Number one is Royce Gracie. He was the guy who beat everybody in the open weight class. Number two is Chuck Liddell. He was the face of the UFC for a very long time. Number three is Georges St-Pierre. And number four is Khabib Nurmagomedov, because he's the only guy in the sport who left undefeated.
