1. Rampage Jackson. Fucker is the scariest man I have ever seen. He can't even communicate properly, but he just beats on people with no mercy. http://www.youtube.com/watch?v=WsBWAdpdUVA
2. Bob Sapp: Thats right, 6'4'' 350 pounds. Beat the shit out a 6'2'' 250 lb beast then called out Mike Tyson who was watching the fight. Wanted to take on Tyson right there.

3. Fedor Emelianenko: Top rated MMA fighter in the world. Crazy thing about him is he doesn't even look like a fighter. He has no problem breaking bones in the ring, and is virtually indestructable.
