^Your point notwithstanding (it is a good line of thought, even if I do not necessarily agree with it), Crocodile is an even worse match-up than Luffy. Crocodile's weakness is liquids; Magellan's attacks are liquids. So, Crocodile vs. Magellan = Magellan's victory. Jinbei, being a fishman (who ever heard of liquid hurting a fish?
), might be a better match-up.
