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.
