Meanwhile, the problem goes worse with the Brawlers in the Doom Dimension, not just on how to escape, but also Betadron and Gunz going into the Doom Dimension and challenging Dan Kuso and Drago in a battle. Betadron was still obsessed with taking down Drago and Gunz has revenge to Dan because of his partner, Reptak, was now battling with Dan. Dan tries to convince Gunz that Coredegon had deceived them, but the later refuses to believe it. After an intense battle, Dan and Drago emerge victorious, and Gunz decides to put his old life behind him and start anew with Reptak, discarding his identity as Wiseman 2.0. Betadron also joins the Brawlers. Worton then appears and informs them that Mechtavius Destroyer must be stopped before it's too late.
