#3. WWE Hall of Famer Kane is also a Grand Slam Champion
In terms of veterans of the business, for years Kane has been a major part of WWE TV. The Big Red Monster underwent multiple variations throughout his career and despite other top names of the business shifting to a part-time schedule, Kane kept himself engaged with WWE television for most of his career.
It was in 1995 when Kane made his WWE debut, but under the name of Mike Unabomb, at a RAW taping. After an intense and slow build-up to his character, WWE finally introduced the monstrous character of Kane at Badd Blood: In Your House in 1997.
From there onwards, Kane pretty much went on a rampage in WWE. Winning nine different championships during his time with the company, Kane established his place as the third-ever Grand Slam Champion in WWE.
Despite only having won a World Title on just two occasions, Kane remains as one of the few superstars in history to have won the WWE Title, the World Heavyweight Title, and the ECW Title. The recently inducted Hall of Famer is a 9-time WWE Tag Team Champion and enjoyed runs with the Intercontinental, United States, Hardcore, and WWE 24/7 Championship, as well.
