#1 The Fiend
While The Fiend vs. John Cena at WrestleMania 36 will probably go down as the first time in history that WWE righted a wrong, but it should by no means be the last. In fact, between the magic that the company was able to pull off with The Firefly Funhouse match and The Undertaker needing someone to pass the torch to, why not it be Bray Wyatt?
Again, this is WWE's chance to once again rewrite their own history, give Undertaker fans a very unique career retrospective and even pass the torch to The Fiend as the new face of fear. It goes perfectly with what The Fiend character has become and would be a pretty amazing sendoff for The Undertaker.
The Fiend is obviously this generation's Undertaker and WWE is going to have to acknowledge it at some point. With the chance to flip the script once again in WWE's grasp, why not retire The Undertaker and solidify the future of one of their most popular characters?
