Bakugan Battle Brawlers (2007) : 2x24

With Mira returned, and the Resistance reunited, Dan and the others head for Prince Hydron's sky palace to free Skyress, Tigrerra, Preyas, Gorem, and Hydranoid from captivity. But before they can even get close enough, Hydron activates another dimension controller, causing the Bakugan to turn back into ball form. Quickly thinking, Shun grabs Mira and Marucho and grapples onto the top of a rising elevator and to safety. Down below, Dan, Baron, and Ace are saved just in time by their Bakugan. But before they can think of a way to get up to the palace, Spectra and Cyber Helios challenge them to a battle. As Dan and Drago struggle to fight back against the power Helios now possesses, Shun, Marucho, and Mira have managed to sneak into Hydron's throne room and discover the bronze statues of the five other Guardian Bakugan, just before meeting face to face with Prince Hydron himself. Meanwhile, Mylene, Volt, and Shadow order Dr. Clay to give them an escape off of New Vestroia, as the energy from the battle between Cyber Helios and Drago could destroy everything around them. Dr. Clay at first refuses saying that it would be treason, when Shadow reminds him he works for the Vexos now. Gus overhears their plan, but before he can warn Spectra, Lync hits him over the head and knocks him into a room, locking Gus inside so he can't tell Spectra of their plan. Back with Dan and Drago, Spectra, having underestimated the perfect core's power, has used the mechanical Bakugan he has to make Maxus Helios, a Bakugan who has all six attributes. Dan tries to use a combination of Ability Cards that tap into the Perfect Core's power, but still can't match Maxus Helios's power. Dan realizes he has no choice but to use the Bakugan he got from his battle with Mira to make Maxus Dragonoid, just as Spectra has again used the other six mechanical Bakugan on Helios. The two Bakugan face each other, preparing for the final battle.
