Enemy Allies.The episode begins with Kato checking that all the Brawlers are asleep. Only Mira, who is working on some new Battle Suits for the Brawlers' Bakugan, is still awake. The next day, Julie and a camera man arrive at the HQ for an interview report. She then asks Dan, Marucho and Shun questions about Wiseman but their Bakugan pull her away. Mira then enters, saying she has finished the Battle Suits but before finishing explaining about their Battle Suits she faints but Dan catches her. She later wakes up in front of the Brawlers, Dan says to rest and she gets upset, Kato then asks her to call him if she needs anything but she then stops him and asks him a favour. The Brawlers are then sitting down when Kato then tells Marucho that he is going to get Mira something and leaves in Marucho's ship. Between this time Wiseman and Betadron talk about resummoning Coredegon and the others. They later appear in a park and Julie gets a call from her boss saying that Wiseman is back and she later hides in a bush whilst the Brawlers confront Wiseman. The Brawlers seem to be gaining the upper hand until the Nonet Bakugan generate enough energy to summon the Mechtogan to fight the Brawlers. They soon integrate into Mechtavius Destroyer and the Brawlers combine into Betakor and Magmafury but are defeated and Dan is knocked out. Kato is soon arriving with someone the Brawlers know well. Shun, Marucho, Reptak and Drago try and fail to wake up Dan but soon after a voice wakes him up Dan then realizes its Runo who Mira told Kato to go get because she knows Vestal Technology and sends the Battle Suits to the Brawlers. The Brawlers then gain the advantage and beat the Nonet Bakugan and Mechtavius Destroyer. After that, Runo is welcomed back to the team.
