In Bakugan Interspace, there is a Capture the Flag competition in the Dungeon arena. Marucho tries to convince Paige and Rafe to try to not battle as much in the competition, but they take that as an insult and they leave angrily. Soon, Shun comes and tells Marucho that the only way to stop the chaos is to battle.
Elsewhere, Sellon is seen contacting Mag Mel and informing him about the Capture the Flag challenge and he thinks that the Chaos Energy produced will be massive and he will be able to break out of his prison.
At the beginning of the competition, a brawler enters but is quickly defeated by a large group of brawlers. Then, Shun arrives with Taylean and defeats them. Meanwhile, Rafe and Paige are doing well until Ben comes with Horridian. Rafe and Ben use their BakuNano and attack each other. Paige joins in but then a beam from Hyper Pulsor comes and attacks them. Jack and Robin arrive but Marucho jumps in with Tristar and disappears in a giant wave with Paige and Robin.
Meanwhile, Dylan begins to wonder who will win since the participants are strong.
Down in the sewers, Rafe and Paige complain that they didn't need Marucho's help. He tries to explain them that pure strength will not always lead to success. The two disagree but then they are ambushed by Jack. They begin to run but Marucho faints. Tristar explains that Marucho tried to plan the safest route with the least battles for 2 days and that tired him out, much to Rafe and Paige surprise, who underestimate Marucho's skills. Then, when they get closer to the flag, Ben and Robin are there. Jack then comes from behind and they all attack Tristar at once. However, Marucho uses an ability which acts as if Tristar wasn't there which leads the attacks to each other and Team Anubias loses. Also, Shun wins his battle against Soon and Chris.
Marucho arrives at the temple, where the flag is at the top. There, Marucho sees Sellon who uses her BakuNano. Using her BakuNano, she manages to defeat Tristar but only before she finds out it was a distraction. Rafe with Wolfurio and Paige with Boulderon come out. As Boulderon runs up the temple, Sellon unleashes her Mechtogan, Braxion. Rafe succeeds in stalling for time as Paige gets the flag and the win goes to the Battle Brawlers. Then Marucho reveals his plan: He knew Shun would attract many Brawlers so there would be less people to brawl. Also, going through the sewers would reduce the amount of brawlers too and distracting Sellon was useful as the main objective was only to get the flag. After, Rafe goes on his knees and apologizes for underestimating him and being rude to the Brawlers and wants Marucho to give him another chance to be his student. Then he convinces Paige to do the same and she, unwillingly agrees and the 3 brawlers unite. Shun watches them, and comments that Marucho's plan was right all the time.
Back in New Vestroia, Dan, Drago and Wavern see a rainbow light in the cave and they see Mag Mel and Razenoid telling them to battle more to give him more energy. They are teleported out of the cave and a mysterious yellow mark appears on Dan's hand and Drago's chest. They find out that the masked entity is called Mag Mel and the Bakugan with him is called Razenoid. Wavern says that the names are familiar but Dan knows what the light is- Code Eve.
Where Mag Mel is locked up, he says he's glad that Dan remembers the source of the connection. Then, he says that Dan will eventually learn the power of their connection.
