Koopa Troopa

Koopa Troopas are a fictional turtle-like race of characters from the Mario media franchise. They are commonly referred to as Koopas, a more broad classification of creatures that includes Bowser, his Koopalings, and Lakitu. Predecessors to Koopa Troopas, Shellcreepers, first appeared in the 1983 game Mario Bros., while Koopa Troopas themselves debuted two years later in Super Mario Bros. (1985). Koopa Troopas are a common staple in most Super Mario and spinoff games. When defeated, they may flee from or retreat inside their shells, which can usually be used as weapons. Koopa shells are a recurring weapon in the franchise, particularly popularized in the Mario Kart series, in which they can be fired as projectiles against other racers. Despite making up the bulk of Bowser's army, Koopa Troopas are often shown to be peaceful, sometimes even teaming up with protagonist Mario.
