Interspace Showdown.One whole year has passed after defeating Barodius and the Twelve Orders, Dan, Marucho and Shun have managed to rebuild Bakugan Interspace and expand it. The episode begins, with Dan battling two Subterra and Darkus brawlers in Interspace with Marucho and Shun observing the battle. Marucho's new Guardian Bakugan, Aquos Trister, complains about not being able to battle after leaving Gundalia to team up with him. Shun's new partner, Ventus Taylean, tries to tell Trister to be patient but the two end up squabbling. Meanwhile, Dan and Drago are about to finish off their opponents with Dragon Strength but Drago has a vision of a strange Bakugan that makes him miss. But after attacking them once again, he finishes them off with a few blows. After the battle, the Brawlers observe two rival teams battling, Team Anubias and Team Sellon. Ever since they appeared in Interspace, they have become among the top ranked battlers, just below Dan and Drago. Suddenly Team Anubias appears and starts trash talking about the Brawlers, almost to the point of battling each other. However their rivalry is interrupted by a sleazy dealer named Dylan who tries to get them to buy his stuff and cause both teams to leave...
