Calling him OP is insane. In fact I I think he's a bit underpowered if anything. If you've beaten him in the campaign I'm sure you can grasp the simple mechanic of not holding hands as a team. His ability literally gets interrupted by melee, so he can't charge it very long and if he is charging it you can just shoot him. His range isn't very spectacular, so it forces him to get in somewhat closes leaving him open to ranged characters. Having played as him he's extremely slow, as slow as Kon. He can be outbursted by pretty much every character, so it's not like he has that going for him. It sounds like you just aren't playing optimally
