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.

Meanwhile, Marucho decides to have a battle to make up for Dan having to sit out, so he fights against Jack of Team Anubias. He and Tristar struggle to win against Jack and his Guardian Bakugan, Aquos Krakenoid. Meanwhile, Dan and Drago locate an abandoned arena to use as a training ground, but shortly after, a mysterious Mechtogan that calls himself Zenthon appears and wreaks havoc on the arena. Dan and Drago try to defeat it, but it eventually flies away and reappears to interfere with Marucho and Jack's battle and devastating the arena. Anubias and Sellon team up to fight Zenthon but struggle to defeat it, not even managing to land a hit. Eventually, however, Zenthon flies off and Anubias and Sellon part ways. Marucho and Shun then speculate that, since Zenthon has the same destructive power as Drago, they may be connected. Meanwhile, the masked man, whose named is officially revealed to be Mag Mel, is trying to break free of his prison, but requires more energy from Dan and Drago to do so. One of his hooded servants (who looks a lot like Sellon) informs him of the Mechtogan attack.
