Drago returns to Earth with a new ally named Mira. The five original Bakugan that helped restore order to New Vestroia have been captured, Drago is now being targeted, and a group of humans known as the Vexos are taking over New Vestroia. With the help of Dan and the Battle Brawlers though, Drago believes he will have enough power to not only free New Vestroia but his friends as well.
