When the Brawlers discover that the Gundalians are inside Bakugan Interspace "recruiting", more like kidnapping, more Battlers to join their cause, they race to the scene to confront them. Soon, two separate battles break out, and Ren flees in the confusion. While the Brawlers fight bravely to protect the other Battlers from falling victim to the Gundalian invaders, Ren is elsewhere, hatching an even more sinister plot; one that will see the Gundalians seizing control of Bakugan Interspace and ejecting the Brawlers forever.
