Mira and Spectra meet with Prince Hydron, who shows her his collection and later receives a message from his father, who is angered by the destruction of the other two controllers. Hydron then orders Mylene to divide and conquer the Resistance, since she has shown that they are weaker on their own and orders Lync to keep an eye on Spectra and make sure that his new mechanical bakugan is ready for battle. The Resistance arrives and Ace and Baron explain that the controller is underground and is the most powerful. They all head in but encounter Volt. Baron deals with Volt while the others proceed discovering that Gamma City is not a real city but a research facility. All of a sudden, Shadow and Mylene appear and Shun and Marucho step in to battle. Spectra takes Mira to see a team of special mechanical bakugan that he and Dr. Clay had designed themselves that were intended for Hydron but he intends to make certain that they only obey him. Spectra then orders Mira and Gus to use the bakugan to battle Dan and Ace to collect data on Drago and Percival. Meanwhile, the others gain the upper hand against the Vexos. Dan and Ace continue to the controller but encounter Gus and Mira. Ace is shocked that Mira has truly betrayed them and Gus orders Mira to prove that she is loyal to Spectra.
