In the parallel world of Vestroia, a powerful Bakugan in search for power named Naga decides to absorb the energy of the two opposing cores that preserve the balance and peace in Vestroia. However he absorbed too much power and energy found within the Silent Core, the source of negative energy. The Infinity Core, the source of positive energy had been absorbed by Wavern.

They name themselves the Bakugan Battle Brawlers and consist of seven children: Dan, Shun, Runo, Marucho, Julie, Alice, and later Joe. Together they learn more about the origin of the Bakugan, Vestroia, the game involving them, and the battle against people who are under Naga's control.
