#2 Kane
The 'Devils favourite Demon' was introduced into the WWF in 1997 at Badd Blood: In Your House, famously interrupting the first ever Hell in a Cell match between Undertaker (his storyline brother) and Shawn Michaels and hitting his brother with his own Tombstone Piledriver.
Kane would strike fear into everyone he met with his sinister mask, mute persona and huge frame (billed at 7ft tall). Throughout the next 20 years, Kane would win the World championship across WWE/ECW and WCW, multiple tag championships, Intercontinental championship and Money in the Bank winner, as well as having the most Royal Rumble eliminations.

Being able to reinvent himself as different versions of the same character has led to his longevity, but ultimately, Kane the Big Red Machine has been an amazing character throughout the years.
