Hard to say, but i would lean toward Ogun. Even when he posessed and used Kitty Pryde's human form, he was still able to hurt Colossus with just strikes and skill. Anyone who's physically above that would present an even greater threat to Batman. The demonic telepathy-like stuff and the mystical stuff may present some issue for Bats as well. If "bloodlust" means he will use all his powers, Bats may have a tough time.
