#1 The Undertaker
Undertaker's contribution to the world of professional wrestling is too difficult to put into words, and that is why he will forever remain the greatest performer of all time.
The Phenom carried a supernatural character back in the day and made it the most compelling dispositions this business will ever see.

His dark inception during WWF garnered tremendous attention from the crowd, and disturbed a lot of casual viewers for his horrifying and spot-on enactment of a Dead Man.
His time during the Ministry of Darkness catapulted his stature to the top of professional wrestling and exposed his evil side in a way that made him so dangerous than the rest of his peers.
His feuds with Mankind, Randy Orton, Shawn Michaels, Stone Cold, Triple H, Kane, and Bray Wyatt unleashed his inner darkness, and took his opponents to hell.
While he might retire and hang up his boots in some years, there's no denying that the Undertaker will go down in history as the darkest and compelling character of all time.
