AiAi (アイアイ?) is the main character in Super Monkey Ball. He is obsessed with bananas and likes fighting evil on the island, alongside his friends and family. Although he may seem crazy for bananas, AiAi really does care about his friends and family and would do almost anything for them. He has appeared several times in the Sonic the Hedgehog series.


AiAi has similar traits to a spider monkey. His tail is short and stubby. He has an orange shirt with the letter A on it. He has brown eyes, a small scruff of hair, and rounded ears that stick out of his head. Later games updated his look, giving him a blue backpack, red oval shaped cheeks, a cat-like smile and a much softer appearance overall.

Game appearances

AiAi appears in Sega Superstars with a minigame based on his own series of games where the player has to use their own body to move him around and get to the end in time, like his own games.

Sonic & All-Stars Racing Transformed

The cheeky little monkey appears in Sonic & All-Stars Racing Transformed again driving his vehicle from the previous game, but redesigned to look more like a conventional race car, like a dragster. For transformations, the car loses its wheels and sprouts banana-like structures to become a boat. Then it uses the same banana structures, but they stick from the bottom of the vehicle in a upside-down 'V' and reveals a booster to make it a jet.

Sonic Riders

AiAi appears in Sonic Riders as an unlockable character. Oddly enough, he is a Power-type character, and as such, pushes lighter characters around easily. However, due to his small posture, he is easily pushed around just as much.

SEGA Heroes

Other game appearances

A costume of AiAi is unlockable in the game with the bonus edition of Sonic Forces.

In other media

Archie Comics

AiAi in the Archie Comics.
