#5 Kane
The Big Red Machine but Kane had a very different character which was nothing short of mind-boggling before the WWE decided that he needed a complete overhaul. Before he became the monster we know today, Kane shockingly played an Isaac Yankem dental gimmick as can be seen in the picture above.
As many wrestling fans would expect, his was not a very popular or a successful character and the WWE soon looked to use Kane in a different way. He would then go on to play a poor copy of Kevin Nash which was yet another poor use of the superstar.
It would prove to be third time lucky when the WWE decided to give the man a role which he could really thrive in. That role would be the role of The Undertaker's brother.
Kane has seen massive popularity and success in this character and remains one of the most feared superstars to ever walk into a WWE ring.
