Preyas is a chameleon-like Bakugan with a strong loyalty to Marucho. His greatest strength is his ability to change his molecular structure, allowing him to take on characteristics of all the six attributes. Even though he has a menacing appearance, he is quiet shy and comical. Small in comparison to the other Bakugan, Preyas sure makes up for it in speed. He likes to fool around in battle and tell jokes. He evolves into Preyas II, Angelo/Diablo Preyas. In the Bakugan Video Game, Preyas can only be Aquos, Subterra and Darkus but unlike the anime, it is completely random of which attribute he becomes.
