The Brawlers have finally made it to Vestroia where they hope to confront Naga and retrieve the Silent Core to save the universe. But when they get there, they realize that Naga is nowhere to be found. It turns out that he's headed for Earth, where all of his henchmen Bakugan have started popping up and attacking. The world is in a complete state of chaos and the evil Bakugan attempt to seek out Wavern, who holds the Infinity Core. This is the final piece that Naga needs to become supreme ruler. Suddenly, an urgent transmission is heard over Dan's Bakugan. It's from Joe, who explains the situation on Earth. Joe begs his fellow Brawlers to return to Earth to battle Naga's evil Bakugan. But how can they return to their home, and is there enough time? Suddenly, Wavern and the light from the Infinity Core appears in Vestroia ready to guide the Brawlers home.
