It looks like transformations run in the family because Undertaker's brother Kane has also gone through some changes of his own in his WWE career. Kane, however, played not one, not two but four characters in the company. Another interesting note is that he wrestled The Undertaker as all four characters.

He initially competed in WWE in non-televised matches as Mike Unabomb in 1995 and he made his televised debut as Isaac Yankem DDS, Jerry "The King" Lawler's evil private dentist. He was used as an enhancement talent to the stars, losing to top stars such as Bret "The Hitman" Hart, The Undertaker and The Ultimate Warrior.

The following year, WWE legend Jim Ross introduced two imposters, Diesel and Razor Ramon, who were played by Kane and Rick Bognar, respectively. Fake Diesel, as the character became known, was also used as an enhancement talent during his run with WWE. Kane finally caught his big break when WWE repackaged him as The Undertaker's long lost sibling.

Unlike the other previous gimmicks, this one was a success. Kane debuted as 'Taker's brother at WWE Badd Blood: In Your House in 1997 by costing the latter his match against Shawn Michaels.

At WrestleMania 14, Kane and Undertaker had their much anticipated bout which The Deadman won. The Big Red Monster defeated Stone Cold at WWE King of the Ring 1998 in his first PPV main event to win the WWE Championship. He went on to win two more World Titles during his career.

Kane also holds several records in WWE. He has competed in the most PPV matches in WWE, eliminated a total of 44 competitors in the Royal Rumble and he held the record for most eliminations in a single Rumble match from 2001 to 2013.
