'''Bullet Bills''' are anthropomorphic, bullet-like projectiles with arms and common enemies in the [[Super Mario (franchise)|''Super Mario'' franchise]]. They are horizontally shot out of [[Bill Blaster]]s, coupled with a firing sound effect to indicate their presence, and fly in a straight line, going through walls. Some Bullet Bills additionally approach from off-screen without the presence of a Bill Blaster, though a firing sound effect is still heard. Bullet Bills are immune to fireballs; in most games, Bullet Bills can be defeated by jumping on them. Ever since ''[[Super Mario 64]]'', some Bullet Bills have the ability to home in on Mario as a missile, similarly to [[Bull's-Eye Bill]]s. In some series, mostly the [[Mario Kart (series)|''Mario Kart'' series]], Bullet Bills have been portrayed as items, either as projectiles themselves or are used to take advantage of their speed by either riding on them or transforming into one. While they have been primarily portrayed as obstacles, some games depict them as individual characters.
==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 of a Bullet Bill from ''Super Mario Bros.'']]
Bullet Bills first appear in [[World 5-1 (Super Mario Bros.)|World 5-1]] of ''[[Super Mario Bros.]]'' They are usually shot from a [[Bill Blaster|Turtle Cannon]], though are sometimes shot from off-screen, and fly in a straight line, through walls. To defeat a Bullet Bill, the player has to either jump on them or use a [[Super Star|Starman]]. A kicked [[Koopa Troopa]] or [[Buzzy Beetle]] shell can defeat Bullet Bills that come from off-screen but harmlessly goes through ones shot from the Turtle Cannons. They are immune to fireballs from [[Fire Mario|Fiery Mario]]. Since Bullet Bills do not stop moving while they are still onscreen until they are defeated, if Mario reaches the flagpole while a Bullet Bill is still onscreen and then touches it, the Bullet Bill immediately disappears (this would later inspire how in later games, certain enemies near the end of a level immediately disappear and turn into coins if the level is successfully completed while they are still onscreen). Stomping on a Bullet Bill is always worth 200 points as the "point combo" rule for stomping from one Goomba, Koopa Troopa, or Buzzy Beetle onto another does not apply to Bullet Bills.

Bullet Bills and [[Piranha Plant]]s are the only two enemies from the original game whose death animations never depict them with their sprites flipped upside-down, the former remaining right side-up and the latter simply disappearing.

[[File:SMB2 Bullet Bill.png|thumb|left|Artwork of a Bullet Bill from ''Super Mario Bros.: The Lost Levels'']]
In ''[[Super Mario Bros.: The Lost Levels]]'', Bullet Bills behave exactly the same but the Turtle Cannons are more strategically-placed than in its predecessor. In ''[[Super Mario All-Stars]]'', a [[fake Bowser]] is a Bullet Bill in disguise 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''. Turtle Cannons appear in [[World 9-1 (Super Mario Bros.: The Lost Levels)|World 9-1]]; although they do not fire any Bullet Bills, they would theoretically be black with gray details, due to them sharing their palette with [[Blooper]]s.
{{br}}

====''Super Mario Bros. 3 / Super Mario Advance 4: Super Mario Bros. 3''====
Bullet Bills do not appear as much in ''[[Super Mario Bros. 3]]'' as they did in previous games, mainly appearing in later worlds and on the bosses' [[Airship]]s. They can be defeated with a [[Jump]], [[Koopa Shell]], [[Super Star|Starman]], [[Hammer]], [[Raccoon Mario|tail attack]], or a [[Bob-omb]] (on certain levels). [[Fire Flower]]s still do not affect them. A new type of Bullet Bill appears in this game, the [[Bull's-Eye Bill|Missile Bill]], which turns around and flies back towards Mario if it misses him the first time. They also appear in the remakes of this game: ''[[Super Mario All-Stars]]'' and ''[[Super Mario Advance 4: Super Mario Bros. 3]]''. In the latter, diagonally-fired Bullet Bills that would later be featured in ''Super Mario World'' appear in the [[World-e]] level [[Wild Ride in the Sky]].

====''Super Mario Land''====
{{main|Bullet Biff}}
Although the Bullet Bill does not appear in ''[[Super Mario Land]]'', a sub-species called Bullet Biff does appear.

====''Super Mario World'' / ''Super Mario World: Super Mario Advance 2''====
[[File:BulletBill-SMW.png|frame]]
''[[Super Mario World]]'' introduces Bullet Bills that are fired diagonally from four corners and vertically shot Bullet Bills. Their appearance is near-identical to that of the previous games. Bullet Bills are first encountered in [[Vanilla Dome 4]] where they are fired off-screen. In [[Cheese Bridge Area]], they are encountered in a zone led from a Warp Pipe. Bullet Bills emitted from Turtle Cannons are first encountered in [[Sunken Ghost Ship]], in addition to the only underwater level that features Bullet Bills. In the [[Special Zone]], [[Outrageous]] prominently features many Turtle Cannons that emit Bullet Bills. ''Super Mario World'' also features the debuts of derived Bullet Bill species such as [[Torpedo Ted]], which are Bullet Bills that are launched from [[torpedo tube]]s underwater. The larger [[Banzai Bill]]s also appear for the first time and appear before regular Bullet Bills. 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 also changed to this design, and they flap their wings rather than maintain a static image like ordinary Bullet Bills.

====''Super Mario Land 2: 6 Golden Coins''====
[[File:BulletBill-SML2.png|frame|left]]
Bullet Bills are commonly found in the [[Mario Zone]] in ''[[Super Mario Land 2: 6 Golden Coins]]''. Bullet Bills act much like the previous Bullet Bills in other games. They fly in a straight direction and are shot by Turtle Cannons. Mario can get rid of them by jumping on them or just dodging them, letting them fly off-screen. In this game, they have grinning faces and no arms.
{{br}}

====''Super Mario 64'' / ''Super Mario 64 DS''====
{{multiframe
|[[File:Bullet Bill SM64.png|160px]][[File:SM64DS Bullet Bill WF.png|160px]]|A Bullet Bill, as it appears in ''Super Mario 64'' (left) and ''Super Mario 64 DS'' (right).|size=320
|align=right
}}
In their first 3D appearance, Bullet Bills are found in only one location in ''[[Super Mario 64]]'': in the level [[Whomp's Fortress]]. Their appearance is similar to that of a Banzai Bill. After Mario defeats the [[Whomp King]], a Blaster appears at the top of the fortress. The Bullet Bills shot out home in on Mario and spin backwards upon contact with him; however, they explode after hitting a wall or reaching their maximum distance. Bullet Bills cannot be defeated in this game, and if Mario gets hit by one, he loses three wedges of [[Health Meter|health]].

In ''[[Super Mario 64 DS]]'', Bullet Bills can now appear at the new base of Whomp's Fortress, directly opposite of where Mario starts. They also appear in [[Dire, Dire Docks]], where they are seen at the submarine dock until the completion of [[Bowser in the Fire Sea]]. They can now be defeated by a well-timed kick or a [[Super Mushroom|Mushroom]], which sends them spinning backwards to eventually explode. They have also been redesigned to a standardized appearance, featuring arms and no visible mouth. Aside from the arms being colored gray instead of white, this design would become their typical design in following games.

This is the first platforming ''Super Mario'' game where Bullet Bills cannot be jumped on.
{{br}}

====''Super Mario Sunshine''====
[[File:Bullet Bill SMS.png|200px|thumb|left|A Bullet Bill as seen in ''[[Super Mario Sunshine]]'']]
For ''[[Super Mario Sunshine]]'', the appearance of Bullet Bills is greatly altered. One of the major changes includes the fact that the Bullet Bills in this game are smiling in a manner akin to [[Torpedo Ted]]s, as opposed to the ones from ''Super Mario 64'', which have a shark-like row of teeth like [[Banzai Bill]]s. In addition, the Bullet Bills in this game have an overall more robotic appearance, including a metallic exterior and google-eyes. They constantly make a quick radar beeping 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 instead release eight coins.

Black Bullet Bills are first shown at [[Pinna Park]] in [[Mecha-Bowser Appears!]], being fired from four cannons in [[Mecha-Bowser]]'s chest. They follow the tracks of the roller coaster Mario rides on for the fight, but loosely enough they may miss him by a wide margin on certain turns. They can either approach from the front or the back.

Later in the same course, black, purple, and golden Bullet Bills appear fired by [[Monty Mole]] in [[The Beach Cannon's Secret]]. 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>Hodgson, David S J, Bryan Stratton, and Stephen Stratton. ''Super Mario Sunshine'' Prima's Official Strategy Guide. Page 19.</ref> which have blinking red nosecones, follow Mario on a horizontal plane if they approach him, similar to the Bullet Bills in ''[[Super Mario 64]]'', though with a tight-but-lengthy u-turn if they miss comparable to the [[Bull's-Eye Bill|Missile Bill]]s in ''[[Super Mario Bros. 3]]''. They are used for breaking open the baskets that hold [[Blue Coin]]s found across the beach. In the game's demo reel, viewable by waiting on the "press start" screen, both black and purple Bullet Bills are shown with blinking red noses as well as solid red eyes with white pupils, suggesting the design was changed slightly very late in development.

In the first episode of [[Noki Bay]], [[Uncork the Waterfall]], a single inactive black Bullet Bill makes a small cameo laying dormant in the platform connecting the cannon to the giant cork.

At the end off the game during the fight against [[Bowser]] and [[Bowser Jr.]], the latter shoots Bullet Bills that are also known as '''special Purple Bullet Bills'''<ref>Hodgson, David S J, Bryan Stratton, and Stephen Stratton. ''Super Mario Sunshine'' Prima's Official Strategy Guide. Page 19.</ref> or '''Guided Bullet Bills''',<ref>Bogenn, Tim, and Doug Walsh. ''Super Mario Sunshine'' BradyGames Official Strategy Guide. Page 133.</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, though due to the amount that are launched at once as the fight goes on, each has a fairly short and narrow line-of-sight, and they can also change their altitude to get on his level. These can be defeated by jumping on them, with the blue ones giving a [[1-Up Mushroom]] or [[Water Bottle]] if beaten this way. They are also immediately destroyed by Bowser's [[Fire Breath]].

====''New Super Mario Bros.''====
[[File:6-1 NSMB.png|200px|thumb|[[Luigi]] defeating Bullet Bills in World 6-1 of ''New Super Mario Bros.'']]
In ''[[New Super Mario Bros.]]'', Bullet Bills appear in various levels, and are shot out of not only [[Bill Blaster]]s, but also [[Bill Blaster Turret]]s. They appear in {{world-link|2|castlen|World 2-Castle (New Super Mario Bros.)}}, [[World 5-4 (New Super Mario Bros.)|World 5-4]], [[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]] boss fight), [[World 7-5 (New Super Mario Bros.)|World 7-5]], and [[World 8-1 (New Super Mario Bros.)|World 8-1]]. If the player jumps on them, they are defeated. They also can be defeated by hitting them with a [[Green Shell|Shell]], or using a [[Super Star|Starman]] or [[Mega Mushroom]], and are again immune to fireballs. Banzai Bills return, and their [[Banzai Bill Cannon|cannon]] is introduced. In World 5-4, they fly out from somewhere off-screen rather than being fired from Bill Blasters.
{{br}}

====''Super Mario Galaxy''====
[[File:SMG Bullet Bill.png|200px|thumb|left|A Bullet Bill as it appeared in ''Super Mario Galaxy'']]
[[File:SMG Megaleg Head Bullet Bills.png|thumb|A Bullet Bill chases Mario in ''Super Mario Galaxy'']]
Bullet Bills reappear in ''[[Super Mario Galaxy]]''. After they have been fired, if they spot the player, their eyes turn red and they home in on Mario until they hit him, an obstacle, or an enemy. This method can be used to break open cages and destroy fences. In [[Bowser Jr.'s Robot Reactor]] the robotic boss [[Megaleg]] is defeated in this way. If they hit Mario, he is knocked down for a few seconds and loses a wedge of health. They are one of the most common enemies in the game, appearing in several galaxies. [[Torpedo Ted]]s also appear and can be used the same way as Bullet Bills, although Torpedo Teds make a specific radar sound in order to tell the player how close they are. [[Banzai Bill]]s also appear on [[Bowser's Galaxy Reactor]], shot from [[Banzai Bill Cannon]]s, but do not home in on the character.
{{br}}

====''New Super Mario Bros. Wii''====
[[File:NSMBW Bullet Bills Screenshot.png|thumb|200px|Bullet Bills in World 7-4 of ''New Super Mario Bros. Wii'']]
Bullet Bills also appear in ''[[New Super Mario Bros. Wii]]'', with their behavior from ''New Super Mario Bros.'' Banzai Bills, Bill Blaster Turrets, and Banzai Bill Cannons also reappear. This game also introduces [[King Bill]]s, which are indestructible and much bigger than even a [[Banzai Bill]], as well as a [[Bull's-Eye Banzai|homing Banzai Bill]]. Even though Bullet Bills are still fireproof, 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. Missile Bills also appear in this game, but instead of just turning around when they miss, they home in on Mario, similar to the Bullet Bills from ''Super Mario Galaxy''. They first appear in [[World 3 (New Super Mario Bros. Wii)|World 3]] and have an important role in [[World 6 (New Super Mario Bros. Wii)|World 6]] as [[Enemy Course]]s. They also appear in several levels of [[World 7 (New Super Mario Bros. Wii)|World 7]]. In [[World 5-5 (New Super Mario Bros. Wii)|World 5-5]], Bullet Bills fly out from somewhere off-screen instead of being fired from Bill Blasters.
{{br}}

====''Super Mario Galaxy 2''====
[[File:MegaHammerBattle.png|200px|thumb|left|Bullet Bills chasing Mario and [[Yoshi]] while battling Megahammer in ''[[Super Mario Galaxy 2]]'']]
Bullet Bills also appear in ''[[Super Mario Galaxy 2]]'', the sequel to ''[[Super Mario Galaxy]]''. Many of them retain their homing capabilities in this game, though some Bullet Bills in [[Bowser Jr.'s Fearsome Fleet]] and [[Bowser's Galaxy Generator]] fly straight and do not follow Mario whatsoever. In certain galaxies, [[Yoshi]] can use his tongue to capture an incoming Bullet Bill in his mouth for a short time, and then spit it back out at other incoming enemies or bosses. This plays an important role in the defeat of [[Megahammer]] in Bowser Jr.'s Fearsome Fleet, as the giant robot continuously fires multiple Bullet Bills at Mario every few seconds. The player must hit Megahammer with Bullet Bills a total of eight times in order to defeat it. [[Banzai Bill]]s also appear, but [[Torpedo Ted]]s do not.
{{br}}

====''Super Mario 3D Land''====
[[File:SM3DL Bullet Bill.PNG|thumb|Bullet Bills in [[World 2-Airship (Super Mario 3D Land)|World 2-Airship]] in ''Super Mario 3D Land'']]
Bullet Bills reappear as enemies in ''[[Super Mario 3D Land]]''. Similar to 2D ''Super Mario'' games, [[stomp]]ing on one or hitting one with a [[boomerang]] defeats it instantly, making this the first 3D ''Super Mario'' game in which this is possible. After [[Tanooki Mario]] tail whips a Bullet Bill, it changes its angle after a spin and keeps flying. Some Bullet Bills have [[Raccoon Mario|striped tail]]s and are called [[Tail Bullet Bill]]s. Like in the other 2D games, Bullet Bills are impervious to fireballs and only go in one direction.
{{br}}

====''New Super Mario Bros. 2''====
[[File:Gold Bullet Bill Artwork - New Super Mario Bros. 2.png|thumb|left|A Gold Bullet Bill from ''New Super Mario Bros. 2'']]
Bullet Bills appear in ''[[New Super Mario Bros. 2]]'', with the same appearance they have in past games and fly in a straight line. When Mario or Luigi touches a [[Gold Ring]], Bullet Bills become golden (in a similar way to the Bullet Bills in ''[[Yoshi's Story]]'', and bearing an appearance slightly similar to the [[Bombshell Bill]] sub-species from the ''[[Paper Mario (series)|Paper Mario]]'' series) and leave a trail of coins behind them. Jumping on the Bullet Bills themselves discontinue the production of any more coins. In addition to horizontally flying Bullet Bills, diagonally flying ones from ''Super Mario World'' can be found in the [[Coin Rush]]-exclusive course packs [[Coin Challenge Pack B]] and [[Platform Panic Pack]].
{{br}}

====''New Super Mario Bros. U''====
Bullet Bills appear in ''[[New Super Mario Bros. U]]''. They act just like they did in past installments. However, the Bullet Bills produce a red smoky flare, similar to their behavior in ''Super Mario 3D Land''. In ''New Super Mario Bros. Wii'', the Bullet Bills only ejected puffy cloud smoke. Bullet Bills also appear in the battle against [[Roy Koopa]]. He holds a Bill Blaster and shoots Bullet Bills at the players as his battle strategy. [[Torpedo Ted]]s from ''Super Mario World'' also reappear. They now have a sub-species under the name [[Targeting Ted]]s.

====''Super Mario 3D World'' / ''Super Mario 3D World + Bowser's Fury''====
[[File:BulletBillSM3DW.jpg|thumb|Bullet Bills from ''Super Mario 3D World'']]
Bullet Bills return in ''[[Super Mario 3D World]]'' and its [[Nintendo Switch]] port ''[[Super Mario 3D World + Bowser's Fury]]''. Similar to the Tail Bullet Bills in ''Super Mario 3D Land'', a [[Cat Bullet Bill]] based on the [[Cat Mario]] transformation also appear. They feature black and white cat ears and a tail, as well as being colored black on top and white on the bottom. These Bullet Bills chase after Mario, similar to a Missile Bill.
{{br}}

====''Super Mario Maker'' / ''Super Mario Maker for Nintendo 3DS''====
[[File:Img mashiko 02.gif|thumb|left|[[Mary O.]] hammering a loose nail on a [[Bill Blaster]]]]
Bullet Bills reappear in ''[[Super Mario Maker]]'' and ''[[Super Mario Maker for Nintendo 3DS]]'' as enemies. However, they are not standalone enemies, and can only come out of Bill Blasters. [[Bull's-Eye Bill]]s also reappear, and they are fired from [[Bull's-Eye Blaster]]s.
{{br}}

====''Super Mario Run''====
Bullet Bills reappear in ''[[Super Mario Run]]'', in the levels [[Sky-High Lifts and Leaps!]] and [[Bullet Bill Barrage]]. They are fired from offscreen, and they have the same behavior as they do in other ''Super Mario'' titles. Bull's-Eye Bills also appear.

====''Super Mario Odyssey''====
[[File:SMO Art - E3 Char7.png|thumb|A Bullet Bill captured by Mario as seen in ''Super Mario Odyssey'']]
Bullet Bills and Bill Blasters reappear in ''[[Super Mario Odyssey]]''. They appear in the [[Metro Kingdom]] and the [[Sand Kingdom]], where they can be seen wearing visors. They also appear in the Underground Caverns in the [[Moon Kingdom]], where they wear white top hats. Mario can throw [[Cappy]] at a Bullet Bill to knock its hat off, allowing it to be [[capture]]d. When they are fired from a Bill Blaster, they chase after Mario, exploding after a little while. When a Bullet Bill is captured with Cappy, Mario is able to fly across pits, though the Bullet Bill explodes if it hits a wall or if Mario controls it for too long. Bullet Bills that use their sprites from ''Super Mario Bros.'' can be found in two-dimensional parts through murals, where they are fired from Bill Blasters. These Bullet Bills travel in straight lines instead of following Mario. If a two-dimensional part ends before the wall it is on does so, a Bullet Bill which has not been defeated leaves the mural, transforms into its three-dimensional counterpart and starts chasing Mario.
{{br}}

====''Super Mario Maker 2''====
In ''[[Super Mario Maker 2]]'', Bullet Bills appear in a similar capacity as the game's predecessor. In the ''Super Mario 3D World'' style, Bullet Bills can defeat enemies that they run into, and are defeated when they hit a wall. In version 3.0.0, a new wearable item exclusively for the ''Super Mario 3D World'' style based on the Bullet Bills was introduced called the [[Bullet Bill Mask]].

====''Super Mario Bros. Wonder''====
[[File:SMBW screenshot Blasted Bill.png|thumb|A Missile Meg under the effect of a [[Wonder Flower]]]]
Bullet Bills return in ''[[Super Mario Bros. Wonder]]''; in addition, the game introduces some new variants of Bullet Bill including [[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. These new variants appear prominently in [[Castle Bowser]] levels.

===''Alleyway''===
[[File:Stage15 Alleyway.png|thumb|left|The Bullet Bill block formation in stage 15 of ''[[Alleyway]]'']]
In ''[[Alleyway]]'', a multitude of breakable blocks are manipulated to shape a Bullet Bill sprite. The construction is found in the fifteenth stage of the game. The players are given 80 in-game time units to destroy the blocks that form the Bullet Bill, using the ball that bounces off their capsule.

[[File:CartoonBill.jpg|thumb|Three Bullet Bills from ''The Super Mario Bros. Super Show!'' episode "[[Robo Koopa (episode)|Robo Koopa]]"]]
Bullet Bills make only one appearance in ''[[The Super Mario Bros. Super Show!]]'', in the series finale of the show, "[[Robo Koopa (episode)|Robo Koopa]]", although Bullet Bill-like projectiles with faces are fired by a Snifit in the earlier episode "[[On Her Majesty's Sewer Service]]". They have gray bodies with peach-colored arms and toothy grins.

====''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]]"]]
In ''[[The Adventures of Super Mario Bros. 3]]'', Bullet Bills make two small appearances in the episodes "[[Reptiles in the Rose Garden]]" and "[[Mush-Rumors]]," where they are fired from the [[Bowser's Airship|Doom Ship]]. In the latter they are fired alongside other munitions during the Koopa family's attack on a group of "aliens," who are actually a human family made up of [[Norman]], [[Bud and Missy's mother|his wife]], and their children [[Missy]] and [[Bud]].

===''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===
In the [[Mario Kart (series)|''Mario Kart'' series]], Bullet Bills<ref>「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''. {{media link|SMK NOG Killer.png|Page 126}}.</ref> appear as both obstacles and items.

====''Super Mario Kart''====
{{multiframe|[[File:SMK Bullet Bill.png]]|size=130|A Bullet Bill in ''Super Mario Kart''}}
Bullet Bills appear in ''[[Super Mario Kart]]''{{'}}s Match Race, where they act 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. They only appear from the front, similar to in ''[[Yoshi's Safari]]''.

====''Mario Kart DS''====
[[File:MKDS Bullet Bill Artwork.jpg|thumb|left|A Bullet Bill in ''Mario Kart DS'', its first appearance as an item]]
In ''[[Mario Kart DS]]'', Bullet Bills appear as obstacles on the [[DS Airship Fortress|Airship Fortress]] race course. When a racer hits one, they are knocked over, dropping any item they are carrying.

Bullet Bills also appear as an item that can be received by players in 6th place or lower. Upon activating, the player's entire kart transforms into a Bullet Bill, which rockets down the track on auto-pilot at very high speeds (although the player still has a very small degree of steering control). The Bullet Bill is invincible, which allows the player to knock over any course obstacles and other drivers in the way, similar to the [[Chain Chomp]] from ''[[Mario Kart: Double Dash!!]]''; players damaged by a collision with the Bullet Bill also lose any item in their possession. Players under the effects of a [[Super Star|Star]] or a [[Boo]] are not be damaged if a Bullet Bill runs into them, although the former does get nudged out of the way. The duration of the Bullet Bill depends on the player's current position, with it lasting longer if the player is near or at last place, and it lasting only a few seconds if the player is leading the race. Upon expiring, the player reverts to their normal kart. The main downside of the Bullet Bill is that it can sometimes expire at the wrong moment, such as before a sharp bend, or while the auto-pilot is steering the player on the edge of the track, which can result in the player falling off the course right after reverting to their normal kart. In addition, the player cannot receive any items while they are transformed into a Bullet Bill.

====''Mario Kart Wii''====
[[File:MKW Bullet Bill Screenshot.png|thumb|Wario using a Bullet Bill]]
Bullet Bills reappear as an item in ''[[Mario Kart Wii]]''. They can only be received by players in 8th place or lower in this game. The best chance of getting this item is in 12th place, with a 25 percent (10 out of 40) chance of getting it in said position. They behave the same way as they do in ''Mario Kart DS''. Players under the effects of a [[Mega Mushroom]] can be knocked back by this item. It is one of six items wherein only one can be in play at a time (the other five being the [[Thunder Cloud]], [[Spiny Shell (blue)|Spiny Shell]], [[Blooper]], [[POW Block]], and [[Lightning]]). Once a Bullet Bill is used, another Bullet Bill cannot be obtained until the current one is exhausted.

The [[Bullet Bike]], which is a bike designed for small-sized characters, is based off the design of the Bullet Bill.

====''Mario Kart 7''====
Bullet Bills reappear as an item in ''[[Mario Kart 7]]'', behaving similarly to the way they do in ''Mario Kart Wii''. In addition, the Bullet Bill now slows down when it is about to expire, thus reducing the likelihood of players falling off the course if it expires at an awkward location on the track. The warning sound from ''Mario Kart Wii'' can be heard when a Bullet Bill appears on the Touch Screen. Like ''Mario Kart DS'', Bullet Bills in this game can only be received by players in 6th place or lower.

====''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 reappear as an item in ''[[Mario Kart 8]]'' and [[Mario Kart 8 Deluxe|its port]]. In these games, Bullet Bill's eyes glow in the dark, as seen in courses without light, such as [[Twisted Mansion]]. Additionally, in ''Mario Kart 8'' (as well as early versions of ''Mario Kart 8 Deluxe''), it is impossible to use the rear-view mirror while using a Bullet Bill; however, as of version 2.3.0 of ''Mario Kart 8 Deluxe'', this is no longer the case.

Bullet Bills can be received by players that are far enough away from the leader due to the new item system introduced in these games. Unlike the previous ''Mario Kart'' games, up to three players can use a Bullet Bill at the same time.

Bullet Bills also have a sponsor in ''Mario Kart 8'' and ''Mario Kart 8 Deluxe'' named after them, [[Bullet Bill Speed Trial]].

====''Mario Kart Tour''====
Bullet Bills reappear as an item 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 when it hits 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>[http://www.nintendoplayer.com/feature/super-mario-bros-movie/ Fungus Among Us: Super Mario Bros. Movie Memorabilia Saved from the Set]</ref>

===''Yoshi's Safari''===
Bullet Bills are enemies in a few levels of ''[[Yoshi's Safari]]''. They come at [[Mario]] head on and are shot down with one hit from the [[Super Scope]]. The Turtle Cannons are not visible, the bill's come from somewhere off screen. In this game the Bills come at the player head on, a perspective rarely seen of them.

===''Mario's Time Machine''===
[[File:Bullet Bill MTMDX.png|frame]]
In the PC release of ''[[Mario's Time Machine]]'', Bullet Bills appear if [[Mario]] makes a mistake when setting the [[Timulator]]'s date. He is then sent to the far-flung past, in which he must catch eggs that are being dropped by a [[pterodactyl]] while Bullet Bills fly towards Mario from off-screen. Mario loses one of his caught eggs if he is hit by a Bullet Bill, and he can dodge them by walking towards them, causing him to automatically jump over them.

===''Yoshi's Island'' series===
[[File:BulletBill-SMW2.png|frame|left]]
Bullet Bills appear as enemies in ''[[Super Mario World 2: Yoshi's Island]]'', where they are colored green instead of black, and feature facial expressions as well. This game also introduces [[Bouncing Bullet Bill]]s, which bounce and ricochet off walls after being fired. The [[Yoshi's Island: Super Mario Advance 3|Game Boy Advance version]] also adds [[Bull's-Eye Bill|Missile Bill]]s that home in on Yoshi while biting upon being shot out of their cannons. Any of the Bullet Bills in this game can be defeated by the way most enemies can be defeated. 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>TCRF. [[tcrf:Development:Super Mario World 2: Yoshi's Island/Sprites#killer.CGX|Development:Super Mario World 2: Yoshi's Island/Sprites#killer.CGX]]. ''The Cutting Room Floor''. Retrieved November 12, 2021.</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]]
In ''[[Yoshi's Story]]'', Bullet Bills follow the same pattern as in other games. However, this 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.

{{multiframe|[[File:BulletBill-GWGallery3DKJr.png]] [[File:BulletBill-GWGallery4DKJr.png]]|size=200|align=left|A Bullet Bill in the Donkey Kong Jr. remakes in ''Game & Watch Gallery 3'' (left image) and ''Game & Watch Gallery 4'' (right image)}}
In ''[[Game & Watch Gallery 3]]'' and ''[[Game & Watch Gallery 4]]'', Bullet Bills make an appearance in the Modern mode of ''[[Donkey Kong Jr. (Game & Watch)|Donkey Kong Jr.]]'' Their role is the same in both games, as they attempt to stop [[Donkey Kong Jr.]] as he attempts to free his father. Additionally, in ''Game & Watch Gallery 4'', Bullet Bills appear in the Modern version of ''[[Fire Attack]]'', where they attempt to destroy a statue belonging to [[Wario]].

===''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.]]'', where one of [[smashwiki:Master Hand|Master Hand]]'s attacks is to fire 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 the early ''Yoshi'' platformers.

''[[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 primary [[Spirit (Super Smash Bros. Ultimate)|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 is encountered on the [[smashwiki:Light Realm|Light Realm]] map; the puppet fighters are four small [[Captain Falcon]]s 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''====
In ''[[Mario Party 2]]'', Bullet Bills appear in the minigame [[Bombs Away (minigame)|Bombs Away]] where a Bowser ship fires them. Here, unlike cannonballs, they always land on the island, forcing the player to time their jumps right to avoid being stunned by the explosion.

====''Mario Party 3''====
In ''[[Mario Party 3]]'', Bullet Bills are featured in the minigame [[Crazy Cogs]]. The solo player must rotate the cog the three players are standing on so they hit the three players as they continuously bombard the cog. They also make a cameo in [[Pump, Pump and Away]]. The minigame [[Ridiculous Relay]] also features Bullet Bills as obstacles alongside [[Paragaloomba]]s, and also features a Bullet Bill-like boat. [[Aces High]] has the players riding gliders with Bullet Bills attached to the underside, with them also being usable to attack the other players.

====''Mario Party 5''====
Bullet Bills appear in ''[[Mario Party 5]]'' in the form of the [[Bullet Bill Orb|Bullet Bill Capsule]]. It can either be thrown on a space or used for five coins. When used, the player continues their turn as normal, but riding a Bullet Bill. Any opponents they pass during this time have 30 coins stolen from them.

Bullet Bills also appears in the minigame [[Bill Blasters (minigame)|Bill Blasters]]. The minigame involves players shooting the bullets at each other in order to eliminate the other players.

====''Mario Party 6''====
In ''[[Mario Party 6]]'', the Bullet Bill Orb returns with the same effect. However, the user only steals 20 coins from opponents. They are also featured in the minigame [[Jump the Gun]], which involves one player shooting Bullet Bills at targets to form a platform for their partner. Bullet Bills are also used in [[Shoot Yer Mouth Off]]; saying 4, 8, or 9 causes the solo player to shoot a Bullet Bill to try and eliminate the other three. Additionally, the "Bullet Bill" voice command for the minigame [[Verbal Assault]] can be bought at the Star Bank; using it fires a Bullet Bill that homes in on one of the three players. The [[Magma Flow]] path in [[Star Sprint]] also has Bullet Bills being shot at the player.

====''Mario Party Advance''====
[[File:MPA Bullet.png|frame|left]]
[[File:MPAmushstadium.png|frame]]
{{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 appears in ''[[Mario Party Advance]]'' as a track and field athlete at the [[Mushroom Stadium]]. The Bullet Bill's quest involves challenging him to a race. He is also a huge fan of the [[Kamek Krew]], owning all of their albums and even letting them perform at his stadium.

When he is first met in Mushroom Stadium, the player challenges him to a race for a [[Gaddget]], and once beaten he will hand over the [[Mini Soccer]] Gaddget. Sometime after, the Kamek Krew asks the player to find a stadium where they can perform; the player can ask Bullet Bill if he'll rent out his stadium. At first he is hesitant, but once the player mentions that the Kamek Krew made the request, he eagerly obliges and mentions that they can perform in his stadium free of charge. He then goes off to make the preparations, but not before telling the player to tell the Kamek Krew he said "howdy". By the end of the game, it is mentioned that he finished second in the world sprint trials.

Bullet Bills also appear in the minigame [[Bill Bounce]]. The minigame involves the player attempting to jump on Bullet Bills to earn enough points in the allotted time. Hitting one temporarily stuns the player, and jumping on several consecutively earns the player more points.

====''Mario Party 7''====
Bullet Bills appear in ''[[Mario Party 7]]'' in the minigame [[Wheel of Woe]]. By saying their name, two Bullet Bills are shot out of blasters on each side of the room in an attempt to eliminate the other three players. Bullet Bills also appear in [[StratosFEAR!]] serving as obstacles to three players while the remaining one moves a mushroom up and down by commanding it. Bullet Bills appear in the minigame [[Helipopper]] to hamper with a player's progress.

====''Mario Party 8''====
[[File:MP8 Red Bullet Bill.png|thumb|left|Bullet Bills in the ''Mario Party 8'' minigame, Superstar Showdown]]
In ''[[Mario Party 8]]'', there is an item called [[Bullet Candy]] that appears only in [[Bowser's Warped Orbit]]. It transforms the player's bottom half into the end of a Bullet Bill and allows them to hit three [[Dice Block]]s (similar to [[Thrice Candy]]). For every opponent the player runs in to, one Star is stolen from them.

Bullet Bills appear as obstacles in the [[Sick and Twisted]] and [[Thrash 'n' Crash]] minigames as obstacles that must be avoided; any player who touches a Bullet Bill is eliminated even if, in the case of Sick and Twisted, they jump on the Bullet Bill. During the second stage of the final minigame [[Superstar Showdown]], two cannons attach themselves to Bowser's Clown Car; these cannons fire black Bullet Bills during the second stage and red Bullet Bills during the third stage, which both slightly steer themselves at the player character. Also, a helicopter which resembles a Bullet Bill appears in the mini-game [[Gun the Runner]]; it holds the three players trying to eliminate the solo player. Finally, the duel minigame [[Cardiators]] features a card with a trio of Bullet Bills on it; selecting this card fires three Bullet Bills at the opposing player and inflicts nine damage upon them.

====''Mario Party 9''====
[[File:MP9 4-Player Billistics.png|thumb|Bullet Bills are the focus of the ''Mario Party 9'' minigame, Billistics]]
In ''[[Mario Party 9]]'', Bullet Bills, along with [[Bull's-Eye Bill|Missile Bill]]s, appear in the minigame [[Billistics]], the name being a pun on their name and "ballistics".

====''Super Mario Party''====
Bullet Bills appear in ''[[Super Mario Party]]'' as non-playable characters. They are featured in the minigames [[Follow the Money]] and [[Drop Quiz]].

===''Paper Mario'' series===
====''Paper Mario''====
Normal Bullet Bills reappear in ''[[Paper Mario]]'' 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 [[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.

====''Paper Mario: The Thousand-Year Door''====
[[file:PMTTYD Bullet Bill Sprite.png|thumb|40px]]
In ''[[Paper Mario: The Thousand-Year Door]]'', Bullet Bills appear as enemies in the [[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''====
Bullet Bills only appear once in [[The Bitlands]] at [[Bowser]]'s castle in ''[[Super Paper Mario]]''. 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''====
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>[https://tcrf.net/Paper_Mario:_Sticker_Star#Enemies Paper Mario: Sticker Star § Enemies]. ''The Cutting Room Floor''. Retrieved November 12, 2018.</ref>

====''Paper Mario: Color Splash''====

====''Paper Mario: The Origami King''====
Bullet Bills do not appear as enemies in ''[[Paper Mario: The Origami King]]'', though they make brief appearances. They can be seen in the background of the [[Buzzy Beetle]] statue room in [[Bowser's Castle]], and are fired from [[Bowser]]'s airship at the [[Paper Plane Squadron]] before [[Mario]] fights them. One Bullet Bill appears as a Collectible Treasure, which can be found inside one of the [[? Block]]s at the south-western corner of the room with [[Boomerang Bro]]s. in [[Origami Castle]].

===''Mario Golf'' series===
Bullet Bills appear in ''[[Mario Golf: Toadstool Tour]]'' being shot out of Bill Blasters resembling the Monty Mole's cannons from ''Super Mario Sunshine'' atop towers. They land into the water but are purely for aesthetic purposes. In ''[[Mario Golf: World Tour]]'', Bullet Bills can be used as item shots; they increase the player's maximum driving distance and also cause the ball to travel in a straight line, ignoring wind and player stats. In ''[[Mario Golf: Super Rush]]'', Bowser Jr. rides a Bullet Bill for his [[Special Dash]] in a similar fashion to ''[[Mario & Sonic at the London 2012 Olympic Games]]''.

===''Mario & Luigi'' series===
====''Mario & Luigi: Superstar Saga'' / ''Mario & Luigi: Superstar Saga + Bowser's Minions''====
In ''[[Mario & Luigi: Superstar Saga]]'' and ''[[Mario & Luigi: Superstar Saga + Bowser's Minions]]'', Bill Blasters in [[Stardust Fields]] fire Bullet Bills 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 [[Game Boy Advance]] game, 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 UFO]]s attack.

====''Mario & Luigi: Bowser's Inside Story'' / ''Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey''====
Bullet Bills make yet another appearance in the game ''[[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. When shot, the Bullet Bills may turn invisible and attack one of the Mario Brothers. The player has to know when to dodge it when this happens.

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]].

One of the Special Games, [[Mecha-Bowser Mayhem]], features Bullet Bills are 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:Killer Ball.png|thumb|Bowser using a Bullet Bill in his Killer Ball move in ''Mario Superstar Baseball'']]
Bullet Bills appear in both games of the [[Mario Baseball (series)|''Mario Baseball'' series]]: ''[[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''. While pitching, a Bullet Bill is launched at the batter. It goes slow at first, but when it gets close to the batter, it flies in a loop, then zoom pass the batter, making it harder for them to hit.

Exclusively in ''Mario Superstar Baseball'', [[Bowser Jr.]] can use a Bullet Bill in his Star Skill, [[Killer Jr. Ball]]. Bowser Jr.'s Bullet Bill wears a bandana similar to his, unlike Bowser's. While batting, when Bowser or Bowser Jr. hit the ball, they launch a Bullet Bill across the field which, if caught, pushes the catcher far back. 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 ''Mario Super Sluggers'', Bowser instead uses [[Breath Swing]] while batting, and Bowser Jr. instead uses [[graffiti]] in his two Star Skills, [[Graffiti Ball]] and [[Graffiti Swing]].

In ''Mario Super Sluggers''{{'}}s final cinematic, Wario and Waluigi sabotage a cannon that is being used for a Bob-omb Derby contest at Mario Stadium by inserting a Bullet Bill into the cannon, which launches prematurely and aims directly toward Mario. Bowser emerges out of nowhere and uses his own bat to hit the Bullet Bill, which takes Wario and Waluigi with it, sending the duo blasting off before setting off a chain reaction of fireworks.

===''Super Princess Peach''===
Bullet Bills appear in ''[[Super Princess Peach]]'' as enemies that come from off-screen. They can be defeated by stomping on them 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 makes an appearance in ''[[Mario Strikers Charged]]''. It appears as the [[Skillshot]] of [[Shy Guy]] known as [[Bullet Bill Blast]]. Upon fully charging the [[Soccer Ball|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 and possibly score.

===''Mario & Sonic'' series===
[[File:M&S Big Bullet Bill Wii.png|thumb|left|Big Bullet Bill]]
Bullet Bills have appeared 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 a rival in [[Skeleton (Mario & Sonic at the Olympic Winter Games for Wii)|Skeleton]] in Single Festival and [[Bobsleigh (Mario & Sonic at the Olympic Winter Games for Wii)|Bobsleigh]] in Team Festival.

===''Puzzle & Dragons: Super Mario Bros. Edition''===
Bullet Bills make an appearance as enemies in ''[[Puzzle & Dragons: Super Mario Bros. Edition]]''. Their main attribute is Dark.

As enemies, Bullet Bills sometime deliver first strike blows, and tend to attack every single 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''===
[[File:YWW Bullet Bill.jpg|thumb|A Bullet Bill as seen in ''Yoshi's Woolly World'']]
Bullet Bills, along with Bill Blasters, make an appearance in ''[[Yoshi's Woolly World]]'' and ''[[Poochy & Yoshi's Woolly World]]'', adopting a knitted appearance rather than the usual metallic look.

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 {{media 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.

===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 [[Nintendo Entertainment System|NES]] version.<ref>[https://tcrf.net/Yoshi_(Game_Boy) Yoshi (Game Boy) - The Cutting Room Floor)]. ''TCRF''. Retrieved 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 ''[[zeldawiki:The Legend of Zelda: Twilight Princess|The Legend of Zelda: Twilight Princess]]'', a Bullet Bill can be seen on the shirt of [[zeldawiki:Fyer|Fyer]], a [[zeldawiki:Hylian|Hylian]] that operates the cannon at [[zeldawiki:Lake Hylia|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.

====''LEGO City Undercover''====
[[File:Mariocameo12LEGOCU.png|thumb|A Bullet Bill in ''{{wp|LEGO City Undercover|Lego City Undercover}}'']]
In ''{{wp|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>[https://www.ndw.jp/mario-220913-2/ "Shigeru Miyamoto on the origin of the names of Mario and his friends"]. ''[[Nintendo DREAM]]''. February 2010 volume. Retrieved April 22, 2023.</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==
{{main|List of Bullet Bill profiles and statistics}}
Most Bullet Bill bios highlight their trademark habit of soaring through the air and the Bill Blaster which they are shot out of.
