Hogan, very easily. Was the guy who made it as huge as it was and the heel turn was one of the most interesting things in wrestling history. Was a different role for him, very different but he pulled it off really well. And like Y2J X said above, it really led to alot of success for WCW. And the promos were always fucking brilliant. After that, you'd probably have to give it to Nash. But I'm sure that point is arguable.
