17 WWE Returns Confirmed For Raw 25th Anniversary Show
16. Ric Flair
'The Nature Boy' said his first farewell to WWE in 1993 following a scintillating retirement match with Mr Perfect on only the third ever episode of the flagship show, but his real last goodbye dominated an emotionally charged post-WrestleMania Raw in 2008 following his 2001 return to Vince McMahon's employ.
Things looked bleak health-wise for Flair in 2017, but a brief appearance on SmackDown Live alongside daughter Charlotte at the tail-end of the year was an thoroughly pleasing return to form for one of the greatest of all time. He'll presumably be in similarly fine fettle in whichever arena gets the good fortune of his presence.
