No doubt. My vote is for Crocodile too. That man beat the living hell out of Luffy...well, for a while anyways.

Won't spoil anyone to the ending though. hehe.
Speaking of Luffy, for a rubber guy, he's one tough dude. Look at all the beatings he's taken and has walked away healthy and fine afterwords.
