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. They also have increasingly been items, mostly in the Mario Kart series. Other games depict them as sentient being 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 cannon (the Bill Blaster), 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 Fire 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 Blasters in The Lost Levels are even better-placed than in the other game; on levels with Bill Blasters, players have to watch where they jump very well.

In the SNES remake for Super Mario All-Stars, a Bowser Impostor is really a Bullet Bill in World C-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 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 Bill Blasters, 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 Skull Boxes underwater. The larger Banzai Bills also appear for the first time. Additionally, when the Special World 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 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 Bill Blaster 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. 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. The bullet bills here resemble Torpedo Teds. One of the major changes includes the fact that the Bullet Bills in this game are smiling, 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 specific sub-species of Bullet Bills appear, aside from the normal black variety. These sub-species include Blue Bullet Bills, Crazy Bullet Bills, gold Bullet Bills, and purple Bull's-Eye 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. Each type of Bullet Bill releases 2 coins when squirted, though gold Bullet Bills release 8 coins instead of just two. The Bull's-Eye Bills that home in on Mario after they are fired, feature blinking red noses, 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. During the final Boss battle, there are blue and red-nosed Bullet Bills that chase Mario.

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, 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. A gigantic, snifit-like robot named Megaleg has to be defeated 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 they 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 re-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 pack Coin Challenge Pack B.

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
Bullet Bills reappear in Super Mario Maker 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 their own Bill Blasters.

Super Mario Odyssey
Bullet Bills and Bill Blasters will appear in the upcoming Nintendo Switch game, Super Mario Odyssey. They appear in a temple-like level.

Super Mario Land
Although the Bullet Bill doesn't appear in Super Mario Land, a sub-species called Bullet Biff does appear. Bullet Biffs resemble Super Mario Sunshine Bullet Bills with an added feature of a Rocket Engine.

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 Bill Blasters. 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.

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 Bill Blaster 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.

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 Bill blasters 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 added Biting Bullet Bills that home in on Yoshi 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.

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. Bombshell Bills also reappear in this game.

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 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.

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 Bullet Bills at the player. 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.

Super Smash Bros. for Nintendo 3DS / Wii U
Bullet Bills appear in Super Smash Bros. for Nintendo 3DS / 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.

Mario Power Tennis
In Mario Power Tennis, in a minigame, they are fired by Mecha Bowser.

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 the Warios, blasting them 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.

Mario Kart series
In the games Mario Kart DS, Mario Kart Wii, Mario Kart 7 and Mario Kart 8, 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 totally 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, which increases the farther behind the player is in the race, 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 due to the new item system introduced in this game.

It has been greatly praised due to its ability to rocket the player around the course, knocking any player it comes across without having to steer. 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 and Mario Kart 8 Bullet Bills slow down when nearing the end of it's lifespan - 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, where up to 3 characters can have them at the same time. Multiple Bullet Bills can appear during the race if got at different times.

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 Toad's Turnpike.

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 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.

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.

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

Alleyway
