Well, arguably Enel is the most destructive character in One Piece thus far. Not everyone can atomize islands or send 200m volts of thunder bolts. So the question is, can anyone other than Luffy the rubberman stand up to him?
Obviously Blackbeard comes to mind, who is able to neutralize devil fruit powers and possesses the power of darkness itself. Yet he's not immune to lightning.
So who would be able to win a battle between God Enel and Marshal D. Teach: A.K.A. Blackbeard?
