#2 Isaac Yankem, DDS/Fake Diesel – Kane
The Undertaker character was so great that it helped introduce another WWE legend, Kane, back in 1997. But before becoming the Big Red Machine, Glen Jacobs had a tough time finding the perfect gimmick. Jacobs debuted in the WWE as Mike Unabomb in 1995. He then became the evil dentist Isaac Yankem, DDS.
It was a terrible character that Vince McMahon loved since he made Jacob’s teeth dirty despite being a dentist. When the Isaac Yankem character failed unsurprisingly, Jacobs then became Fake Diesel after Diesel and Razor Ramon jumped ship to WCW in 1996.
As expected, the Fake Diesel persona was unsuccessful and Jacobs underwent another gimmick change. He became Kane, the younger brother of The Undertaker, in 1997. As Kane, Jacobs finally found the perfect character and became one of the greatest and most accomplished big man in WWE history. One of his biggest accolades is become a two-time World Champion. Who would have thought a demon is cooler than a dentist with bad teeth?
