Bakugan Battle Brawlers - S04

After returning from the feuding realms of Gundalia and Neathia, Danma Kuusou and his companions go back to their lives on Earth. A year later, the virtual reality world of Bakugan Interspace has finally recovered from the alien invasion and is once again a place where brawlers gather to challenge themselves. It turns out, though, that whenever Danma's Bakugan, Pyrus Dragonoid, unleashes his power in battle, the Interspace suffers new disruptions. Unable to control the incredible powers given to him by Code Eve, the Bakugan Mother spirit, he struggles to keep the Mechtogan inside him in check. When it goes out of control, the mysterious mechanical being causes chaos 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 to brainwash brawlers and take control of the virtual realm. As the inevitable confrontation approaches, Danma must find a way to hold back the Mechtogan's destructive force and rally the Battle Brawlers once more.
