Bakugan

In the Vestroian star system, six planets are home to different species of Bakugan, locked in a perpetual struggle. When experimental weaponry malfunctions, the Bakugan are transported to Earth, where they crash-land as Baku-Balls. As these balls unfold, humans encounter towering 10-foot-tall Bakugan for the first time, and despite their differences, form a bond with the creatures, embracing their culture and traditions. This newfound friendship allows children to tap into their inner strength, gaining massive, Kaiju-like abilities.
