Bakugan Battle Brawlers (2007) : 2x52

With the battle against the Alternative pressing on, Hydron shows up to lend a hand. Meanwhile, Prof. Clay receives a video transmisson from a faraway world just as Mira and Keith arrive to make one final appeal. Once the brawlers realize Mira and Keith are missing, they deduce that the siblings may have found a way inside, so Dan uses Jetkor to blast a hole in the Alternative while Gus and Marucho stay behind to guard the rear. Gus and Vulcan are nearly beaten when Hydron steps in and saves him. Shun, having suggested to find the Power Reactor of the Alternative AND having memorized the blueprints of the machine, leads the Resistance through the Alternative. However, they are all quickly caught in a trap against four mysterious bakugan, unrecognized by Drago. While Mira pleads with her father to abandon his evil plans with Zenoheld, Dan and the others destroy the four unknown Bakugan as well as the Power Reactor. As they make their escape, Prof. Clay saves Mira from falling debris, but is trapped on the ship and Hydron captures his father, forcing them both to "go down with the ship." Prof. Clay returns to this computer and finds that the video he received depicts Bakugan in war. The Resistance go their separate ways as Keith and Gus thank Dan for showing them the error of their ways. 3 weeks later, Marucho has completely repaired Bakugan Interspace and uses Akwimos to test it while Shun uses Hawktor and Dan sticks with Drago. Then, they are approached by a boy named Ren who asks them if they're the Brawlers.
