8. The Undertaker
The Undertaker, like Bradshaw, was one of the most physically imposing wrestlers of the Attitude Era. He was also athletic, with great agility, in addition to his strength and power. His love of boxing and mixed martial arts also carried over into a basic understanding of the sports. He actually trained in MMA and is a black belt in brazilian jiu jitsu. He was a passionate UFC fan, and the only reason he didn't enter the sport in the mid nineties was because it couldn't match his WWF salary. He was a tough guy, and a capable fighter. The reputation of his toughness was also what made him so revered in the WWF locker room. Nobody would mess with The Undertaker, and he came to rule the wrestlers.
