Mind Search.The episode starts at a cave in New Vestroia, with Wavern telling Dan and Drago that the mystery to the entity in their nightmares will be solved in the cave. Then, Dan and Drago enter the cave. 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. Before the competition, Team Anubias meet up. Anubias gives Bolcanon to Robin, Krakenoid to Jack and Horridian to Ben. Anubias then states that he will not be participating in the competition. 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 disappear in a giant wave with Paige and Rafe. Meanwhile, Dylan begins to wonder who will win since the participants are strong and even in terms of strength. Then, Shun arrives in another location and is attacked by Soon and Chris. They begin to insult Shun (Chris calls him an "emo twerp") and they use their Bakugan and BakuNano to battle Shun. 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...
