He helped Dan and Drago fight Centorrior and Druman but was later defeated and then fell into lava. He survived as he is a Pyrus Bakugan but he was then killed in a later battle against Centorrior and Druman. When he first rescued Dan and Drago, he took them to his home in a cave at the base of a large cliff. There, Drago figures out that this is not just an ordinary Bakugan who has saved them but as Nova Lion later confirms with a chuckle, that he is one of the oldest Bakugan in existence. Unfortunately they would later battle Centorrior and Druman and Nova Lion would die defending Drago who he foresaw to be the next great leader of Vestroia and more: the Perfect Core of Vestroia. He also told him about how Naga and Wavern came to be and how the new Bakugan were created.
He is the only Bakugan to have a different attribute from the first version seen to talk.
It's possible he knew the Original Dragonoid and Dharaknoid due to him being the oldest Bakugan in Vestroia and witnessing New Vestroia split into six different worlds which happened when Dragonoid and Dharaknoid where created.
The spikes on his back are facing the opposite direction of Tigrerra's.
