ren is a darkus brawler disguised as a gundalian, he was sent by emperor barodius to find the strongest brawlers to help defeat Neathia and to find the DNA code. Ren comes from the underground world of Gundalia, where he was kept by Emperor Barodius' family because he possesses a dark Bakugan with a very powerful ability. Due to his knowledge of the Gundalians, Ren will prove a valuable asset in defeating them. He will probably be the kind of rival Ace was for Dan. Also, once Fabia arrives, he will no doubt create friction amongst the Brawlers.
