Although a rating failure in Japan, it was a success in North America. In North America, it is licensed by Nelvana, and aired on Cartoon Network in the US, and Teletoon in Canada. The series was popular enough to spawn two sequel series, Bakugan Battle Brawlers: New Vestroia and Bakugan Battle Brawlers: Gundalian Invaders. Plot In the world of Vestroia, a powerful Bakugan in search for power (a small marble magnetic sphere which when thrown on a gate card turns into a highly strong warrior) named Naga decides to absorb the energy of the two cores that preserve the 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. In the first series, the story centers on six friends who find metallic cards which have fallen from the sky. They name themselves the Bakugan Battle Brawlers and are made up of seven children: Dan, Shun, Runo, Marucho, Julie, Alice, and later Joe.
