10 WWE Superstars you never knew once played very different characters

#7 Kane and Isaac Yankem

The Big Red Machine was once a very dirty dentist...

With the exceptions of The Undertaker and Triple H, there is no WWE Superstar with greater longevity than the man known to most fans as Kane.

The Big Red Machine is for all intents and purposes retired, as the man who plays him, Glenn Jacobs, has embarked on a successful political career. Nonetheless, Kane is a former multi-time champion in WWE, holding the company's top prize on more than one occasion as well as holding the Intercontinental Championship and enjoying many Tag Championship runs. Kane is one of the most dominant forces ever seen in the company. At seven feet tall and over 300 pounds, the monstrous figure battled pretty much all the major names WWE has had to offer between 1997, when the Kane character debuted, and 2016, when his appearances became more sporadic.

You may not be aware of it, but before his career-defining success as The Undertaker's half-brother, Glenn Jacobs portrayed a man called Isaac Yankem. The man with the punny name arrived in 1995 as the evil dentist enlisted by Jerry "The King" Lawler to help him thwart his rival, Bret Hart. Yankem may have cared for the teeth of his patients as a day job, but his own dental hygiene left an awful lot to be desired!

Yes, The Mayor of Knox County, Tennessee certainly went through quite the transformation.
