The episode starts with the brawlers discussing Wiseman and his Nonet Bakugan. In the middle of the discussion, Reptak leaves, as he was really worried by his missing partner, Gunz. Then, after reassuring Reptak that they would find him, Dan, Drago, and Reptak start to ask the people of Bakugan City if they had seen Gunz, but no one was seen him. However, Reptak hears the voice of Gunz and he saw him in a crowd of people. They followed him and go into the construction site. There, Wiseman was found, and challenges Dan into battle and he throw Betadron, Mutabrid, and Kodokor. Dan throws Drago and start the fight, but he loses in the first round. At the middle of the battle, Reptak questions if he was Gunz, but he challenges Dan to remove his mask on his own. Dan throws Reptak and fight with Drago, but they are still defeated. So Mira say to Dan to send battle suits to them and use Doomtronic and they defeat them easily. But Betadron along with his brothers unite and formed Gliderak. He defeated the Doomtronics Reptak and Drago use. Finally, they unite into Aeroblitz and defeat Gliderak. In the end, Reptak will go brawling with Dan and Drago until his missing partner was found.
