Kane

When Kane saw Dan being kidnapped, he thought he had to do something. He tried to form a group of brawlers capable of fighting the gundalians. Just before he would launch an assault, he had been traced down by Dan, who was now the emperors assasin. After a long battle he won from Gundalian Drago, but before he was able to rescue Dan, Dan was teleported back to gundalia.

Kane was sure that if he would go to Gundalia, he could rescue Dan. When he arrived at Gundalia, Dan was already waiting for him together with the new Drago. Kane wasn't able to cope with this kind of strength and was defeated by Dan.

Kane was put in a capsule of Kazarina's machine and transformed in a gundalian. He now is the servant of Dan, helping him to destroy his former allies. He also got a new bakugan from Kazarina: Darkus Oblivion.

When Ren fights Marucho, Kane is there to help the emperor if something goes wrong. When Marucho calls in the resitance, Kane wants to help his emperor and join the brawl, but Ren tells him to stay put. Ren beats all of them and tells Kane to use Doom Portal on his former friends.
