The Bakugan Battle Brawlers enter Vestroia and realize Vestroia has become a hybrid world where two elements are mixed together to make one element together. They enter the Ventus and Aquos world where they meet Tayghen and Hairadee: two Bakugan of both Ventus and Aquos elements. As they fight, they suddenly see the portal to the next hybrid world of Vestroia is closing and so they agree that Shun and Marucho are to stay in the Ventus and Aquos world to defeat the two Bakugan. The rest of the Bakugan team disappear through the portal into another dimension of Vestroia.
