Enel will be VERY hard for any OP character to deal with. He was just unlucky going up against someone who had a distinct advantage over him. Saying that BB isn't exactly a push over either. His devil fruit is a fearsome one, though I still think Enel will take this one. He could just stay in the sky and launch down powerful thunderbolts at BB and he wouldn't really be able to do anything. Plus Enel is more than likely way faster then BB to. So Enel gets this one for me.
