Preyas (Japanese Version: Predator (プレデター, Puredetā?)) is a humanoid chameleon-like Bakugan, who is able to change his attribute. Initially, Preyas has the Aquos attribute but can change into Darkus or Subterra, then back to Aquos. He is Marucho Marukura's Guardian Bakugan in Bakugan Battle Brawlers and in Bakugan: New Vestroia from episode 26. 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.
