#1 The Undertaker - 'Mean' Mark Callous

The Undertaker is arguably Vince McMahon's greatest creation of all time. For three decades he has been a pillar of the company and to this day remains one of the most popular wrestlers in the world. Mark Calaway has played the role of a Deadman better than anyone could have ever expected and deserves all the fame and respect that he has earned over the years.
It is hard to think of Calaway as anything other than The Undertaker. But surprisingly, Calaway had been struggling to make it in the wrestling industry for more than half a decade before becoming The Undertaker.
One of his early wrestling names was 'Mean' Mark Callous back when he was in WCW. He was booked as a morbid character who had a fondness for pet snakes and Ozzy Osbourne. Just try and imagine The Undertaker listening to Ozzy Osbourne's heavy metal songs. It is impossible!
Let's just say 'Mean' Mark Callous would have never had a 21-match winning streak at Wrestlemania.
