When defeated, Koopas may flee from or retreat inside their shells, which can then usually be used as weapons.  First appearing in the 1985 Nintendo Entertainment System game "Super Mario Bros.", they are among the oldest recurring enemies in the series, and have appeared in some form in all of the main games, and most of the spin-off games.  Shellcreepers are a different species, according to their trophy in "Super Smash Bros. for Nintendo 3DS and Wii U".  Koopa shells are a recurring weapon in the series, particularly popularized in the "Mario Kart" series, in which they can be fired as projectiles against other racers.
