#2 The Undertaker
The Undertaker is an athlete that never needed a title to measure his success. Still, in WWE, he has been a multiple-time tag team and WWE champion, and deservedly so. The risks that he took over the years, the quality of matches he put on, clearly showed that he was dedicated to the promotion that gave his career purpose.
One of the most interesting things to note about him is that over 27 years earlier, The Undertaker was simply known as ‘Mean' Mark Callous, when he was part of WCW. It was there where he began to earn some notoriety when he teamed up with Sid Vicious, and later Dan Spivey, as one-half of The Skyscrapers. They competed against the likes of The Road Warriors during the different incarnations of this team.

His agility and mobility were something that would become a major calling card for him, and eventually, he left WCW to join WWE. After a nearly twenty-seven year career in WWE, The Undertaker remains one of the most iconic characters and performers in the company's history.
