When mysterious portals begin opening across Earth, strange creatures known as Bakugan emerge from a distant dimension called Vestroia. What starts as a worldwide game quickly becomes a battle for the fate of two worlds. Teenager Dan Kuso and his friends—Runo, Marucho, Julie, Shun, and Alice—discover that their Bakugan partners are real, living warriors. As the bond between Brawler and Bakugan grows stronger, the team uncovers a dark conspiracy led by the masked and ruthless Masquerade. Armed with the terrifying power of Hydranoid, Masquerade seeks to dominate both Earth and Vestroia by harnessing the energy of the Doom Dimension. With cities falling into chaos and powerful Bakugan disappearing into the darkness, the Battle Brawlers must unite allies from around the world—including Klaus, Billy, Komba, Julio, Chan Lee, Akira, and Shuji—for the greatest brawl in history. As Drago and Hydranoid race toward an inevitable showdown, Dan must learn what it truly means to be a leader. The fate of two worlds will be decided by one final battle.
