In Mario Kart 64, the players can choose any one of eight unique characters to operate their kart. Koopa Troopa and Donkey Kong Junior, both of whom appeared in Super Mario Kart, did not return for Mario Kart 64, and were replaced by Donkey Kong and Wario. The characters are divided into three categories. The 'Lightweights' include Peach, Yoshi and Toad. These characters are favored for their quick acceleration. The 'Heavyweights' include Wario, Bowser, and Donkey Kong. These characters are favored for their responsive steering. The 'Middleweights', Mario and Luigi, are balanced characters.
