Bullet Bills are missile-like projectiles with menacing looks and arms that appear in the Mario series. They have been enemies of Mario since their debut in Super Mario Bros.. 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. Ever since Super Mario 64, Bullet Bills have had the ability to home in on Mario, also like a missile. They are shot out of Bill Blasters, and are usually under Bowser's control. However, when players stand on or walk so close that they touch the Bill Blaster the Bullet Bills are shooting from, the Bill Blaster will not shoot the Bullet Bills.
