Gunz Lives is the 40th episode of Bakugan: Mechtanium Surge. It aired on December 10, 2011.
Gunz has now finally woken up but he doesn't remember anything since his battle with Dan. Once he broke free from the vines, he went to find a way to escape from Wiseman's base. Wiseman and Worton were discussing if the Brawlers were still alive or not. After that, Worton asked Wiseman if he knew where Balista was, but he told him that he didn't know.
Wiseman appeared before Gunz, revealed his face, and told Gunz how he was created from his jealousy of Dan. After that, he let Gunz look around to find Reptak. Meanwhile, Dan, Marucho, and Shun were in Kato's submarine after having fallen off a cliff. Reptak explained that Gunz was willing to fight Dan as a rookie, but when he lost, he got very mad, but Reptak encouraged him that no matter what, if they just train hard, they will win.
Once his story was over, Mira announced that she made duplicates of the Battle Suits Wiseman stole. Once they were geared up and ready to fight, they headed off to the island. After Gunz took a drink of water on a fountain, he saw Reptak and called for him but they thought he is Wiseman, since Wiseman looks like Gunz. Wiseman then shows up out of nowhere and teleported Gunz to his base. Shocked by this, the Brawlers were enraged for Wiseman pretending to be Gunz. Wiseman then threw Spatterix, Stronk, and Worton, including the Battle Suits that he stole. Later on, he sends out Betadron, Kodokor, Mutabrid, and Tremblar. After a long battle, Wiseman had enough energy, and revealed his true identity, Coredegon. Coredegon then shot a wave that defeated all the Brawlers' Bakugan, and revealed that he was using the Nonets all this time, and his true plan was to take over the world.
