#1 Former WWE Superstar Kane
The Big Red Machine Kane is one of WWE's biggest stars, and throughout his career, he has faced many big names and held many titles. However, at the beginning of his WWE career, The Undertaker's half-brother wasn't in a good place. He was also cursed with horrible gimmicks, but managed to overcome them and became a high-profile name in the wrestling industry.
In 1995, he played a heel dentist named Isaac Yankem DDS, an enhancement talent who put other stars over.
In 1996, after Kevin Nash and Scott Hall left WWE for WCW, Isaac Yankem was repackaged as Diesel. As Fake Diesel, Kane failed to replicate Kevin Nash's success, and he continued to be used as a stepping stone for other stars.
At that point, Kane's WWE future was uncertain, but luckily for the former, there was an open spot for the Kane character, which he got to play and found success as in a career that spanned over two decades.
The former World Champion is undoubtedly a shoo-in for the WWE Hall of Fame.
