Koopa's first appearance in a game as a playable character was Super Mario Kart, as the lightest of four weight classes. He would later appear in [[Mario Kart Double Dash!!] as a lightweight paired with Paratroopa. His special items are the triple shells. He would also have an appearance as a driver in Mario Kart Wii as a lightweight. In Super Mario Kart, Koopa has two courses, both named Koopa Beach.
