Evil Master Beast

The Evil Master Beast was the main anatogonist of the video game One Piece: Unlimited Adventure. Like many of his minions, the Evil Master Beast battled using a conglomeration of special moves stolen from other characters. He could use Ace's Flame Fist, Enel's Judgment, Aokiji's Ice Age, Don Krieg's MH5, Crocodile's Sandstorm, and Rob Lucci's Rokuougun. He also used an attack involving highly potent balls of energy which followed the player around the arena.

Story
The Evil Master Beast is the "true" form of the Evil Guardian that attacked Popora's island, having gained greater powers by mimicking the Straw Hats' memories. He is the final boss of One Piece: Unlimited Adventure. After his defeat, the end cutscenes and credits roll, and he is unlocked in VS Mode along with the Evil Guardian.
