Wiseman Cometh is the 28th episode of Bakugan: Mechtanium Surge. It aired on September 17, 2011.
The episode begins right after the battle between the Battle Brawlers and the Mechtogan. The Battle Brawlers start looking for Gunz but then run into Reptak, who is also looking for Gunz. After that, they go to the Bakugan Research Center in Bakugan City where Reptak explains his story to the Battle Brawlers. Jaakor, Radizen and Roxtor don't believe him, but then Mira says that it is a little unrealistic. Some time later, Mira shows Dan the data she was able to retrieve from his Bakumeter about the strange Mechtogan and Dragonoid Destroyer. The Brawlers then discover that Dragonoid Destroyer has two spaces on his shoulders to launch Bakugan during a battle.
Meanwhile, in the Doom Dimension, the Nonet Bakugan wonder if Coredegon and the Mechtogan were victorious against the Bakugan, and they decide to ask Worton, but he tells them to be patient. Then a human calling himself Wiseman appears to them, telling about Drago as the descendant of the Original Dragonoid for banished them in the Doom Dimension and offers them their freedom in exchange for their help in summoning the four Mechtogan that attacked Bakugan City earlier. Then they head down to Bakugan City and immediately start wreaking havoc on the construction site. Julie would report what was going on at the construction site and told Dan to get down there with the other brawlers. When the Brawlers appear to battle, they got hammered by the Nonet Bakugan and Mechtogan until they summoned Dragonoid Destroyer and were about to unleash a jumping attack with Jaakor and Radizen until Mira told them that since Radizen is not a Baku-Sky Raider, he cannot be used in a jumping attack and then found out that Reptak could be used because he is a Baku-Sky Raider. So, Dan and Drago summoned Dragonoid Destroyer and then attached Reptak and Jaakor to Dragonoid Destroyer and they launched the jumping attack. Then Mira creates an Aquos Blasterate for Radizen and he and Marucho join the battle and easily repel the Nonet Bakugan and the Mechtogan. Wiseman, defeated, leaves the scene. Dan tries to go after him, but he disappears. The Brawlers wonder who he was, but Reptak says that the way that he launches Bakugan was similar to his missing partner Gunz.
