Bullet Bill

Bullet Bills are bullet-like projectiles in the Mario franchise. They are shot out of Bill Blasters and are usually under Bowser's control, acting as enemies of Mario since their debut in Super Mario Bros. Ever since Super Mario 64, some Bullet Bills have the ability to home in on Mario as a missile, similar to Bull's-Eye Bills. They also have increasingly been items, mostly in the Mario Kart series. Other games depict them as sentient beings with emotions, and some talk in the cartoons.

Super Mario Bros.
Bullet Bills first appear in World 5-1 of Super Mario Bros. They are usually shot from a large Turtle Cannon, though are sometimes shot from off-screen, and fly in a straight line. To defeat a Bullet Bill, the player has to either jump on them, kick a Koopa Shell at them or use a Starman. They are immune to fireballs from Fiery Mario.

Super Mario Bros.: The Lost Levels
Bullet Bills reappear in Super Mario Bros.: The Lost Levels when, once again, Bowser kidnaps Princess Peach. As most of the original enemies from Super Mario Bros. reappear in the remake, Bullet Bills do too. They can be defeated like they were in Super Mario Bros., with a jump, Koopa Shell, or Starman, and are still immune to flames. The Turtle Cannon in The Lost Levels are more strategically-placed than in the other game; on levels with Turtle Cannons, players have to watch where they jump very well.

In the SNES remake for Super Mario All-Stars, a fake Bowser is really a Bullet Bill in World C-4.

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' Airships. They can be defeated with a Jump, Koopa Shell, Starman, Hammer, tail attack, or a Bob-omb (on certain levels). Fire Flowers still do not affect them. A new type of Bullet Bill appears in this game, the Bull's-Eye Bill (originally "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
Although the Bullet Bill does not appear in Super Mario Land, a sub-species called Bullet Biff does appear.

Super Mario World
In Super Mario World, Bullet Bills once again make an appearance in Dinosaur Land after Bowser takes over it. Though, they're not common enemies, but their behavior changes slightly, as some levels feature areas where multiple Bullet Bills fly diagonally from four corners and, sometimes, vertically shot Bullet Bills appear, too. They are shot from Turtle Cannons, or, in some levels, they are shot from off-screen. Super Mario World also features the debuts of other subspecies of Bullet Bills such as Torpedo Ted, which are Bullet Bills that are launched from Torpedo Hasshadai underwater. The larger Banzai Bills also appear for the first time. Additionally, when the Special Zone is completed, horizontal-moving Bullet Bills turn into Pidgit Bills, which function identically but look like flying Pidgits. In Super Mario Advance 2, 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
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. They more resemble their larger sub-species, Banzai Bills.

Super Mario 64 / Super Mario 64 DS
In their first 3D appearance, Bullet Bills are only found in one location in Super Mario 64; in the level Whomp's Fortress. After Mario defeats the Whomp King, a Turtle Cannon appears at the top of the fortress. The Bullet Bills shot out home in on Mario and explode upon contact with him. Bullet Bills can not be defeated in this game. If Mario gets hit, he loses three wedges of health. Oddly enough, these Bullet Bills' faces resemble those of a Banzai Bill, but in the remake they look like the Bullet Bills from the other games.

In Super Mario 64 DS, there is another spot for Bullet Bills. It is at the 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, which sends them spinning backwards to eventually explode.

This is the first platforming Mario game where Bullet Bills cannot be jumped on.

Super Mario Sunshine
Between Super Mario 64 and 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 Teds, as opposed to the ones from Super Mario 64, which have an angry expression on their faces. In addition, the Bullet Bills in this game have an overall more robotic appearance, including a metallic exterior and google-eyes. In Super Mario Sunshine, Bullet Bills are fired from Cannons manned by Monty Moles at different points throughout the game, as well as by Bowser Jr. during the Mecha-Bowser boss fight and the final boss battle at the end.

In this game, a few variations of Bullet Bills appear, aside from the normal black variety. These include Purple Bullet Bills, Golden Bullet Bills, and Guided Bullet Bills. Every Bullet Bill variety can be dispelled simply by spraying them with water from F.L.U.D.D., which causes them to explode instantaneously. Most types of Bullet Bills release two coins when squirted except Golden Bullet Bills, which instead release eight coins. Purple Bullet Bills and Guided Bullet Bills home in on Mario, the former also featuring blinking red noses upon sight as opposed to the Bullet Bills that home in on Mario in Super Mario Galaxy and Super Mario Galaxy 2, which have blinking red eyes instead.

New Super Mario Bros.
In New Super Mario Bros., Bullet Bills appear in various levels, and are shot out of not only Bill Blasters, but also Bill Blaster Turrets. They appear in, World 5-4, World 6-1, (during the Monty Tank boss fight), World 7-5, and World 8-1. If the player jumps on them, they are defeated. They also can be defeated by hitting them with a Shell, or using a Starman or Mega Mushroom, and are again immune to fireballs. Banzai Bills return, and now their source is confirmed. In World 5-4, they fly out from somewhere off-screen rather than being fired from Bill Blasters.

Super Mario Galaxy
Bullet Bills reappear in Super Mario Galaxy. After they have been fired, if they spot the player, their eyes will turn red and they will 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 Teds 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 Bills also appear on Bowser's Galaxy Reactor, shot from Banzai Bill Cannons, but do not home in on the character.

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 Bills, which are indestructible and much bigger than even a Banzai Bill, as well as a homing Banzai Bill. Even though Bullet Bills are still fireproof, they can be frozen by an ice-ball from Ice or Penguin Mario. Unlike other flying enemies, Bullet Bills could be picked up and thrown while frozen. Bull's-Eye 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 and have an important role in World 6 as Enemy Courses. They also appear in several levels of World 7. In World 5-5, Bullet Bills fly out from somewhere off-screen instead of being fired from Bill Blasters.

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 Bills also appear, but Torpedo Teds do not.

Super Mario 3D Land
Bullet Bills reappear as enemies in Super Mario 3D Land. Similar to 2D Mario games, stomping on one will defeat it instantly, making this the first 3D Mario game in which this is possible, as will boomerang hits. After Mario tail whips a Bullet Bill when he is in a Tanooki Suit, it will change its angle after a spin and keep flying. Some Bullet Bills have Tanooki tails and are called Tail Bullet Bills. Like in the other 2D games, Bullet Bills are impervious to fireballs and only go in one direction.

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 will 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) and leave a trail of coins behind them. Jumping on the Bullet Bills themselves will 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.

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 Teds from Super Mario World also reappear. They now have a sub-species under the name Targeting Teds.

Super Mario 3D World
Bullet Bills return in Super Mario 3D World. 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 Bull's-Eye Bill.

Super Mario Maker / Super Mario Maker for Nintendo 3DS
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 Bills also reappear, and they are fired from Bull's-Eye Blasters.

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
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 which prevent them from being captured. They also appear in the Underground Caverns in the Moon Kingdom, where they wear white top hats. When they are fired from a Bill Blaster, they will 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 will explode 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.

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.

The Super Mario Bros. Super Show!
Bullet Bills make only one appearance in The Super Mario Bros. Super Show!, in the series finale of the show, "Robo Koopa", although Bullet Bill-like projectiles with faces are fired by a Snifit in the earlier episode "On Her Majesty's Sewer Service".

The Adventures of Super Mario Bros. 3
In The Adventures of Super Mario Bros. 3, Bullet Bills make a small appearance in the episode "Mush-Rumors", where they are fired from the Doomship alongside other munitions during the Koopa family's attack on a group of "aliens", who were actually a family of lost humans.

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 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.

Super Mario Bros. film
In the 1993 Super Mario Bros. film, miniature, non-explosive Bullet Bills (though they resemble more Banzai Bills) appear as the power source of the Thwomp Stomper boots used by Mario, Luigi and Big Bertha; a neon sign advertising a bar called "Bullet Bill's" can also be seen prominently displayed in Dinohattan throughout the film.

Mario's Time Machine
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
Hidden within the data of the Game Boy version of Yoshi is an unused Bullet Bill which would've functioned similar to the Goombas, Bloopers, Boos, and Piranha Plants in both that game and the NES version.

Yoshi's Safari
Bullet Bills are an enemy in Yoshi's Safari. They are present in a few levels. 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.

Super Mario World 2: Yoshi's Island / Yoshi's Island: Super Mario Advance 3
Bullet Bills chronologically first appear in Super Mario World 2: Yoshi's Island. The Bullet Bills in this game are colored green instead of black, and feature facial expressions as well. This game also introduces Bouncing Bullet Bills, which bounce and ricochet off walls after being fired. The Game Boy Advance version also adds Bull's-Eye Bills that home in on Yoshi while biting upon being shot out of their cannons.

The Bills in this game can be defeated by any way most enemies can be defeated. If Yoshi catches a 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.

Yoshi's Story
In Yoshi's Story, Bullet Bills follow the same pattern as in other games. However, this game introduces tongues for the mechanical irritants. The Turtle Cannons of this game are slightly different in appearance and the Bullet Bills are golden in color.

Yoshi's Woolly World / Poochy & 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. A new type of Bullet Bill known as Woollet Bills also appear. While the artwork depicts them nearly identical to their Super Mario World 2: Yoshi's Island appearance, they take their main series design in-game.

Super Mario RPG: Legend of the Seven Stars
In Super Mario RPG: Legend of the Seven Stars, Snifits, Blasters, and Big Berthas use Bullet Bills as a way to attack. This game also introduces Magnums, an alternate variety of Bullet Bills. Smithy uses Magnums as a way to attack. Magnums can defeat Mario or one of his partners with one hit.

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.

Bullet Bills are not hard to defeat at all, however, if a Bullet Bill bumps into Mario on the overworld, it will make the First Strike.

Gold Bullet Bills known as Bombshell Bills are also introduced in Paper Mario and are shot from Bombshell Bill Blasters. 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
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 Blasters. 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 Superguarded.

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 will cause Mario to lose 2 HP. They are one of the few enemies to have a similar appearance to the first three Paper Mario games. They were originally able to be battled, as evidenced by the text dump.

Paper Mario: Color Splash
While regular Bullet Bills from previous Paper Mario games do not appear in Paper Mario: Color Splash, they appear in their sprite forms in an underground area based on Super Mario Bros. 3, in the Green Energy Plant level. They are blasted from a Bill Blaster and drop multi-colored paint when stomped on.

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 that 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 Flying Goombas, and also features a Bullet Bill-like boat.

Mario Party 5
Bullet Bills appear in Mario Party 5 in the form of the 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.

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
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. When the player defeats him, Bullet Bill gives them the Gaddget Mini Soccer.

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
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 Blocks (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; if not, the player is eliminated. Also, 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
In Mario Party 9, Bullet Bills, along with Bull's-Eye Bills, appear in the minigame Billistics, the name being a pun on their name and "ballistics".

Super Smash Bros. Brawl
In Super Smash Bros. Brawl, Bullet Bills appear in a few stages of the Subspace Emissary, the adventure mode. They are seen flying straight from right to left, as they traditionally did in Mario platformers. Their size has been increased as well. Bullet Bills are affiliated with Bowser's forces and the Subspace Army. They cannot be stomped on like in the other games. In a cutscene, silver Bullet Bills are seen pursuing Diddy Kong and Donkey Kong, which explode after being defeated by the Kongs' attacks. Bullet Bills do sometimes home in on the character, and can be temporarily deflected.

Super Smash Bros. for Nintendo 3DS / Wii U
Bullet Bills appear in Super Smash Bros. for Nintendo 3DS and Super Smash Bros. for Wii U in two capacities: one as an item, and another as an enemy in the 3DS-exclusive mode, Smash Run. In the former case, once picked up and attempted to be used like any other item, players will instead turn into a Bullet Bill themselves and attack by ramming into opponents at full speed. Players explode if they hit a solid wall, including ceilings and floors. The resulting explosion deals even further damage to players and has a blast radius. In Smash Run, the Bullet Bill enemies attack by slowly flying toward the player and running into them to deal damage. Bullet Bills appear as an enemy in an event that deals with defeating as much enemies as players can. Here, they do not home into an opponent.

Super Smash Bros. Ultimate
In Super Smash Bros. Ultimate, in addition to reprising their role as items, a Bullet Bill appears as one of the drawings drawn by Nikki, an Assist Trophy. 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. In World of Light, the spirit is encountered on the Light Realm map; the spirit battle takes place on the Mushroom Kingdom stage and contains four Captain Falcons, with a Bullet Bill item tidal wave. The spirit can be enhanced to a Banzai Bill at level 99.

Mario Golf series
Bullet Bills appear in Mario Golf: Toadstool Tour being shot out of Bill Blasters resembling the Monty Mole's tanks 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.

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 countered with a jump. Mecha-Bloopers, which are found in Oho Ocean 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
In Mario & Luigi: Partners in Time, two sub-species of Shy Guy called Boom Guys and Elite Boom Guys 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. They can also be spotted during the boss fight against Swiggler in the Vim Factory, if the player looks closely when the Shroob UFOs 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.

In WarioWare: Twisted!, Bullet Bills make appearances with their Super Mario Bros. 3 sprites in the 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! 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, 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 microgame in WarioWare Gold.

Getting hit by a Bullet Bill causes Mario to lose ten seconds on the timer.

Mario Superstar Baseball
Bullet Bills are a special item in the Challenge Mode of Mario Superstar Baseball. When bought, it will allow Bowser to use his Power Shot, the Killer Ball, in a Challenge Mode game. The Bullet Bill is also Bowser and Bowser Jr.'s Power Shot. While pitching, when fired, a Bullet Bill will be launched at the batter. It will go slow at first, but when it gets close to the batter, it will fly in a loop. then zoom pass the batter. It can still be hit, however. While batting, when Bowser or Bowser Jr. hit the ball, they will launch a Bullet Bill across the field which, if caught, will push the catcher really far back. It stops working when it hits the ground. Bowser Jr.'s Bullet Bill wears a bandanna.

Mario Super Sluggers
Bullet Bills make a prominent appearance in Mario Super Sluggers. Bowser uses it as his pitching special. Also, a Bullet Bill made a small, yet extremely important cameo in the ending movie. When Mario and Donkey Kong are blasting Bob-ombs out of Mario Stadium, Wario and Waluigi shove a Bullet Bill into the Bob-omb cannon. Mario, too scared to move, watches in horror as it blasts toward him. Bowser comes out of nowhere, and smashes it back at them, blasting the two into the air. Bullet Bills also may occasionally pop up and fly around the outfield at Bowser Jr. Playroom, stunning players.

Super Princess Peach
When Bowser kidnaps Mario and Luigi and takes them to Vibe Island, Bullet Bills once again reappear. In Super Princess Peach, they can be defeated with a stomp, as usual. However, in this game, Bill Blasters do not appear; Bullet Bills come from somewhere off-screen. There is also a more dangerous type of Bullet Bills, known as Mad Bullet Bills, which are red and fly very fast. Banzai Bills and Torpedo Teds also appear with variations called Mad Banzai Bills and Glad Torpedo Teds, respectively. Pidgit Bills also make a cameo appearance where they are carrying color-flashing lettered signs spelling "NICE SHOT!!" after Peach swipes with Perry at Bowser and the Vibe Scepter over the horizon.

Mario Kart series
In the games Mario Kart DS, Mario Kart Wii, Mario Kart 7, Mario Kart 8, Mario Kart 8 Deluxe and Mario Kart Tour, the player can collect Bullet Bills as items. After activating the Bullet Bill, the player's entire kart will transform into a giant Bullet Bill, which will automatically rocket down the track on auto-pilot at very high speeds. The Bullet Bill is invincible, which allows the player to knock over any items, any course obstacles and any other drivers in the player's way, similarly to the Chain Chomp from Mario Kart: Double Dash!!. Damaged players by the Bullet Bill will also lose items in their possession. It will only last for a limited time, and can only be received by the racers in 6th-8th place in Mario Kart DS and Mario Kart 7, 8th-12th place in Mario Kart Wii and if they are far enough away from the leader in Mario Kart 8 and Mario Kart 8 Deluxe due to the new item system introduced in these games. However, if a Bullet Bill is used or reaches 1st place, then it quickly disappears, since it's supposed to only help last place racers, not lead racers.

It has been greatly praised due to its ability to rocket the player around the course, knocking any player it comes across. While moving, the Bullet Bill can be steered slightly. However, this item can be a disadvantage at times. For example, when racing on many of the trickier, narrower courses, the Bullet Bill can occasionally steer the player right up to the edge of the track, just before it wears off. This can often lead to the player falling into an abyss. In Mario Kart 7 onwards, Bullet Bills slow down when nearing the end of its limit - which makes it less likely for a player to be thrown off the course.

Players who are under the effects of the Mega Mushroom can be knocked back by this item. However, players who are invincible due to a Star or a Boo, are not affected when a Bullet Bill collides with them. Also, there cannot be two characters with Bullet Bills at one time in a race except in Mario Kart 8 and Mario Kart 8 Deluxe, where up to 3 characters can have them at the same time.

Bullet Bills are also an obstacle in the Airship Fortress track in Mario Kart DS, but are replaced with Banzai Bills in Mario Kart 7. Bowser Jr.'s kart in Mario Kart: Double Dash!! takes the form of a Bullet Bill and is called the Bullet Blaster. There is also a bike for small-sized characters in Mario Kart Wii called the Bullet Bike, which also resembles a Bullet Bill. Mario Kart 8 shows that Bullet Bill's eyes glow in the dark, as seen in courses without light, such as Twisted Mansion. Bullet Bills also have a sponsor in Mario Kart 8 and Mario Kart 8 Deluxe named after them, Bullet Bill Speed Trial.

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.

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 will sometimes 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 Flowers. Alternatively, giving a Bullet Bull 3 Goomba Coins will transform it into a mash-up enemy, called Bullet Bill & Goomba (a solo Goomba on a Bullet Bill blaster). Six more Goomba Coins will transform 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.

Alleyway

Characteristics and traits
Bullet Bills are black anthropomorphic missile-like creatures with white arms and eyes with black pupils/irises. Bullet Bills have engines at their backsides, thus allowing them to travel in the air. In most games, they can be defeated by simply jumping on them, though other games make them more resilient. Like other enemies, Bullet Bills have had varying appearances. In the earlier Mario games, Bullet Bills had a slightly brown hue, though this was due to color limitations. In Super Mario 64, Bullet Bills are physically larger than in other games, and resemble Banzai Bills, with features such as a shark-like mouth with a row of teeth, yet a lack of arms. The Yoshi's Island games give Bullet Bills yellow or green color schemes, while appearing similar to Banzai Bills. Super Mario Sunshine drastically alters Bullet Bills' appearance, due to giving them a slimmer shape in the vein of Torpedo Teds; they also smile in this game, and have bigger eyes. In the DIC Entertainment Mario cartoons, Bullet Bills appear unintentionally similar to Banzai Bills, though they are colored gray; additionally, some of them are sentient, and possess the ability to speak. In early artworks, they are depicted with a mouth.

In most games, Bullet Bills simply fly around without targeting a victim, usually being launched from Bill Blasters. 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 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".
