1: Vader
Vader was one of the all-time toughest men in wrestling. He was, inarguably, one of the greatest big men to ever grace the squared circle. Vader was known for his size, agility and toughness. How someone as big as Vader pulled off a perfect moonsault is beyond me.
Vader’s matches in Japan were some of the stiffest of his careers. His series with Cactus Jack in WCW is a classic. There was a time when Vader’s eye popped out of its socket while he was wrestling Stan Hansen in AJPW. Vader just popped it right back in and went back to stiffing Hansen.
Although Vader was a genuinely nice man outside the ring, wrestlers were afraid to take on him inside it owing to his reputation as a hard-hitter. Vader would take as much as he would give, but most opponents weren’t in a position to hit back after he was done with them. Even Mick Foley has been on the record saying that wrestlers, including himself, were afraid to step into the ring with Vader at times owing to his stiff shoot-fight style.
