Ren Krawler
A Gundalian operative sent to Earth as a spy, Ren was tasked by Emperor Barodius with recruiting the strongest brawlers and obtaining the Neathian DNA code. He comes from Gundalia's underground and was specifically raised by Barodius' family because of his partnership with Darkus Linehalt, a Bakugan with formidable dark powers. His Battle Gear is Boomix.
Ren's loyalty to Barodius eventually wavered after Dan confronted him with the truth: Barodius had actually banished Ren's own people. This revelation forced Ren to reconsider whose side he was really on. The turning point came when Linehalt was pushed to unleash its forbidden power—a moment that shook even Ren. Fabia, however, remained skeptical of his sudden change of heart and demanded a one-on-one battle to determine whether Ren's transformation was genuine.
