Bakugan: Battle Planet

A group of preteens known as the "Awesome Ones" make videos on the website ViewTube. They stumble across a race of battling biomechanical creatures called Bakugan. They soon befriend the Bakugan and begin to battle each other with them, all while defending their neighborhood from thugs who use the Bakugan for malicious purposes. They encounter many foes such as Philomena Dusk and the mysterious Magnus, bent on beating their champion in a Bakugan Battle to be the best brawler. (wikipedia)
