He along with Toad is placed under the category 'The Small Guys'. Koopa Troopa makes his Mario Kart debut in the series' first installment, Super Mario Kart, as a lightweight racer along with Princess Peach, Yoshi, and Toad. Koopa Troopa is unavailable in the Mario Kart Arcade GP series.
Koopa Troopa is mad that other racers use Koopas as items. He has bright, white eyes, and he is encased in a green shell.
His legs, arms, tail, and head are all yellow in color. However, some Koopas aid Mario on his quest, like Koopa The Quick in Super Mario 64 and Super Mario 64 DS. Koopa Troopa is one of Bowser's allies who tries to stop Mario in his quest to save Princess Peach.
