Bakugan Battle Brawlers - Season 4 Episode 1 Interspace Showdown
8.30 25 minutes It has been one year since the events in Gundalia, and Bakugan Interspace has grown greatly. Marucho has teamed up with a Bakugan from Gundalia, Tristar, while Shun's partner is Taylean, a Bakugan from Neathia. After winning a battle, Dan and Drago learn that there have been two groups of battlers, Team Sellon and Team Anubias who have risen to high ranks not far behind Dan. Dan has a nightmare the following night in which a mysterious entity demands that Dan give him something. Drago, who also had a vision of a bakugan during the earlier battle, speculates that the two events may be related. Unconcerned by this deadly and skilled competition, Dan challenges Ben, a member of Team Anubias to a brawl. While Dan and Drago initially struggle due to the battle environment and faced against two bakugan. They struggle and just before they are about to lose, the entity again appears to Dan (Drago sees the image of the bakugan) and tells him to release his hidden power and destroy ben and his bakugan, also giving him all the power. They ultimately pull out a win after realeasing that power. However, Drago is unable to control the power nearly destroying the arena. This leaves Dan and Drago to wonder about the dangers of this latest discovery and if they are a threat.
