Ar

Ar is the main villain of Tetra Again and the Tetris Returns story of Puyo Puyo 8. He was the former Tetris King before Ex, Tee and Yeu.

Personality
A long time ago, Ar was actually a benevolent Tetris King. But when he was defeated by Ex, he slowly went insane as he craved becoming a Tetris King once more. Eventually, his only goal was to defeat Ex and become the king, but he could never manage it. He eventually grew disgusted by Ex and hated him with all his might. Even today, he hungers for the title and obsesses for Tee because of it.

History
Ar was the Tetris King a very long time ago, before Ex and Tee took the title. But one day, he was challenged by Ex. Ar took his challenge and they battled for the title. Ex defeated him and took his title. He was enraged by him, and he vowed to challenge him to a rematch when he got stronger. He trained intensely for months, and finally confronted Ex once more. To his chagrin, he was triumphed over once more. From this day forth, Ar grew insane, longing to regain the title, and challenging Ex over and over again hoping one day he'd get a lucky run. But he never did. Even when Ex left to control the dimensional balance, he still tried to take the title from Tee, but it never worked.

During the events of Puyo Puyo Tetris, he used his power to brainwash Feli, Raffina and Rulue, in hopes that one of them would be able to take down Tee, but they were all saved before then.

Ex
Ar really hates Ex. He feels that Ex ruined his life, and he tried his hardest to get revenge on him. Even when Ex passed his title to Tee, Ar still despises him.

Tee
Just like Ex, Ar started off hating Tee for being the Tetris King. However, he eventually grew to be obsessed with him, trying his hardest to either win against him or to win him over. He fails every time, but he still feels there's a chance. Tee, however, is incredibly uncomfortable with him.
