5 "undead" fighters that are UFC's version of The Undertaker

#3 Roy Nelson

Nelson never backs down from a challenge

If you haven't loved Big Country at one point or another during his UFC tenure, then you may not be human. The guy is one of the most entertaining fighters in recent times, simply due to his phenomenal knockout power combined with his bizarre physique that continues to baffle fans to this day. After all, you don't see too many top fighters in that kind of shape.

But that's never bothered Roy because the important thing to remember is his chin. Over the course of his career only Andrei Arlovski and Mark Hunt have been able to knock him out and when you consider some of the contenders he's faced, that's a pretty impressive record. You may not like his style or attitude, but Nelson should forever be known as a bad ass in the heavyweight division.

Onto a man who has recently returned after a few years away.
