Peace returned to Vestroia when the villainous Bakugan Naga was finally vanquished. The Infinity and Silence Cores were joined, and the world was reconstructed with the aid of Danma Kuusou, his ally Pyrus Dragonoid, and other Battle Brawlers. Nevertheless, there won't be any solace for New Vestroia when humanoid extraterrestrial invaders known as the Vestals show up and swiftly take over the Bakugan universe. They intend to enslave the race as a sort of entertainment, armed with a terrifying contraption that can confine Bakugan to their ball forms. The Bakugan Battle Brawlers Resistance, a coalition of humans, Bakugan, and Vestals opposed to the eradication of a sentient species, is now the only thing standing in their path. They must set forth, guided by Danma to ensure the survival of the entire globe, enter enemy-occupied New Vestroia and drive back the invaders.
