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 spin-off games.
