Dan and Ace engage Mira and Gus in battle against their mechanical bakugan. During the battle, Mira seems to be purposely losing. Baron, Shun and Marucho have beaten the other Vexos and arrive in time to see Dan and Ace win, claiming the mechanical Maxus Dragonoid traps.(Baron beats Volt; Shun & Marucho beat Shadow and Mylene). Spectra is furious at Mira's betrayal, claiming that they have even stronger bakugan than the ones Gus and Mira used. Mira apologizes for betraying the Resistance, but they welcome her back into the group otherwise. They next head to the Vestal Palace to free all the original Guardian Bakugan and save New Vestroia for good.
