Shawn Michaels
Easily one of the biggest and most prominent names on our list, Shawn Michaels also draws arguably the greatest contrast when comparing his present-day self to that of his youthful, chipper self, who found success in the WWF in the late 1980s and early 1990s as part of The Rockers.
A multi-time tag team champion, Michaels' career accomplishments are probably without equal; he first won the WWE Championship at Wrestlemania XII in 1996, but has a string of Intercontinental, European and Hall of Fame accolades to his name - not least that of The Showstopper for his uncanny ability to, well, stop the show!
Michaels himself happily quips about the fact that he probably looks his age but, in fairness, after a career as eventful as his, it's difficult to expect anything less. A true icon and a legend.
Jimmy Hart
Pound for pound, one would have to argue that the Mouth of the South, Jimmy Hart, is the most legendary manager of all time in professional wrestling, such was his catalogue of clients in WWE, WCW and beyond. In fact, if you look back at some early 1990s WWE action, it's hard to find a heel that wasn't managed by Jimmy, complete with his booming voice and trademark colourful jackets.
His most noted and iconic piece of equipment, though? His trusty megaphone, of course!
