#1 The Undertaker
The most surprising one on this list is The Undertaker. The Deadman played a key part in helping WWE's growth into a global phenomenon and also has stayed loyal to the company for three decades.
The Phenom was signed by WWE. Vince McMahon, though, was in two minds to sign The Undertaker in 1990, who was then a part of WCW. McMahon had watched Undertaker - who was then known as 'Mean' Mark Callous - in a match against Lex Lugar but was not impressed.

He felt that the future Undertaker resembled a basketball player. Bruce Prichard revealed that Vince McMahon did not want to meet The Undertaker:
"Mark had a dislocated hip, but worked the match anyway because he knew that he was going to be meeting with Vince the next day. It wasn't the best match in the world and Vince didn't want to meet with him. We finally got the two together, and, as you know Mark, man, he's magnetic in and of himself and he convinced Vince that, 'hey, I'm your guy' and he took off from there."
