The battle begins when the story of how the game of bakugan was created with the help of Dan Kuso and many other children, and how it quickly became popular around the world. Dan faces Akira's older brother as Drago and a mysterious white dragon fight in Vestroia, with the dragon destroying itself by getting to close to the core of Vestroia. Dan quickly beats his opponent, but in a rematch, things are far more heated. Drago and a Darkus Bakugan fight it out, with Dan watching them. Their fight gets interrupted as Drago's fight gets in the way, and Dan then gets Drago in the fight and gives him his name.
