{{quote|Uh-oh, Baby Luigi time!|Baby Luigi|Mario Kart: Double Dash!!}}
'''Baby Luigi''' is the infant form of [[Luigi]]. In the ''[[Yoshi's Island (series)|Yoshi's Island]]'' series, he is kidnapped several times by [[Kamek]], where [[Yoshi]], who is protecting [[Baby Mario]], is required to rescue him. Baby Luigi has also appeared as a playable character alongside his older self in the ''[[Mario Kart (series)|Mario Kart]]'' series and other spinoff titles, as well as being one of the major protagonists of ''[[Mario & Luigi: Partners in Time]]''.

Adult Luigi has been portrayed as an infant in other media, namely in ''[[The Adventures of Super Mario Bros. 3]]'' episode [[Toddler Terrors of Time Travel]] and the ''[[Family Album "The Early Years"]]'' comic, though the Baby Luigi character is considered a distinct entity from these forms.
==History==
===''Yoshi's Island'' series===
====''Super Mario World 2: Yoshi's Island'' / ''Yoshi's Island: Super Mario Advance 3''====
Baby Luigi is first seen with Baby Mario during his debut in ''[[Super Mario World 2: Yoshi's Island]]'' (and its remake ''[[Yoshi's Island: Super Mario Advance 3]]'') when he and the [[Stork]] carrying him are captured by Kamek and taken to [[Bowser's Castle]]. After he is rescued by Yoshi and Baby Mario, the stork safely delivers Baby Mario and Baby Luigi to their parents. In ''Super Mario Advance 3'', Baby Luigi is seen crying inside a bubble above Bowser's Castle on the world selection map screen.

====''Yoshi's Island DS''====
[[File:Toadies and Baby Luigi YTnG artwork.jpg|thumb|left|upright=0.85|Baby Luigi is often kidnapped by [[Toady|Toadies]].]]
Bowser and Kamek, in their quest searching for the seven [[star children]], once again kidnap Baby Luigi, who is one of the kidnapped babies in ''[[Yoshi's Island DS]]''. After Baby Mario, [[Baby Peach]], [[Baby Wario]], [[Baby DK]], and Baby Bowser team up, they all proceed to rescue him. Baby Luigi hides at the time Bowser and Kamek are checking the toddlers for stars, and, as a result, he never finds out that he is a star child himself.

====''Yoshi's New Island''====
Baby Luigi appears in ''[[Yoshi's New Island]]''. In the game, he and Baby Mario are delivered to the wrong parents, setting the Stork off, continuing the search. Baby Luigi has been kidnapped by Kamek once again, but this time in [[Egg Island]], so the Yoshis and Baby Mario go on an adventure to save him. After they save him, Baby Luigi and Baby Mario get delivered to the right parents.

===''Super Mario-kun''===
[[File:BabyLuigiSnowmanSMK36.jpg|thumb|Baby Luigi in Volume 36 of the ''Super Mario-kun'']]
Baby Luigi has made several appearances in the Japanese manga, ''[[Super Mario-kun]]''. He first appears in Volume 14, which is based on ''Super Mario World 2: Yoshi's Island''. In this comic, the present Mario and Luigi travel to the past to stop Bowser from helping Kamek kidnap Baby Mario and Baby Luigi, and they also aid Yoshi to deliver the Baby Mario Bros. to their parents. As in the game, Kamek ambushes the stork and makes off with Baby Luigi, with Baby Mario dropping with Mario, Luigi, and Yoshi. As Baby Luigi arrives to the castle, Bowser does not appear to take a liking to Baby Luigi, despite Baby Luigi being playful, and ends up biting his head and even giving a spanking after Baby Luigi urinates on him. Later on, Bowser and Kamek torture Baby Luigi, and then Kamek disguises himself as Baby Luigi to throw the three heroes off.

Baby Luigi later appears in Volume 35, Volume 36, and Volume 37, which is based off ''[[Baby_Luigi#Mario_.26_Luigi:_Partners_in_Time|Mario & Luigi: Partners in Time]]''. A portion of volume 37 is featured in the English compilation of the series, ''Super Mario Manga Mania''. His role in those volumes mirror that in the game it was based off of, with several key differences. In the beginning of Volume 36, Baby Luigi uses Baby Mario filled with water as a weapon and sprays Mario and Luigi with it. Baby Mario and Baby Luigi also use the Baby Drill as an attack rather than a method used to find beans: they attack Mrs. Thwomp and the adult Mario Bros. with the technique.

When the characters arrive at [[Star Hill]], Baby Luigi builds a snowman. When the brothers go into peril with the [[Commander Shroob]], the snowman attempts to save them, but ultimately gets destroyed by the Commander Shroob. Baby Luigi, thinking that he is useless, is then told by the snowman spirit that the flower on its head turned into an [[Ice Flower]]. Baby Luigi then uses an [[Ice Flower]] on the Commander Shroob and the [[Support Shroob]]s, also unintentionally freezing his allies in the process.

Later in the comic, Baby Luigi teams up with Luigi against Mario and Baby Mario, after they were provoked by a [[Tanoomba]] masquerading as them. They both use shell armor, the [[Copy Flower]], the [[Cannonballer]], the [[Ice Flower]], and the [[Fire Flower]] against Mario and Baby Mario, also while suffering their attacks as well. The four characters eventually find out that the Tanoomba tricked them and then teamed up to defeat the Tanoomba. The Tanoomba asks for forgiveness after the attack, and the four characters accepted it.

Baby Luigi appears only in the cover of Volume 40, which is a tribute to the series.

===''Club Nintendo''===
Baby Luigi appears in a ''Super Mario'' comic in the German magazine, ''[[Club Nintendo (German magazine)|Club Nintendo]]''. As the comic is based off ''Super Mario World 2: Yoshi's Island'', he reprises the role of the hostage.

===''KC Deluxe''===
[[File:Baby Mario Baby Luigi Yoshi - KC Mario manga.png|thumb|left|Baby Luigi's appearance in the ''KC Mario'' manga]]
Baby Luigi makes an appearance in all three volumes of the ''Super Mario World 2: Yoshi's Island''-based volumes (volumes 33, 34, and 35) of the ''[[KC Deluxe]]'' manga. While in the first and second mangas, he plays the same role as he did in ''Super Mario World 2: Yoshi's Island'', he plays a more proactive role in the third volume, where, in original story arcs not based off the game, he adventures alongside Baby Mario and Yoshi, often supporting them such as piloting a Yoshi Helicopter to fix a broken railroad to help a passenger-filled train.

===''4-koma Gag Battle''===
[[File:Super Mario Daishuugou - Baby Luigi.jpg|thumb|200px|Baby Luigi from the ''Super Mario Daishuugou'' volume of the ''4-koma Gag Battle'' series]]
In the ''Super Mario Daishuugou'' volume of the ''[[4-koma Gag Battle]]'' released in 1996, one of the gags portrays a spin on the introduction of ''Super Mario World 2: Yoshi's Island''. After Kamek steals Baby Luigi from the stork and Baby Mario dies when he hits the ground as a Yoshi fails to catch him, Baby Luigi is seen contemplating the future as the lead of the ''Super Mario'' franchise, thinking about ''Luigi 1, 2, and 3'', ''Luigi World'', ''Luigi Kart'', and ''Luigi RPG''. Kamek, who is disturbed by him, ends up tossing him out.

===''Dr. Mario-kun''===
[[File:DrMarioKun - December2006 - BabyMarioBros.jpg|thumb|left|Baby Mario and Baby Luigi in Episode 48 from ''Dr. Mario-kun'']]
Baby Luigi makes sporadic appearances in ''Comic Bom Bom''{{'}}s ''[[Dr. Mario-kun]]'', sometimes being adult Luigi who transformed into him, other times having stand-alone appearances. In the May 2003 volume, adult Luigi and Wario first shrink, and then get turned into Baby Luigi and [[Tiny Wario]] respectively, with Tiny Wario bullying Baby Luigi. [[Dr. Mario]] fixes Baby Luigi and Tiny Wario by giving them a milk bottle, which turns him back into a regular-sized adult Luigi and Wario, though the side effect generates viruses designed after Luigi and Wario. In this appearance, Baby Luigi is portrayed as wearing longer pants, gloves, and shoes designed after Luigi's. This was fixed in Baby Luigi's later appearances in the series.

In Episode 48, released in December 2006 and loosely having elements based off ''[[Mario & Luigi: Partners in Time]]'', the comic begins with Dr. Mario and Nurse Toadstool reminiscing the times Mario and Luigi were babies, still jumping around and defeating the Koopa Troop. They then notice  [[Bowser Jr.]] and a red [[Virus]] strangely appearing in the pictures, who have traveled to the past to defeat Baby Mario and Baby Luigi. The story then cuts to the past, with Baby Mario defending Baby Luigi, where they fight back against Bowser Jr. and the red virus. After Bowser Jr. starts piloting a giant mech in the shape of Bowser's head, in the present, Dr. Mario, Nurse Toadstool, and Luigi meet up with a large Piranha Plant, who sends them back to the past to help Baby Mario and Baby Luigi defeat Bowser Jr. and the red virus; once they are both defeated, they start to face off against an evil timer.

The story arc continues in Episode 49, released in January 2007. After Dr. Mario fails to throw pills at the timer, the timer attacks and constricts Dr. Mario, which turns him into an 8-bit Mario. During the scene, Nurse Toadstool takes care of Baby Mario and Baby Luigi, holding them in her arms. After Baby Bowser and Bowser Jr. met each other, they escape on a [[Koopa Cruiser]]. Due to the evil timer earlier granting Luigi a large mustache, Luigi uses his mustache to fly the protagonists to the [[Koopa Cruiser]]. After the Piranha Plant downs the cruiser, the protagonists help 8 bit Mario out, with the combined power of Invincible adult Mario Bros. with the Baby Mario Bros. to defeat the timer. After the timer is defeated, the characters return to their respective time periods.
{{br}}

===''Super Smash Bros.'' series===
In the [[Super Smash Bros. (series)|''Super Smash Bros.'' series]], Baby Luigi first appears in the form of a mention in Baby Mario's [[Trophy (Super Smash Bros. series)|trophy]] in ''[[Super Smash Bros. Melee]]''. Similarly, he was only mentioned in the Yoshi New's Island trophy of ''[[Super Smash Bros. for Nintendo 3DS]]'' trophy.

Baby Luigi has sometimes appeared in the form of a collectible item. In ''[[Super Smash Bros. Brawl]]'', he appears on a [[Sticker (Super Smash Bros. Brawl)|sticker]], depicting ''Mario & Luigi: Partners in Time'' artwork of him riding on Luigi's back, and the sticker, which can only be used by Mario, Luigi, Yoshi, Peach, or Bowser, raises the user's launch power by 5 points. ''[[Super Smash Bros. for Wii U]]'' features a Baby Luigi trophy that can be bought from the [[smashwiki:Trophy Shop|Trophy Shop]]; though it has the [[Mushroom]] [[smashwiki:Symbol|symbol]], representing the [[Super Mario (franchise)|''Super Mario'' franchise]], the [[smashwiki:Trophy Box|Trophy Box]] categories it as part of the [[Yoshi's Island (series)|''Yoshi's Island'' series]]. In ''[[Super Smash Bros. Ultimate]]'', while Baby Luigi does not have a stand-alone [[Spirit (Super Smash Bros. Ultimate)|spirit]], he appears in two spirits alongside Baby Mario, one being the [[Goo-Goo Buggy]] and the other being the [[Stork]] carrying them from ''[[Yoshi's New Island]]''. The Goo-Goo Buggy spirit is unlocked from the challenge board when players KO three characters in less than a minute in a match.

===''Mario Kart'' series===
====''Mario Kart: Double Dash!!''====
[[File:BabyDD.png|thumb|x180px|Baby Luigi's first playable appearance is in ''[[Mario Kart: Double Dash!!]]'']]
Baby Luigi makes his playable debut in ''[[Mario Kart: Double Dash!!]]'', his weight class being light-weight. Baby Luigi's default partner is Baby Mario and his [[kart]] is the [[Rattle Buggy]]. Their special item is a [[Chain Chomp]], which can pull them forward at high speeds and knock over any opponent who gets in the way. Baby Mario and Baby Luigi also have a course in this game, which is [[GCN Baby Park|Baby Park]]. Baby Mario and Baby Luigi are used as staff ghosts in both Baby Park and [[GCN Sherbet Land|Sherbet Land]]; Baby Luigi is the dominant character of Sherbet Land. Also, internal file names name the course Baby Mario and Baby Luigi (who are packed into one file), and the Baby Park staff ghost simply "BabyLuigi", even though Baby Mario is the dominant character of the pair.

====''Mario Kart Arcade GP 2''====
Baby Mario and Baby Luigi also make a cameo appearance in ''[[Mario Kart Arcade GP 2]]'', with several notable characters. They are seen throughout [[Yoshi Park 1]] and have a [[Gallery:Sponsors in the Mario Kart series|sponsor]], Baby Land, seen in [[Mario Highway]], [[Mario Beach]], [[DK Jungle (arcade)|DK Jungle]], and [[Bananan Ruins]]. In Yoshi Park 1 and Yoshi Park 2, they, alongside other characters, can be seen riding the swing ride.

====''Mario Kart Wii''====
[[File:Babyluigi.png|thumb|left|Baby Luigi in ''Mario Kart Wii'']]
Baby Luigi later returns to the ''Mario Kart'' series as an unlockable character in ''[[Mario Kart Wii]]'' as a small driver, meaning his karts generally have high acceleration, handling, drifting, and [[Mini-Turbo]], but generally lower speed and weight. Baby Luigi's karts are the same as the other light-weight characters, except that his are green and share the same trademark ''L'' emblem as Luigi. Unlocking eight Expert Staff [[Ghost (Mario Kart series)|Ghost]] Data in [[Mario Kart Wii#Modes of Play|Time Trials]], winning 100 WFC Ghost Races, or playing 3,150 races unlocks Baby Luigi. He is tied with [[Baby Daisy]] for having the best speed bonus for small drivers, which makes any vehicle have a slightly higher top speed. Baby Luigi's biggest bonus is his weight bonus, and he is tied with Baby Mario in this category. Baby Luigi is used as a staff ghost in {{classic-link|N64|Sherbet Land}}, making this the second consecutive time where Baby Luigi is the staff ghost for a course named "Sherbet Land". [[Daisy Circuit]] features a statue of him dancing with Baby Daisy.

====''Mario Kart 8'' / ''Mario Kart 8 Deluxe''====
[[File:MK8 Baby Luigi and Blooper Artwork.png|thumb|Baby Luigi getting sprayed on by a Blooper from ''Mario Kart 8'', possibly referencing ''[[Mario Kart DS]]'' [[:File:MKDS Mario Peach Luigi and Blooper Artwork.png|artwork]] of his [[Luigi|adult]] counterpart also getting sprayed by a Blooper]]
Baby Luigi returns as a playable racer in ''[[Mario Kart 8]]''. Unlike in ''Mario Kart Wii'' and like Baby Mario, Baby Luigi is a starter, like in ''Mario Kart: Double Dash!!'', and like the other baby characters, his emblem is altered to differentiate his from Luigi's; the colors are reversed to make a white L in a green background. There are also bonnet frills around the insignia, a feature that was first introduced to Baby Mario and Baby Peach in ''[[Mario Tennis Open]]''. As in all ''Mario Kart'' games he is playable in, he is a lightweight driver. His group specific stats, with the rest of the playable baby characters and [[Lemmy|Lemmy Koopa]], heavily favor acceleration, handling, and grip at the cost of speed and weight, making him and the rest of the characters the lightest in the game. Nin★Massim's staff [[Ghost (Mario Kart series)|ghost]] uses Baby Luigi for [[Water Park]]. The [[Animal Crossing x Mario Kart 8]] DLC pack returns Baby Mario and Baby Luigi's track, {{classic-link|GCN|Baby Park}}, where the starting banner is updated to 3D artwork of Baby Mario and Baby Luigi rather than the ''Yoshi's Island'' art style originally used. When the CPU uses Baby Luigi, he, alongside the other baby characters, occasionally uses the [[Biddybuggy]] body paired with [[Standard (tire)|Standard tires]].

''[[Mario Kart 8 Deluxe]]'', a port of ''Mario Kart 8'', returns all playable characters from said game, including Baby Luigi. ''Mario Kart 8 Deluxe'' has changed his stats, so he now shares stats with [[Baby Mario]], [[Dry Bones]], and small [[Mii]]s. He has a higher top speed and weight stats than [[Baby Peach]], [[Baby Daisy]], [[Baby Rosalina]], and [[Lemmy|Lemmy Koopa]], as well as having equal or better acceleration than them, though he has lower handling, traction, and mini-turbo stats to compromise. His signature vehicle combo is [[Mr. Scooty]] with the [[Roller]] tires and [[Super Glider]].

====''Mario Kart Tour''====
Baby Luigi appears as a playable character in ''[[Mario Kart Tour]]'', available starting with the 2019 [[Halloween Tour (2019)|Halloween Tour]]. He is classified as a Normal driver, and his [[Special skill (Mario Kart Tour)|special skill]] is the [[Boomerang Flower]]. As of the [[Sydney Tour (April–May 2021)|April–May 2021 Sydney Tour]], Baby Luigi and [[Baby Daisy]] are the only babies without playable variants.

In pre-release material, including the beta test,<ref name=GameXplain>{{cite|language=en|author=GameXplain|date=May 22, 2019|url=youtu.be/fQ-5dZCCBfQ|title=How Does Mario Kart Tour Play? Beta Participants Are Sharing Impressions Online|publisher=YouTube|accessdate=May 22, 2019}}</ref> Baby Luigi was a common driver (early name of Normal) with the Boomerang Flower as his special skill. His favorite course was [[DS Luigi's Mansion]], while his favored course was [[SNES Mario Circuit 1]].

Baby Luigi does not count towards completing challenges that require the player to perform certain actions using Luigi in a race,<ref>{{cite|author=[[User:Koopa con Carne|Koopa con Carne]]|language=en|date=May 11, 2022|url=youtu.be/iATXcXb39cI|title=Baby Luigi is not Luigi|publisher=YouTube|accessdate=May 11, 2022}} (Gameplay footage showing that the counter of the "Get 1st place in a race 30 times using Luigi." [[List of challenge cards in Mario Kart Tour#Doctor Challenges|Doctor challenge]] does not increase upon placing first in a race as Baby Luigi.)</ref> even though variants of the latter, such as Luigi (Vacation), do.
{{br}}

===''Mario Power Tennis''===
Both Baby Mario and Baby Luigi can be {{file link|MarLulOpening.PNG|seen in the crowd}} in the opening of ''[[Mario Power Tennis]]''. They can be seen only in the first match where Mario and Luigi beat [[Wario]] and [[Waluigi]].

===''Yoshi Touch & Go''===
Baby Luigi is one of the main characters in ''[[Yoshi Touch & Go]]''. He and Baby Mario are carried by the stork; the stork gets hit by Kamek, which promptly drops both Baby Mario and Baby Luigi whenever a mode is selected in the title screen. In Score Attack mode, if the player hits over 300 points, Baby Luigi is seen riding the Stork at the end. In Time Attack mode, Baby Luigi is held captive by Kamek's [[Toady|Toadies]]. To rescue Baby Luigi, Yoshi must fling [[Yoshi Egg]]s at the Toadies carrying him. In Marathon mode, if the Yoshi gets defeated, Baby Luigi is seen riding the Stork, who flies to the area the Yoshi has been defeated. In the game's multiplayer mode, Vs. Battle mode, the second player's [[Yoshi (species)|Yoshi]] totes Baby Luigi.

===''Mario Baseball'' series===
====''Mario Superstar Baseball''====
Baby Luigi is an unlockable character in ''[[Mario Superstar Baseball]]''. He is unlocked by completing [[Mario Superstar Baseball#Challenge Mode|Challenge Mode]] with [[Yoshi Eggs (team)|Yoshi's team]]. Baby Luigi is classified as a speed character, which means he excels at stealing bases and maneuvering as an outfielder. Baby Luigi's special ability is [[Wall Jump]], which enables him to rebound off walls to catch any would-be home-runs. Baby Luigi's worst stat is his batting, making it very difficult for him to launch balls far, and his fielding stat is low, which makes him make mistakes more often on the field and his thrown balls in the outfield travel slowly. In this game, Baby Luigi has positive [[chemistry]] with Baby Mario and Yoshi, referencing their roles in ''Super Mario World 2: Yoshi's Island'', but negative chemistry with Boo, King Boo, and Shy Guy. Baby Luigi has six Star Missions in the game, and three of them involve taking advantage of his high speed stat: they require Baby Luigi to steal at least one base and dropping a [[Wikipedia:Squeeze play (baseball)|squeeze bunt]]. His unique Star Mission is "Win Piranha Panic with no damage!", where Baby Luigi must score first in the [[Piranha Panic]] minigame without being hit by either [[Piranha Plant]] fireballs or other players' [[Bob-omb]]s.

====''Mario Super Sluggers''====
[[File:BabyLuigi-Batting-MSS.png|thumb|left|Baby Luigi prepares to bat in ''Mario Super Sluggers''.]]
Baby Luigi is a playable character in ''[[Mario Super Sluggers]]''. He is available from the start, unlike the previous game. He has better fielding skills than in ''Mario Superstar Baseball'', while his running is still fast and his pitching remains average; as with other babies, Baby Luigi has poor stamina while pitching and tires out very quickly. Once again, his batting is among the worst in the game, and his special ability is [[Super Jump (Mario Baseball series)|Super Jump]] rather than Wall Jump. Super Jump enables Baby Luigi to jump higher than other characters who do not have this ability. In [[Mario Super Sluggers#Challenge Mode|Challenge Mode]], Baby Luigi is trapped by a bridge that was raised without warning by [[Bowser Jr.]] in [[Mario Stadium (baseball stadium)|Mario Stadium]]. In order to access the bridge, players first need to defeat the [[Magikoopa]] guarding the switch. Players can then rescue him in by flipping the lever of the switch in the proper direction to open up a bridge. The arrow directions to flipping the lever are inscribed on the sand on the beach nearby. After Baby Luigi is rescued, he points player characters towards the Mario Stadium, with Lakitu interpreting his incoherent baby onomatopoeia, saying that Baby Mario is trapped in there and he wants to rescue Baby Mario himself, thus joining the team.

===''Mario & Luigi'' series===
====''Mario & Luigi: Partners in Time''====
[[File:Luigi & Baby Luigi PiT.png|thumb|x180px|Baby Luigi and [[Luigi|his older self]] are partnered together in ''Mario & Luigi: Partners in Time'']]
Baby Luigi plays a starring role in ''[[Mario & Luigi: Partners in Time]]''. Here, he teams up with Mario, Luigi, and Baby Mario to fight the [[Shroob]] invasion in the past. Most of the game, he travels piggyback on Luigi but ventures with Baby Mario if the adult brothers throw them. In battle, Baby Luigi battles identically to Baby Mario. His default ability is jumping on foes, which he cannot perform on spiked enemies. Baby Luigi, along Baby Mario, later acquire hammers to injure spiked foes and be able to venture further in the game. For all attacks, he must time the attack for the most damage. If not, Baby Luigi either does a hurt-like pose after a jump, drops the hammer head, or trips and lands on his face when using the hammer if the button is pressed too early. Baby Mario and Baby Luigi also acquire overworld abilities in the game: the [[Baby Drill]], which enables them to dig underground; the [[Baby Spin]], which allows them to reach hard to reach areas that Mario and Luigi cannot access, even with the [[Spin Jump]]; and the Baby Cakes, which enables them to slip underneath cracks that cannot be accessed by the Baby Drill and float on winds due to compressed weight. He can also use Bros. Items, but he needs a partner to do so. If Luigi faints, Baby Luigi drags Luigi out of battle and fights in his place; if Baby Luigi faints, Baby Mario or Mario carries him, and his added weight hinders dodging capabilities. If Baby Mario faints, Baby Luigi carries him when enemies are attacking, and it also hinders his jumping abilities. Stat-wise, he differs from Baby Mario in most ways. Baby Luigi has slightly less speed and less attack, but more [[Heart Point|HP]] and defense. However, he has more speed and less HP, defense, attack, and [[stache]] than his adult counterpart, Luigi.

====''Mario & Luigi: Paper Jam''====
Baby Luigi makes a cameo in ''[[Mario & Luigi: Paper Jam]]'', where he appears on Luigi's [[Battle Card (Mario & Luigi: Paper Jam)#Luigi|LV 2 Duo Card (Luigi + Mario)]] alongside his brother and their adult counterparts.
{{br}}

===''Luigi's Mansion: Dark Moon''===
Baby Luigi is mentioned by [[King Boo]] at one point in ''[[Luigi's Mansion: Dark Moon]]'' when he mockingly remarks how he cannot tell the difference between him and the adult Luigi.<ref>{{cite|quote={{file link|DarkoftheMoonBabyLuigi.png|Mwah ha ha! Now what do we have here? Why, if it isn't my old pal Luigi! Or is it '''Baby Luigi'''? I can't tell the difference.}}|author=King Boo|date=2013|language=en|publisher=Nintendo|title=''Luigi's Mansion: Dark Moon''}}</ref>

===''Mario Sports Superstars''===
[[File:BabyLuigiHorseRacingMSS.png|thumb|left|Baby Luigi riding a [[horse]] in ''Mario Sports Superstars'']]
Baby Luigi is playable as a captain-type character in ''[[Mario Sports Superstars]]'', where he makes his overall debut playing soccer, tennis and golf.<ref name="NintendoDirect">{{cite|author=Nintendo of America|date=September 1, 2016|language=en-us|url=youtu.be/IpXQtFbRChg|title=Nintendo Direct 9.1.2016|publisher=YouTube|accessdate=June 30, 2024}}</ref> Throughout the five sports, Baby Luigi's common type is his speed, with the exception of golf and tennis, which means that he is able to move around the field quickly as well as emphasizing on [[horse]] top speed in horse racing. In soccer, Baby Luigi trades power for speed and technique, meaning his shots are less powerful, but they are more accurate, and he can attack balls and maneuver around more easily. In baseball, Baby Luigi is a left-handed batter and a right-handed pitcher who is very poor at batting, but he excels at speed-related activities such as fielding and base-running and his pitching velocity stat is on par with his speed; in fact, if Baby Luigi becomes a superstar character in baseball, his pitching velocity becomes his best stat. When Baby Luigi is pitching, he has access to Fastballs, Screwballs, Sinkers, and Sliders, where, compared to Baby Mario, Baby Luigi trades the Curveball for a Sinker and a bigger Screwball zone comparable to Baby Mario's Slider zone. Baby Luigi's special move when he is pitching is a slider. In horse racing, Baby Luigi has very similar stats with his brother, Baby Mario; he has high horse top speed, high acceleration, with below average control and very low stamina, meaning that his horses are harder to control and they tire out more quickly and it takes longer for them to recover their stamina. Baby Luigi's horses have the highest speed stat in the game, being slightly higher than Baby Mario's, the second highest top speed, though Baby Mario has higher stamina than Baby Luigi to make up for the lower speed. In horse racing, the CPU Baby Luigi uses the brown default technical horse. In Pro difficulty, the CPU Baby Luigi equips his horse with the green Asian accessories.

Baby Luigi has a different type classification in tennis, where he is a Technical character rather than a speed-focused character, sharing this classification with [[Princess Peach]]. Technical characters such as Baby Luigi emphasize on ball control and accuracy, hitting to the edges of the court more easily. Baby Luigi has excellent volleying power, where he can smash balls at the net at quick speeds across the court. Baby Luigi's movement speed is on par with the other Speed classified characters. However, Baby Luigi's reach is very low due to his size, making it very difficult for him to hit lobs and balls out of his reach if his speed cannot cover it. Baby Luigi also has very low stroke abilities, so if he hits shots after they bounce, the ball will not travel quickly.

[[File:BabyLuigiGolfMSS.png|thumb|Baby Luigi golfing on [[Crystal Beach]] in ''Mario Sports Superstars'']]
Due to golf using different mechanics than the other four sports, Baby Luigi does not rely on speed. Baby Luigi's shots have a fade tendency to them, meaning that, assuming he is right-handed, his shots hit towards the left before curving to the right. Baby Luigi has a maximum drive of 187 meters/205 yards, which is the shortest in the game. However, he makes up for those traits by having excellent sweet spot and control stats, meaning it is more difficult to whiff shots, especially in very penalizing terrain such as [[rough]], and if he hits the ball outside the sweet spot meter, he will not receive a large accuracy penalty. Baby Luigi additionally hits balls very low, meaning that while it is more difficult for him to traverse higher elevations and hit over trees, his shots are less affected by the wind. When Baby Luigi is starred, his drive increases to 219 meters/240 yards, with his sweet spot and control suffering only slightly, due to him having the shortest drive in the game.

If Baby Luigi attains a par, he skips and stares at the camera. If he attains a birdie, he recreates [[Luigi]]'s birdie animation by sliding and jumping around. If he attains an eagle, bubbles appear, followed by Baby Luigi himself and items such as [[coin]]s, [[Super Mushroom]]s, and [[Fire Flower]]s being encased in them as well. If he attains a bogey, he falls on the ground, and if he attains worse than a bogey or gives up, he falls on the ground again and cries.

As all playable characters, Baby Luigi receives five [[amiibo]] cards for each sport from the [[List of Mario Sports Superstars amiibo cards|game's series]] of amiibo cards. Only his tennis and golf amiibo cards use artwork from past games; the rest of them receive original artwork. When players tap Baby Luigi's cards in, they receive [[1-Up Mushroom]]-themed gear that Baby Luigi can optionally use, though the gear is only for aesthetics purposes. Players can also use 1-Up Mushroom gear for Baby Luigi if they have unlocked it through purchasing randomly packed digital cards.

===''Dr. Mario World''===
[[File:DrMarioWorld BabyLuigi.jpg|thumb|left|200px|Artwork of Dr. Baby Luigi]]
In ''[[Dr. Mario World]]'', Baby Luigi appears as an unlockable playable character (referred to as '''Dr. Baby Luigi'''). Dr. Baby Luigi is available on September 5, 2019 alongside [[Baby Mario|Dr. Baby Mario]], [[Baby Peach|Dr. Baby Peach]], and [[Baby Daisy|Dr. Baby Daisy]].<ref>{{cite|author=Drmarioworld_EN|date=September 3, 2019|url=x.com/Drmarioworld_EN/status/1168720698845450240|title=<nowiki>Yellow: "The second doctor appearing on Sep 5 is Dr. Baby Luigi! Wow, I didn't see that coming! It must take a lot of brains to be a baby doctor. Hopefully this won't be too bad!" #DrMarioWorld</nowiki>|publisher=Twitter|language=en|accessdate=September 2, 2019}}</ref><ref>{{cite|author=CometMedal|language=en|date=July 9, 2019|url=x.com/CometMedal/status/1148655767022706695|title=Doctors in ''Dr. Mario World''|publisher=Twitter|accessdate=July 9, 2019}}</ref> Since version 1.2.0 of the game, in Stage Mode, Dr. Baby Luigi is unlocked when players clear the Special Stage of [[World 7 (Dr. Mario World)|World 7]]. In this game, he wears a white lab coat with a green tie that displays the letter "L", the clothing being too big for him. Like the other babies, he is equipped with an item: in this case a medicinal container with his emblem inscribed on it. While Baby Luigi's regular variant carries a blue-colored bottle, his unused rare variant carries a red bottle. 

Dr. Baby Luigi's skill changes objects into [[shell]]s in both stage and versus modes. In stage mode, it is represented by him throwing his bottle in the air and then catching it, while a bottle appears on the screen and moves to the object to transform it into a shell (if there is an object that can be changed). [[Virus]]es are targeted first for being changed before certain other objects are targeted. If an object like a virus or [[colorful crate]] is colored, the shell will have the same color as the changed object. [[Coin]]s, [[capsule]]s, objects that can eliminate viruses (e.g. [[Exploder]]) and objects that cannot be eliminated (e.g. [[Empty Block]]) are unaffected. In stage mode, only one object is changed, while in versus mode, one object is changed at level 1 while two objects are changed at level 2 and higher. In regards to the latter, the skill charges up faster at higher levels.

===''The Super Mario Bros. Movie''===
[[File:TSMBM BabyLuigi2.png|thumb|Baby Luigi in the ''The Super Mario Bros. Movie''.]]
Baby Luigi appears in a flashback [[Luigi]] has in the ''[[The Super Mario Bros. Movie]]'' while being captured by [[Shy Guy]]s and [[Snifit]]s in a hot air balloon. During the sequence, Luigi reminisces about a time when he was at a playground as a toddler, when a bully came and destroyed a toy castle Baby Luigi has been building, only for [[Baby Mario]] to come to his brother's defense, by pushing down the bully, giving him a flag, and standing by Baby Luigi's side. While the Baby Luigi design is accurate to the games, the soles of his shoes are colored green rather than white.

===''WarioWare: Move It!''===
Baby Luigi makes a cameo in the two-player version of the ''[[Super Mario World 2: Yoshi's Island (microgame)|Super Mario World 2: Yoshi's Island]]'' microgame in ''[[WarioWare: Move It!]]''. He is on an orange Yoshi, while his brother is on a blue Yoshi. He is a green palette swap of Baby Mario's sprite.

===Other appearances===
A full-color version of the Baby Luigi stamp from ''Mario Kart 8'' makes an appearance as one of the collectible badges a player can earn in the [[Nintendo eShop]] free-to-start application, ''[[Nintendo Badge Arcade]]''. He, alongside the other baby characters, appear in a ''Mario Kart''-themed Badge Catcher.

Baby Luigi, along with [[Baby Mario]], [[Baby Peach]], and [[Baby Daisy]], has also received some merchandising. He is featured as one of the minifigures of the Super Mario Figure Collection as well as being featured as part of the Furuta Choco Egg series. Baby Luigi is also one of the many plushies manufactured by [[San-ei]]. He, alongside Baby Mario and Baby Peach, are also featured in character-themed styluses. A Baby Luigi plush also part of the [[World of Nintendo]] line of Nintendo merchandise and he received a 2.5 inch [[Jakks Pacific]] figurine.

Baby Mario and Baby Luigi are featured in a [[LEGO Super Mario|LEGO ''Super Mario'']] set, "''[[Mario Kart (series)|Mario Kart]]'' - Baby Mario vs. Baby Luigi (72034)". He is piloting the [[Tri-Speeder]] with [[Slick]] tires.

==General information==
===Physical description===
[[File:BabyMarioBabyLuigiDifferences.png|thumb|Baby Mario and Baby Luigi's models from ''Mario Super Sluggers'']]
Baby Luigi has a similar appearance to Baby Mario. Both have black, beady eyes, large head to body ratios, and a large nose. As of ''[[Mario Kart: Double Dash!!]]'', Baby Luigi uses the same color scheme as [[Luigi|his adult counterpart]], except he wears green sneakers instead of brown work shoes and he lacks gloves. His green sneakers are usually a slightly darker shade of green compared to his hat and shirt, but some media depict the green as the same shade. His overalls are also short instead of long unlike the adult Luigi. He also has brown hair covered by his trademark [[Luigi Cap]]. The only major difference between Baby Mario and Baby Luigi is that Baby Mario wears a red shirt and [[Mario Cap|red cap]], while he wears a green shirt and green cap. Several minor differences from Baby Mario include his head shape, his eyebrows, his waist, and his sideburns. Also, Baby Luigi's sneakers are green instead of cyan like Baby Mario's. In the ''Yoshi'' series, he is depicted wearing only a white diaper and his green cap.

In his appearances in the ''Super Mario-kun'', Baby Luigi has big round eyes instead of his usual black beady eyes to fit in the artstyle of the rest of the ''Super Mario'' cast. To differentiate between Baby Mario, due to the lack of color in the manga itself, Baby Luigi's shirt is colored white while Baby Mario's shirt is colored black, similar to their adult counterparts. Baby Luigi also has a full set of teeth in the ''Super Mario-kun'' instead of having a single tooth as in the games.

===Personality===
[[File:Baby Luigi Artwork.png|thumb|100px|left|Baby Luigi is shown to be a very shy and meek character.]]
Baby Luigi, as his adult counterpart, is described as being meek and cowardly. For the most part, Baby Luigi is friendly and optimistic too, as he gets along well with the other babies. Baby Luigi's timid nature is also evidenced in the ''Mario Kart Wii'' official guide, which states that he used to ride with [[Baby Daisy]] until her boisterous nature scared him away. Games such as ''Mario Kart: Double Dash!!'' and ''Mario Superstar Baseball'' also depict Baby Luigi as a shy person, stating that his appearance in ''Double Dash!!'' is the first time he appears in front of a crowd. Baby Luigi also has an ability to sense danger; in ''Mario & Luigi: Partners in Time'', he was the only one who knew that Cobalt Star's spirit was actually the imprisoned the Elder Princess Shroob because he cried when he saw something in the Cobalt Star. He also hides from Bowser and Kamek as they attempt to locate the stars found in the star children. Although he is a crybaby, as seen in ''Partners in Time'', he seems to actually be a bit braver than his older self.

In the ''Super Mario-kun'' volumes that are adapted from ''Partners in Time'', Baby Luigi is portrayed as Baby Mario's cowardly, unwilling partner, and he often reacts to pressuring situations with shock and crying; the ''Super Mario-kun'' also frequently replicates Luigi's reactions with Baby Luigi's and vice-versa, used as a comedic feature to highlight the similarities of the two characters. Often times, when confronted by the Shroobs, he immediately bows down and surrenders, usually to find himself attacked by them shortly afterward; this is a running gag with the Luigi characters in the three ''Partners in Time'' volumes. He and Baby Mario are also able to speak. As with Baby Mario, he is shown to be very naive, and he and Baby Mario both undertake actions that can irritate their older selves. In volume 36 of the ''Super Mario-kun'', it is shown that Baby Luigi can be angered, to the point where it overtakes his normally passive reactions to stressful situations: he teams up with Baby Mario to use the Baby Drill as an attack against Mrs. Thwomp and the adult Mario Bros., he angrily pokes Baby Mario in the nose after a Tanoomba masquerading as Baby Mario pokes him in the nose, despite Baby Mario's confusion, and he was even about to furiously attack the Commander Shroob after he destroyed his rebuilt snowman, much to Baby Mario's surprise.

===Voice===
Baby Luigi has been portrayed by [[Charles Martinet]] (who also portrays his adult counterpart) starting with ''Mario Kart: Double Dash!!'', and has been portrayed by only Martinet ever since. Like Luigi, his voice often stammers and portrays timidity, nervousness, and uncertainty, but higher-pitched;<ref>{{cite|timestamp=7:07|author=GamerSpawn|date=September 10, 2011|url=youtu.be/r4Eudb_Tqg8|title=The Voice of Mario - Interview with Charles Martinet|publisher=YouTube|accessdate=September 26, 2014}}</ref><ref>{{cite|timestamp=0:49|author=SEAN LONG|date=September 6, 2013|language=en|url=youtu.be/bSZDEFbCc80?t=49|title=SacAnime 2013 Charles Martinet Voice Of Super Mario, Luigi & Wario Panel|quote=Oh wait I forgot about Baby Luigi...and Baby Mario, whoohoo!|publisher=YouTube|accessdate=June 30, 2024}}</ref><ref>{{cite|author=ShadowDragon28|date=September 3, 2013|timestamp=0:20|url=youtu.be/udKNIEW7bp0?t=20|title=Summer Sac-Anime 2013 Charles Martinet Panel (FRIDAY) - Part 1|quote=And Baby Luigi, oh mamma mia!|publisher=YouTube|accessdate=June 30, 2024}}</ref> he also occasionally speaks in third person, referring to himself as "Baby Luigi" rather than "Luigi". In ''Mario Kart 8'', Baby Luigi is generally higher-pitched than in preceding installments.

===Abilities===
Baby Luigi has very similar abilities to Baby Mario, except with some slight differences. They are both always lightweight characters in the ''Mario Kart'' series, they are always speed characters in the ''Mario Baseball'' series, and both have rivaling speed stats in ''Mario & Luigi: Partners in Time'', surpassing their adult counterparts' speed stats in the series. Baby Luigi, very much akin to his older self, however, is speedier than Baby Mario in most cases, often compromising power. In ''Partners in Time'', Baby Luigi is more defensively-oriented than Baby Mario, analogous to Luigi's stats compared to Mario. Baby Mario and Baby Luigi have a tendency towards Chain Chomps ever since it is portrayed as their special item in ''Mario Kart: Double Dash!!''; they are able to use the Pocket Chomp, which is an item exclusive to ''Partners in Time'' and combining the Baby Mario and Baby Luigi digital trading cards for a double play in ''Mario Super Sluggers'' unlocks a video titled, "Beware of the Chain Chomp".

===Relationships===
[[File:Daisy Circuit Statue MKWii babies.png|thumb|upright=0.8|A statue of Baby Luigi and Baby Daisy]]
[[File:BabyMarioBros - SuperMarioKun v35.png|thumb|left|Baby Mario and Baby Luigi together in volume 35 of the ''Super Mario-kun'']]
Baby Mario is Baby Luigi's older twin brother and best friend. Baby Mario and the Yoshis often work together to save Baby Luigi from Kamek in the ''Yoshi's Island'' games and, according to the second cinematic from ''Super Mario World 2: Yoshi's Island'', the bond between each other is strong enough to give Baby Mario the directions to rescue the captured Baby Luigi. In ''Mario & Luigi: Partners in Time'', the brothers team up for the duration of the game and are often interacting with each other. The two have good chemistry in ''Mario Superstar Baseball'' and its sequel ''Mario Super Sluggers''. In the ''Mario Super Sluggers'' challenge mode, Baby Luigi joins Mario and his adult self after informing them Baby Mario was locked in there by Bowser Jr. Lakitu then interprets Baby Luigi saying, "Aw, he wants to rescue Baby Mario. Brotherly love is a beautiful thing!" Baby Mario is also Baby Luigi's default partner in ''Mario Kart: Double Dash!!'' and the two go with each other to Mario and Luigi's tennis match in ''Mario Power Tennis''. They share a course in ''Double Dash!!'' and are portrayed together in ''Mario Kart Arcade GP 2''. Baby Luigi's site bio for ''Mario Kart Wii'', however, heavily implies that he has a sibling rivalry with Baby Mario, mirroring their adult selves' sibling rivalry.

Baby Luigi has good relationships with other babies, namely Baby Daisy; in ''Mario Kart Wii'', there is a statue of the two holding hands and dancing together on the [[Daisy Circuit]] course. The official guide for ''Mario Kart Wii'' also states that Baby Daisy used to ride with him until he got frightened of her rambunctious personality. In the first fight for the Baby Mario Bros. in ''Mario & Luigi: Partners in Time'', Baby Luigi is seen playing with Baby Peach, calming her down, while Baby Mario fights Baby Bowser.

[[File:LuigiBabyLuigi.png|200px|frame|Baby Luigi with his adult self]]
Baby Luigi and Luigi have also positive interactions with each other in ''Mario & Luigi: Partners in Time'', although Luigi is very forgetful, such as times when he leaves Baby Luigi behind during [[Petey Piranha]]'s arrival. He is very caring for Baby Luigi and usually calms him down when he is crying. A scene on Yoshi's Island in ''Partners in Time'' involves Luigi about to eat a cookie but he realizes Baby Luigi wants it. He decides to give the cookie to Baby Luigi, and Baby Luigi thanks him afterwards. At the end of the game, Baby Luigi is very reluctant to go back to the past and leave Luigi behind. When Baby Luigi finally decides to give in, he sends his hammer as a gift, as Baby Mario does to Mario, but humorously bonks Luigi on the head instead of simply giving it to him. However, Luigi's patience with the babies' antics is limited. When the adults fall in the [[Gritzy Caves]] and get knocked unconscious, the babies try to wake Luigi up, and when Baby Mario smacks him in the head with his hammer, Luigi gets mad and scolds them for the way they woke him up, but he accidentally causes them to cry and Mario scolds him after waking up to the babies crying.

Baby Luigi has been classified as a lightweight and speedy character in every game he is playable in. Bios typically highlight Baby Luigi's timid nature and his hostage role in the [[Yoshi's Island (series)|''Yoshi's Island'' series]]; he is often compared to his adult self. As Baby Luigi, some of his bios lampshade the fact that he and his adult self are playable alongside each other in the same game.
