Watch Bakugan: Battle Planet Online

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]

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]

Bakugan Interspace is a virtual reality system, where players can brawl against each other and take part in tournaments. Initially designed to help practice and enhance Bakugan skills, it quickly became a meeting place for many enthusiasts. During one of Danma Kuusou's duels, the Interspace crashes, and he gets knocked out cold. Before regaining consciousness, he experiences a vision of Bakugan at war with each other once again. The explosion of energy that accompanied Danma's fight and caused the shutdown of the system sends shock waves across the galaxy, attracting the attention of the Twelve Orders, a Gundalian organization. They infiltrate Bakugan Interspace, looking for strong brawlers to join them in their upcoming war with another alien race, the Neathians. Danma and his companions—Shun Kazami and Chouji Marukura—soon find themselves caught up in an extraterrestrial war. However, distant as it may seem, the conflict threatens the very sovereignty of Earth and the future of the Bakugan race as well. [Written by MAL Rewrite]
