'''Bullet Bills''' are [[List of enemies|enemies]] introduced in ''[[Super Mario Bros.]]'' These bullet-like projectiles are blasted out of [[Bill Blaster]]s, coupled with a firing sound effect, whether onscreen or offscreen. A Bullet Bill continues traveling horizontally when fired. Bullet Bills are unaffected by [[Fire Flower]]s and their [[fireball]]s, and most games allow Bullet Bills to be defeated from being [[stomp]]ed. In the side-scrolling games, Bullet Bills can pass through walls. Ever since ''[[Super Mario 64]]'', some Bullet Bills have the ability to home in on Mario as a missile, a function that would later go to [[Bull's-Eye Bill]]s mainly. Bullet Bills are portrayed as items in some series, mostly the [[Mario Kart (series)|''Mario Kart'' series]], functioning either as projectiles or having the player take advantage of their speed by either riding on them or transforming into one.

==History==
===''Super Mario'' series===
====''Super Mario Bros.'' / ''Super Mario Bros.: The Lost Levels''====
[[File:Bullet Bill Super Mario Bros.png|frame|left]]
[[File:SMB Bullet Bill Artwork.jpg|thumb|Artwork from ''Super Mario Bros.'', depicting the first design of a Bullet Bill]]
Bullet Bills are enemies in ''Super Mario Bros.'', ''[[Super Mario Bros.: The Lost Levels]]'', and their remakes within ''[[Super Mario All-Stars]]'' and ''[[Super Mario Bros. Deluxe]]''. Bullet Bills are usually shot from a [[Bill Blaster|Turtle Cannon]], though are sometimes shot from off-screen, and fly in a straight line. A Bullet Bill can be defeated if [[stomp]]ed or from the effects of a [[Super Star|Starman]]. A [[Koopa Shell]] or [[Buzzy Shell]] can defeat Bullet Bills instantly if they originate from off-screen, but not if they are shot from Turtle Cannons. Because Bullet Bills travel continuously, if Mario touches the [[Goal Pole|flagpole]], any Bullet Bills in his presence disappear instantly. Stomping on a Bullet Bill is always worth 200 points, and it is not possible to earn additional points by stomping them in succession. Bullet Bills and [[Piranha Plant]]s are the only two enemies with death animations that never depict them with their sprites flipped upside-down, the former remaining right side-up and the latter simply disappearing.

Bullet Bills are first encountered in [[World 5-1 (Super Mario Bros.)|World 5-1]] in ''Super Mario Bros.'' A Bullet Bill takes on the disguise of the [[fake Bowser]] in [[World C-4]]. Since Bullet Bills share the same color palette as Goombas, they appear gray in World 6-3 of ''Super Mario Bros.'' and blue in World A-2 from ''Super Mario Bros.: The Lost Levels''. Bullet Bills are not launched from the Turtle Cannons in [[World 9-1 (Super Mario Bros.: The Lost Levels)|World 9-1]] of ''Super Mario Bros.: The Lost Levels''.

====''Super Mario Bros. 3 / Super Mario Advance 4: Super Mario Bros. 3''====
Bullet Bills are enemies in ''[[Super Mario Bros. 3]]''. They are encountered mostly in [[airship]] stages. Besides previous methods, it is also possible for Bullet Bills to be defeated from a [[Hammer]], a [[Raccoon Mario|tail attack]], or a [[Bob-omb]] in certain stages. The game introduces [[Bull's-Eye Bill|Missile Bill]]s, which turn around and fly back towards Mario if it misses him the first time. The [[World-e]] level in ''[[Super Mario Advance 4: Super Mario Bros. 3]]'' features diagonally-fired Bullet Bills.

====''Super Mario Land''====
{{main|Bullet Biff}}
Bullet Bills do not appear in ''[[Super Mario Land]]'', but they were given variants named Bullet Biffs.

====''Super Mario World'' / ''Super Mario World: Super Mario Advance 2''====
[[File:BulletBill-SMW.png|frame]]
Bullet Bills are enemies in ''[[Super Mario World]]''. Bullet Bills are first encountered in [[Vanilla Dome 4]] where they are fired off-screen, while Bullet Bills emitted from Turtle Cannons are first encountered in [[Sunken Ghost Ship]]. Bullet Bills in [[Cheese Bridge Area]] are encountered in a zone led from a Warp Pipe. The level [[Outrageous]] includes several Bullet Bills launched from Turtle Cannons. The game introduces Bullet Bills that are fired diagonally from four corners, Bullet Bills shot vertically, and both the [[Torpedo Ted]] and [[Banzai Bill]] variants. Additionally, when the [[Special Zone]] is completed, horizontal-moving Bullet Bills turn into '''Pidgit Bills''', which function identically but look like flying [[Pidgit]]s. In ''[[Super Mario World: Super Mario Advance 2]]'', vertically and diagonally-fired Bullet Bills are given this design and are animated to flap their wings.

====''Super Mario Land 2: 6 Golden Coins''====
[[File:BulletBill-SML2.png|frame|left]]
Bullet Bills are enemies in ''[[Super Mario Land 2: 6 Golden Coins]]''. They often appear in the [[Mario Zone]]. Bullet Bills act like they do in previous games. Their design depicts them with grinning faces and no arms.

====''Super Mario 64'' / ''Super Mario 64 DS''====
{{multiframe
|[[File:Bullet Bill SM64.png|160px]][[File:SM64DS Bullet Bill WF.png|160px]]|Screenshot from ''Super Mario 64'' (left) and ''Super Mario 64 DS'' (right)|size=320
|align=right
}}
Bullet Bills are enemies in ''[[Super Mario 64]]'' and ''[[Super Mario 64 DS]]''. They are designed similarly to Banzai Bills. Bullet Bills are encountered in [[Whomp's Fortress]] only, after the [[Whomp King]] has been defeated, and are shot from Blaster at the top of the fortress. Bullet Bills home in on Mario and spin backwards upon contact, but explode after hitting a wall or after reaching a certain distance. Bullet Bills cannot be defeated, and any form of contact with it takes away three wedges of Mario's [[Health Meter|health]]. A Bullet Bill can appear from the blaster forcefully if Mario [[Ground Pound]]s it, though not in the remake.

In the remake, Bullet Bills can appear at the new base of Whomp's Fortress, directly opposite of the starting point. Bullet Bills were also added in [[Dire, Dire Docks]], at the submarine dock until completing [[Bowser in the Fire Sea]]. It was made possible to defeat a Bullet Bill from a [[kick]] or a [[Super Mushroom|Mushroom]], which sends them spinning backwards to eventually explode. The remake standardized the design of Bullet Bills, depicting them with smaller pupils, though their arms would be recolored from black to white in later appearances, matching their hands.

====''Super Mario Sunshine''====
[[File:Bullet Bill SMS.png|thumb|left|Artwork from ''[[Super Mario Sunshine]]'']]
Bullet Bills are enemies in ''[[Super Mario Sunshine]]''. They have been redesigned enitrely, having a metallic exterior, googly eyes, and smile in a manner akin to [[Torpedo Ted]]s. Bullet Bills make a quick radar beeping constantly as they fly. Bullet Bills appear with different colors and behaviors at various points in the game, coming in black, purple, [[Gold Bullet Bill|gold]], and blue. Most types of Bullet Bills release two [[coin]]s when squirted by [[F.L.U.D.D.|FLUDD]], except Golden Bullet Bills, which release eight coins instead. Black Bullet Bills are first shown at [[Pinna Park]] during [[Mecha-Bowser Appears!|Episode 1]], being fired from four cannons in [[Mecha-Bowser]]'s chest and following the tracks of the roller coaster that Mario is riding, either from the front or back, though they can still miss him by a wide margin on certain turns. In [[The Beach Cannon's Secret|Episode 2]], black, purple, and golden Bullet Bills appear fired by [[Monty Mole]], and all of them travel in a long, downward arc, exploding when they hit the ground, with black and gold only differing in rarity and coin reward. '''Purple Bullet Bills''',<ref name=prima>{{cite|author=Hodgson, David S J, Bryan Stratton, and Stephen Stratton|title=''Super Mario Sunshine'' Prima's Official Strategy Guide|publisher=Prima Games|page=19|date=September 3, 2002|language=en-us|isbn=0-7615-3961-1}}</ref> which have blinking red nosecones, follow Mario on a horizontal plane if they approach him, similarly to Bullet Bills in ''[[Super Mario 64]]'', though with a tight-but-lengthy u-turn if they miss; this type can destroy the baskets with [[Blue Coin]]s in the same [[Mission|episode]]. In [[Uncork the Waterfall|Episode 1]] of [[Noki Bay]], a single inactive black Bullet Bill is found laying dormant in the platform connecting the cannon to the giant cork. In the battle against [[Bowser]] and [[Bowser Jr.]] on [[Corona Mountain]], the latter shoots '''special Purple Bullet Bills'''<ref name=prima/> or '''Guided Bullet Bills''',<ref>{{cite|author=Bogenn, Tim, and Doug Walsh|title=''Super Mario Sunshine'' Official Strategy Guide|page=133|publisher=BradyGAMES|language=en-us|isbn=0-7440-0180-3|date=2002}}</ref> which come in black and blue, the former having a blinking nosecone (aside than the first one launched) and the latter being solid-colored. These ones follow Mario more persistently when they get a lock on him, but the large number causes them to have a fairly short and narrow line-of-sight, and they can also change their altitude to get on his level. These Bullet Bills can be defeated by jumped on, with the blue ones giving a [[1-Up Mushroom]] or [[Water Bottle]] if defeated this way, or from Bowser's [[Fire Breath]].

In the demo reel on the title screen, black Bullet Bills have blinking red noses and solid red eyes with white pupils, like Purple Bullet Bills, so the design change occurred most likely very late in development.

====''New Super Mario Bros.''====
Bullet Bills are enemies in ''[[New Super Mario Bros.]]'' Their role is based on their appearance from ''Super Mario Bros.'', except some of them are launched from [[Bill Blaster Turret]]s, and some can be additionally defeated from using a [[Mega Mushroom]]. [[Banzai Bill]]s also return as enemies. Bullet Bills are encountered in {{world-link|2|castlen|World 2-Castle (New Super Mario Bros.)}}; [[World 5-4 (New Super Mario Bros.)|World 5-4]], where some appear from offscreen; [[World 6-1 (New Super Mario Bros.)|World 6-1]]; {{world-link|6|castlen|World 6-Castle (New Super Mario Bros.)}}, during the [[Monty Tank]] fight only, [[World 7-5 (New Super Mario Bros.)|World 7-5]], and [[World 8-1 (New Super Mario Bros.)|World 8-1]]}}.

====''Super Mario Galaxy''====
[[File:SMG Bullet Bill.png|thumb|Artwork from ''Super Mario Galaxy'']]
Bullet Bills are enemies in ''[[Super Mario Galaxy]]''. They are very common and appear in several [[galaxy|galaxies]]. Upon being fired, if Bullet Bills notice the player character, their eyes turn red and they home in on him until hitting either him, an obstacle, or an enemy; this method can break open cages, destroy fences, and attack and eventually defeat [[Megaleg]] in [[Bowser Jr.'s Robot Reactor]]. If a Bullet Bill hits Mario, he is knocked down for a few seconds and loses a wedge of health. Both [[Banzai Bill]]s and [[Torpedo Ted]]s also make a reappearance.

====''New Super Mario Bros. Wii''====
Bullet Bills are enemies in ''[[New Super Mario Bros. Wii]]''. They act the same as in ''New Super Mario Bros.'', though they can be frozen by an [[Ice Ball]] from [[Ice Mario|Ice]] or [[Penguin Mario]]. Unlike other flying enemies, Bullet Bills could be picked up and thrown while frozen. They are encountered in [[World 3 (New Super Mario Bros. Wii)|World 3]]; [[World 5-5 (New Super Mario Bros. Wii)|World 5-5]], being fired from off-screen only; in [[World 6 (New Super Mario Bros. Wii)|World 6]], including as [[Enemy Course]]s; and in several levels of [[World 7 (New Super Mario Bros. Wii)|World 7]]. In addition to Missile Bills and Banzai Bills reappearing, the game also introduces [[King Bill]]s and [[Bull's-Eye Banzai|homing Banzai Bills]].

====''Super Mario Galaxy 2''====
[[File:MegaHammerBattle.png|thumb|left|Screenshot from ''Super Mario Galaxy 2'', showing Bullet Bills chase Mario and [[Yoshi]] in the battle against [[Megahammer]].]]
Bullet Bills are enemies in ''[[Super Mario Galaxy 2]]''. Several retain their homing capabilities, though some Bullet Bills in [[Bowser Jr.'s Fearsome Fleet]] and [[Bowser's Galaxy Generator]] fly straight and do not follow the player character. [[Yoshi]] can use his tongue to capture an incoming Bullet Bill in his mouth and spit it back out at other incoming enemies or bosses; this is required to attack and eventually defeat [[Megahammer]], which launches out Bullet Bills constantly. Banzai Bills also return as enemies.

====''Super Mario 3D Land''====
[[File:SM3DL Bullet Bill.PNG|thumb|Screenshot from ''Super Mario 3D Land'', showing Bullet Bills in [[World 2-Airship (Super Mario 3D Land)|World 2-Airship]]]]
Bullet Bills are enemies in ''[[Super Mario 3D Land]]''. This is the first 3D game where Bullet Bills travel in only a single direction and to have [[stomp]]ing or a [[boomerang]] as a method for defeating them. A Bullet Bill that is tail-whipped by [[Tanooki Mario]] changes its angle after a spin and keeps flying. The game introduces [[Tail Bullet Bill]]s, which are Bullet Bills that have striped tails.

====''New Super Mario Bros. 2''====
Bullet Bills are enemies in ''[[New Super Mario Bros. 2]]''. They retain their traits from before. While a [[Gold Ring]] is active, Bullet Bills become [[Gold Bullet Bill|golden]] and leave a trail of coins behind them. Jumping on the Bullet Bills themselves discontinue the production of any more coins. Exclusively in the course packs [[Coin Challenge Pack B]] and [[Platform Panic Pack]] are diagonally flying Bullet Bills.

====''New Super Mario Bros. U''====
Bullet Bills are enemies in ''[[New Super Mario Bros. U]]''. They act similarly as before, though produce a red smoky flare like in ''Super Mario 3D Land''. Bullet Bills also appear in the battle against [[Roy|Roy Koopa]], who shoots them from a Bill Blaster at players. Besides the returning [[Torpedo Ted]]s from ''Super Mario World'', Bullet Bills also have a variant named [[Targeting Ted]]s.

====''Super Mario 3D World'' / ''Super Mario 3D World + Bowser's Fury''====
[[File:BulletBillSM3DW.jpg|thumb|Screenshot from ''Super Mario 3D World'', showing Bullet Bills being launched]]
Bullet Bills are enemies in ''[[Super Mario 3D World]]'' and ''[[Super Mario 3D World + Bowser's Fury]]''. They act the same as before. The game introduces a [[Cat Bullet Bill]] based on the [[Cat Mario]] transformation that is based on the Tail Bullet Bills in ''Super Mario 3D Land''.

====''Super Mario Maker'' / ''Super Mario Maker for Nintendo 3DS''====
[[File:Img mashiko 02.gif|thumb|left|Artwork from ''Super Mario Maker'', showing [[Mary O.]] hammer a loose nail on a [[Bill Blaster]]]]
Bullet Bills are enemies in ''[[Super Mario Maker]]'' and ''[[Super Mario Maker for Nintendo 3DS]]''. They are not standalone enemies, since they emerge from Bill Blasters only. Likewise, [[Bull's-Eye Bill]]s return, and they are fired from [[Bull's-Eye Blaster]]s.
{{br}}

====''Super Mario Run''====
Bullet Bills are enemies in ''[[Super Mario Run]]''. They are encountered in the levels [[Sky-High Lifts and Leaps!]] and [[Bullet Bill Barrage]]. Bullet Bills behave the same as before, other than the fact that all of them are launched offscreen. Bull's-Eye Bills also make a returning appearance.

====''Super Mario Odyssey''====
[[File:SMO Art - E3 Char7.png|thumb|Artwork from ''Super Mario Odyssey'' of a captured Bullet Bill]]
Bullet Bills are enemies ''[[Super Mario Odyssey]]''. They are encountered in the [[Metro Kingdom]] and the [[Sand Kingdom]], where they wear visors, as well as in the [[Underground Moon Caverns]] in the [[Moon Kingdom]], where they wear white top hats. Bullet Bills chase after Mario upon being fired from a Bill Blaster. If the Bullet Bill cannot see Mario, usually because he is inside a two-dimensional area and the Bullet Bill is not, the Bullet Bill just flies forward. They explode on contact with anything, including other Bullet Bills. This can break certain [[Block (Super Mario Odyssey)|Blocks]] or interact with a number of objects. They start to glow red if they fly for too long, which signifies that the Bullet Bill will explode on its own soon. Bullet Bills can also appear in two-dimensional areas, using their sprite from ''Super Mario Bros.''. They function as they do in that game, but still explode on contact with any surface. Bullet Bills are allowed to fly into and out of two-dimensional areas, with their behavior changing as part of the swap.

A Bullet Bill can be [[capture]]d temporarily, first by using the [[Cap Throw]] to knock off its hat and then using the Cap Throw a second time. As a captured Bullet Bill, Mario can travel across [[pit]]s. The player can accelerate with {{button|switch|Y}} or {{button|switch|X}}, causing purple flames to erupt from the Bullet Bill as it flies faster. Shaking the controller has the Bullet Bill twirl, increasing the speed further. Mario cannot change elevation. Between capturing the Bullet Bill and starting to fly, the player can rotate the Bullet Bill in any direction. Bullet Bills continue to explode on contact with anything or when their timer elapses, though this does not harm Mario and is easier to direct to the player's advantage since the Bullet Bill is being guided. The timer for exploding is reset when a Bullet Bill is captured for the first time. In dark areas, the eyes of a captured Bullet Bill are flashlights, illuminating the area in front of it and showing where Mario is  After being released, a Bullet Bill is not stunned. A second timer is set, and the Bullet Bill flies forward instead of chasing Mario until that timer runs out. 

Banzai Bills appear much later in the game, functioning similarly to Bullet Bills but with an immunity to Blocks and enemies. [[Knucklotec]], a boss in the Sand Kingdom, has two floating hands each named Kuncklotec's Fist. They can be captured, and control identically to Bullet Bills. The hands do not explode, but are still timed.

====''Super Mario Maker 2''====
Bullet Bills are enemies in ''[[Super Mario Maker 2]]''. Their role is similar as in ''Super Mario Maker'', but in the added ''Super Mario 3D World'' style, Bullet Bills can defeat enemies on contact and get defeated when hitting a wall; version 3.0.0 introduces the [[Bullet Bill Mask]] in said style.

====''Super Mario Bros. Wonder''====
[[File:SMBW screenshot Blasted Bill.png|thumb|A Missile Meg under the effect of a [[Wonder Flower]]]]
Bullet Bills are enemies in ''[[Super Mario Bros. Wonder]]''. A few variants were introduced, all prominently in [[Castle Bowser]] levels: [[Missile Meg]]s, which bear a vicious grimace and a more elongated shape resembling a missile and can be stood upon; [[Seeker Bullet Bill]]s, which stick onto surfaces and fly towards the players on contact; and [[Renketsu Search Killer]]s, variants of Bull's-Eye Bills consisting of multiple segments and dorsal fins.

===''Alleyway''===
[[File:Stage15 Alleyway.png|thumb|left|The Bullet Bill block formation in stage 15 of ''[[Alleyway]]'']]
Several breakable blocks are arranged in the shape of a Bullet Bill in stage 15 of ''[[Alleyway]]''.

[[File:CartoonBill.jpg|thumb|Three Bullet Bills from ''The Super Mario Bros. Super Show!'' episode "[[Robo Koopa (episode)|Robo Koopa]]"]]
Bullet Bills appear only in "[[Robo Koopa (episode)|Robo Koopa]]" of ''[[The Super Mario Bros. Super Show!]]'', though Bullet Bill-like projectiles with gray bodies, peach-colored arms, and toothy grins are fired by a Snifit in "[[On Her Majesty's Sewer Service]]."

====''The Adventures of Super Mario Bros. 3''====
[[File:BulletBillTAOSMB3.png|200px|thumb|left|Three Bullet Bills from ''The Adventures of Super Mario Bros. 3'' episode "[[Mush-Rumors]]"]]
Bullet Bills appear only in "[[Reptiles in the Rose Garden]]" and "[[Mush-Rumors]]" of ''[[The Adventures of Super Mario Bros. 3]]''. They are projectiles fired from the [[Bowser's Airship|Doom Ship]]. Additionally, they are launched at a family consisting of [[Norman]], [[Bud and Missy's mother|his wife]], [[Missy]], and [[Bud]] in "Mush-Rumors."

===''Nintendo Comics System''===
In the ''[[Nintendo Comics System]]'' story "[[The Kingdom Enquirer]]", several Bullet Bills (depicted as being able to talk) appear among the various monsters pestering [[Toad]] (who had become a reporter) for an interview. A later story, entitled "[[Bowser Knows Best]]", also features Bullet Bills, who the [[Koopalings]] hitch a ride on in order to chase down [[Princess Peach|Princess Toadstool]], who had previously escaped their clutches.

===''Super Mario Adventures''===
In ''[[Nintendo Power]]''{{'}}s ''[[Super Mario Adventures]]'' comic, a Bullet Bill makes a relatively small appearance; after accidentally activating a Turtle Cannon after knocking Luigi off it, Mario is blasted by a Bullet Bill, which he ends-up riding straight into the Koopaling's Tower, where he is captured by Bowser's forces.

===''Mario Kart'' series===
Bullet Bills<ref>{{cite|language=ja|title=「VSマッチ専用の敵キャラ、キラー。ヤツが勝敗を決めることも。」Nintendo Official Guidebook of ''Super Mario Kart''|page={{file link|SMK NOG Killer.png|126}}}}</ref> appear as both obstacles and items in the [[Mario Kart (series)|''Mario Kart'' series]].

====''Super Mario Kart''====
{{multiframe|[[File:SMK Bullet Bill.png]]|size=130|A Bullet Bill in ''Super Mario Kart''}}
Bullet Bills are obstacles in ''[[Super Mario Kart]]''. They appear in Match Race, functioning as additional obstacles in all Mario Circuit courses, Donut Plains courses (excluding [[SNES Donut Plains 3|Donut Plains 3]]) and Bowser Castle courses. They bounce back and forth between two walls, and racers that come into contact with them spin out and cause it to bounce off the screen.

====''Mario Kart DS''====
[[File:MKDS Bullet Bill Artwork.jpg|thumb|left|A Bullet Bill in ''Mario Kart DS'', its first appearance as an item]]
Bullet Bills are obstacles and an item in ''[[Mario Kart DS]]''. As obstacles, Bullet Bills are depicted with their arms flattened to their sides, and they appear in [[DS Airship Fortress|Airship Fortress]] only. As an item, Bullet Bills are received by players in 6th place or lower. When activated, the user's entire [[kart]] briefly transforms into an invincible Bullet Bill, which rockets down the track at high speed, mostly in auto-pilot, but the player still has a little bit of steering control. Any driver or obstacle hit by a Bullet Bill, whether it is an item or an obstacle, is knocked out of the way and drops any item in their possession, a function derived from the [[Chain Chomp]] item in ''[[Mario Kart: Double Dash!!]]''. A Bullet Bill cannot damage players under the effects of a [[Super Star|Star]] or a [[Boo]], though the former condition still knocks them aside slightly. Players using a Bullet Bill cannot receive any items from an [[Item Box]]. The Bullet Bill item has a longer duration, the lower ranked a player is.

====''Mario Kart Wii''====
[[File:MKW Bullet Bill Screenshot.png|thumb|Wario using a Bullet Bill]]
Bullet Bills are items in ''[[Mario Kart Wii]]''. They can be received only by players in 8th place or lower, most commonly in 12th place, which has a 25% chance. Bullet Bills function identically as in ''Mario Kart DS'', though players under the effects of a [[Mega Mushroom]] can also be knocked back by this item. When a Bullet Bill is used, another one cannot be obtained until the current one is exhausted, much like the [[Thunder Cloud]], [[Spiny Shell (blue)|Spiny Shell]], [[Blooper]], [[POW Block]], and [[Lightning]]. A Bullet Bill is the basis for the design of the [[Bullet Bike]].

====''Mario Kart 7''====
Bullet Bills are items in ''[[Mario Kart 7]]''. They function similarly as in ''Mario Kart Wii'', but can be received by players only in 6th place or lower. Bullet Bills now slow before expiring, reducing the likelihood of players falling off the course. The warning sound from ''Mario Kart Wii'' also plays when a Bullet Bill is nearby.

====''Mario Kart Arcade GP DX''====
Bullet Bills make a cameo appearance in ''[[Mario Kart Arcade GP DX]]'', where in one of the courses they fly overhead as the player approaches the finish line. However, they do not affect gameplay.

====''Mario Kart 8'' / ''Mario Kart 8 Deluxe''====
Bullet Bills are items in ''[[Mario Kart 8]]'' and [[Mario Kart 8 Deluxe|its port]]. They also have their own sponsor, [[Bullet Bill Speed Trial]]. A Bullet Bill's eyes glow in the dark in [[Twisted Mansion]] and other dark areas. Originally, the rear-view mirror is not usable while using a Bullet Bill, though this was changed as of version 2.3.0 of ''Mario Kart 8 Deluxe''. Players who can receive a Bullet Bill have to be a certain distance from the player in first place. Up to three Bullet Bills can be used on a course at once.

====''Mario Kart Tour''====
Bullet Bills are items in ''[[Mario Kart Tour]]''. During a Bullet Bill [[Frenzy]], two smaller Bullet Bills fly beside the player. The player can launch said Bullet Bills forwards by tapping the screen, which home in on a racer ahead of them, and explode upon striking them. There is also a new glider introduced in the [[Bowser vs. DK Tour]] that is a recreation of the Bullet Bill's appearance in ''Super Mario Bros.'', aptly named [[8-Bit Bullet Bill]].

The following gliders increase the chance of getting Bullet Bills and points for hitting racers under the effects of one.

===''Super Mario Bros.'' film===
[[File:BulletBillCartridge.jpg|thumb|Bullet Bill prop used in the film.]]
In the 1993 ''[[Super Mario Bros. (film)|Super Mario Bros.]]'' film, miniature, non-explosive Bullet Bills appear as the fuel cartridges of the [[Thwomp Stomper]]s used by [[Mario (film character)|Mario]], [[Luigi (film character)|Luigi]] and [[Big Bertha (film character)|Big Bertha]]. A neon sign advertising a bar called "Bullet Bill's" can also be seen prominently displayed in the [[Koopa Square]] in [[Dinohattan]] throughout the film. [[Princess Daisy (film character)|Daisy]] can be seen wearing various Bullet Bills in the film's ending when she interrupts Mario, Luigi and [[Daniella]]'s meal.

Though they are officially meant to be Bullet Bills, they more resemble [[Banzai Bill]]s; an earlier draft of the script more appropriately referred to these cartridges as "Banzai Bills".<ref>{{cite|url=www.nintendoplayer.com/feature/super-mario-bros-movie|title=Fungus Among Us: Super Mario Bros.

===''Yoshi's Safari''===
Bullet Bills are enemies in ''[[Yoshi's Safari]]''. They arrive from offscreen and can be destroyed from a single hit with the [[Super Scope]]. They are seen from the front only like in ''Super Mario Kart''.

===''Mario's Time Machine''===
[[File:Bullet Bill MTMDX.png|frame]]
Bullet Bills are enemies in the PC release of ''[[Mario's Time Machine (PC)|Mario's Time Machine]]'' only. They appear if [[Mario]] sets the date on the [[Timulator]] incorrectly, sending him to the prehistoric era. Here, Bullet Bills fly at Mario from offscreen while he collects eggs from a [[pterodactyl]]. A Bullet Bill can be jumped over automatically if Mario approaches it, though if a Bullet Bill hits Mario, he loses an egg.

===''Yoshi's Island'' series===
[[File:BulletBill-SMW2.png|frame|left]]
Bullet Bills are enemies in ''[[Super Mario World 2: Yoshi's Island]]''. They are colored green instead of black and have facial expressions. The game introduces [[Bouncing Bullet Bill]]s, which bounce and ricochet off walls after being fired. The [[Yoshi's Island: Super Mario Advance 3|remake]] also adds [[Bull's-Eye Bill|Missile Bill]]s, which home in on Yoshi while biting upon being shot out of their cannons. Bullet Bills can be defeated through the same methods as most enemies. If Yoshi catches a Bullet Bill with his tongue, it can be spit out and flies away from Yoshi like it has been shot out of a cannon, or Yoshi can eat one to produce an egg.

During ''Super Mario World 2: Yoshi's Island''{{'}}s development, the Bullet Bill was colored its usual black and was intended to bite as it moved.<ref>{{cite|author=TCRF|title=[[tcrf:Development:Super Mario World 2: Yoshi's Island/Sprites#killer.CGX|Development:Super Mario World 2: Yoshi's Island/Sprites#killer.CGX]]|publisher=The Cutting Room Floor|accessdate=November 12, 2021|language=en}}</ref>

Bullet Bills return in the sequel, ''[[Yoshi's Island DS]]'', where they were changed to black to be consistent with their appearance in ''Super Mario'' games. Bullet Bills also return in ''[[Yoshi's New Island]]'', performing the same actions as in previous ''Yoshi's Island'' games and retaining their design from games in the ''Super Mario'' series, like with ''Yoshi's Island DS''.

===''Super Mario RPG: Legend of the Seven Stars''===
[[File:SMRPG BulletBill.jpg|thumb|100px|left|A Bullet Bill as it appears in ''Super Mario RPG: Legend of the Seven Stars'']]
In ''[[Super Mario RPG: Legend of the Seven Stars]]'', [[Apprentice (Snifit)|Apprentice]]s, [[Snifster]]s, [[Bill Blaster|Blaster]]s, and [[Big Blaster]]s use Bullet Bills as a way to attack. Usually, touching one in the overworld prompts a battle with Blasters or Big Blasters, though a room in the [[Sunken Ship]] has them shot by normal [[cannon]]s and simply push Mario to a lower floor. This game also introduces [[Blazer]]s, an alternate variety of Bullet Bills, which are used by Blasters and Big Blasters to defeat a party member in one hit and cannot be blocked. [[Smithy]] uses a similar variety called [[Magnum]]s.

In [[Super Mario RPG (Nintendo Switch)|the remake]], Bullet Bills retain their original design, having arms and a mouth.

[[File:BulletBillYS.gif|frame|left]]
Bullet Bills are enemies in ''[[Yoshi's Story]]''. They follow the same pattern as before, though the game introduces tongues for the mechanical irritants. The Blasters of this game are slightly different in appearance and the Bullet Bills are golden in color.

===''Super Smash Bros.'' series===
{{main-wiki|SmashWiki|Bullet Bill}}
[[File:SSB Bullet Bill model.png|thumb|64px|In ''Super Smash Bros.'']]
Bullet Bills first appear in ''[[Super Smash Bros.]]'' One of {{iw|smashwiki|Master Hand}}'s attacks firing pairs of Bullet Bills from his fingers, though later games replace them with regular bullets. The Bullet Bills shot by Master Hand are gold and resemble their design in ''Yoshi's Story''.

''[[Super Smash Bros. Melee]]'' is the only ''Super Smash Bros.'' game where Bullet Bills do not appear. However, the [[Trophy (Super Smash Bros. series)|trophy]] of the Banzai Bill enemy from [[Princess Peach's Castle (Super Smash Bros. Melee)|Princess Peach's Castle]] erroneously identifies it as "Bullet Bill" when the language is set to English. This was fixed in later NTSC revisions and the PAL version to match the Japanese text.
[[File:Bullet Bill SSB4 3DS.jpg|thumb|left|The Bullet Bill enemy in ''Super Smash Bros. for Nintendo 3DS'']]
Bullet Bills have appeared in a few of the series' single-player campaigns. In ''[[Super Smash Bros. Brawl]]'', Bullet Bills are enemies in [[smashwiki:Adventure Mode: The Subspace Emissary|The Subspace Emissary]], where they are affiliated with Bowser's forces and the [[smashwiki:Subspace Army|Subspace Army]]. Here, Bullet Bills launch straight from right to left, like with most of their appearances in the ''Super Mario'' franchise, although they appear larger than in most of their other appearances and cannot be stomped on. Bullet Bills do sometimes home in on the character, similarly to [[Bull's-Eye Bill]]s, and can be temporarily deflected. In a cutscene, silver Bullet Bills are seen pursuing [[Diddy Kong]] and [[Donkey Kong]], but explode after being defeated by the [[Kong]]s' attacks. In ''[[Super Smash Bros. for Nintendo 3DS]]'', Bullet Bills are an enemy in the [[smashwiki:Smash Run|Smash Run]] mode, where they slowly fly toward the player to try and hit them and inflict damage.
[[File:SSB4 WiiU BulletBill Item.jpg|thumb|The Bullet Bill item in ''Super Smash Bros. for Wii U'']]
In ''Super Smash Bros. for Nintendo 3DS'' / ''[[Super Smash Bros. for Wii U|Wii U]]'' and ''[[Super Smash Bros. Ultimate]]'', Bullet Bills are also featured as an item. When a player picks up a Bullet Bill, they attack by ramming into opponents at full speed. Players explode if they hit a solid wall, including ceilings and floors, and the resulting explosion deals even further damage to players and has a blast radius.

In ''Super Smash Bros. Ultimate'', in addition to returning as items, a Bullet Bill also appears as one of the drawings drawn by [[smashwiki:Nikki|Nikki]]. After it is fully drawn, it launches off, damaging any opponent in its path. A Bullet Bill also appears in the game as a Novice-class Attack-type {{iw|smashwiki|primary spirit}}. Once it reaches level 99, it can be enhanced to a [[Banzai Bill]]. In [[smashwiki:Adventure Mode: World of Light|World of Light]], the [[Spirit (Super Smash Bros. Ultimate)|spirit]] is encountered on {{iw|smashwiki|The Light Realm}} map; the puppet fighters are four small {{iw|smashwiki|Captain Falcon (SSBU)|Captain Falcons}} fought on the [[Mushroom Kingdom (Super Smash Bros.)|Mushroom Kingdom]] stage, with Bullet Bill items spawning throughout the battle.

===''Mario Party'' series===
====''Mario Party 2''====
Bullet Bills are obstacles in the minigame [[Bombs Away (minigame)|Bombs Away]] in ''[[Mario Party 2]]''. They are fired from a Bowser ship and hit the island eventually, forcing players to time their jumps right to avoid being stunned by the explosion.

====''Mario Party 3''====
Bullet Bills are an interactable species in ''[[Mario Party 3]]''. They are obstacles in the minigames [[Crazy Cogs]] and [[Ridiculous Relay]], usable weapons in [[Aces High]], and cameo in [[Pump, Pump and Away]].

====''Mario Party 5''====
Bullet Bills are usable weapons in the minigame [[Bill Blasters (minigame)|Bill Blasters]] and items in ''[[Mario Party 5]]''.

====''Mario Party 6''====
Bullet Bills are non-playable characters and items in ''[[Mario Party 6]]''. As items, Bullet Bill Orbs have the same effect, except they steal only 20 coins per opponent instead. The minigame [[Jump the Gun]] involves a player shooting Bullet Bills at targets to form a platform for their partner. In [[Shoot Yer Mouth Off]] minigame, saying 4, 8, or 9 shoots a Bullet Bill, eliminating a rival player on contact, as well as the "Bullet Bill" voice in [[Verbal Assault]], though the latter can be unlocked from the Star Bank. The [[Magma Flow]] path in [[Star Sprint]] also has Bullet Bills being shot at the player.

====''Mario Party Advance''====

{{quote|Hey, stay outta my way! I'm trainin'! Don't you know who I am? I'm Bullet Bill!|Bullet Bill|[[Mario Party Advance]]}}
A Bullet Bill is a character in ''[[Mario Party Advance]]''. He is a track and field athlete at the [[Mushroom Stadium]]. He is also a huge fan of the [[Kamek Krew]], owning all of their albums and even letting them perform at his stadium. For his quest, Bullet Bill can be raced by the player, and defeating him causes the player to be handed over the [[Mini Soccer]] [[Gaddget]]. In a separate quest, Bullet Bill is hesitant to rent out his stadium, but he eagerly obliges when he is told it is the [[Kamek Krew]], of which he is a big fan. Bullet Bill allows the Kamek Krew to perform there free of charge and begins the preparations. Some time later, Bullet Bill finished second in the world sprint trials.<ref>{{cite|quote=Finished second in the world sprint trials.|author=Bullet Bill|title=''Mario Party Advance''|publisher=Nintendo|language=en|date=2005}}</ref>

Bullet Bills are obstacles in the minigame [[Bill Bounce]]. It involves jumping on Bullet Bills to earn points, with more being earned from jumping on several in succession. If a Bullet Bill hits the player, they are stunned temporarily.

====''Mario Party 7''====
Bullet Bills are obstacles in the [[Wheel of Woe]], [[StratosFEAR!]], and [[Helipopper]] minigames of ''[[Mario Party 7]]''. A character hit by a Bullet Bill in any of the minigames loses. In Wheel of Woe, saying a Bullet Bill's name summons two Bullet Bills out of blasters on each side of the room at the other three players.

====''Mario Party 8''====
[[File:MP8 Red Bullet Bill.png|thumb|left|Screenshot from ''Mario Party 8'', showing Bullet Bills in Superstar Showdown]]
Bullet Bills are obstacles in the minigames [[Sick and Twisted]] and [[Thrash 'n' Crash]], weapons in [[Cardiators]], and items in ''[[Mario Party 8]]''. As an item, Bullet Bills appear in the form of [[Bullet Candy]], exclusively in [[Bowser's Warped Orbit]], which transforms the lower half of the user into a blaster; allows them to hit three [[Dice Block]]s; and steal one Star from each opponent run into. In Sick and Twisted, even jumping on a Bullet Bill eliminates the character. Cannons in the second stage of [[Superstar Showdown]] shoot black Bullet Bills, after attaching to Bowser's Clown Car, and red Bullet Bills during the third stage, both types steering themselves at the player slightly. The minigame [[Gun the Runner]] has a helicopter that the team of three are in while up against the solo player. Three Bullet Bills are used in Cardiators if the player gets a card with three Bullet Bills, firing at the opponent and dealing nine damage upon them in total.

===''Paper Mario'' series===
====''Paper Mario''====
[[File:PMBulletBill.png|thumb]]
Bullet Bills are enemies in ''[[Paper Mario]]''. They are encountered in the [[Koopa Bros. Fortress]], being shot out by Bill Blasters shortly before the [[Koopa Bros.]] are fought. They attack by ramming into Mario, destroying themselves in the process. If a Bullet Bill bumps into Mario on the overworld, it makes the [[First Strike]] on him.

Gold Bullet Bills known as [[Bombshell Bill]]s are also introduced in ''Paper Mario'' and are shot from [[Bombshell Bill Blaster|B. Bill Blaster]]s. They are found in [[Bowser's Castle]]. These attack the same way as regular Bullet Bills, but they have more HP, do more damage, and have 1 defense.
{{br|left}}

====''Paper Mario: The Thousand-Year Door''====
[[File:PMTTYD Bullet Bill Sprite.png|thumb|40px]]
Bullet Bills are enemies in ''[[Paper Mario: The Thousand-Year Door]]''. They are encountered in [[Pirate's Grotto]], where they are once again shot by [[Bill Blaster]]s. Bombshell Bills and their Blasters also appear in the [[Palace of Shadow]]. Bullet Bills home in on Mario to damage him, destroying themselves by doing so. Because of this, they also die if they miss or are [[Superguard]]ed.
{{br|right}}

====''Super Paper Mario''====
[[File:PMTTYD Bullet Bill Sprite.png|thumb]]
Bullet Bills are enemies in ''[[Super Paper Mario]]''. They appear once in [[The Bitlands]]. There are two Bill Blasters mounted on each of the fortresses that continuously shoot them—however, if the player returns to the chapter after completing it, there is only one; the other is mounted on the fortress that gets destroyed. A simple stomp destroys them. The player can also use [[Thoreau]] to pick up the Bullet Bill and throw it at the Bill Blaster.

====''Paper Mario: Sticker Star''====
[[File:PMSSBulletBillSprite.png|thumb]]
Like with the previous game, Bullet Bills only appear in one level, [[Bowser Jr.'s Flotilla]], in World 6 in ''[[Paper Mario: Sticker Star]]''. In this level, there are two Bill Blasters mounted at the platforms on the airship's exterior. However, unlike previous iterations, they cannot be battled; instead, they fly at Mario and damage him upon contact. They can be defeated by hammering them or jumping on them. Touching a Bullet Bill causes Mario to lose 2 [[Heart Point|HP]]. They were originally able to be battled, as evidenced by the text dump.<ref>{{cite|url=tcrf.net/Paper_Mario:_Sticker_Star#Enemies|title=''Paper Mario: Sticker Star'' § Enemies|publisher=The Cutting Room Floor|accessdate=November 12, 2018|language=en}}</ref>

===''Mario Golf'' series===
Bullet Bills are non playable characters in the ''[[Mario Golf (series)|Mario Golf]]'' series. They are shot out of Bill Blasters resembling the Monty Mole's cannons from ''Super Mario Sunshine'' atop towers in ''[[Mario Golf: Toadstool Tour]]''. They land into the water but have no effect on gameplay. Bullet Bills are usable item shots in ''[[Mario Golf: World Tour]]'', increasing the player's maximum driving distance and causing the ball to travel in a straight line, ignoring wind and player stats. Bowser Jr. rides a Bullet Bill for his [[Special Dash]] in ''[[Mario Golf: Super Rush]]''.

===''Mario & Luigi'' series===
[[File:Sniper Bill.png|thumb]]
====''Mario & Luigi: Superstar Saga'' / ''Mario & Luigi: Superstar Saga + Bowser's Minions''====
Bullet Bills are obstacles in ''[[Mario & Luigi: Superstar Saga]]'' and ''[[Mario & Luigi: Superstar Saga + Bowser's Minions]]''. They are launched from Bill Blasters in [[Stardust Fields]] at Mario and Luigi to attack, which can be dodged or [[Counterattack|countered]] with a jump. [[Mecha-Blooper]]s, which are found in the [[Seabed]] and [[Gwarhar Lagoon]], also use Bullet Bills to attack. The game also features a new subspecies called the [[Sniper Bill]], a Bullet Bill that uses a [[Super Scope]] as a weapon which fires a smaller Bullet Bill. It is found in [[Bowser's Castle]]. In the original version, landing on the Sniper Bill after jumping causes no damage.

====''Mario & Luigi: Partners in Time''====
[[File:ML2 Elite Boom Guy.PNG|left|frame]]
In ''[[Mario & Luigi: Partners in Time]]'', two variants of [[Shy Guy]] called [[Boom Guy]]s and [[Elite Boom Guy]]s carry Bill Blasters on their head. They run up to the Mario Bros. and shoot out a Bullet Bill to harm them. Sometimes, the cannon lets out a little puff before firing the Bullet Bill. Energy-based ones can also be spotted during the boss fight against [[Swiggler]] in the [[Vim Factory]], if the player looks closely when the [[Shroob saucer]]s attack.

====''Mario & Luigi: Bowser's Inside Story'' / ''Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey''====
[[File:MLBISBJJDarkMinions.png|thumb]]
Bullet Bills are enemies in ''[[Mario & Luigi: Bowser's Inside Story]]'' and ''[[Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey]]''. They are shot out of cannons manned by [[Air Cannon]]s, after which Bullet Bills may turn invisible and attack one of the Mario Brothers, who can dodge with precise timing. During the final battle with [[Dark Bowser]], dark versions of Bullet Bills are among those which appear during his dark minion attack. Bowser must punch the Bullet Bills or duck under them depending on their height.

====''Mario & Luigi: Paper Jam''====
While Bullet Bills themselves do not appear in ''[[Mario & Luigi: Paper Jam]]'', there are [[papercraft]] versions of Bullet Bills that appear during the Papercraft Bowser segment.

===''WarioWare'' series===

In ''[[WarioWare: Twisted!]]'', Bullet Bills make appearances with their ''[[Super Mario Bros. 3]]'' sprites in the microgame [[Super Mario Bros. 3 (lift microgame)|Super Mario Bros. 3-Lift]], a ''Super Mario Bros. 3''-based microgame found in [[9-Volt]] and [[18-Volt]]'s stage, where they appear as one of the enemies that the player has to avoid. They also make cameos in ''[[WarioWare: Touched!]]'' in two microgames: in the [[Super Mario Bros. (Stomp!)|Super Mario Bros.]] ''Stomp!'' microgame, where in the third level, when the player defeats all the enemies, Mario appear riding in a Bullet Bill instead of in a Lakitu's Cloud, and in the microgame [[Clawing for More (WarioWare: Touched!)|Clawing for More]], where they appear as one of the sprites that can appear when the player grabs the ball. Bullet Bills return in the [[Super Mario Bros. 3 (lift microgame)|Super Mario Bros. 3]] microgame in ''[[WarioWare Gold]]''.

===''Mario Tennis'' series===
Bullet Bills make a few appearances in the [[Mario Tennis (series)|''Mario Tennis'' series]]. In ''[[Mario Power Tennis]]'', near the climax of the opening cinematic, Bowser launches a Bullet Bill from his balloon, only for Mario to knock it away with his tennis racket, striking Wario and Waluigi, and the Special Game [[Mecha-Bowser Mayhem]] features Bullet Bills launched by [[Mecha-Bowser]]. In ''[[Mario Tennis Aces]]'', Bullet Bills appear in the adventure mode level [[Defeat Bowser's Minions!]], found at the Castle Gates. They are fired from two Bill Blasters when the player battles a [[Whomp]], and can be blocked by Mario's tennis racket to cause them to damage the Whomp. Getting hit by a Bullet Bill causes Mario to lose ten seconds on the timer.

===''Mario Baseball'' series===
[[File:Mss hrc bowser.png|thumb|Screenshot from ''Mario Super Sluggers'' of Bowser hitting a Bullet Bill during the last cutscene]]
Bullet Bills are non-playable characters in the [[Mario Baseball (series)|''Mario Baseball'' series]]. Their role is largely similar between ''[[Mario Superstar Baseball]]'' and ''[[Mario Super Sluggers]]''. In both games, Bowser uses the Bullet Bill for pitching in his [[Star Skill]], [[Killer Ball]], as well as for batting in ''Mario Superstar Baseball''; similarly, a Bullet Bill wearing a bandana resembling [[Bowser Jr.]]'s is used by said character when using [[Killer Jr. Ball]] in ''Mario Superstar Baseball'' only. While pitching, a Bullet Bill is launched at the batter, traveling slow before flying in a loop and then zooming toward the batter. While batting, a Bullet Bill is launched across the field, and if caught, the Bullet Bill pushes the catcher back a distance. Upon hitting the ground, the Bullet Bill turns back into a regular ball. In the Challenge Mode, purchasing a Bullet Bill at the item shop allows Bowser to perform Killer Ball. In the the final cutscene of ''Mario Super Sluggers'', a Bullet Bill is inserted into a cannon used for a Bob-omb Derby contest at Mario Stadium by Wario and Waluigi. When the Bullet Bill launches, Bowser emerges to hit it away from Mario and at Wario and Waluigi, blasting them away before setting off a chain reaction of fireworks.

===''Super Princess Peach''===
Bullet Bills are enemies in ''[[Super Princess Peach]]''. They appear from offscreen and can be defeated either from being [[stomp]]ed or with the [[Rage]] vibe. There are also mad variants known as the [[Mad Bullet Bill]]s, which fly faster than normal Bullet Bills. Pidgit Bills also make cameo appearances after Peach swipes with Perry at Bowser and the [[Vibe Scepter]] over the horizon and once Mario is saved.

===''Mario Strikers Charged''===
A Bullet Bill is a non-playable character in ''[[Mario Strikers Charged]]''. It is part of [[Shy Guy]]'s [[Skillshot]], known as [[Bullet Bill Blast]], where after charging the ball, Shy Guy summons a Bullet Bill and rides on it while holding the ball, going directly to the [[Kritter|Goalkeeper]] to knock him out in a explosion.

===''Mario & Sonic'' series===
[[File:M&S Big Bullet Bill Wii.png|thumb|left|Big Bullet Bill]]
Bullet Bills appear in various games of the [[Mario & Sonic (series)|''Mario & Sonic'' series]]. In the [[Nintendo DS]] version of ''[[Mario & Sonic at the Olympic Games (Nintendo DS)|Mario & Sonic at the Olympic Games]]'', Bullet Bills are enemies in [[Airship (minigame)|Airship]]. In the [[Wii]] version of ''[[Mario & Sonic at the Olympic Winter Games (Wii)|Mario & Sonic at the Olympic Winter Games]]'', Bullet Bills make their first appearance in an Olympic event, [[Dream Snowball Fight]], where they periodically appear in the area and knock down characters when they hit them, but can be turned around by hitting them with snowballs. In the Story Mode of the [[Nintendo 3DS]] version of ''[[Mario & Sonic at the London 2012 Olympic Games (Nintendo 3DS)|Mario & Sonic at the London 2012 Olympic Games]]'', Bowser Jr. uses a Bullet Bill to travel between areas, and there is an obtainable [[List of badges in Mario & Sonic at the London 2012 Olympic Games (Nintendo 3DS)|badge]] of a Bullet Bill from the badge machine. In ''[[Mario & Sonic at the Sochi 2014 Olympic Winter Games]]'', Bullet Bills are featured prominently in the [[Bullet Bill Sledge Race]] event, where each sled is pulled by a pair of harnessed Bullet Bills. In the Nintendo 3DS version of ''[[Mario & Sonic at the Rio 2016 Olympic Games (Nintendo 3DS)|Mario & Sonic at the Rio 2016 Olympic Games]]'', Bullet Bills appear in [[Boxing Plus]], as an item that can deplete the opponent's Guard Gauge, as well as [[Rhythmic Gymnastics Plus]], where they occasionally fire from offscreen to show upcoming buttons for the player to input.

Though Bullet Bills do not appear in the Nintendo DS version of ''[[Mario & Sonic at the Olympic Winter Games (Nintendo DS)|Mario & Sonic at the Olympic Winter Games]]'', a [[Big Bullet Bill]] appears as a rival in [[Mario & Sonic at the Olympic Winter Games (Nintendo DS)#Adventure Tours story|Adventure Tours]] mode, where it is faced in [[Cubyrinth]]. Big Bullet Bill is also the fourth rival in [[Skeleton (Mario & Sonic at the Olympic Winter Games for Wii)|Skeleton]] in Single Festival and the second rival in [[Bobsleigh (Mario & Sonic at the Olympic Winter Games for Wii)|Bobsleigh]] in Team Festival.
{{br|left}}

===''Mario and Donkey Kong: Minis on the Move''===
Bullet Bills are enemies in the minigame [[Elevation Station]] in ''[[Mario and Donkey Kong: Minis on the Move]]''. Bullet Bills in one of three sizes fly in from either side, trying to hit the [[Mini Mario (toy)|Mini Mario]] on the platform.

===''Captain Toad: Treasure Tracker''===
Bullet Bills are enemies in ''[[Captain Toad: Treasure Tracker]]'' and [[Captain Toad: Treasure Tracker (Nintendo Switch / Nintendo 3DS)|its ports]]. They act exactly as they did in ''Super Mario 3D World''. Bullet Bills can now be taken out with [[Turnip]] and redirected with spinwheels or moving blocks, often for destroying [[Rock Block]]s. [[Bull's-Eye Bill]]s return as well.

===''Puzzle & Dragons: Super Mario Bros. Edition''===
Bullet Bills are enemies and allies in ''[[Puzzle & Dragons: Super Mario Bros. Edition]]''. Their main attribute is Dark. As enemies, Bullet Bills sometimes deliver first strike blows, and tend to attack every turn. They can even increase the ATK of every enemy on the field, making their attacks deal more damage than normal to the player. As allies, Bullet Bills have a skill that halves the defense of all the enemies for three turns.

A Bullet Bill can be transformed into a [[Banzai Bill]] by giving it four [[Fire Flower]]s. Alternatively, giving a Bullet Bill three [[Goomba Coin]]s transforms it into a mash-up enemy, called Bullet Bill & [[Goomba]] (a solo Goomba on a Bullet Bill blaster). Six more Goomba Coins transforms Bullet Bill & Goomba into Bullet Bill & Goombas (two Goombas on a Bullet Bill blaster).

Bullet Bills have ATK as their highest stat, while their HP and RCV are very low.

===''Yoshi's Woolly World'' / ''Poochy & Yoshi's Woolly World''===
Bullet Bills are enemies in ''[[Yoshi's Woolly World]]'' and ''[[Poochy & Yoshi's Woolly World]]''. They take on a knitted appearance, consistent with the game's theme. The game introduces the [[Woollet Bill]] variant.

===''Yoshi's Crafted World''===
Bullet Bills are enemies in ''[[Yoshi's Crafted World]]''. They are depicted with their modern appearance in the level [[Spinwheel Shuffle]].

===''Dr. Mario World''===
Bullet Bills debut in the [[Dr. Mario (series)|''Dr. Mario'' series]] as assistants in ''[[Dr. Mario World]]''. In both stage mode and versus mode, their skill grants the doctor a chance in having a fully filled skill meter at the start of the stage, where the chance of activation is greater in versus mode compared to stage mode, at 20% to 60% chance in versus mode as opposed to stage mode's 4% to 20% chance.

Bullet Bills also appear during Dr. Roy's skill animation, which features them flying across the screen from left to right after his cannon is fired.

===''The Super Mario Bros. Movie''===
A Bullet Bill appears in the background of a {{file link|The Super Mario Bros. Movie Rainbow Road poster.jpg|poster}} for ''[[The Super Mario Bros. Movie]]'' showcasing [[Princess Peach]] and numerous [[Kong]]s driving on [[Rainbow Road]]. In the movie itself, [[Koopa Troopa]]s fire them out of the cannons of their karts at the same location. One Bullet Bill is fired from its Bill Blaster at Mario and Donkey Kong's [[Rocket Barrel]] upon their return from the [[Maw-Ray]], while several of them alongside some [[Koopa Paratroopa]]s are flying in [[Brooklyn]], being easily taken down by Invincible Mario and Luigi.

[[Princess Peach]]'s [[Training Course]] also features Bullet Bills alongside [[Banzai Bill]]s. However, these do not explode. Mario is knocked out by a Bullet Bill in one of his failed attempts to complete the course.

===Unused appearances===
====''Yoshi''====
Hidden within the data of the [[Game Boy]] version of ''[[Yoshi (game)|Yoshi]]'' is an unused Bullet Bill that would have functioned similarly to the [[Goomba]]s, [[Blooper]]s, [[Boo]]s, and [[Piranha Plant]]s in both that game and the [[Family Computer]] and [[Nintendo Entertainment System]] version.<ref>{{cite|url=tcrf.net/Yoshi_(Game_Boy)|title=''Yoshi'' (Game Boy)|language=en|publisher=The Cutting Room Floor|accessdate=October 20, 2021}}</ref> It is fully functional, though it turns into garbage graphics when it settles on a plate.

===Other appearances===
====''The Legend of Zelda'' series====
In ''{{iw|zeldawiki|The Legend of Zelda: Twilight Princess}}'', a Bullet Bill can be seen on the shirt of {{iw|zeldawiki|Fyer}}, a {{iw|zeldawiki|Hylian}} who operates the cannon at {{iw|zeldawiki|Lake Hylia}}.

====''Kirby'' series====
[[File:KabulaBulletBill.png|frame|left]]
In ''[[wikirby:Kirby Super Star Ultra|Kirby Super Star Ultra]]'', the boss [[wikirby:Kabula|Kabula]] has an attack that involves firing out missiles that resemble Bullet Bills. The only difference is that they have thrusters on their backs.
{{br|left}}

====''LEGO City Undercover''====
[[File:Mariocameo12LEGOCU.png|thumb|A Bullet Bill in ''{{wp|LEGO City Undercover|Lego City Undercover}}'']]
In ''{{iw|nwiki|Lego City Undercover|LEGO City Undercover}}'', a cannon in the King's Court district shoots LEGO Bullet Bills at Chase McCain when he approaches them. An optional puzzle requires Chase to use a Bullet Bill to break a cage resembling those seen in ''[[Super Mario Galaxy]]''. The Bullet Bill cameo was retained in the [[Nintendo Switch]] version of the game's remastered edition, but removed from all other versions.

===''Skylanders: SuperChargers''===
In ''[[Skylanders: SuperChargers]]'', Bullet Bills can be fired when Bowser is in the Clown Cruiser; however, due to an agreement between Nintendo and {{wp|Activision}}, they are featured exclusively in the Nintendo versions of the game.

===''Mario + Rabbids Kingdom Battle''===
Though Bullet Bills do not appear in ''[[Mario + Rabbids Kingdom Battle]]'', the Rocket [[List of weapons in Mario + Rabbids Kingdom Battle#Bullenator|Bullenator]] is modeled after one.

==General information==
===Physical appearance and traits===
Bullet Bills are black anthropomorphic {{wp|missile}}-like creatures. They have eyes with black pupils/irises and engines at their backsides, thus allowing them to travel in the air. In most games, they can be defeated by simply [[jump]]ing on them, though other games make them more resilient. Like other enemies, Bullet Bills have had varying appearances. In the earlier ''Super Mario'' games, Bullet Bills had a slightly brown hue, though this was due to color limitations. Bullet Bills were inspired by shark mouth {{wp|nose art}} on fighter planes<ref>{{cite|language=ja|url=www.ndw.jp/mario-220913-2|title=宮本茂さんに聞く“マリオたちの名前の由来”|publisher=''[[Nintendo DREAM]]'' WEB|date=September 13, 2022|accessdate=June 28, 2024}}</ref> and older artwork shows them with both arms and mouths, which are depicted variously in early sprites and models. To date, they appear with both arms and a visible mouth in the Game & Watch ''Super Mario Bros.'', the DIC Entertainment cartoons, ''Super Mario Bros. Print World'', the PC release of ''Mario's Time Machine'', ''Yoshi's Safari'', ''Super Mario RPG: Legend of the Seven Stars'', and ''Mario & Luigi: Superstar Saga''. In ''Super Mario Kart'', ''Super Mario 64'', and ''Yoshi's Story'', they lack arms but have an open mouth with sharp teeth and an angry expression, resembling [[Banzai Bill]]s. In ''Super Mario Land 2: 6 Golden Coins'', ''Super Mario World 2: Yoshi's Island'', and ''Yoshi's Island DS'', Bullet Bills display a grin instead, as well as a green color scheme in the second of these. In ''Super Mario Sunshine'', they have a slimmer shape in the vein of [[Torpedo Ted]]s, in addition to having a smile, fuller eyes, and rocket-like fins in the back. In the ''Nintendo Comics System'' and ''Mario Party Advance'', Bullet Bills are shown to be sentient and possess the ability to speak.

In most games, Bullet Bills simply fly around without targeting a victim, usually being launched from [[Bill Blaster]]s. However, the ''Super Mario Galaxy'' games give Bullet Bills the ability to home in on their opponents, while their eyes turn red. In the ''Super Smash Bros.'' games, Bullet Bills can also home in on their opponents, though only a few of them do this. In some cases, they can spin while flying. In ''Super Mario Odyssey'', Bullet Bills appear as [[Capture|capturable]] enemies; this game reveals that, Bullet Bills can fly at three different speeds, and can self-destruct after a certain period of time. In the ''Paper Mario'' games, Bullet Bills use a kamikaze attack, thus resulting in explosions. In ''Puzzles and Dragons: Super Mario Bros. Edition'', Bullet Bills are associated with the Dark attribute, boast higher ATK, and attack on every turn. The ''Mario & Sonic'' games depict Bullet Bill (and more specifically, [[Big Bullet Bill]]), as a Speed rival. This is supported by the ''Mario Kart'' series, which makes Bullet Bill a high-speed item with automatic turning capabilities. A billboard advertisement in ''Mario Kart Wii''{{'}}s [[Moonview Highway]] course addresses Bullet Bill as the "King of Speed".

==Profiles and statistics==
