Ai, as he appears in Puyo Puyo Tetris.
|Only appears in||Puyo Puyo Tetris|
Ai is a character in Puyo Puyo Tetris. He is the chief engineer on the Spaceship Tetra. Normally a knowledgeable gentleman, he breaks into tears and a dog-like whimper when panicking.
Like the other Tetris-based characters, he is named after a Tetrimino. The namesake Tetrimino motif is visible on his boots.
- Like Risukuma, his spell clips consist of a phrase in different languages--in his case, "Beautiful".
- He along with the rest of the characters from Puyo Puyo Tetris are the only SEGA-era characters that make no appearance in Puyo Puyo!! Quest.
