Bakugan Battle Brawlers - Season 4 Episode 2

After Dan's battle with Ben, Marucho and Shun talk to Dan about having Drago sit out for a while. 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 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. He is astounded that Drago has that sort of power and tries to absorb more energy from his Darkas Dragonoid (or possibly Dragon and Dan) and begins to break free.
