in the original game when wearing the [[Vanish Cap]]. This ability allows him to run through enemies and certain interfaces such as steel grates; however, Vanish Luigi cannot go through ice, unlike Vanish Mario.

All of Luigi's [[minigame]]s from the [[Rec Room (Super Mario 64 DS)|Rec Room]] revolve around gambling games. Luigi acts as the dealer in all of the card games, and he does not wear his usual attire, instead wearing a white shirt with a black vest and a green bowtie.
{{br}}

====''New Super Mario Bros.''====
[[File:NSMBDS Luigi Jumping Artwork.png|thumb|80px|left|Artwork of Luigi from ''New Super Mario Bros.'']]
In ''[[New Super Mario Bros.]]''{{'}}s main story, Luigi controls identically to Mario to ensure that both players have the same attributes in the multiplayer Mario vs Luigi mode. To play as Luigi, the player needs to hold down the {{button|ds|L}} and {{button|ds|R}} Buttons when selecting a file. If inputted correctly, Luigi's voice is then heard. While the code is revealed to the player after the credits roll, it can be used at any time. 

Luigi is also playable in the multiplayer mode, "Mario vs. Luigi." Here, he and Mario compete to see who can collect the most [[Big Star]]s. In DS Multi-Card play, the player who selects Mario is the host and the player who selects Luigi is the guest. In DS Download Play, the player with the cartridge is the host regardless of whom they choose.

In the minigame mode, three of Luigi's minigames from ''Super Mario 64 DS'' return under the category "Table": [[Memory Match (Super Mario series)|Memory Match]], [[Picture Poker]], and [[Pair-a-Gone]]. Luigi's appearance and role in these minigames is the same as in ''Super Mario 64 DS''. Luigi also appears in the [[Whack-a-Monty]] and [[Wanted!]] minigames.

====''Super Mario Galaxy''====
{{quote|I knew I could rely on you, bro!|Luigi|Super Mario Galaxy}}
[[File:LuigiGalaxy.png|thumb|upright=1.3|Luigi looking up at [[Baby Luma|Luma]] in ''Super Mario Galaxy'']]
Luigi appears in ''[[Super Mario Galaxy]]'', both as an NPC and as an unlockable character. When Bowser abducts [[Peach's Castle]], Luigi and the [[Toad Brigade]] are apparently inside, though they all soon escape and end up getting lost in space. Luigi is found imprisoned in the [[Ghostly Galaxy]] as the goal of [[Luigi and the Haunted Mansion|the first star]]. After rescuing him, Luigi goes out on his own in search of the [[Power Star]]s appearing in three different galaxies: the [[Good Egg Galaxy]], the [[Honeyhive Galaxy]], and the [[Battlerock Galaxy]]. Rescuing him in his respective missions rewards the player with a Power Star or, in the Battlerock Galaxy's case, a [[Green Star]]. When Luigi is not actively seeking Power Stars, he can be found in the [[Garage (Super Mario Galaxy)|Garage]] of the [[Comet Observatory]].

After the player collects all 120 [[Power Star]]s and defeats Bowser again, the player has to play the entirety of the game again, this time as Luigi. Luigi has different attributes and controls differently than Mario: he runs faster, but takes longer to build speed and is harder for him to stop running, he can jump higher and farther, and the air meter depletes faster when [[spin]]ning underwater. [[Cosmic Mario|Cosmic Luigi]] is also faster and takes different routes than Cosmic Mario. Additionally, the names of the stars that have "Mario" in their title are changed to "Luigi".

[[File:MLNPC.png|thumb|left|''(Left to right)'' Comparison of models for Mario, playable Luigi, and non-playable Luigi]]
While Luigi is the controlled character, the NPC Luigi in the game is not switched out, essentially having two Luigis in the game. While the playable Luigi is adjusted to fit Mario's build for gameplay purposes, the NPC Luigi is slightly taller and colored darker, matching Luigi's actual proportions. When the playable Luigi first rescues the trapped Luigi in the Ghostly Galaxy, the NPC Luigi dismisses the player as someone who happens to look like him. When the player rescues the NPC Luigi in three rescue missions, the NPC Luigi refers to the player as "me" (for example, "I knew I could rely on... me!"). When the NPC Luigi is in the Garage and the player talks to [[Rosalina]], she refers to both Luigis as "twins". When the [[Mailtoad]] has mail, the letters are addressed to Mario as usual instead of Luigi, causing the Mailtoad to feel bad for Luigi. Additionally, some of the letters contain 20 [[1-Up Mushroom]]s instead of the usual 5.

====''New Super Mario Bros. Wii''====
{{quote|Phew. Made it!|Luigi|New Super Mario Bros. Wii}}
[[File:NSMBW Luigi Jumping Artwork.png|thumb|upright=0.66|Luigi jumping in ''New Super Mario Bros. Wii'']]
Luigi appears in ''[[New Super Mario Bros. Wii]]'' as a main character, along with Mario, a [[Blue Toad (character)|Blue Toad]], and a [[Yellow Toad (New Super Mario Bros. series)|Yellow Toad]]. During any of the modes, player one is always Mario and players two through four can choose to be either Luigi or one of the Toads; however, Luigi is also playable in single-player mode, done by activating the [[Super Guide]] and pressing {{button|wii|+}} to take control of him. Luigi's and the Toad's properties are all the same as Mario's, meaning Luigi does not have his unique attributes like the higher jumps or low traction. Luigi is slightly taller than the other characters, however, making him easier to get hit by enemies above him. In the ending, he arrives alongside the Blue and Yellow Toads in Hot Air Balloons and has Mario and a newly-rescued Princess Peach enter his hot air balloon. However, he accidentally locked himself out of his hot air balloon while distracted waving goodbye to the Toads, having it take off without him.

If the player(s) die enough times in a stage, a [[Super Guide Block]] appears. Hitting it activates the [[Super Guide]] where a computer-controlled Luigi plays through the stage for the player. This Luigi only attempts to get to the end of the stage, usually avoiding any secrets or unneeded power-ups.

====''Super Mario Galaxy 2''====
{{quote|Hey, [[Mario|Bro]]! I'm all over the place these days, exploring the universe!|Luigi|Super Mario Galaxy 2}}
[[File:SMG2 Luigi.png|thumb|left|upright=1.1|Luigi in ''Super Mario Galaxy 2'']]
Luigi appears in ''[[Super Mario Galaxy 2]]'' where he is an unlockable playable character. His attributes and controls are retained from the first ''Super Mario Galaxy''. After the player collects 30 [[Power Star]]s and completes [[Bowser's Big Lava Power Party]], Luigi can be found at the beginning of some levels. If Mario talks to Luigi, he asks Mario if he can get the Power Star instead and accepting his offer lets the player control Luigi instead of Mario until the player completes or exits the current mission. Completing missions with Luigi unlocks [[Ghost (Super Mario Galaxy 2)|staff ghosts]] for that current mission. The ghosts appear as Luigi and begin moving to a particular spot in the stage once the player touches them. If the player uses the [[Co-Star Luma]] to spin in front of Luigi when he appears in a galaxy, he releases several [[Star Bit]]s.

Once the player completes [[Bowser's Galaxy Generator]], they can alternate between using Mario or Luigi by way of entering the large door behind where the player starts on [[Starship Mario]]. The [[Mailtoad]] receives a letter from Luigi telling the player about the option, signifying when the option becomes available. Also, while the player is playing as Luigi, the [[Tip Network]] signs and the [[Super Guide|Cosmic Guide]] do not appear.

====''Super Mario 3D Land''====
{{quote|Help me!|Luigi|Super Mario 3D Land}}
[[File:Kitsune Luigi.png|thumb|left|150px|Artwork of [[Tanooki Mario|Kitsune Luigi]] from ''[[Super Mario 3D Land]]'']]
[[File:LuigiSM3DL2.png|thumb|upright=1.1|Luigi in [[World 7-5 (Super Mario 3D Land)|World 7-5]]]]
In ''[[Super Mario 3D Land]]'', Luigi is an unlockable character. To unlock Luigi, the player has to rescue him in [[Special 1-Castle]], after which Luigi becomes playable. To switch between Mario and Luigi, the player has to tap either the "M" or "L" icon (depending on which brother is currently being played as) on the bottom screen during the level select map screens.

In term of controls, Luigi controls much like how he does in ''[[Super Mario Bros.: The Lost Levels]]'' and ''[[Super Mario Galaxy]]'': Luigi has a higher jump than Mario, but lower traction, causing him to slide. Luigi can use all of the same power-ups as Mario, though when collecting a [[Super Leaf]], instead of turning into [[Tanooki Mario|Tanooki Luigi]] like in ''Super Mario Bros. 3'', he gains a suit that looks like a kitsune, which is a Japanese fox. Most other languages, including the Japanese version, as well as English versions of later games, call this form Kitsune Luigi. As [[Statue Mario|Statue Luigi]], he is depicted with his right hand raised instead of his left like Statue Mario.
{{br}}

====''New Super Mario Bros. 2''====
[[File:LuigiNSMB2.png|thumb|125px|Luigi as he appears in ''New Super Mario Bros. 2'']]
In ''[[New Super Mario Bros. 2]]'', Luigi is an unlockable character in single-player mode and is the character for player 2 in Co-Op Mode. Like with the other ''New Super Mario Bros.'' series of games, Luigi's physics and controls are the same as Mario's. Luigi's [[Raccoon Mario|Raccoon appearance]] appears similar to his Kitsune form from ''Super Mario 3D Land'', taking on the ears and tail of the fox, and Luigi turns silver instead of gold when under the effects of the [[Gold Flower]]. Both forms are to differentiate him from Mario and both appearances are purely cosmetic; they do not affect the power-ups' properties at all. 

Luigi is unlocked for the single-player mode after clearing [[World 6-Bowser's Castle]]. The code is the same as in ''New Super Mario Bros.'' ({{button|3DS|L}} + {{button|3DS|R}}). Luigi is not playable in Coin Rush mode.

====''New Super Mario Bros. U'' / ''New Super Mario Bros. U Deluxe''====
[[File:NSLU Luigi and Yoshi Artwork.png|thumb|125px|left|Luigi riding [[Yoshi]] in ''New Super Luigi U'']]
Luigi appears as a playable character in ''[[New Super Mario Bros. U]]'' and ''[[New Super Mario Bros. U Deluxe]]''. Like with ''New Super Mario Bros. Wii'', Luigi can usually only be controlled by players either two, three, or four as Mario is always player one, but he can also be playable in single-player mode by activating the [[Super Guide]] and pressing {{button|wii|+}}. However, Luigi can be controlled by player one in ''New Super Mario Bros. U Deluxe'''s main mode of ''New Super Mario Bros. U''. To make it easier on the players, Luigi controls like the other characters, with him and the two playable Toads having the same controls and attributes as Mario. 

In the opening title sequence of the game, Luigi moves along with the other characters, though in some rare cases, Luigi ends up tripping instead, causing him to mess up his [[Ground Pound]] action.<ref>https://www.youtube.com/watch?v=CBdQUWl7JeI</ref>

=====''New Super Luigi U''=====
To celebrate 2013 as the [[Year of Luigi]], Luigi appears as the main playable character in the expansion of ''New Super Mario Bros. U'' titled ''[[New Super Luigi U]]'', with Mario making no appearance at all in the expansion pack. In this game, Luigi is given his unique play style again; he jumps higher and farther than Mario, but has worse traction, as in other titles such as ''[[Super Mario Bros.: The Lost Levels]]''. This makes ''New Super Luigi U'' the only title in the ''New Super Mario Bros.'' series where Luigi has his unique attributes, until ''New Super Mario Bros. U Deluxe''. Consequently, the other characters jump higher as well.

''New Super Luigi U'', as part of 2013's [[Year of Luigi]], includes [[List of Luigi sightings in New Super Luigi U|Luigi sightings]]. These are images, statues, and 8-bit sprites of Luigi that are hidden in every level.

====''Super Mario 3D World'' / ''Super Mario 3D World + Bowser's Fury''====
{{quote|Ha ha! Luigi! Go green!|Luigi|Super Mario 3D World}}
[[File:Cat Luigi Artwork - Super Mario 3D World.png|150px|thumb|Cat Luigi's appearance differs from his friends', with the round ears, a spotted pattern, and a darker tipped tail not unlike a leopard, jaguar, or cheetah.]]
Luigi returns in ''[[Super Mario 3D World]]'' and its [[Nintendo Switch]] port ''[[Super Mario 3D World + Bowser's Fury]]'' as one of the default playable characters. As the game's cast is primarily based on ''Super Mario Bros. 2'', Luigi retains his attributes from that game, being able to jump higher and farther, while having low traction. Unlike with the other titles with simultaneous multiplayer, Luigi can be selected by player one. The power-ups Luigi uses also change to his color scheme accordingly, such as the [[Boomerang Mario|Boomerang Suit]] and [[Cat Mario|Cat Suit]] becoming green, and his [[Tanooki Mario|Kitsune Luigi]] form returns when he gets a [[Super Leaf]].

Luigi is also featured as the playable character in the game's [[Mario Bros. (game)#Luigi Bros.|''Luigi Bros.'']] minigame, a game identical to ''Mario Bros.'', but replacing Mario with Luigi as the main playable character. Player one's Luigi is colored similarly to his modern appearance, whereas player two's Luigi has the colors from the original game. Both Luigi's have the same physics and controls, which are carried over from the original game.

Like in ''New Super Luigi U'', [[List of Luigi sightings in Super Mario 3D World|Luigi sightings]] also appear in this game as part of the Year of Luigi. They are usually 8-bit sprites of Luigi and are hidden in most of the levels.

As [[Lucky Cat Mario|Lucky Cat Luigi]], his appearance is identical to that of the other characters in their Lucky Cat forms, but is shown with his left paw raised rather than his right one, much like with his [[Statue Mario|Statue form]]. This pose is commonly associated with businesses and owners wanting to bring in customers.

Although Luigi does not physically appear in ''[[Super Mario 3D World + Bowser's Fury#Bowser's Fury|Bowser's Fury]]'', the [[Fury Shadow]] resembles him. Additionally, the [[kitten]]s' colors other than the calico kitten match those of the playable characters' [[Cat Mario|Cat Suit]]s in ''Super Mario 3D World'' other than Mario, with the green one matching Luigi's. In addition, all of the Luigi [[Stamp|stamp]]s from the ''Super Mario 3D World'' mode appear and can be used in [[Snapshot Mode]].

Luigi appears as an unlockable [[Mystery Mushroom]] [[Costume Mario|costume]] in ''[[Super Mario Maker]]''. The costume can be unlocked either at random upon completion of the 100 Mario Challenge, or by scanning a compatible Luigi [[amiibo]]. His appearance is based on that of ''Super Mario Bros.'', except with his modern colors. The costume replaces some of the usual ''Super Mario Bros.'' sounds with sounds from ''[[Luigi's Mansion]]''. [[Fire Mario|Fire Luigi]] in his ''Super Mario Bros.'' sprite (though with a green shirt rather than a red) also appears on the splash screen of the game on Sundays and shoots a [[fireball]] at Mario, knocking him off-screen. When [[Big Mario]] is active, some of the enemies, such as [[Bowser Jr.]], tend to have Luigi ride on or replace them.

====''Super Mario Run''====
Luigi reappears in ''[[Super Mario Run]]'' as a playable character along with [[Mario]], [[Princess Peach]], [[Toad]], [[Toadette]], and the colored [[Yoshi (species)|Yoshi]]s. Luigi is an unlockable character. To unlock [[List of Kingdom Builder items in Super Mario Run|his house]], the player has to recruit 150 Green and Purple Toads each through Toad Rally, then spend 1000 coins to build the house. Luigi has his higher jump and scuttle in this game.<ref>https://www.youtube.com/watch?v=rKG5jU6DV70</ref> Along with Mario, Luigi has a small form, allowing him to be hit once before dying.

====''Super Mario Odyssey''====
[[File:Luigi Outfit Odyssey.jpg|thumb|left|Mario wearing Luigi's cap and outfit in ''Super Mario Odyssey'']]
[[File:SMO-Luigi Art.png|thumb|Luigi, as he appears in ''Super Mario Odyssey'']]
While Luigi was initially absent in ''[[Super Mario Odyssey]]'', his [[Luigi Cap|cap]] and outfit can be purchased and worn by Mario in any of the [[Crazy Cap]] shops. His cap costs 100 [[coin]]s while his suit costs 200. The aforementioned outfit and cap are also unlockable via the Luigi amiibo or by completing the game with a certain number of moons. The description for his hat reads, ''"The standard cap in vivid green. The L stands for "winner",'' while the description for his suit reads, ''"A bright, green version of an established classic. Green means 'lets-a-go!'"''

Luigi was added as a friendly NPC in the update released on February 21, 2018, where he hosts the new [[Balloon World]] minigame. He appears with a green polka dotted bow tie and a luggage hanging on his back with balloons attached to it, allowing him to float. On the luggage are various stickers from the [[Mushroom Kingdom (Super Mario Odyssey)|Mushroom Kingdom]] and a sticker with his emblem on it. Luigi's dialogue changes depending on the clothes Mario is wearing upon talking to him.

As of March 14, 2018, Nintendo began posting extra [[Hint Art]] on social media leading to locations of hidden Luigi sprites. If Mario [[Ground Pound|ground pound]]s on the exact spot as depicted in the Hint Art, a sprite of Luigi from ''[[Super Mario Bros.]]'' pops out of the ground (recolored to match his modern design, as seen in his Mystery Mushroom costume in ''Super Mario Maker'') and grants him 200 [[coin]]s the first time it is discovered. Upon emerging (or if ground pounded), it lets out a distorted cry, and if Mario throws [[Cappy]] at it, it spins into the air.

The way Luigi and his red, blue, and yellow balloons are positioned corresponds to the layout of the {{button|snes|a}}, {{button|snes|b}}, {{button|snes|x}} and {{button|snes|y}} buttons on the Japanese and PAL versions of the [[Super Nintendo Entertainment System#SNES Controller|SNES Controller]] when viewed sideways.
{{br}}

Depending on what Mario is wearing when talking to him, Luigi will comment on it:
*'''Black Tuxedo / Explorer Outfit / Builder Outfit / Golf Outfit / Chef Suit / Painter Outfit / [[Super Mario 64|Mario 64]] Suit / Mechanic Outfit / Classic Suit / [[Dr. Mario|Doctor]] Outfit / [[Waluigi]] Suit / [[Diddy Kong]] Suit / [[Wario]] Suit / [[Metal Mario]] Suit / [[Super Mario Sunshine|Sunshine]] Outfit / [[Topper]] Suit / [[Rango]] Suit / [[Hariet]] Suit / [[Spewart]] Suit:''' ''"Hey... Have I seen that outfit somewhere before...? Anyway, lookin' good, Bro!"''
*'''Boxer Shorts / Clown Outfit / Skeleton Suit / [[Gold Mario]] Suit / Zombie Outfit / 8-Bit [[Mario]] Cap:''' ''"Bro! You startled me! That outfit is kinda, ummm... How can I put this? I mean, it looks good on you! It looks good, but uhh... Yeah..."''
*'''Luigi Suit:''' ''"Huh? What? Another... me?! No, wait. Is that you, Bro? Whoa, you really threw me for a loop there!"''
*'''[[Bowser]]'s Tuxedo / Bridal Gown / Mario's Tuxedo:''' ''"Whoa, Bro, you're getting married?! AND YOU DIDN'T TELL ME?! Oh, you're just wearing the outfit? For, like, fun? Huh."''

[[File:SMM-SMB-WeirdMario-Door-25.png|thumb|150px|Small Luigi in the ''Super Mario 3D World'' style]]
Luigi appears in ''[[Super Mario Maker 2]]'' as a playable character. Luigi is given a builder outfit of his own, which is identical to Mario's but with dark green overalls. Luigi also appears in the game's Story Mode when the player fails a course twice and he offers to either complete the course for them, or parts to make the stage easier.

He also appears in two of the opening sequences. In the first opening, Mario, Toad, and Toadette walk towards the game's logo, notice the number "2" is missing, and when they hit it together, Luigi falls (with the number "2" landing on the logo) and they proceed to leave. In the second opening as of the version 1.1.0 update, Luigi is seen with a [[Key]]; once he arrives at the [[Key Door]], Mario, Toad, and Toadette are there next to it and slowly approach Luigi, who then runs away with the Key, causing the three to chase him and take the Key by force off-screen. Afterwards Mario collects the Key and opens the Key Door, they proceed inside, and as the Key Door shuts, the number "2" falls on the logo.

Luigi's ''Super Mario Bros.'' Small form sprite may also appear if a Warp Door is knocked in the ''Super Mario 3D World'' style, akin to that game's Luigi sightings.

==== ''Super Mario Bros. 35'' ====
Luigi appears in ''[[Super Mario Bros. 35]]'' as an unlockable character. Luigi can be played as by holding {{button|switch|L}} after clearing every course at least once. He functions the same as Mario. He is also featured in multiple player icons.

====''Super Mario Bros. Wonder''====
{{new subject|section=y}}
Luigi appears as one of the playable characters in ''[[Super Mario Bros. Wonder]]''.<ref>Nintendo of America (June 21, 2023). [https://youtu.be/JStAYvbeSHc Super Mario Bros. Wonder - Nintendo Direct 6.21.2023]. ''YouTube''. Retrieved June 21, 2023.</ref>

===''Super Mario Bros.: Peach-hime Kyūshutsu Dai Sakusen!''===
[[File:AnimeLuigi.png|thumb|upright=1.1|Luigi laughing uncontrollably from a laughing shroom.]]
The first animated Luigi appears in the anime movie ''[[Super Mario Bros.: Peach-hime Kyūshutsu Dai Sakusen!]]'', where he was voiced by [[Yuu Mizushima]]. His color scheme in the movie is different from the games, as he is wearing a blue cap and overalls with a yellow shirt (and a red shirt in the promotional artwork for the anime), although at the time of ''Peach-hime Kyūshutsu Dai Sakusen!''{{'}}s creation, Luigi had not yet been given a consistent palette and his current color scheme had not been introduced in-game. The anime depicts Luigi as simple-minded opportunistic treasure hunter, focused on profits and characterized by his pickaxe and shovel, both of which he uses to mine for [[coin|gold coin]]s (although Mario has also shown interest in collecting the treasures from the kingdom). Luigi is often distracted and left adventuring with Mario and [[Haru-ōji|Kibidango]] to search for coins, though he usually ends up helping them progress in various ways. Luigi in the anime is also noticeably more serious and less dreamy than Mario, and he seemed to lack his brother's almost otherworldly connection to Princess Peach.

===''Mario Golf'' series===
{{quote|Oh dear... I've practiced, but nobody play with Luigi. Will you play with me?|Luigi|Mario Golf: Toadstool Tour}}
[[File:Luigi Artwork - Mario Golf World Tour.png|thumb|left|upright=0.85|Luigi as he appears in ''Mario Golf: World Tour'']]
Luigi has appeared in every game of the ''Mario Golf'' series. His first appearance was in ''[[Family Computer Golf: Japan Course]]'', followed by ''[[Family Computer Golf: U.S. Course]]'' and ''[[NES Open Tournament Golf]]''. In the latter two games, Luigi wears green and white striped overalls and cap along with a blue shirt with white stars imprinted on it, and are the only games to show Luigi in this outfit. Gameplay-wise, there are no differences between him and Mario.

====''Mario Golf''====
Luigi appears in ''Mario Golf'' as a default character in the [[Mario Golf (Nintendo 64)|Nintendo 64 version]] and an unlockable character in the [[Mario Golf (Game Boy Color)|Game Boy Color version]]. He is one of the first characters that can be unlocked in the [[Game Boy Color]] version by beating him on the "Get Character Mode". He had a unique course (in the sense that it was the only course in the game set up like a mini-golf course) named [[Luigi's Garden]]. At his strongest, Luigi can hit the golf ball up 220 yards and his shot type is "Fade".

====''Mario Golf: Toadstool Tour''====
Luigi made his fourth ''Mario Golf'' appearance in ''[[Mario Golf: Toadstool Tour]]'' as a default character. In this game, he has a fade with low trajectory and can hit 207 yards, or 240 when he is a starred character. The low trajectory of his shots make difficult for his ball to go past obstacles, but it also makes it less affected by the wind, both positively and negatively. In comparison to Mario, his spin is noticeably weaker, but he has good impact and much better control over the ball's trajectory.

During the opening cinematic, Luigi and Mario examine a trophy before Peach and Daisy call them for play time. After Peach, Mario, Daisy make their moves, Luigi is last in line to make his shot, which strikes the flagpole attached to the hole, which rallies the rest of Luigi's crew. Later in the cinematic, Luigi and the rest of the quartet are seen strolling around in the wilderness until they see Bowser's Castle in the distance. An unexpected explosion prompts Luigi and the rest of the crew to cover their eyes before the camera pans out.

====''Mario Golf: Advance Tour''====
Although he is not a default character in ''[[Mario Golf: Advance Tour]]'', Luigi is unlockable by linking the game with ''Mario Golf: Toadstool Tour''. His stats are about the same as in ''Toadstool Tour'', hitting 206 yards instead of 207.

====''Mario Golf: World Tour''====
Luigi is a default playable character in ''[[Mario Golf: World Tour]]''. Yet again, he has a low shot with a fade. His star rank is obtained when the player completes a match challenge in [[Cheep Cheep Lagoon (golf course)|Cheep Cheep Lagoon]], and his costume is unlocked by earning 50 scorecard badges on Castle Club courses.

====''Mario Golf: Super Rush''====
Luigi reappears as a playable character in ''[[Mario Golf: Super Rush]]'', sporting a golfing outfit. Like his brother Mario, he is a Speed character with average stats. His Special Shot is known as the Ice Flower Freeze while his Special Dash is known as the Speed-Skate Dash. While Luigi uses either his Special Shot or his Special Dash, he will use an [[Ice Flower]] to become [[Ice Mario|Ice Luigi]]. Despite Ice Luigi doing a skating motion while dashing, he cannot skate over water or lava unlike in ''Super Mario Galaxy'', where he will be penalized instead. When Luigi uses his Special Shot, his ball will turn into an [[Ice Ball]], and when the golf ball lands, it causes the surrounding area to become frozen. The ice from Luigi's Special Shot and Special Dash causes other players to slip when walked on. Moreover, the frozen area causes golf balls to roll longer and bounce higher than usual. The frost surrounding the golf ball will linger temporarily even after using the Special Shot, meaning that it still has the property of reduced friction.

===DIC cartoons===
[[File:SMWLuigi.png|thumb|upright=0.8|Luigi as he is seen in the ''Super Mario World'' animated series]]
Luigi appeared in all ninety-one episodes of the three cartoon series produced by [[DIC Entertainment]], though [[Mario]] only appeared in ninety episodes. In these cartoons, he was given green eyes instead of the usual blue that he has in the games. Luigi is the only character to appear in every episode of the DIC ''Super Mario'' cartoons.

====''The Super Mario Bros. Super Show!''====
{{quote2|Me?! But there- B-b-but I can’t! I'm-I'm gonna have a baby!|Luigi|</span>"[[King Mario of Cramalot]]"<span>}}
In ''[[The Super Mario Bros. Super Show!]]'', Luigi, portrayed by [[Danny Wells]], is seen living in [[Brooklyn]] together with Mario in the live-action segments. Like his brother, Luigi works as a plumber, running [[Mario Brothers Plumbing]] together with him. The episode [[Plummers Academy]] shows that he graduated from the [[Brooklyn Plumbers Academy]] together with Mario. The live-action segments show the two as having gained a reputation for their plumbing skills, even being awarded the title [[Plumbers of the Year]] in the segment of the same name. In the cartoon segments of the show, Luigi regularly joins his brother in various adventures in the [[Mushroom Kingdom]]. In the cartoon segments, Luigi is depicted as cowardly and overly cautious, a trait he later shows in the ''[[Luigi's Mansion]]'' and [[Mario & Luigi (series)|''Mario & Luigi]] games.

====''The Adventures of Super Mario Bros. 3''====
{{quote2|How can we help America when we can't even help ourselves? They've got us triple-guarded!|Luigi|</span>"[[Reptiles in the Rose Garden]]"<span>}}
[[File:Luigi-CasanovaKoopa.jpg|thumb|left|Luigi as Kassanova Koopa]]
Luigi is played by [[Tony Rosato]] in the two cartoon follow-ups to the ''Super Show'': ''[[The Adventures of Super Mario Bros. 3]]'' and ''[[Super Mario World (television series)|Super Mario World]]''. The former is almost exactly like the ''Super Show'', except the [[Koopalings|Koopa Kids]] join their father in making trouble for Luigi and the others. Once again, Luigi is depicted as a cautious and timid character; easily startled and reluctant to do anything dangerous, unless it means saving others.

In the episode "[[The Beauty of Kootie]]," '''Kassanova Koopa''' is what Luigi turned into to trick [[Wendy O. Koopa|Kootie Pie]] into letting [[Toad]], [[Princess Peach|Toadstool]], and the [[Mushroom King|King]] of [[Desert Land]] free. Kootie tricked Mario by having her brother [[Larry Koopa|Cheatsy]] change her into a human so she could flirt with him and distract him in order to carry out their plan. After the trick was revealed and the Mario Brothers got away, Mario used a swiped [[magic wand]] to transform Luigi into Kootie's "dream reptile" as a distraction. The trick worked for awhile, but after Kassanova Koopa tricked Kootie Pie into releasing the prisoners and Kootie started kissing him, she accidentally activated her wand. Subsequently, Luigi was reverted into his true state, which made Kootie Pie scream and chase him with Cheatsy behind her.

====''Super Mario World''====
{{quote2|It's all right! He wants to shake hands! He wants to be friends!!|Luigi|</span>"[[Rock TV]]"<span>}}
The [[Super Mario World (television series)|''Super Mario World'' television series]] shifts the setting from the [[Mushroom Kingdom]] to [[Dinosaur Land|Dinosaur World]], but once again, it is relatively the same as the earlier cartoons, with Mario, Luigi, and Princess Toadstool stopping the evil plots of King Koopa and his Koopa Kids. However, the heroes are now aided by the dinosaur [[Yoshi]] (replacing Toad), who was actually discovered by Luigi, who found an [[Yoshi's Egg|egg]] after falling down a waterfall. When he hatched, Yoshi affectionately called Luigi [[Mama Luigi]].

===''Amada Anime Series: Super Mario Bros.''===
[[File:AnimeLuigiTwo.jpg|thumb|upright=0.66|left|Luigi and Koopa in the ''Super Mario'' anime series]]
Luigi also appears in another anime, called the ''[[Amada Anime Series: Super Mario Bros.]]'', where he is depicted as wearing his traditional blue overalls and green shirt. Luigi only appears in the last story of the ''Super Mario'' anime series film, ''[[Super Mario Shirayuki-hime|Shirayuki-hime]]'' appearing just in time to save Mario and Princess Peach from King Koopa.

===''Super Mario World: Mario to Yoshi no Bōken Land''===
[[File:SMWMAYALLuigi.png|thumb|Luigi in ''Super Mario World: Mario to Yoshi no Bōken Land'']]
Luigi is a main character in the interactive OVA ''[[Super Mario World: Mario to Yoshi no Bōken Land]]''. He is part of a group trying to rescue Princess Peach from King Koopa. His appearance is notable for being one of the earliest examples of his cowardly personality - preceded by his appearances in the DIC ''Super Mario'' cartoons - depicting him and Yoshi initially being too scared to enter a [[Ghost House]]. He also gets easily angered when Mario triggers an explosion when Luigi is in blasting range, and everyone laughs at him, causing him to abandon the mission. However, he eventually overcomes this through his love for his brother and Princess Peach and comes to the rescue when Mario is having trouble fighting King Koopa.

===''Super Mario Bros.'' pinball machine===
[[File:SMB Pinball-Lower Playfield View.jpg|thumb|left|150px|Luigi next to Mario and two bumpers]]
Luigi appears in the ''[[Super Mario Bros. (pinball)|Super Mario Bros.]]'' pinball machine on the front artwork, where he is depicted to be held captive in the world six [[Castle]] by [[Wart]], despite the fact that Luigi is never held captive in ''[[Super Mario World]]'' (the game on which the machine is based) and Wart never appears in said game at all. He also appears in the playfield next to [[Cape Mario|Caped Mario]] and between two bumpers.
{{br}}

===''Mario Kart'' series===
{{quote|Oh yeah, can't stop Luigi!|Luigi|Mario Kart 8}}
[[File:MK8-Line-Luigi-Wave.gif|thumb|left|150px|[[LINE]] sticker of Luigi waving in his Pipe Frame]]
[[File:Luigi Artwork - Mario Kart 8.png|thumb|175px|Luigi in ''[[Mario Kart 8]]'']]
Luigi has appeared in every ''Mario Kart'' game to date. Throughout all his appearances, he is classified as a medium weight, making him a balanced racer, like Mario. 
====''Super Mario Kart''====
In ''[[Super Mario Kart]]'', a computer-controlled Luigi often uses [[Super Star]]s as his item of choice. 

====''Mario Kart 64''====
In ''[[Mario Kart 64]]'', Luigi gains a course of his own called [[N64 Luigi Raceway|Luigi Raceway]], which is the first race of the [[Mushroom Cup]] and, consequently, the first race of the game. 

====''Mario Kart: Super Circuit''====
Luigi returns in ''[[Mario Kart: Super Circuit]]'' with his own [[GBA Luigi Circuit|race course]] in the [[Lightning Cup]]. Notably, Luigi uses his ''Mario Kart 64'' Japanese voice-overs in all versions of ''Super Circuit''.

====''Mario Kart: Double Dash!!''====
In ''[[Mario Kart: Double Dash!!]]'', Luigi has a special item, the [[Green Fireball]], as well as an unlockable personal kart, the [[Green Fire]]. [[Mario]] is his default partner. As in ''Mario Kart 64'', the first course in the game is [[GCN Luigi Circuit|Luigi Circuit]], but Luigi also has a battle course, which is his haunted [[GCN Luigi's Mansion|mansion]]. [[Baby Luigi]] also makes his debut playable appearance in the ''Mario Kart'' series here.

====''Mario Kart Arcade GP'' series====
Luigi also appears in the ''Mario Kart'' games for the arcade, ''[[Mario Kart Arcade GP]]'', ''[[Mario Kart Arcade GP 2]]'', and ''[[Mario Kart Arcade GP DX]]''. His and Mario's special character items are the [[Super Star]], [[Fireball]], [[Hammer]], and [[Chain Chomp]]. In ''Mario Kart Arcade GP 2'', his personal kart is a train-like vehicle while in ''Mario Kart Arcade GP DX'', his personal kart is the [[Vacuum Star]]. Luigi has also an alternate color which resembles [[Ice Mario|Ice Luigi]].

====''Mario Kart DS''====
In ''[[Mario Kart DS]]'', Luigi's personal karts are the [[Poltergust 4000]], the [[Streamliner]], and the [[Standard LG]]. Luigi's karts each offer all-around stats for the speed, acceleration, and handling categories, but with poor drifting abilities. A racecourse based on his [[DS Luigi's Mansion|mansion]] reappears as a course in the [[Mushroom Cup]], as well as the Luigi Circuits from ''Mario Kart: Super Circuit'' and ''Mario Kart: Double Dash!!'' in the [[Leaf Cup]] and [[Shell Cup]] respectively.

====''Mario Kart Wii''====
In ''[[Mario Kart Wii]]'', Luigi can use a variety of karts and bikes, although there are no personal karts. The only course based on Luigi in this game is [[Luigi Circuit (Mario Kart Wii)|Luigi Circuit]], the first course of the [[Mushroom Cup]]. Luigi adds a small speed boost to his karts, but his best bonus is the weight stat.

====''Mario Kart 7''====
Luigi reappears in ''[[Mario Kart 7]]''. He is once again a middleweight racer with relatively balanced stats. Luigi Raceway from ''Mario Kart 64'' and Luigi's Mansion from ''Mario Kart DS'' return as the first and last races of the Shell Cup respectively.

====''Mario Kart 8'' / ''Mario Kart 8 Deluxe''====
Luigi returns in ''[[Mario Kart 8]]'' as a playable character, though he does not have any courses based on him in this game. This is the first game in the main series since ''Super Mario Kart'' to not feature a course of any kind based on Luigi. Luigi also has a racing team in this game called [[Luigi Gusters]]. Luigi reprises his role in the game's enhanced port, ''[[Mario Kart 8 Deluxe]]''. Luigi's Mansion from ''Mario Kart: Double Dash!!'' also returns as a retro battle course in ''Mario Kart 8 Deluxe''. 

====''Mario Kart Tour''====
Luigi reappears in a playable role yet again in ''[[Mario Kart Tour]]'', where he was made available since the [[Halloween Tour (2019)|2019 Halloween Tour]] as a Super character; like his brother and [[Metal Mario]], the [[Fire Flower]] reappears as Luigi's special item.

Not counting [[Penguin Mario|Penguin Luigi]], [[Builder Mario|Builder Luigi]], [[#Dr. Mario series|Dr. Luigi]], and [[Cat Mario|Cat Luigi]], Luigi has five variants in the game, which are all classified as High-End drivers.
*The [[Mario Bros. Tour]] introduces a variant of Luigi based on his classic look in ''[[Super Mario Bros.: The Lost Levels]]'' known as '''Luigi (Classic)'''. He has the [[Lucky Seven]] as his special skill.
*The [[Berlin Tour]] introduces a variant of Luigi wearing traditional German clothes known as '''Luigi (Lederhosen)''' with the [[Triple Mushrooms]] as his special skill.
*The [[Paris Tour (2021)|2021 Paris Tour]] introduces a variant of Luigi wearing his painter outfit from ''[[Mario Kart Live: Home Circuit]]'' known as '''Luigi (Painter)''' or '''Painter Luigi'''<ref>[https://apps.apple.com/us/story/id1578823936 Mario Kart Tour Turns Two!] apps.apple.com (United States).

"'''''What we love:''' Scoring some of our all-time favorite characters, like Painter Luigi and Vacation Peach.''"</ref>. Like Luigi (Classic), he has the Lucky Seven as his special skill.

**The [[Mario vs. Luigi Tour (2023)|2023 Mario vs. Luigi Tour]] introduces a golden variant of Luigi (Knight), simply named '''Luigi (Gold Knight)''', with the [[Coin Box]] as his special skill.
Luigi also has his own [[Luigi Cup|self-named cup]] and [[Mario vs. Luigi Tour|Team Rally tours]] between him and his brother Mario.

===''Super Mario Adventures''===
[[File:Luigi in Super Mario Adventures.jpg|thumb|upright=0.55|left|Luigi in ''Super Mario Adventures'']]
The ''[[Super Mario Adventures]]'' comic serial's depiction of Luigi features him in a similar portrayal to his personality in the games and cartoons, however, he is often hungry and wanting to eat. In the first installment, Luigi wants to eat his lunch before working on repairing the Princess's horribly mangled plumbing, whining about his hunger as he grows frustrated with the job, while Mario cheerfully reconnects the pipes.  He gets very upset when Mario is bitten and falls onto his lunchbox, and as more pipes pop up around the brothers, Luigi wants to grab the remains of his lunch, but Mario drags him out of the castle.  Interestingly, Luigi is actually enticed by a Ghost House that Bowser has set as a trap for them, wanting to spend the night in it, while Mario tries to warn him that it is a trap.  Luigi rushes inside when Bowser lets loose the scent of a giant hunk of aged provolone cheese and starts eating it, oblivious to the Boos coming up behind him until Mario alerts him. It is also worth noting is that Luigi disguises himself as Princess Peach to infiltrate the Koopalings' hideout at one point, a strategy he would later use in ''[[Mario & Luigi: Superstar Saga]]''.

===''Mario is Missing!''===
{{quote|Right, I'll watch the back door. Be way careful M, Bowser's one rascally reptile. And remember, don't take candy from strangers.|Luigi|Mario is Missing!}}
[[File:Luigi Sprite MiM.png|frame]]
In ''[[Mario is Missing!]]'', Mario gets kidnapped by Bowser, prompting Luigi to begin an adventure to rescue him. In order to do so, Luigi has to recover stolen artifacts in order to figure out what [[Earth|real world]] city he is in so he can call [[Yoshi]] to leave and return to the main castle. While the gameplay and details of the game differ between versions, Luigi's role remains the same. This game marked Luigi's second solo game (after ''[[Luigi's Hammer Toss]]'') and he would not receive another one until ''[[Luigi's Mansion]]'', eight years later.

The PC version of the game has become infamous among fans and internet memes due to the sprite of Luigi, dubbed by fans as [[List of references on the Internet#Weegee|"Weegee"]].
{{br}}

===''Super Mario Bros.'' film===
{{quote|Nothing's impossible, Mario. Improbable, unlikely, but never impossible.|Luigi|Super Mario Bros. (film)}}
{{main|Luigi (film character)}}
Luigi is a main character in the [[Super Mario Bros. (film)|''Super Mario Bros.'' movie]], played by [[John Leguizamo]]. Here, Luigi is portrayed as a kind and courageous character, often jumping into trouble and making brash decisions due to his determination to protect and save [[Princess Daisy (film character)|Daisy]].

===''Mario & Wario''===
[[file:MWLuigiSprite.png|thumb]]
In ''[[Mario & Wario]]'' Luigi appeared as the level's [[goal]] and the player had to navigate the level to get to Luigi. Luigi himself does not do much aside from pacing at the goal while waiting for the player to arrive. Once the player does reach Luigi, he removes the bucket covering the player character's head.
{{br}}

===''Mario's Time Machine''===
[[File:Luigi MTMDX.png|thumb|left|Mario's doodle of Luigi in ''Mario's Time Machine'']]
In the PC release of ''[[Mario's Time Machine]]'', Luigi appears twice: once on the hint icon, reaching out his hand towards Mario, and as a doodle in Mario's journal, which Mario claims that he drew himself as he shows it to [[Jeff Griffeath]].

===''Hotel Mario''===

[[File:HM Luigi.png|thumb|This image accompanied by Luigi's "And ''you'' gotta help us!" is [[List of references_on_the_Internet#YouTube_Poop|an internet meme prevalent in YouTube Poop videos]].]]
Luigi is one of the main characters in the game ''[[Hotel Mario]]''. Princess Peach was retained as a "permanent guest" by Bowser, who turned the Mushroom Kingdom into his own personal resort. Luigi was controlled by the second player, his sprite being a palette swap of Mario and his controls being the same as Mario's once again. Despite this, the cutscenes feature Luigi with a different appearance.
{{br}}

===''Yoshi's Island'' series===
{{main|Baby Luigi}}
[[File:Marioparents.PNG|thumb|upright=0.85|The two babies with their family]]
In various entries of the ''Yoshi's Island'' series, Luigi and Mario appear as babies who are to be delivered to their parents via the [[Stork]], referred to as [[Baby Luigi]] and [[Baby Mario]], respectively. However, Baby Luigi is subject to being kidnapped by [[Kamek]] and taken to [[Baby Bowser]]'s [[Bowser's Castle|castle]], where he must be rescued by the [[Yoshi (species)|Yoshis]] and Baby Mario in order for him and his brother to be delivered to his parents.

Adult Luigi makes a small cameo in ''[[Yoshi's Story]]'' in the level [[Torrential Maze]] of the second world. His name is printed in the background of the stage.

===''Super Mario RPG: Legend of the Seven Stars''===
{{quote|I wanna be a great plumber like my brother Mario.|Luigi|Super Mario RPG: Legend of the Seven Stars}}
[[File:SMRPGCL.png|thumb|left|Luigi leading the [[victory parade|parade]]]]
In ''[[Super Mario RPG: Legend of the Seven Stars]]'', Luigi hosted the game's physical instruction booklet, only directly appearing at the start of the game's ending credits. There is a mention of him on [[Star Hill]], where a [[Wish Star]] states his wish; in the English version, he wants to be a great plumber like his brother Mario, but in the Japanese version, he merely states that he wants to help his big bro (only implying that it is Luigi's wish). The Japanese version contains additional references to Luigi, such as [[Garro]]'s description of [[A Plumber's Lament]] originally including the subject's well wishes toward his little brother, and as one of the possible answers to the [[Dr. Topper]] quiz, "Luigi" is an answer for the ultimate enemy in the adventure (instead of Bowser).

A [[List of Super Mario RPG: Legend of the Seven_Stars pre-release and unused content#Nintendo Power|pre-release screenshot]] showed Luigi (along with Mario and [[Mallow]]) attending a banquet hosted by [[Valentina]], suggesting he might have been playable or at least would've had a bigger role.

|size=100
|align=right
}}
Luigi appears in each of the ''Game & Watch Gallery'' titles, with his role changing based on the [[Game & Watch]] game being played.

In the ''[[Game & Watch Gallery]]'' minigame ''[[Fire (Game & Watch)|Fire]]'', Luigi assists Mario in trying to save passengers who are escaping from the top of a burning castle. In ''[[Oil Panic]]'', Luigi is normally sleeping. However, if Mario spills any oil on him, he wakes up and gets mad, and the player gets a miss.

In ''[[Game & Watch Gallery 2]]'', Luigi appears in ''[[Chef]]'' as one of the cooks who delivers food to Princess Peach.

In ''[[Game & Watch Gallery 3]]'', Luigi appears in ''[[Mario Bros. (Game & Watch)|Mario Bros.]]'', where he assists Mario in moving cakes onto a truck.

In ''[[Game & Watch Gallery 4]]'', Luigi retains his roles in ''Fire'', ''Chef'', and ''Mario Bros.'', as well as appearing in ''[[Rain Shower]]'' and ''[[Boxing]]''. In ''Rain Shower'', one of the characters that Mario has to keep dry is Luigi himself, who sleeps in the hammock in the upper left-hand corner. If a water balloon hits Luigi, he will wake up and get mad, earning Mario a miss. In ''Boxing'', Luigi has to face a [[Wiggler]], a [[Big Boo]], and [[Waluigi]] in a set of three different boxing matches.

===''Club Nintendo''===
Luigi also made several appearances in the [[Club Nintendo (magazine)|''Club Nintendo'']] comic series, usually as a companion of his brother, Mario. In the story "[[Super Mario: Im Rausch der Geschwindigkeit]]," however, Luigi worked as a policeman and actually imposed a fine on Mario when the latter was violating the speed limit of [[Brooklyn]] while riding Yoshi. Luigi also insisted on being called "Officer Luigi."

===''Mario Party'' series===
{{quote|Time to play!|Luigi|Mario Party 10}}
[[File:SMP - Luigi and Bob-omb artwork.png|thumb|left|Luigi's art from ''Super Mario Party'' references the [[Lit Potato]] minigame. [[:File:SMP PeachLuigiArtwork.png|Full art depicts Peach tossing the Bob-omb]].]]
Luigi has appeared in every [[Mario Party (series)|''Mario Party'']] installment to date and has been a playable character in each title, aside from ''[[Mario Party-e]]''. In the earlier ''Mario Party games'', his character color was green, but has been changed to blue starting in ''[[Mario Party 3]]'' (green is now specific to [[Yoshi]]). Like with other characters in the first ''[[Mario Party]]'', Luigi has his own board called [[Luigi's Engine Room]]. In ''[[Mario Party 2]]'' and ''Mario Party 3'', his favorite item is the [[Skeleton Key]], and his Duel Mode partner is a [[Goomba]]. Also in ''Mario Party 3'''s Story Mode, if the player is playing as the character they were supposed to duel, Luigi becomes the opponent. In ''[[Mario Party 4]]'', Luigi helps reclaim the player's birthday present; in ''[[Mario Party 5]]'', Luigi helps his friends save [[Dream Depot]]; in ''[[Mario Party 6]]'', he helps settle an argument between [[Brighton]] and [[Twila]]. In ''[[Mario Party 7]]'' he shares his Character Orb, the [[Fireball Orb]], with Mario and his partner is usually his brother. Whenever Luigi throws an orb, it has Luigi's [[emblem]] on it, which is a green letter L on a blue background. In ''[[Mario Party 8]]'', Luigi competes with his friends at the Star Carnival to win a year's supply of candy; in ''[[Mario Party 9]]'', he helps his friends recollect the [[Mini Star]]s. In ''[[Mario Party Advance]]'', Luigi (or Mario) is needed to complete the [[Mustached Hero!]] quest. During Toad Scramble in ''[[Mario Party: Star Rush]]'', if the player has Luigi on their team, he stomps on the Goombas in their way and grants the player use of the [[Jumpy Dice Block]]. Luigi has appeared in ''[[Mario Party: The Top 100]]'' as a playable character, and he reappears in ''[[Super Mario Party]]'' in a playable capacity. Luigi's Dice Block has three 1's, one 5, one 6, and one 7, either rolling very low or very high.

====''Super Smash Bros.''====
{{main-external|SmashWiki|Luigi (SSB)}}
In the first ''[[Super Smash Bros.]]'', Luigi is an unlockable character. He can be unlocked by completing the [[Break the Targets]] bonus game with all eight of the starter characters, followed by beating him on the [[Peach's Castle (Super Smash Bros.)|Peach Castle]] stage. Despite being a locked character, he always appears alongside Mario on Stage 4 of 1-P Mode and the How to Play tutorial. Luigi weighs 100 units just like Mario.

Luigi is one of the slowest characters in the game, on the ground and in the air (tied with [[Ness]] for the slowest running speed, and the lowest airspeed), as well as one of the lowest falling speeds. Luigi's attacks are either weaker than Mario's, or they deal the exact same damage. Keeping with his distinct gameplay in the ''Super Mario'' franchise, Luigi also has the lowest traction of any character, but has the highest jumps. Luigi's moves are mostly copied from Mario, though his copied moves have their distinctions. His standard special move is [[Green Fireball|Fireball]], which travels in a straight line through the air rather than across the ground like Mario's. His down special is [[Luigi Cyclone]], in which Luigi spins around rapidly; the move only hits twice but deals greater damage and knockback. Finally, his up special move is [[Super Jump Punch]], which only hits one time, but if it hits at the start of the move, it deals much greater damage and knockback. In addition, Luigi's taunt is a low, short kick that can damage opponents, making it the only taunt in the game that can deal damage.

====''Super Smash Bros. Melee''====
{{main-external|SmashWiki|Luigi (SSBM)}}
Luigi is also an unlockable character in ''[[Super Smash Bros. Melee]]''. To unlock him, the player has to either fight 800 VS matches or clear the first level of Adventure Mode with the seconds value on the timer being a 2 (ex. XX:X2<sup>XX</sup>). Upon clearing the later requirement, Luigi takes Mario's place in the following fight on [[Princess Peach's Castle (Super Smash Bros. Melee)|Princess Peach's Castle]]. Fighting 800 VS matches or clearing Adventure Mode while meeting the requirements brings the player to the [[Mushroom Kingdom II]] stage to fight Luigi. Defeating Luigi then unlocks him as a playable fighter. Luigi retains his physics from the previous installment, having the lowest traction in the game, the second-highest jump height (now surpassed by [[Falco]]), and somewhat poor mobility overall, while being a middleweight.

For this game, many of Luigi's moves were changed, increasing his distinction from Mario. Luigi's attack speed has majorly improved, and many of his attacks are now stronger than Mario's. Luigi has become faster on the ground, in exchange for a lower airspeed. In addition, his taunt, returning from ''Super Smash Bros.'', is now a [[meteor smash]] when used against opponents on or near the ledge. Luigi also gains a distinct side special move, [[Green Missile]], in which Luigi launches himself head-first into opponents. Unlike Mario, Luigi cannot [[Wall Jump]] in this game.

====''Super Smash Bros. Brawl''====
{{main-external|SmashWiki|Luigi (SSBB)}}
[[File:SubspaceIntro-Luigi.png|left|thumb|175px|Luigi's snapshot in The Subspace Emissary]]
In ''[[Super Smash Bros. Brawl]]'', Luigi appears as an unlockable character once more. To unlock him, the player must either play 22 Brawl matches, clear Classic mode without using a continue, or have him join the party in [[Super Smash Bros. Brawl#Subspace Emissary|The Subspace Emissary]] by clearing [[Subspace (Super Smash Bros. Brawl)|Subspace (Part 1)]]; with any of the former two methods, Luigi must be defeated on [[Luigi's Mansion (stage)|Luigi's Mansion]] to be unlocked. For this game, Luigi's appearance has been updated to reflect his current design, and his voice clips use his distinct voice, rather than being Mario's voice clips at a higher pitch like in the previous games. Once again, a few of Luigi's animations were changed to make him less identical to Mario. Like many other characters, Luigi's damage output was decreased from ''Melee''; despite this, his attacks remain stronger than Mario's.

For this game, Luigi is now lighter than Mario (weighing 97 units), rather than sharing his weight. He is also one of the few characters that is able to crawl. While few of Luigi's moves are changed in this installment, his [[Final Smash]] is [[Negative Zone]], in which Luigi creates a green void that deals a random status effect to any opponents caught in it.
=====The Subspace Emissary=====
[[File:LuigiNessBadges.png|thumb|left|upright=0.85|Luigi and [[Ness]] are revived by [[King Dedede]]'s badges.]]
Luigi first appears where he pretends to threaten and attack on-coming [[Waddle Dee]]s. They are harmless and make no move to attack him, but he is frightened by them nonetheless. From behind, he is attacked by [[King Dedede]], who slams Luigi with his mallet, sending him flying into the air. After he comes back down, he becomes a [[Trophy (Super Smash Bros. series)|trophy]]. A Western-style remix of the ''[[Luigi's Mansion]]'' theme plays during this segment. King Dedede places him on the road as bait for [[Wario]], who is coming down the road. Wario takes the bait, and King Dedede manages to steal Luigi along with the rescued princess and [[Ness]].

Later, Dedede places a special brooch on Luigi and the others. When [[Tabuu]] transforms everybody else into trophies, the brooches, which were revealed to be timer-based revival tools, turn Luigi and Ness back into living beings. Luigi and Ness then revive King Dedede. The unlikely trio set off to help out the others in Subspace. Luigi, along with Ness, then watches King Dedede battle [[Bowser]], and later help him convince Wario to join them. After they turn the trophies back to normal, they all face off against Tabuu.

====''Super Smash Bros. for Nintendo 3DS'' / ''Wii U''====
{{main-external|SmashWiki|Luigi (SSB4)}}
Luigi appears as a playable character in ''[[Super Smash Bros. for Nintendo 3DS]]'' and ''[[Super Smash Bros. for Wii U]]'' where, for the first time in the series, he is a default character. None of his moves have been changed from the previous game with the exception of his down throw, which is now a [[Ground Pound]] instead of a body slam; and Final Smash, which is now [[Poltergust 5000]]; when used, Luigi pulls out the vacuum, which sucks in opponents, damages them, and launches them back out.<ref>https://miiverse.nintendo.net/posts/AYMHAAACAADMUKlpzooN0A</ref> Luigi now also [[scuttle]]s during his jumping animation, making him more closely resemble his depiction in the main ''Super Mario'' franchise. Luigi's damage output has been lowered overall, but in exchange, his mobility is faster.

In this game, Luigi can use equipment to boost his stats at the cost of others. In addition to generic badges, Luigi, like Mario, can wear certain additional equipment such as shoes (speed), overalls (defense), and gloves (attack). Finally, Luigi can use alternate special moves, which function differently than the base moves.

====''Super Smash Bros. Ultimate''====
{{main-external|SmashWiki|Luigi (SSBU)}}
Luigi returns as an unlockable playable character in ''[[Super Smash Bros. Ultimate]]''. He has a new running animation, which is very similar to his running animation in ''[[Luigi's Mansion]]''. Like Mario, Luigi also receives a new walking animation. Aside from this, a few of his moves have changed, such as his up tilt and forward tilt. The former is an uppercut that goes straight upwards instead of a spinning uppercut (in the original ''Super Smash Bros.'') or a "paw swipe" with his fists (in subsequent games), while the latter is now a side kick instead of a roundhouse kick. Luigi also now uses his new [[Poltergust G-00]] for his grab and throws.<ref>[https://www.smashbros.com/en_US/blog/index.html?category=cat02_fighter_09 Smash Bros. Blog (09: Luigi)]</ref> The Poltergust G-00 functions as a tether grab and can be used in midair. Luigi's forward and back throws involve him slamming the opponent in multiple directions, while his up throw has him eject foes directly from the Poltergust G-00. Luigi also uses the Poltergust G-00 in his Final Smash. Luigi's up smash is nicknamed the Lead Headbutt, while his standard air is the Luigi Kick.

Luigi benefits from universal changes: his mobility has been made faster, no longer being below-average; his short hop timing and landing lag in his aerials are reduced, making them faster; he can directionally air dodge once again, improving his recovery; and he can use any ground attack out of a run and any aerial attack while holding onto ladders. Luigi's traction has been majorly improved, no longer being the lowest in the game, and is more in line with Mario's. Luigi's forward tilt and dash attack both deal more damage, his forward smash deals more knockback, and his down smash's clean hit is more likely to connect. His down tilt deals less damage, in exchange for having less ending lag.

Luigi appears in [[Simon Belmont|Simon]]'s debut trailer, "Vampire Killer", where he is walking through [[Dracula's Castle]] with his Poltergust while terrified of his surroundings. He attempts to ward off various approaching mummies with his Poltergust's flashlight, eventually hitting one of the mummies in the face with a plunger, which sticks for a few seconds before causing the Mummy to pursue Luigi in a rage, forcing him to flee. He then exits the door into another room, only to find a moving Medusa bust with glowing eyes, causing him to flee again before tripping and landing on his posterior. He then gets back up and looks up to see Death, who kills him with his Scythe as he is screaming. Death is then ambushed and warded off by Simon. At the end of the trailer, Luigi's soul attempts to reunite with his corpse, but as he does so, Carmilla's mask appears in the window next to him, causing him to scream.

Luigi briefly appears in [[Piranha Plant#Super Smash Bros. Ultimate|Piranha Plant]]'s reveal trailer, where he is seen dazed alongside a group of [[Yoshi (species)|Yoshi]]s.

Luigi is unlocked as the 33rd character to be unlocked via playing VS matches, completing Classic Mode as [[Mario]] or anyone within his unlock tree, being the fifth character in Mario's unlock tree, or getting him to join the player's party in World of Light.

On a side note, as with several other returning characters, Luigi's victory theme, which is the orchestral arrangement of the level clear theme from ''Super Mario Bros.'' (and is shared with Mario, Dr. Mario, and Peach, and in this game, Daisy) has been slightly shortened and sped up compared to the previous installments. 
=====Classic Mode route=====
Luigi's Classic Mode route has him fight dark or scary opponents, referencing his cowardly nature, which is most prevalent in the [[Luigi's Mansion (series)|''Luigi's Mansion'' series]]. Luigi's Classic Mode route's name also alludes to the ''Luigi's Mansion'' series, which has him fight ghosts.

===''Mario Tennis'' series===
[[File:Luigi - Mario Tennis Ultra Smash.png|thumb|Luigi in ''Mario Tennis: Ultra Smash'']]
Luigi also appears as a reoccurring character in the ''Mario Tennis'' cast. Through all titles, Luigi is an all-around tennis player like his brother, although he had better control and net play.

====''Mario Tennis''====
Luigi also gained a rival by the name of [[Waluigi]] in the [[Mario Tennis (Nintendo 64)|Nintendo 64 version of ''Mario Tennis'']]. He is an All-Around type character. During doubles tournaments, Luigi serves as Mario's partner, while Daisy serves as Luigi's partner if he takes the lead role.

During the intro, Luigi is seen walking in line with the other characters, showing greeting signs. After having a chat with Mario, Wario and Waluigi unknowingly appear, which sparks a rivalry between the two parties. When Bowser arrives, the turmoil cools down.

Luigi is one of the few characters to be initially playable in the [[Mario Tennis (Game Boy Color)|Game Boy Color version]].

====''Mario Power Tennis''====
In ''[[Mario Power Tennis]]'', [[Luigi's Mansion Court|his mansion]] appears as a court. His Offensive Power shot is the [[Squeaky Mallet]] and his Defensive Power Shot is the [[Poltergust Return]]. His default partner in doubles tournaments is Mario.

During the opening cinematic, Luigi is seen narrowly dodging the ball returned by Mario as both win a match against Wario and Waluigi. During the night of the final match, Wario and Waluigi reappear after Yoshi and Donkey Kong fail to show up. As Wario and Waluigi hurl a barrage of Bob-ombs, Luigi and Mario use their tennis rackets to knock back the explosives, which causes significant damage to the [[Peach Dome]] in recoil. Luigi escapes safe and unharmed, especially after Bowser's balloon caused an explosion that nearly wiped out the venue and the remaining inhabitants around it.

====''Mario Tennis: Power Tour''====
Luigi reprises his role as a playable character in [[Mario Tennis: Power Tour]], but is only playable in Exhibition Mode.

====''Mario Tennis Open''====
In ''[[Mario Tennis Open]]'', the [[Mii]]s can wear a uniform based on Luigi, as well as his costume, which is unlocked by winning the doubles Final Cup. 

====''Mario Tennis: Ultra Smash''====
Luigi reprises his role as a playable character in ''[[Mario Tennis: Ultra Smash]]'' as a balanced character. 

====''Mario Tennis Aces''====
In ''[[Mario Tennis Aces]]'', he wears tennis gear instead of his usual outfit by default, although his usual outfit could be unlocked by accumulating 2000 participation points in the January 2019 online tournament. In the game's Adventure Mode, Luigi is possessed by [[Lucien]], and Mario has to rescue him.

===''Paper Mario'' series===
====''Paper Mario''====
[[File:luigi parade.png|frame|Luigi dressed up to lead the parade at the end of ''Paper Mario'']]
At the start of ''[[Paper Mario]]'', Luigi accompanies Mario to [[Peach's Castle]] for her party. Once Bowser started lifting Peach's Castle into the sky with [[Bowser's Castle|his own castle]], Luigi escaped back to [[Mario Bros.' House|his house]], where he is found for the remaining duration of the game.

Luigi spent most of his time lamenting his own inactivity, begging for Mario to take him along and practice for future quests. With all his downtime, Luigi also built a basement in which he kept [[Luigi's Diary|a secret diary]] where he wrote about various things, such as how he disliked being left out of adventures with his brother. One notable entry in his diary had him dreaming about starring in his own game, foreshadowing his next solo quest, ''[[Luigi's Mansion]]''. Every time Mario gets a move upgrade, Luigi is in a different spot. Mario can use his new moves to enter or affect these areas, triggering some humorous dialogue with Luigi. In the ending, Luigi, learning how Mario got the Star Rod back from Bowser, deduced it was another adventure in the books despite days having passed since then. He also got another invitation to a party from Peach from Parakarry (who got an invitation himself), and then traveled with Mario to Toad Town before leaving him due to "important business", and citing he can't tell Mario due to it being top secret. He also leads the parade in the end credits, much like in ''Super Mario RPG''. Later in the game, a [[Duplighost]] tries to turn himself into [[Kooper]], but instead turns himself into Luigi.
;Tattle information
''He's Luigi. I don't have to say anything about him, do I? He's your brother!''

====''Paper Mario: The Thousand-Year Door''====
[[File:PMTTYD Talking to Luigi.png|thumb|220px|left|Luigi, telling [[Mario]] his first story]]
[[File:PMTTYD Luigi in audience.png|thumb|150px|Luigi in the audience]]
While Mario is on his mission to collect the [[Crystal Stars]] in ''[[Paper Mario: The Thousand-Year Door]]'', Luigi is on a mission of his own. After every chapter in the game, Mario could find Luigi and listen to his story in [[Rogueport]]. When telling Mario the story, Luigi constantly exaggerated to make the story better and to make himself sound much more heroic; Luigi's partners (including [[Blooey]], [[Hayzee]], [[Jerry (Paper Mario: The Thousand-Year Door)|Jerry]], [[Screamy]] and [[Torque (character)|Torque]]), who generally hated him and only traveled with him because Luigi owed them a debt, almost always secretly told Mario what really happened. Later, Luigi got interviewed and five [[Super Luigi (series)|Super Luigi]] books were sold. Luigi's adventure involved rescuing [[List of implied characters#Princess Eclair|Princess Eclair]] of the [[List of implied locations#Waffle Kingdom|Waffle Kingdom]] from the [[Goomboss|Chestnut King]]. Luigi's story sounded extremely similar to Mario's in most aspects. He usually messed up during his adventure, such as accidentally knocking his partner Blooey the [[Blooper]] into [[lava]].

Luigi also appears in the [[audience]] of Mario's battles, sometimes throwing helpful items to him. He also cheers Mario on during the final battle with the [[Shadow Queen]], shouting "<font color=green>YOU GO, BRO!</font>". [[List of implied organizations#Luigi Fan Club|His fan club]], whose members include [[Toadia]], a Toad from [[Poshley Heights]], was also given two mentions in the game. The "L Emblem" Badge changes Mario's color scheme to Luigi's when equipped. The character [[Pennington]] constantly mistakes Mario for Luigi until almost the very end of the game. Lastly, Luigi's silhouette is the first of the many white character silhouettes that walk across the screen during the game's ending credits, continuing Luigi's past RPG roles as a parade leader.
;Tattles
''Who's this guy? ...Come on, you really need to ask me that? Gimme a break! That's your brother, Luigi! But...I wonder why he's here? I'm sure he'll tell you if you ask him.''

''That's your brother, Loobie... Wait, no! I mean, uh...Loofa... No, I mean Luigi! If you wonder what Luigi's up to, I'm sure he'd tell you. All you gotta do is ask! In fact, it kinda looks like he's dying to tell you stuff, so you oughta rap with him!''

''I'm sure you know this, but that's your brother, Luigi. Duh. It seems like he's suspenders-deep in his own crazy adventure right now. If you ask him, he'll tell you all about it...but I wonder how much of his story is true...''

''That's your brother, Loozie... Wait, no! I mean, uh...Big Lou... No, I mean Luigi! If you wonder what Luigi's up to, I'm sure he'd tell you. All you gotta do is ask! In fact, it kinda looks like he's dying to tell you stuff, so you oughta rap with him!''

====''Super Paper Mario''====
[[File:Luigi SPM artwork.jpg|left|thumb|upright=0.9|Luigi's appearance in ''Super Paper Mario'']]
{{see also|Mr. L}}
In the game ''[[Super Paper Mario]]'', Luigi plays a very large role, much bigger than he did in the previous ''Paper Mario'' games; in fact, a considerable part of the entire story of the game depends on him (as the man in green of both prophecies, he must decide which one of them, the [[Light Prognosticus|light]] or the [[Dark Prognosticus|dark]], to trigger). He is noticeably as brave as Mario here, rushing in to save Princess Peach, jumping on Bowser, and calling [[Count Bleck]] a "goon". He is a playable character for the first time in the series, and the last character to join Mario's party. His special move is the [[Super jump (Super Paper Mario)|super jump]], which has him fold up then launch into the air; he also has a somewhat higher regular jump and slightly lower traction than his brother.

At the beginning of the game, Mario and Luigi head to Bowser's Castle once they learn Peach has been kidnapped again. Luigi is then sucked into a vortex along with Bowser and his minions by Count Bleck. Luigi then wakes up during Peach and Bowser's forced marriage and attempts to stop the wedding, but fails. He is then rendered unconscious until the end of Chapter 2, where a pair of Goombas witness his awakening. Luigi wishes to try and save the Princess again, but the Goombas convince him to help them escape. They head off but are stopped by a dead end. As they try to think of what to do next, [[Nastasia]] appears and hypnotizes one of the Goombas. Trapped by her and a group of Koopa Troop-turned-Bleck minions, the other Goomba simply surrenders to her and willingly joins Bleck's forces. Nastasia then orders the minions to hold Luigi in place as she brainwashes him. It is due to this that Luigi became [[Mr. L]], also known as "The Green Thunder".

Before Mario could get his hands on the fifth [[Pure Heart]], Mr. L makes an appearance in the [[Whoa Zone]], Mario and his team do not recognize that Mr. L is actually Luigi. Mr. L returns again as a boss during Chapter 6, after [[Sammer's Kingdom]] is destroyed. After being defeated, [[Dimentio]] betrays him and sends Mr. L to [[The Underwhere]]. He lost all memory of his having been Mr. L and returned to his normal state. Mario finds Luigi scared in The Underwhere (Chapter 7), and the two soon regrouped with the other playable characters ([[Bowser]] and [[Princess Peach]]) as well.

Eventually, Luigi faced [[Dimentio]] in [[Castle Bleck]] alone, without a single [[Pixl]] by his side. After defeating Dimentio, Luigi gets knocked out by Dimentio's fake suicidal attack. Peach later finds and awakens him, and they and Bowser later rejoined Mario, and their combined strength allowed them to defeat Count Bleck. However, Dimentio then snatched the [[Chaos Heart]] from him and activated a mind-controlling [[Floro Sprout]] he had planted on Luigi much earlier, turning his mind back into Mr. L. After explaining that the prophetic [[Dark Prognosticus]] stated that Luigi was the ideal host for the Chaos Heart, [[Dimentio]] merged himself and Luigi with the Chaos Heart, becoming [[Super Dimentio]]. After defeating Super Dimentio, Luigi returns to normal, and they all witness [[Count Bleck]] and [[Tippi]] using their love to stop [[The Void]].

====''Paper Mario: Sticker Star''====
[[File:LuigiPMSS.gif|thumb|Luigi in ''[[Paper Mario: Sticker Star]]'']]
Luigi makes another appearance in ''[[Paper Mario: Sticker Star]]''. Here, he can be seen in the backgrounds and scenery within five areas:
*W1-6: [[Goomba Fortress]] - While Mario crosses the bridge to the tower, Luigi is seen sitting on the wall in the background.
*W2-5: [[Drybake Stadium]] - When Mario reaches the fourth floor, if he takes the exit on the left, Luigi is sitting near a window on the right.
*W3-12: [[Whitecap Beach]] - As Mario walks along the pier, Luigi can be seen sitting on the rock on the right. 
*W4-5: [[Whiteout Valley]] - Near the end of the ski ride, Luigi is seen sitting on one of the ski lifts going downhill. 
*W5-5: [[Rugged Road]] - After the [[Save Block]], Mario reaches an area with volcanic rocks falling from the sky, creating holes in the ground. Causing one rock to make a hole below a ledge lets Mario reach the underground. Heading north to a hot spring, Luigi is seen in another spring in the background.
The player can [[Paperize]] the environment to pull Luigi out, who appears in a small size. Luigi then jumps out of the scenery and leave. Upon finding Luigi in the five areas, he can be seen leading the parade at the credits (replacing the [[Green Toad]]), much like in ''Super Mario RPG'', ''Paper Mario'', and ''Paper Mario: The Thousand-Year Door''. In [[Shy Guy Jungle]], if the player keeps digging through the pile of paper, they may find a piece of paper that says a "mysterious green guy" was spotted at [[Goomba Fortress]]. The player can also read articles about Luigi's various appearances in the northernmost house in the east section of [[Decalburg]]. ''Sticker Star'' is notable for being the only game in the ''Paper Mario'' series where Luigi had no lines of dialogue.

====''Paper Mario: Color Splash''====
[[File:PMCS Luigi kart.png|thumb|Luigi in ''[[Paper Mario: Color Splash]]'']]
Luigi reappears in ''[[Paper Mario: Color Splash]]''. Like in ''Paper Mario: Sticker Star'', Luigi can be found in various places throughout [[Prism Island]], which usually requires Mario to use the [[Cutout]] ability to find him. He can be found in the following six areas:
*[[Bloo Bay Beach]]: Located in an outdoor shower room behind the juice bar.
*[[Marmalade Valley]]: Located near the Save Block found on the second level of the excavations area is an "L" carved into an inaccessible corner.
*[[The Golden Coliseum]]: Located on top of one of the spectator stands while Mario is in the arena.
*[[Plum Park]]: Located in the tree found in the area where Birdo is encountered.
*[[Redpepper Crater]]: Located in a waterfall within the hot springs area.
*[[Green Energy Plant]]: A sideways "L" can be found on a monitor outside on the far right near the Green Toad House.
Additionally, Luigi plays a role in the story, where he helps [[Mario]] and [[Huey]] reach [[Bowser's Castle|Black Bowser's Castle]] with his [[Standard Kart]] once all the [[Big Paint Star]]s have been found, as well as helping Mario and Peach escape said castle. Unlike ''Sticker Star'', Luigi has dialogue this time around. If he is found in all of the six locations, he once again can be seen leading the ending parade while on his kart.

====''Paper Mario: The Origami King''====
[[File:PMTOK Luigi.png|150px|thumb|Luigi in ''Paper Mario: The Origami King'']]
{{quote|Oh! That's right! I was gonna go look for the key to Peach's Castle. We got locked in, remember? Mario's always saving me...so I just wanted to do something nice for him for a change. I'm really happy to see my hat again...but I've still gotta find that key. Let's-a go!|Luigi|Paper Mario: The Origami King}}
Luigi reappears in ''[[Paper Mario: The Origami King]]'', where he can be seen driving a Standard Kart, similarly to his appearance in ''Paper Mario: Color Splash''. In the beginning, he and Mario are invited into Toad Town to celebrate the Origami Festival. Upon noticing that the town is deserted, the two head to Peach's Castle. However, they are immediately locked inside, and Luigi goes off to find the key to the front door. After King Olly relocates Peach's Castle, Mario glimpses Luigi's hat left behind in the rubble. After traversing through the Whispering Woods and Graffiti Underground, Mario and Olivia locate Luigi in the castle ruins trapped in a wall. After being freed with the 1,000 Fold Arms, Luigi sets off to find the [[key to Peach's Castle]]. 

Mario and Olivia later find Luigi in the maintenance room of the [[Ninja Attraction]], trapped in several gears. After freeing him, Luigi claims he found the key to Peach's Castle and hands it to Mario, although this key is actually the [[Shogun Studios Master Key|master key]] of [[Shogun Studios]], which Mario is coincidentally looking for.

In [[Shroom City (Paper Mario: The Origami King)|Snif City]], Luigi loses the mood-guessing game and gets trapped in the giant lamp above the game's stall (adorning it with a green "L" in the process). When Mario comes along, he wins the game and frees Luigi from the lamp. Once again, Luigi claims to have the key to Peach's Castle, which turns out to be the [[Suite Key|key to the suite]] of the town hotel, but happens to be the key Mario needs at this point.

Luigi is next seen in the backyard of the house on [[Mushroom Island]], having swum all the way there. Mario finds a note from him on [[Full Moon Island]], which directs him here. This time, Luigi has the [[Diamond Key|key]] needed to access [[Diamond Island]]. Although Luigi is embarrassed over constantly finding the wrong keys, Olivia assures him that all the keys he has been finding have still been very helpful. Determined to find the right key, Luigi sets off once more, but not before accompanying the others to the basement and learning about King Olly's backstory through the [[Origami Craftsman]].

In [[Bowser's Castle]], Luigi is found in Kamek's room and is positive he has the key to Peach's Castle this time, which is instead the [[Key to Bowser's Castle|key to the throne room]] of Bowser's Castle.

After Mario, Olivia, and Bowser reach the front door of Peach's Castle, Luigi reaches them using a glider on his kart. Luigi initially apologizes for failing to find the key, although Olivia reassures him that via his screwups, he has overall succeeded in helping them with their quest. What's more, it turns out the key has been in the back of Luigi's kart the whole time. Luigi accompanies Mario's party inside, although he falls down the trapdoor in the castle foyer while attempting to save Origami Peach.

Luigi later arrives in the throne room of [[Origami Castle]] after [[King Olly]]'s defeat, bringing the Origami Craftsman with him who helps Olivia fold King Olly's body into the 1000th crane, which Olivia uses to make a wish to undo all of King Olly's actions. Luigi is ecstatic to see Princess Peach back to her normal self, although he wonders why Olivia is no longer with them.

During the Origami Festival at the end of the game, Luigi can be seen sitting in the [[Boot Car]] and conversing with its owner, before he joins the others to release paper lanterns in order to honor Olly and Olivia. Following the festivities, he and Mario drive home as the credits roll.

===''Luigi's Mansion'' series===
====''Luigi's Mansion''====
[[File:LM Luigi Flee.png|thumb|175px|Luigi in ''Luigi's Mansion'']]
For the first time since ''[[Mario is Missing!]]'' and ''[[Luigi's Hammer Toss]]'', Luigi gets his own solo adventure in ''[[Luigi's Mansion]]''. Before the events of the game, Luigi wins [[Luigi's Mansion (location)|a mansion]] in a contest he hadn't even entered. Overjoyed, Luigi tells Mario to go ahead and meet up with him there. Luigi walks through a gloomy, haunted forest that leads to a big haunted house. The mansion is actually the one Luigi is looking for and he gets nervous. Upon arriving, Mario is nowhere to be found. While searching for his brother, Luigi meets [[Professor Elvin Gadd]] who proceeds to tell him that the mansion is haunted and that Mario was taken captive. Handing Luigi his [[Poltergust 3000]], a vacuum that can capture [[Ghost (Luigi's Mansion series)|ghosts]], Luigi sets out to find and rescue Mario. He captures all the portrait ghosts, the 50 Boos, and the game's main antagonist, King Boo, whom he has to fight with Bowser. Luigi defeats King Boo, gives the remaining portrait ghosts to E. Gadd, rescues Mario, and cries tears of joy.

Luigi's cowardice is more prominent in this game than most others; every time a ghost appears nearby or something makes a loud noise, Luigi gets startled, making him jump slightly into the air and preventing him from moving for a short time. Luigi also has a [[Health Meter]] that depletes whenever he takes damage, and if it reaches 0, Luigi [[Game Over|dies]]. Unlike most other ''Super Mario'' games, Luigi cannot jump with a button command, which limits his movement. However, Luigi can use the Poltergust 3000 to suck in ghosts after stunning them with his [[flashlight]] and shoot out [[element medal|fire, ice, and water]] blasts. Luigi reappears as the main protagonist in the Nintendo 3DS remake of ''Luigi's Mansion'', though he now receives a slime-themed counterpart in [[Gooigi]], who appears in the remake's co-op mode.

====''Luigi's Mansion: Dark Moon''====
[[File:Luigi entering the Gloomy Manor.png|thumb|left|Luigi enters the Gloomy Manor.]]
In the sequel to ''Luigi's Mansion'', ''[[Luigi's Mansion: Dark Moon]]'', Professor E. Gadd calls for Luigi's help from [[Evershade Valley]] and transports him over there with E Gadd's [[Pixelator]]. Once there, Luigi is told the [[Dark Moon]] has shattered and that the valley's normally friendly ghosts have become mischievous and hostile. E. Gadd then sends Luigi to the first mansion, [[Gloomy Manor]], to retrieve the improved version of the Poltergust 3000, called the [[Poltergust 5000]], and to see what he can find out. In the process, Luigi catches ghosts, including the powerful [[Poltergeist]], with the Poltergust 5000. He later enters the manor's [[Cellar (Luigi's Mansion: Dark Moon)|cellar]], where the [[Grouchy Possessor]] takes control of a massive spider and attacks Luigi. Luigi manages to catch this ghost, return the spider to normal, and recover the first Dark Moon piece. He is subsequently transported back to E. Gadd's lab.

Luigi's next destination is the [[Haunted Towers]], which were revealed due to the collection of the Dark Moon piece. Here, Luigi catches more ghosts (such as [[The Three Sisters]]) and rescues one of E. Gadd's Toad assistants. In addition, he encounters [[Polterpup]] for the first time, but when Luigi captures this ghost, he escapes. Luigi eventually encounters a staircase being controlled by the [[Harsh Possessor]]. He catches this ghost, returns the staircase to normal, and recovers the second Dark Moon piece. He is then returned to E. Gadd's lab.

Next, Luigi goes to the [[Old Clockworks]]. Here, he catches more ghosts (including the [[Ancient Poltergeist]]) and rescues another Toad assistant. He also finds Polterpup and catches the ghost again, but he again escapes. After recovering the clock hands (that were stolen by a group of [[Greenie]]s), Luigi goes to the top of the tower and locates the [[Overset Possessor]]. The possessor controls the clock on the tower to attack Luigi but is caught. Luigi then recovers the third Dark Moon piece and returns to the lab again.

Luigi then goes to [[Secret Mine]]. Here, it is discovered that certain ghosts are being powered up in the mine. Regardless, Luigi catches them and finds the [[Shrewd Possessor]], who controls a pool of ice. This ghost is also caught, and Luigi recovers the fourth Dark Moon piece.

E. Gadd then tells Luigi that the final Dark Moon piece is in the [[Treacherous Mansion]], although he warns that his [[List of implied items#Parascope|Parascope]] is picking up extremely high paranormal signals from the area (which frightens Luigi) before sending Luigi there through the Pixelator with the mansion key. Just as Luigi goes to unlock the mansion's front door, the key is stolen by Polterpup. Luigi chases the ghostly dog and retrieves the key, finally catching Polterpup in the process. After entering the mansion, Luigi catches more ghosts (including the [[Strong Poltergeist]]) and rescues more Toad assistants. A photo received from one of the assistants reveals that King Boo and his Boo minions have trapped Mario in a painting (much like in the first ''Luigi's Mansion''). Recognizing the location in the picture as the [[Train Exhibit]] in the Treacherous Mansion, E. Gadd sends Luigi there to rescue Mario. However, Luigi and E. Gadd soon discover that it was a trap, and Luigi is ambushed by [[Big Boo]]; a large Boo made up of many smaller Boos (who Luigi subsequently captures). Back at the lab, Luigi and E. Gadd ponder where King Boo and the painting are. Soon after, the Parascope picks up strong readings from the Treacherous Mansion's [[Terrace (Luigi's Mansion: Dark Moon)|terrace]]. Luigi is sent there, where King Boo appears and opens the [[paranormal portal]], which releases a large number of ghosts into the mansion, then escapes with the Mario painting [[??? (Luigi's Mansion: Dark Moon)|inside]]. E. Gadd tells Luigi to capture the ghosts in the mansion, as the paranormal activity is so strong that their dimension could collapse upon itself. Luigi does this then enters the Paranormal Portal, arriving in King Boo's Illusion.

In the portal, Luigi finds the final [[Possessor]] ghost, the [[Tough Possessor]], who clones himself and controls multiple suits of armor. The final Possessor is caught, and Luigi finds the final Dark Moon piece. E. Gadd attempts to transport Luigi back to the lab. However, King Boo interrupts and sends Luigi into [[King Boo's Illusion|an illusion]]. Here, Luigi and King Boo fight. Before the fight, King Boo reveals that he was the one who shattered the Dark Moon and captured Mario. Luigi is ultimately victorious, catching King Boo, taking his crown, and rescuing Mario with the [[Dark-Light Device]]. Luigi, Mario, and E. Gadd rejoice, and a Greenie takes a photo with them and the now once again friendly ghosts (due to the restored Dark Moon). Luigi then takes in Polterpup as his pet, and Polterpup is later seen sleeping on Luigi, with Luigi seemingly overcoming his fear of ghosts.

Luigi's controls and personality are mostly retained from the previous game. Luigi still can't jump, but he isn't as easily frightened from ghosts, being able to still move around while being startled. Luigi's Health Meter also returns, functioning the same way as it did in the original game, though players can recover from a Game Over if they have found a [[Gold Bone]]. While the Poltergust 5000 can't shoot out elemental blasts, Luigi can still use it to suck up ghosts and objects, cause a [[Strobulb|wider and stronger beam of light]], and reveal [[Dark-Light Device|hidden objects]]. 
{{br}}

====''Luigi's Mansion 3''====
Luigi appears as the main protagonist in ''[[Luigi's Mansion 3]]''. He has a new Poltergust that can fire plungers and lift him off the ground, along with using the Strobulb and Dark-Light attachments, as well as storing Gooigi.

[[File:LM3 Luigi wakes up.jpg|thumb|left|Luigi waking up to Princess Peach's scream]]
In this game, Luigi was invited to stay at [[The Last Resort]] hotel and brings Mario, Princess Peach, three Toads, and Polterpup. However, that night the hotel turns haunted and it is revealed that the invitation was set up by [[Hellen Gravely]] so that King Boo could trap Luigi and his friends in paintings. Just as King Boo was about to trap Luigi, he manages to escape through a laundry chute.

Luigi ends up in the basement where he finds the [[Poltergust G-00]] in a car. He later finds Professor E. Gadd trapped in a painting on the second floor, and after releasing him with the Dark-Light Device, E. Gadd aids Luigi once more by providing him with the [[Virtual Boo]] for communication, and [[Gooigi]].

[[File:LM3 Luigi and Mario hug.jpg|thumb|Luigi hugging Mario after rescuing him]]
To advance through the hotel, Luigi must retrieve the missing elevator buttons from the ghostly hotel staff, freeing the three Toads along the way. Once Luigi reaches the top and defeats Hellen Gravely, he rescues Mario, who leads him to the rooftop where Peach is. After releasing Peach, however, King Boo traps everyone besides Luigi, who was saved by Polterpup, in a single painting. King Boo, enraged that he missed Luigi, engages him in battle.

After Luigi defeats King Boo, the entire hotel collapses from taking the bulk of the battle. Polterpup saves Luigi once again and frees everyone from the painting. During the credits, Luigi helps rebuild the hotel with the newly-turned friendly ghosts, and after construction was complete, departs with Mario, Peach, Polterpup, and the Toads.

===''Mario & Luigi'' series===
Luigi appears as one of the titular characters in the ''[[Mario & Luigi (series)|Mario & Luigi]]'' series, alongside his brother, [[Mario]]. Luigi is often forced into adventures alongside Mario through comical means ([[Bowser]] mistaking him as a new recruit in ''[[Mario & Luigi: Superstar Saga]]'', being pushed into a time hole in ''[[Mario & Luigi: Partners in Time]]'') and is shown to be reluctant in various activities within the adventures, but still follows Mario's lead regardless. In some scenarios, he has even been forced to venture off on his own in order to save Mario (in ''Mario & Luigi: Superstar Saga'' he must go to [[Guffawha Ruins]] to retrieve [[Crabbie Grass]] to cure Mario of his bean fever and in ''[[Mario & Luigi: Bowser's Inside Story]]'' where he must rescue Mario from a [[Sockop]]). In battle, Luigi usually boasts a high [[Heart Point|HP]] stat along with a decently high [[defense]] stat, making him a decent supporting character. Compared to Mario, Luigi has a lower [[speed]] stat and slightly lower [[power]] stat.
====''Mario & Luigi: Superstar Saga'' / ''Mario & Luigi: Superstar Saga + Bowser's Minions''====
[[File:LuigiSSS.png|thumb|upright=0.55|180x180px|left|Luigi in ''Mario & Luigi: Superstar Saga'']]
[[File:MLSS+BM Artwork - Luigi.png|thumb|180x180px|Luigi in ''Mario & Luigi: Superstar Saga + Bowser's Minions'']]
In ''[[Mario & Luigi: Superstar Saga]]'' and its [[Mario & Luigi: Superstar Saga + Bowser's Minions|remake]], Luigi joins Mario on his adventure. Though he originally didn't intend to go, [[Bowser]] scooped him up and brought him along in the [[Koopa Cruiser]] and they headed off to the [[Beanbean Kingdom]]. Luigi's personality shines through during this adventure, as he is often reluctant to do anything dangerous. One such time is when Mario comes down with the [[Bean Fever]] and Luigi must go to [[Guffawha Ruins]] to find the [[Crabbie Grass|cure]], though hearing of the dangers, he becomes too scared to move properly, disabling his [[Jump]] command for the time being. He also briefly poses as Princess Peach via [[Peach's Extra Dress]] in an attempt to rescue her, successfully tricking [[Fawful]] and [[Bowletta]] into releasing Peach and abducting him. However, he is ultimately forced to reveal his true identity when Bowletta, suspicious about "Peach" covering "her" mouth, tricks "her" into turning around by claiming a giant cockroach was behind "her", although he does ultimately retrieve the actual Beanstar from Bowletta.

Luigi's actions and attributes differ from Mario's as well. For example, Luigi has higher HP, but lower attack power than Mario. While both he and Mario can Jump and use [[Hammer]]s, the actions they perform depend on their positioning. Luigi can learn the [[High Jump]], which has him jump on to Mario to jump higher, and he can also turn Mario into [[Mini-Mario]] by hitting him with his hammer, both are performed if Luigi is in the back. Additionally, Luigi can [[Dunk Hammer|burrow]] into the ground if he is hit with Mario's hammer if Mario is in the back. Later in the game, the bros. learn special hand techniques; in Luigi's case, the [[Thunderhand]], which has him create a ball of electric energy in front of him that can power [[Conductor]]s. If used on Mario while Luigi is in the back, he stuns him, [[Tickle|allowing them to move in sync while facing in one direction]].

While Luigi can use his standard techniques in battle, Luigi has different [[Bros. Attack]]s than Mario as well. [[Bounce Bros.]], [[Knockback Bros.]], and [[Thunder Bros.]] are taught to Luigi at the same time as when Mario learns his variants, with [[Cyclone Bros.]] being a hidden skill obtained when winning the [[Secret Scroll 2]] in a minigame located the Hammerhead Bros.' cave after gaining the [[Ultra Hammer]].

====''Mario & Luigi: Partners in Time''====
{{see also|Baby Luigi}}
[[File:Luigi & Baby Luigi PiT.png|thumb|180x180px|[[Luigi]], with his younger self [[Baby Luigi]]]]
In ''[[Mario & Luigi: Partners in Time]]'', Mario and Luigi travel through time between the past and the present. While in the present, Luigi meets his infant self, [[Baby Luigi]]. The two team up with Mario and his [[Baby Mario|baby self]] in order to find [[Princess Peach]], who has been kidnapped by the [[Shroob]]s. Luigi's cowardly personality is still apparent, with his younger self seemingly having more courage than him. When talking to the [[Star Temple gate]] and completing the quest given, it is shown that Luigi has a very large heart and cares deeply for his brother and friends.

[[File:luigi&babyluigi.png|left|frame]]
While Luigi retains his Jump ability, the Hammer commands are given the younger versions of the bros. Luigi also does not have his High Jump, but instead gains Mario's move from the last game, the [[Spin Jump]], which allows him and Mario to float across large gaps. Later, he and Mario learn the [[Bros. Ball]] technique, which has him and Mario curl into a ball and allows them to move faster.

====''Mario & Luigi: Bowser's Inside Story'' / ''Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey''====
[[File:LuigiBIS.png|thumb|180x180px|left|Luigi in ''Mario & Luigi: Bowser's Inside Story'']]
At the start of ''[[Mario & Luigi: Bowser's Inside Story]]'', the Bros. go to an emergency meeting in [[Peach's Castle]], warning about the dangerous disease plaguing the [[Mushroom Kingdom]], called the [[blorbs]]. Mario and Luigi arrived in the castle so hastily that Luigi was first shown hopping on one foot while trying to put on his overalls, causing him to trip and fall face-first on the floor. During the meeting, Luigi ends up falling asleep, causing him to miss the fight between Mario and Bowser. Once Luigi is inhaled into Bowser's body due to the [[Vacuum Mushroom]], he lands in the [[Trash Pit]] and has to be rescued by Mario. Afterward, he joins his brother on the adventure. At one point during the adventure, however, Mario is separated from Luigi by a gang of [[Sockop]]s, forcing Luigi to rescue him alone.

While Mario and Luigi's controls are relatively the same, Luigi has additional commands. On the field, Luigi can once again turn Mario into [[Mini-Mario]] by hitting Mario with Luigi's hammer. Luigi joins in on Mario's Spin Jump, though Luigi can activate [[Drill Bros.]], which burrows the brothers into the ground, allowing them to dig under gates or uproot items such as [[Bean]]s.

Luigi also has his own set of [[Badge]]s, which boosts the effect of Mario's corresponding badge.

In the [[Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey|3DS remake]], Luigi makes a brief appearance in the new ''Bowser Jr.'s Journey'' mode, where he and Mario pass by Bowser Jr. who picks a fight with them. Starlow stops them from fighting, however, reminding them that there is no time for this, even for Bowser Jr. In the story timeline, this event happens while searching for the Star Cures.

====''Mario & Luigi: Dream Team''====
[[File:Luigi - Mario & Luigi Dream Team.png|thumb|upright=0.8|180x180px|Luigi in ''Mario & Luigi: Dream Team'']]
{{see also|Dreamy Luigi}}
Luigi makes an appearance in ''[[Mario & Luigi: Dream Team]]'', the fourth installment of the ''Mario & Luigi'' series. Due to the game being released during the [[Year of Luigi]], Luigi's role is far greater than the previous entries in the series. Luigi's appearance has also been updated from the previous three entries, as his overalls now fit properly, hiding his striped socks, and the L on his cap is green, like the M on Mario's is red, to match his appearance from the main games. 

When in the Real World, Luigi can use his hammer to turn Mario into Mini-Mario once again, though only on hard surfaces like rock or metal. If on soft surfaces, such as dirt or sand, the move becomes [[Mole Mario]] instead, which pounds Mario into the ground. He also learns the [[Side Drill]], which sends Mario and Luigi spinning in the direction they are facing like a drill, breaking certain blocks and obstacles. Finally, he and Mario can use [[Ball Hop]], which allows them to jump higher and reach previously inaccessible areas, which is an apparent combination of the High Jump and Bros. Ball from the first two ''Mario & Luigi'' games.

Luigi's biggest role in this game is opening portals to the Dream World whenever he sleeps on a [[Pi'illo]], which Mario jumps into and [[Dreamy Luigi]], a dream variant of Luigi, assists him while in the Dream World. Mario is unable to open Dream World portals, however, as shown early in the game. According to [[Prince Dreambert]], this is because Luigi's {{wp|Rapid eye movement sleep|REM}} wavelength is in the same range as that of a typical Pi'illo.

One of the main elements in the Dream World is the [[Mario & Luigi: Dream Team#Luiginary Works|Luiginary Works]], which has Dreamy Luigi transform into various different things by interacting with the objects around him and are activated by Starlow doing certain things to the sleeping Luigi's face. However, certain transformations are limited to specific areas. A type of Luiginary Work, called the [[Luiginoid Formation]], involves [[Luiginoid]]s created from the stars of a constellation that can be stacked, and will instantly defeat enemies that come into contact without battling them, and will even permanently remove them from the overworld. One such transformation has the [[Luiginoid]]s turn into a [[Giant Luigi|giant]], much like how [[Super Bowser|Bowser turned into a giant]] in the previous game. During battles, Dreamy Luigi will merge with Mario, raising his stats, and assist him with basic attacks along with allowing him to use Luiginary Attacks; the Dream World's variant of Special Attacks.

Both versions of Luigi also have their own special attacks, with the "real" Luigi having different [[Bros. Attack]]s than Mario, and Dreamy Luigi having [[Mario & Luigi: Dream Team#Luiginary Attacks|Luiginary Attacks]] that involve the Luiginoids.

====''Mario & Luigi: Paper Jam''====
[[File:Luigi - MarioLuigi-PaperJam.png|thumb|140px|left|Luigi in ''Mario & Luigi: Paper Jam'']]
For the first time in the series, Luigi starts off the adventure in ''[[Mario & Luigi: Paper Jam]]''. He and a [[Toad (species)|Toad]] enter the attic of [[Peach's Castle]]. Through a series of events involving a [[Scaredy Rat]], Luigi knocks over a [[Paper Mario book|book]] that contains the characters from the [[Paper Mario (series)|''Paper Mario'']] series. Upon landing, the book opens, releasing the characters from that world into the world of the ''Mario & Luigi'' series. Luigi soon meets up with Mario and [[Paper Mario (character)|the paper version of Mario]] to help put things back together.

Luigi controls much like how he does in the previous ''Mario & Luigi'' games. He gains additional Bros. Attacks and assists in the [[Trio Attack]]s, but overall Luigi is not much different from the other games. He does, however, have a [[Papercraft]] based on him called [[Papercraft Luigi]], which allows the player to use the Flying Hammer Attack that can damage spiked enemies. Additionally, several [[Battle Card (Mario & Luigi: Paper Jam)|Battle Card]]s have artworks of Luigi from previous games.

During the second visit to [[Gloomy Woods]], Mario and Paper Mario are both captured by King Boo, and Luigi must rescue them alone, similar to the ''Luigi's Mansion'' series.

A [[Paper Luigi|paper variant of Luigi]] is seen sleeping next to a gramophone when the player is viewing the [[Music Player]].

===''WarioWare'' series===
[[File:Super Mario Bros. 3-Lift.png|thumb|upright=1.1|Luigi's appearance in [[Super Mario Bros. 3 (lift microgame)|Super Mario Bros. 3-Lift]] in ''WarioWare: Twisted!'']]
Luigi rarely appears in the ''[[WarioWare (series)|WarioWare]]'' series. In ''[[WarioWare: Twisted!]]'', Luigi appears alongside his brother in [[Super Mario Bros. 3 (lift microgame)|Super Mario Bros. 3-Lift]], where he appears on the Level 3 variant of the minigame and he (along with Mario) must dodge incoming enemies. He also appears in [[Mario Brothers (WarioWare: Twisted!)|Mario Brothers]], again during the Level 3 variant, where he and Mario try to kick the enemy before the player can flip it back up-right.

In ''[[WarioWare: Touched!]]'', Luigi appears alone in the third level of the microgame [[Spin a Yarn]]. On the 3rd level difficulty, the player can unravel a Luigi making an "L" formation.

In ''[[WarioWare: Smooth Moves]]'', Luigi is one of the main instrumentalists who plays the violin in [[9-Volt]]'s microgame, [[Opening Night]].

In ''[[WarioWare Gold]]'', Luigi appears in the [[Mario Bros. (WarioWare Gold)|Mario Bros.]] microgame, and also reprises his role in Super Mario Bros. 3-Lift, now known simply as "Super Mario Bros. 3."

In ''[[WarioWare: Get It Together!]]'', Luigi appears with his [[Poltergust 3000]] in the [[Luigi's Mansion (microgame)|Luigi's Mansion]] microgame and shines his flashlight on the ghost after the player clears the microgame.

===''NBA Street V3''===
Luigi, along with Mario and Princess Peach, as a result of the Nintendo and {{wp|EA Canada|EA}} partnership, makes a fully playable guest appearance exclusive to the Nintendo Gamecube version of ''[[NBA Street V3]]''. The three are part of a team entitled "Nintendo All-Stars", alongside other all-star basketball teams. Luigi's team additionally has a special basketball court.

===''SSX on Tour''===
Luigi, Mario, and Peach, as with ''NBA Street V3'', make another playable guest appearance in the Nintendo GameCube version of ''[[SSX on Tour]]'', stemming from the same partnership with Nintendo and EA. In ''SSX on Tour'', Luigi snowboards in a mountain and performs various stunts to earn points.

===''Dance Dance Revolution: Mario Mix''===
In ''[[Dance Dance Revolution: Mario Mix]]'', Luigi is one of the characters (with the other being Mario) that can be chosen at the start of the single-player adventure. Aside from the cap at the starting house changing from Mario's to Luigi's, nothing in the adventure is changed. Luigi travels with [[Toad]] to recover the stolen [[Music Key]]s in Mario's place.

Luigi also appears as the second player during the two-player Dance-Off mode.

===''Mario Baseball'' series===
====''Mario Superstar Baseball''====
In ''[[Mario Superstar Baseball]]'', Luigi serves as the vice captain of [[Mario]]'s team. His team names are the ''Luigi Gentlemen'', ''Luigi Vacuums'', ''Luigi Mansioneers'', and ''Luigi Leapers''. Luigi has similar stats and abilities to Mario, but Luigi can perform a [[Super Jump (Mario Baseball series)|Super Jump]] on the field while Mario cannot, and his Star Pitch is the [[Green Fireball]]. Luigi's stats are well balanced, although his batting skills are slightly weaker than his other skills.

During the opening cinematic, Luigi is seen practicing with Mario at Mario Stadium until a flyer depicting Bowser arrives. Later in the scene, Luigi is seen running for a fly ball hit by Donkey Kong, where Luigi makes a leap from the center field wall to catch the ball for the second out of the inning. After Mario hits a walk-off home run, Luigi and others storm the field to celebrate. In the closing cinematic, which plays after defeating Bowser's team in Challenge Mode via Special Cup, Luigi is one of a few characters at the baseball field. When Bowser arrives, Luigi serves as the catcher, waiting for Mario's first pitch.

====''Mario Super Sluggers''====
[[File:Luigi MSS.jpg|thumb|left|upright=1.1|Luigi in ''[[Mario Super Sluggers]]'']]
In ''[[Mario Super Sluggers]]'', Luigi is a team captain, leading his team called the ''Luigi Knights''. Luigi, along with [[Bowser Jr.]] and [[Princess Daisy|Daisy]], are the only secondary team captains to have a home stadium, with Luigi's being [[Luigi's Mansion (location)|Luigi's Mansion]]. Compared to the predecessor, Luigi's batting, fielding, and running have been improved slightly, while his pitching skills remained the same. He gained the Star Swing [[Tornado Swing]] along with a new Star Pitch called the [[Tornado Ball]] to differentiate him from his brother. In challenge mode, Luigi is the first player that joined the team. Luigi's ''Mario Super Sluggers'' baseball card listed his Rookie Year as 1982, although ''Mario Bros.'', the game that he first appeared in, was released in 1983.

During the opening cinematic, Luigi along with Mario, Daisy, Yoshi, Red Toad, and Birdo ride a yacht en route to the Baseball Kingdom. Upon arrival, they view the island from the summit of a lighthouse. After arriving at Mario Stadium, Luigi brandishes a Wii Remote that transforms into a baseball bat, a similar technique that Daisy performed moments before. Later in the scene, Luigi catches the ball that was passed from his teammates, but Donkey Kong performs a body check on Luigi, sending him spiraling towards the wall. Daisy panics and the audience silences, but Luigi is able to hold on to the ball long enough to get the final out, where everyone else joins the frame to celebrate. In the cinematic after defeating Bowser's team in Challenge Mode, Luigi is seen celebrating with the other characters in the middle of the infield. Afterwards, Luigi and the rest of the crew march towards the entrance of the Baseball Kingdom to gaze upon the sunset before the lights come on for the night.

===''Super Princess Peach''===
[[File:SPP Luigi.png|thumb|upright=0.8|Luigi captured by a [[Hammer Bro]]]]
During the opening story of ''[[Super Princess Peach]]'', Mario, Luigi, and several [[Toad (species)|Toads]] were taken captive by Bowser and his minions, using the power of the [[Vibe Scepter]]. While Mario was guarded by Bowser himself, Luigi was given to a [[Giant Kamek]] to be guarded. Once [[Princess Peach]] defeats the Giant Kamek, Luigi (called "the green man") is rescued. Luigi does not appear again until Mario is rescued at the end of the game, where he is shoved to the side by Peach as she runs to Mario.

===''Mario Strikers'' series===
[[File:Luigi - Super Mario Strikers.png|thumb|left|125px|Artwork of Luigi in ''[[Super Mario Strikers]]'']]
Luigi is a team captain in ''[[Super Mario Strikers]]'' (also known as ''Mario Smash Football'' in the PAL regions). Luigi's number in ''Super Mario Strikers'' is 2, probably referring to him being Mario's "younger brother" and him usually filling the "Player 2" role in earlier titles. His emblem is a lightning bolt, an element he has been associated with since ''[[Mario & Luigi: Superstar Saga]]''. In the game, his Super Strike is the [[Super Strike#Luigi - Vicious Vortex|Vicious Vortex]].

Luigi returns as a team captain in the sequel to ''Super Mario Strikers'', ''[[Mario Strikers Charged]]'' (also known as ''Mario Strikers Charged Football'' in the PAL regions). He is now classified as a Balanced player alongside Mario, meaning his stats are well-rounded and he does not have any glaring strengths or weaknesses. Luigi's [[Super Ability]] is [[Super Luigi!]], which allows him to become giant and crush his opponents, opening scoring opportunities, and his [[Mega Strike]] is called [[Thunder Luigi]], which completely electrifies Luigi and the soccer ball.

Luigi is again playable in ''[[Mario Strikers: Battle League]]'', where his [[Hyper Strike]] is Spin Tornado. Here, he is a technique-type character with technique being his strongest statistic, while having weaker shooting.

===''Mario Hoops 3-on-3''===
Luigi appears in the game ''[[Mario Hoops 3-on-3]]'' as one of the starting playable characters and is an All-Around character. To use his [[Special Shot]], the [[Green Fire Shot]], the player has to tap out the letter "L" twice on the touch screen. Luigi's Baller name is the ''Mushroom Dynamite''.

===''Itadaki Street'' series===
Luigi appears as an unlockable character in ''[[Itadaki Street DS]]'', unlocked by playing through the Tour Mode of the game. He is a Rank C character when controlled by the computer. Several pieces of Luigi's clothing and gear also appear as unlockable customizations for the player's avatar character.

Luigi returns in the Wii follow-up to ''Itadaki Street DS'', ''[[Fortune Street]]'', this time as an initially playable character. Like in the last game, Luigi is a Rank C character when he is a computer-controlled character.

===''Mario & Sonic'' series===
====''Mario & Sonic at the Olympic Games''====
[[File:MaSatOG Luigi Shadow intro.jpg|thumb|200px|Luigi in the opening of the Wii version of ''Mario & Sonic at the Olympic Games'']]
Luigi is a playable character in both the [[Wii]] [[Mario & Sonic at the Olympic Games (Wii)|version]] and [[Nintendo DS]] [[Mario & Sonic at the Olympic Games (Nintendo DS)|version]] of ''Mario & Sonic at the Olympic Games'', where is categorized as an All-Around character with balanced statistics. He has the same stats as Mario, but he has less power and more speed compared to him. In the Wii version's opening, Luigi is seen at the start with all of the other athletes, as well as competing in the [[100m (Mario & Sonic at the Olympic Games for Wii)|100m]] and [[110m Hurdles (Mario & Sonic at the Olympic Games)|110m Hurdles]], the latter where he seems to have a rivalry with [[Shadow the Hedgehog]] that parallels the one between his brother and [[Sonic the Hedgehog]].

====''Mario & Sonic at the Olympic Winter Games''====
Luigi appears as an All-Around type playable character again in the Wii [[Mario & Sonic at the Olympic Winter Games (Wii)|version]] of ''Mario & Sonic at the Olympic Winter Games'', as well as a costume based on Luigi for Miis to wear being introduced. In the game's opening, Luigi appears at the start and end with all of the other athletes, and also competing in [[Halfpipe]] and [[Short Track 1,000m]]; in the latter event, Luigi and Shadow once again clash as they try to outpace each other only for newcomer [[Metal Sonic]] to outpace them and take the lead, putting Luigi in third place.

As well as being a playable character, Luigi also appears in the Adventure Tours mode of the Nintendo DS [[Mario & Sonic at the Olympic Winter Games (Nintendo DS)|version]], where he is first found in [[Frostown]] and asks Mario and Sonic to challenge him at [[Cross-Country]]. Upon being defeated, he joins their party and can be selected for [[Event]]s with free character selection. Once at [[Sparkleton]], Luigi helps Mario and [[Sonic the Hedgehog|Sonic]] look for a key to a gate. A [[Boo]] scares Luigi away, which makes Luigi run into a tree, causing the key to fall from it and Boo steals it. Angered at the Boo's insults, Luigi gives chase to the Boo and, if he gets the key in less than forty seconds, the Boo runs away. After the players clear the ice walls at [[Polastraits]], King Boo is angry that Luigi upset the Boos in Sparkleton, and Luigi is challenged to [[Alpine Skiing GS]]. After Luigi beats King Boo, King Boo flees.

====''Mario & Sonic at the London 2012 Olympic Games''====
[[File:M&SATLOG Luigi Relay artwork.png|thumb|200px|left|Artwork of Luigi for ''Mario & Sonic at the London 2012 Olympic Games'']]
Luigi returns as an All-Around class playable character in the Wii [[Mario & Sonic at the London 2012 Olympic Games (Wii)|version]] of ''Mario & Sonic at the London 2012 Olympic Games'', as well as the Mii costume based on him returning. In the game's opening, Luigi appears with the other athletes at the start as well as competing in [[Equestrian - Show Jumping]] and [[Dream Hurdles]], competing with Mario, Sonic, and [[Miles "Tails" Prower|Tails]] in the second event. Luigi also appears as a character that can be spoken to in London Party mode to play a minigame and earn stickers.

In the [[Nintendo 3DS]] [[Mario & Sonic at the London 2012 Olympic Games (Nintendo 3DS)|version]] of the game, Luigi is included in the Heroes group, alongside Mario, Sonic, and Tails, allowing him to only compete in certain [[Event]]s. In the Story Mode, Luigi first appears helping investigate the [[Phantasmal Fog]] in the [[Main Stadium]], and then helps clear it up before the three head off to [[Hyde Park]] to take a look at the fog there and check that Peach and the other female characters staying there are alright. After seeing that the Girls have cleared up the park, Luigi, Mario, and Toad head to the [[British Museum]], where they come across Sonic and [[Miles "Tails" Prower|Tails]] and the five of them clear the fog from the area. After finding out some information about the origin of the Phantasmal  Fog, Luigi leaves with [[Charmy Bee|Charmy]] to investigate the [[London Tennis Club]], where they find Waluigi challenging Metal Sonic. After Waluigi defeats Metal Sonic, Luigi and Charmy follow them to [[Eton Dorney]], meeting up with Mario and Toad, and after Waluigi and Wario defeat [[Dr. Eggman]] and Metal Sonic again, they head back to the Main Stadium. When the fog reappears, Luigi helps save [[Cream the Rabbit|Cream]] and [[Cheese (character)|Cheese]] from some [[imposter]]s, and then heads to [[Stonehenge]] with Mario, Toad, Sonic, Tails and [[E-123 Omega|Omega]], where they find the lid of the [[Fog urn]] and learn that Bowser and Dr. Eggman are hiding inside [[Big Ben]]. The Heroes head back to [[London]] and Luigi, Mario, Sonic and Tails defeat Bowser and Dr. Eggman and seal away the Phantasmal Fog, before returning to the Main Stadium for the opening ceremony of the Olympics. A [[List of badges in Mario & Sonic at the London 2012 Olympic Games (Nintendo 3DS)|badge]] of Luigi can be obtained from the Badge Machine.

In the Nintendo 3DS [[Mario & Sonic at the Rio 2016 Olympic Games (Nintendo 3DS)|version]], Luigi is only playable in [[Table Tennis (Mario & Sonic at the Rio 2016 Olympic Games for Nintendo 3DS)|Table Tennis]] and [[110m Hurdles (Mario & Sonic at the Rio 2016 Olympic Games)|110m Hurdles]]. Luigi also appears as a supporting character or a rival in the Road to Rio mode if the player joins Mario or Sonic's Gym respectively.

Luigi is also playable as a Balance-type character in ''[[Mario & Sonic at the Rio 2016 Olympic Games Arcade Edition]]'', with recommended events of [[110m Hurdles (Mario & Sonic at the Rio 2016 Olympic Games Arcade Edition)|110m Hurdles]] and [[Trampoline (Mario & Sonic at the Rio 2016 Olympic Games Arcade Edition)|Trampoline]]. Here, he has average power, above average speed, and good technique.

====''Mario & Sonic at the Olympic Games Tokyo 2020''====
Luigi reappears in ''[[Mario & Sonic at the Olympic Games Tokyo 2020]]'' as an All-Around type playable character, now wearing appropriate sporting clothing depending on the event. In addition to being playable in the Tokyo 2020 events, he is also one of the eight characters that are playable in the Tokyo 1964 events, using his appearance from ''Super Mario Bros.''. In the game's Story Mode, Luigi accidentally turns on the [[Tokyo '64]] console and gets Mario, Sonic, Toad, Bowser, and Dr. Eggman stuck in the game and then works with Tails to try to help get them out. 

Luigi is also an All-Around playable character in ''[[Mario & Sonic at the Olympic Games Tokyo 2020 - Arcade Edition]]'', where he has the same statistics as the arcade version of the previous installment.

===''Mario Sports Mix''===
Luigi appears in ''[[Mario Sports Mix]]'', where he is classified as an all-rounder (all-around in North America) type character. His speed is average, while he has an above-average technique, though his power is below average. His special move involves Luigi pulling out his [[Poltergust 3000]] from ''Luigi's Mansion'' to suck his opponents toward him, followed by firing the ball at the intended target. Luigi also has a court based on [[Luigi's Mansion (Mario Sports Mix)|his mansion]] that can be played on during the Volleyball and Basketball modes.

===''Dr. Mario'' series===
[[File:Dr Mario World - Dr Luigi.png|thumb|150px|left|'''Dr. Luigi''' from ''Dr. Mario World'']]
In ''[[Dr. Luigi]]'', Luigi gains the role of a doctor, much like his [[Dr. Mario|brother's persona]]. In ''Dr. Luigi'', his appearance is similar to Dr. Mario's, but Luigi wears his [[cap]] instead of a doctor's head mirror. In ''[[Dr. Mario: Miracle Cure]]'', Luigi gains a head mirror to wear. Like Dr. Mario, Luigi in his doctor persona makes use of [[Capsule]]s to defeat [[Virus]]es. In a similar fashion to Dr. Mario, Dr. Luigi will toss capsules that the player has to control in order to eliminate the Viruses.

It has been suggested that Dr. Luigi has a more laid-back personality than his brother, as in the introduction cutscene to ''Dr. Luigi'', he is seen walking slowly with a tired look on his face. After he sees the Viruses, however, he becomes shocked and prepares capsules for use, now looking worried.<ref>http://www.youtube.com/watch?v=A_HDOXAMnZo</ref>

Dr. Luigi returns as an unlockable playable character in ''[[Dr. Mario World]]''. Dr. Luigi is a reward in [[World 4 (Dr. Mario World)|World 4]]'s special stage since version 1.2.0, though beating the stage prior to the update will allow him to be obtainable through the doc box. His skill in stage mode is eliminating random viruses in an L shape, in which a spot is chosen, followed by clearing downward and then rightward, after which an image of an "L" is formed. Dr. Luigi also struck a pose while the skill is in effect. Prior to version 2.3.0, this skill cleared six spaces (four down followed by two right), but since that version, it clears eight spaces (five down followed by three right) and the targeted path will always include a virus at the corner if any are still present and can be eliminated in the stage. In versus mode, his skill is different in that it prevents opponents from rotating their [[capsule]]s, and lasts longer and/or has a faster-charging skill gauge at higher levels.

===''Captain Toad: Treasure Tracker''===
In ''[[Captain Toad: Treasure Tracker]]'', [[List of Luigi sightings in Captain Toad: Treasure Tracker|8-bit sprites of Luigi]] are hidden across many of the game's levels, similar to ''[[Super Mario 3D World]]''.

===''Puzzle & Dragons: Super Mario Bros. Edition''===
[[File:PDSMBE-SuperLuigi.png|thumb|Luigi in ''Puzzle & Dragons: Super Mario Bros. Edition'']]
In ''[[Puzzle & Dragons: Super Mario Bros. Edition]]'', Luigi is one of the main characters. If Luigi is selected as the leader, he can call on others as a helper. If anyone else is the leader, Luigi can be called on as a helper. Luigi shares the same number of forms as Mario, having eighteen forms, all of which are based on [[List of Power-Ups|power-ups]] from other games and can be seen [[Puzzle & Dragons: Super Mario Bros. Edition#Luigi|here]].

===''Minecraft''===
In the Super Mario Mash-up in ''[[Minecraft]]'', Luigi appears as a playable skin. Luigi wearing the [[Poltergust 5000]] and [[Tanooki Mario|Kitsune Luigi]] also appear as skins.

===''Mario Sports Superstars''===
Luigi appears in ''[[Mario Sports Superstars]]'' as a Balance type character in most sports; in tennis, he is the similar All-Around type instead. Due to this, Luigi has no glaring weaknesses in his stats, but he does not excel in any one stat in particular. In golf, Luigi's default drive is 209 yards, and his shots travel low in a fade trajectory.

===''Mario + Rabbids'' series===
====''Mario + Rabbids Kingdom Battle''====
[[File:MRKB_Luigi_Stats.png|thumb|Luigi in ''Mario + Rabbids Kingdom Battle'']]
Luigi appears as a playable character in ''[[Mario + Rabbids Kingdom Battle]]'' as one of the playable characters. Like with the others present at the statue inauguration at the beginning of the game, Luigi was sucked into the vortex linking the [[Rabbid]]s to the Mushroom Kingdom. He was later seen being terrorized by [[Pirabbid Plant]] in the level [[Brother, Where Art Thou?]], forcing Mario, [[Rabbid Luigi]], and [[Rabbid Peach]] to rescue him. Luigi promptly joins the group once the level is completed.

Luigi is a character with high offense and maximum mobility, though his defense is very low. He is the only character with access to [[List of weapons in Mario + Rabbids Kingdom Battle#Precision|Precision weapons]] as his main set of weapons and he uses [[List of weapons in Mario + Rabbids Kingdom Battle#Sentry|Sentry weapons]] as his secondary set.

Luigi is briefly present in the opening cinematic for ''Mario + Rabbids Kingdom Battle''{{'}}s [[Donkey Kong Adventure]] DLC, where he, alongside Mario and Rabbid Luigi, tries to stop Rabbid Peach from disappearing with [[Beep-0]], the  [[Time Washing Machine]], [[Rabbid Kong]], and a few Rabbids, but fails to do so.

====''Mario + Rabbids Sparks of Hope''====
Luigi returns as a playable character in ''[[Mario + Rabbids Sparks of Hope]]''. Luigi is playable from when the heroes arrive on [[Beacon Beach]], and throughout the game he helps the other heroes defeat [[Cursa]] and save the galaxy. He now wields the Sharpshooter,<ref> https://www.nintendo.com/store/products/mario-plus-rabbids-sparks-of-hope-gold-edition-switch/ </ref> a weapon shaped like a bow. It hits harder the farther the user is away from the enemy.<ref> https://youtu.be/0NB5rYSE5_E </ref> His Steely Stare technique returns from the first game, and is able to unlock double jump in the skill tree.<ref> https://www.ubisoft.com/en-us/game/mario-rabbids/sparks-of-hope/news-updates/54KqtyUg25UlrGQ20LC0ga/mario-rabbids-sparks-of-hope-a-deep-dive-into-combat-and-hero-archetypes </ref>

===''The Super Mario Bros. Movie''===
[[File:TSMBM Luigi.png|thumb|100px|Artwork of Luigi as he appears in ''The Super Mario Bros. Movie'']]
{{quote|I knew saving Brooklyn was a bad idea...|Luigi|The Super Mario Bros. Movie}}
Luigi appears as a major character in ''[[The Super Mario Bros. Movie]]''. In the English version of the movie, he is voiced by [[Charlie Day]]. He and Mario initially worked under [[Foreman Spike|Spike]], but soon leave him and begin operating their own plumbing business together, [[Super Mario Bros. Plumbing]], serving [[Brooklyn]] and [[List of implied locations#Queens|Queens]]. However, the brothers end up separated from each other in the Mushroom Kingdom, with Luigi ending up in the [[Dark Land]]s. He flees from a horde of [[Dry Bones]] and hides in a [[castle]], but is brought to [[Bowser]] by some [[Shy Guy]]s. Luigi is then interrogated by Bowser for information that he is reluctant to share about Mario, ultimately doing so as Bowser begins to yank off parts of his mustache.

He is then imprisoned with other prisoners such as the [[Penguin King]] and [[Lumalee]]. He and the other prisoners are later nearly sacrificed in [[lava]] during [[Princess Peach|Peach]] and Bowser's wedding, but [[Tanooki Mario]] saves him. Luigi and company are then sent back to Brooklyn, where Luigi protects Mario from Bowser's [[Fire Breath]] with a manhole cover during their battle. The brothers then use Bowser's dropped [[Super Star]] to become [[Invincible Mario|invincible]] and defeat Bowser and his army, at which the citizens of Brooklyn begin cheering for the brothers. The two of them then take up residence in the Mushroom Kingdom.

Similarly to Mario, Luigi's design in the movie retains his general proportions but differs from the games slightly. He has slightly smaller hands, mustache, nose, and overall buttons; rounder eyes and cap; a shirt collar; scaled down hair features; more detail on his teeth and hair; and a pocket on his overalls. Luigi carries a toolbox and flashlight when plumbing. When he winds up in the Dark Lands, Luigi uses his flashlight and calls Mario's name similarly to how he does so in ''[[Luigi's Mansion]]''. Mario affectionately refers to him as "Lu" a few times, a nickname first used in the movie.
