I think Law would win..

I think so

omg i hav no idea

robin would snap his back

Kenacon; she could snap his back, but we don't yet know exactly how his power works. He may be able to slice those hands off without it hurting her.

Robin's pretty strong but law is luffy's rival,
he's gotta be captin strong!!! x]

I can't help but think that Law would win - he is pretty powerful. XD. Plus, Robin isn't really that strong, she just has an annoying power, one that could easily be neutralised by someone strong like Law... Plus, he is a swordsman, I'm sure he could cut the hands off of him.

Admittedly, her power would make this pretty interesting, since she could regrow her whole body in any given location and his sword strikes don't actually cause any physical harm, but he does have complete control of the space around him. I don't see Robin penetrating that in any meaningful way.

Honestly I closed my eyes and flung my mouse clicking xD. apprently I choose Robin I agree with flame her ability would be hard to get by. and Law maybe strong and have a sword but we've see Robin Disarm "Strong" people with swords on more than one occasion.

hard choice but law has haki

No contest at all.
