Koopa Troopas, or just simply Koopas, known in Japan as Nokonoko (ノコノコ ) , are a fictional race of turtle or tortoise-like creatures from the "Mario" series, as well as its sister "Yoshi" series.
 Although the term 'Koopa' is a blanket term for the entire species of anthropomorphic turtles in the series, to which creatures such as Lakitu, Hammer Bros. and even Bowser belong, the term is often used to refer colloquially to this particular enemy.
 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.
 When defeated, Koopas may flee from or retreat inside their shells, which can then usually be used as weapons.
 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.
 Despite making up the bulk of Bowser's army, known as the "Koopa Troop", Koopas as a species are often shown to be peaceful, some even teaming up with Mario.
 An undead Koopa Troopa becomes a Dry Bones.
