#4 Did: Shawn Michaels
Arguably one of the best to ever set foot in a WWE ring, Shawn Michaels would have been classified differently on this list as his career was seemingly cut short in 1997. He suffered a career-threatening back injury while wrestling The Undertaker at the Royal Rumble.
Following his unexpected retirement, HBK focused getting rid of his personal demons and briefly operated his own wrestling school where he had a hand in training future stars such as Daniel Bryan and Brian Kendrick.

Despite the odds, HBK returned to the WWE in 2002 and had some instant classic with Triple H.
Thus, began a career renaissance for the WWE legend that saw him wrestle classic matches with the likes of Chris Jericho, John Cena and Kurt Angle among many others.
His return would last until 2010 following a typically show stealing performance against arguably his greatest opponent, The Undertaker, at WrestleMania 26.
HBK would wrestle again for the WWE at the 2018 Crown Jewel event before retiring once more.
