He managed to defeat them, despite not using any BakuNano himself. Finally, they are at the point where they are given the powers. They are all quickly defeated by Titanium Dragonoid's Dragon Force Striker and Sellon said that was incredible. The episode begins, with Dan battling two Subterra and Darkus brawlers in Interspace with Marucho and Shun observing the battle. Both sides are pushing themselves to the limit, but Wiseman and the Nonets summon the evil Mechtogan to help them destroy their enemy. Meanwhile, Marucho decides to have a battle to make up for Dan having to sit out, so he fights against Jack of Team Aubias. Anubias then tries to destroy Dan and Sellon tells him that their trying to retrieve the Key not blowing it away.
After the battle, the Brawlers observe two rival teams battling, Team Anubias and Team Sellon. Back at the base in Gundalia, the battle brawlers find out that the Chaos Bakugan are all heading to the city area, where there are Gundalians defending the area such as Mason and Jesse from Gundalian Invaders. The Brawlers mourn their loss and they look outside, as many people think they see a dark moon, the Brawlers really know that it is Mag Mel, who he has actually absorbed the energy from the deletion program and the catharsis was completed, revealing an Evolved Razenoid. Then, Drago's long-lost beloved girlfriend Wavern appears as a as her true physical self had perished long ago and congratulates them. The Mechtogan overwhelm the others so Dan and Drago share their powers with the others and to make them summon their own Mechtogan: Silent Strike for Taylean Shun , Vexfist for Boulderon Paige , Accelerak for Trister Marucho and Swift Sweep for Wolfurio Rafe. To make matters worse, Zenthon reappears and everyone learns that Drago created him. They are then attacked by a Flash Ingram, but are saved by Noah and his Subterra Ziperator.
Rafe is suggesting that he should follow Dan, but Dan rejects the idea. After they are done, Shun leaves, while Jaakor stays to meditate. Anubias then fuses the two into Mutant Krakenoid and Mutant Krowl. Sellon is shown to be fascinated by Helios's power but not to the point of desire. Dan and Drago then wonder what they just did. Anubias and Sellon then decide to battle Zenthon and send out Horridian and Spyron.
Once he broke free from the vines, he went to find a way to escape from Wiseman's base. They are teleported out of the cave and a mysterious yellow mark appears on Dan's hand and Drago's chest. Marucho then arrives, and tries to tell Shun that he is battling way too much and suggests a break on Earth. On arrival, they see Bakugan Interspace in ruins, then find Team Anubias running from a Darkus Cyclone Percival. Wavern suggests looking through their memories.
Chris is surprised to see that he has become more confident, and although Soon says that they don't want his help, calling him a cowardly crybaby, Noah continues helping them. Dan later leaves after Marucho yelled at him and Shun also leaves talking to Taylean about Dan and he bangs a wall. Then they, alongside Team Anubias, continue to try to move the Chaos Bakugan to Section B of Bakugan Interspace. Shun however, refuses their help and leaves while Marucho's father asks him to quit the Brawlers, surprising Marucho. Shun, however brushes him off and declares that as the new leader of the Brawlers, its up to him to get the Brawlers back on top. Marucho is right and someone appears in the Dimension Portal.
Betadron, hesitant at first, agrees and takes Gunz with him. Ren then brings them to a secret hideout. Outside the base, the two girls are attacked again, with Soon wanting to be killed, but the Brawlers step in and fight. Drago's Revolutional attack then goes up against Zenthon's lasers but Zenthon is unable to take it but Anubias's Iron Dragonoid and Venexus continue to attack Titanium Dragonoid. Prime Minister Nurzak and Queen Fabia then leave. That night, in Dan's house which is located in Bayview, he sees a vision of Gundalian Soldiers trying to hold off the Chaos Bakugan. Drago lays waste to the battlefield and he summons Mechtogan Zenthon.
So Chris from Sellon's team battles alongside her, making it a tag-team battle. Marucho arrives at the temple, where the flag is at the top. After they fight, the result of an explosion leads to Dan losing. Marucho then plans to fire up the erase sequence but Taylean and Shun notices that Team Anubias are still there and he tells Marucho and the others. Shun arrives on the scene and battles the two brothers.
Jack then comes from behind and they all attack Tristar at once. However, the residual energy created from them caused an outburst of energy which not only destroys them but Razenoid absorbs it to become bigger and stronger. With his addition, they are defeating many of the Dreadeon clones. He advances to the semi-finals to battle Anubias. They then attack them but Rafe and Paige come and summon Vexfist and Swift Sweep. As Boulderon runs up the temple, Sellon unleashes her Mechtogan, Braxion.
