#3 Dr Isaac Yankem becomes Kane
Glenn Jacobs didn't come into the WWE as Kane. He was given a string of gimmicks before debuting as The Undertaker's brother, one of which was a dentist!
In 1995, Jacobs was brought in as Jerry Lawler's dentist and went on to feud with Bret Hart. This rivalry led to a match at Summerslam which Yankem lost via disqualification.

There was no way the character of a dentist was going to work in those times, so WWE scrapped it soon. Jacobs was repackaged as Kane and he made his debut at the Badd Blood 1998 PPV, helping Shawn Michaels defeat The Undertaker.
This debut kicked off a decorated career as Kane won World titles, made Royal Rumble records, and appeared in multiple WrestleManias. Kane is currently serving as the Mayor of Knox County and looks ready to kick off a successful career as a politician.
