After returning from the feuding realms of Gundalia and Neathia, Danma Kuusou and his companions continue their lives on Earth. Now, a year later, the virtual reality world of Bakugan Interspace has finally recovered from the alien invasion and has once again become a place for brawlers to gather and challenge themselves. It turns out, however, that whenever Danma's Bakugan, Pyrus Dragonoid, unleashes his might in battle, the Interspace experiences new disruptions. Unable to harness the incredible powers granted to him by Code Eve—the Bakugan Mother spirit—he struggles to maintain control over the Mechtogan contained within him. When it goes out of control, the mysterious mechanical entity wreaks havoc on the battlefield, attacking friends and foes alike. To make matters worse, Bakugan Interspace is at risk of being infiltrated again. An unknown mastermind is sending mutated Chaos Bakugan into the system in order to brainwash brawlers and take control of the virtual realm. In anticipation of the inevitable confrontation, Danma must find a way to keep the Mechtogan's destructive force at bay and rally the Battle Brawlers once again. [Written by MAL Rewrite]

After the final downfall of the rogue Bakugan Naga, peace was brought back to Vestroia. With the help of Danma Kuusou, his companion Pyrus Dragonoid, and other Battle Brawlers, the Infinity and Silent Cores were combined and the realm was recreated. However, New Vestroia will not be given any respite as humanoid alien invaders, the Vestals, arrive and conquer the Bakugan world in one fell swoop. Armed with a fearsome machine capable of restricting Bakugan into their ball forms, they aim to enslave the race as a form of entertainment. Now, the only force standing in their way is the Bakugan Battle Brawlers Resistance—a group of humans, Bakugan, and Vestals who oppose the idea of annihilating a sentient race. Led by Danma, they must venture into enemy-occupied New Vestroia and repel the invaders, to assure the survival of the entire world. [Written by MAL Rewrite]
