This is Hades, a mechanical Bakugan from Bakugan Battle Brawlers: New Vestroia. It is the mechanical counterpart of Alpha Hydranoid, who's data and genetic code was used to create it, and it was made to look like him and pose as him, until the synthetic skin was destroyed in battle, revealing his robotic interior. It was the guardian bakugan of Shadow Prove, until Alpha Hydranoid destroyed it in battle, and was replaced by darkus MAC Spider.
