From the Super Mario Wiki
“King of Speed”
Bullet Bills are bullet-like projectiles with menacing looks and arms that appear in the Mario series. 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, Bullet Bills have had the ability to home in on Mario, also like a missile. These enemies can be found throughout many of the classic Mario games and in newer games, where they 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 series
 Super Mario Bros.
When the Mushroom Kingdom is overrun by Bowser in Super Mario Bros., Bullet Bills are Bowser's prime ammunition. Bullet Bills first appear in World 5-1. They are usually shot from a large cannon (the Bill Blaster), though are sometimes shot from off-screen, and fly in a straight line. The Bill Blasters are placed very strategically in almost all levels, being wherever Mario is. One of the most frustrating places where they are placed is flat on the ground, so even a normal-sized Mario has to jump to avoid them. 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 their 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.
 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 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 when Dinosaur Land is under the tyranny of Bowser. Though their appearances are scarce, their behavior changes slightly, as some levels feature areas where multiple Bullet Bills fly diagonally from four corners, and sometimes vertically shot bills appear, too. They are shot from Bill Blasters, or, in some levels, they are shot from random locations 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, all of the horizontally fired Bullet Bills turn into Pidgit 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 Missile 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 a few coins when squirted, though gold Bullet Bills release 8 coins instead of just two. The Missile 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, as usual, shot out of Bill Blasters. They appear in World 2-Castle, 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 gigantics, 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 Blasters, 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 and Banzai Bill Blasters also reappear. This game also introduces a new sub-species, called the King Bill, which is indestructible and much bigger than even a Banzai Bill. Even though Bullet Bills are still fire-proof, they can be frozen by an iceball from 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 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 in this game.
 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 anymore 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 Land series
 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. Torpedo Teds also make their second appearance in this game.
 DIC Cartoons
 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".

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 series
 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.
 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 Bill Blasters of this game are slightly different in appearance and the Bullet Bills are golden in this game.

 Paper Mario series
 Paper Mario
Normal Bullet Bills are in Paper Mario when, once again, Bowser kidnaps Peach. These attack by ramming into Mario, defeating themselves but causing a lot of damage to Mario. There is an infinite supply shot from Bill Blasters. They can be found in the Koopa Bros. Fortress, right before the Koopa Bros. were fought.
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 the Bullet Bills from this game, but have more HP, do more damage, and have 1 defense.

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 Bullet 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 Bullet Bill Blasters mounted at the platforms on the airship's exterior.

 Mario Power Tennis
In Mario Power Tennis, in a minigame, they are fired by a Mecha Bowser 2.0.
 Mario Baseball series
 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.

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 and Mario Kart 7, 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, knocking over any enemies or projectiles in the player's way, similarly to the Chain Chomp from Mario Kart: Double Dash!!. 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, and 8th-12th place in Mario Kart Wii.
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.
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 Strikers Charged
A Bullet Bill makes a short appearance in Mario Strikers Charged. It appears as the Skillshot of Shy Guy known as Bullet Bill Blast.
