Enemy Infiltration

The episode begins with Skytruss and Orbeum investigating on Wiseman's hideout, having been transported there by Shun when he threw them two episodes earlier. They then discover a secret room after wandering around for a while. Meanwhile, Wiseman reveals to the Nonets that the Mechtogan are now fully ressurrected except for Coredegon; as Wiseman states he is saving him for last. As Skytruss and Orbeum send out a message to the Brawlers about Wiseman's hideout, Balista vows to find out Wiseman's true identity. Meanwhile, the Brawlers learn of Wiseman's hideout and they head there to take down Wiseman for good. Back at Wiseman's hideout, Skytruss and Orbeum face off against Stronk and Spatterix, but are eventually defeated and recovered by Dan, Marucho, and Shun. The Mechtogan except Coredegon appear and a huge battle ensues. Meanwhile, Balista tries to awaken Gunz from his prison, but is unsuccessful. Wiseman then appears and prepares to punish Balista for "putting his nose in other people's business". Balista demands Wiseman to reveal his true identity. Wiseman does so and presumably kills Balista in the process. Outside the cave, the Brawlers combine their Bakugan, in hopes of defeating the Mechtogan, but are overpowered and sent off a cliff. The episode then ends with Gunz finally awakening.
