Dan, however, shrugs it off and says he'll get Drago's powers under control, but secretly, he's extremely nervous about the amount of power Drago unleashed, and the two of them decide to go train to get it under control. 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 Trister struggle to win against Jack and his Guardian Partner 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. He is astounded that Drago has that sort of power and tries to absorb more energy from Dan and Drago and begins to break free.

He tells the Brawlers this, then declares that he will use his psychic link to battle Mag Mel. Shun and Marucho think it is too dangerous, but Dan argues that it is their only chance to stop him. Then Soon and Chris are mourning the loss of Sellon, when a Flash Ingram attacks. They are then saved by Noah who is using his new Guardian Partner Bakugan [[Subterra]] [[Ziperator]]. Then the whole of Team Anubias shows up, all with Ziperators as their Guardian Partner Bakugan. Ben has a [[Pyrus (Legacy)|Pyrus]], Jack has an [[Aquos (Legacy)|Aquos]] and Robin has a [[Ventus (Legacy)|Ventus]]. When Soon questions why they still fight when Anubias is gone, they reply that they fought under him, but not for him. Meanwhile, Dan links up with Mag Mel and Dan and Drago find themselves in a dark reverse version of Bakugan Interspace. Mag Mel reveals himself and they begin to fight. They quickly summon their Mechtogan and they all fight their counterparts. The battlers then summon energy blades corresponding to their attributes. Meanwhile, Chris and Soon are sulking outside Brawler HQ. and are attacked by more Chaos Bakugan. They are saved by the Brawlers and Team Anubias, who are protecting Dan and Drago. Chris and Soon soon join in with their new Guardians Darkus [[Clawsaurus]] and [[Haos (Legacy)|Haos]] [[Spidaro]]. Marucho is trying to get a message out to the outside world, when Dylan offers to help. Meanwhile, Dan smashes off part of Mag Mel's mask revealing him to be Barodius. Razenoid then confesses to have been previously [[Dharak]]. They say that Code Eve imprisoned them in the reverse dimension. They then summon their Mechtogan Titans and continue the fight. After a huge display of power, they lose the link, in Brawler HQ. They tell all of their allies their findings. Dylan then helps Marucho talk to his father and Marucho tells his father his plan.
