Re: who would win these fights (one piece)
1. Luffy. Last time I picked Kuma, but I don't think we've seen the extent of current Luffy's powers yet.
2. Doflamingo... I guess.. Difficult choice
4. Crocodile. Moriah is weak. He relies on other people's strength(his zombies), not his own. Him by himself isn't that hard to deal with.
5. Doflamingo. At this time, BB can't even dodge attacks, and he talks too much
6. Vista. Not far lack of trying, but right now, Vista takes him mid diff
7. Tie... I honestly don't know. I'm leaning towards Jinbe, since he can hurt him even when in diamond shape.
