One day, cards start falling from the sky, and the children who collect them create a game called Bakugan. However, this is not just a game: the fate of the universe of Vestroia, where the Bakugans live, depends on Bakugan. To save Vestroia, the Infinity Core must be found to restore balance in Vestroia, but there are three obstacles in the way of six friends who call themselves Bakugan Warriors and are trying to find the core: Naga, Hal-G, and Masquerade.
