3. The Undertaker
No one has ever paralyzed the audience with immense fear as The Undertaker has. When The Phenom stands across the ring from his opponent, you could see Taker's opponent tremble and shudder in fear. Taker has long been considered as one of WWE's best stars and he is a definite future Hall of Famer, but his character is one of WWE's greatest creations.
Many like The Boogeyman, Kane, Papa Shango and Mankind have terrified fans across the globe, but none have had the terrifying the impact upon the audience like the Deadman has. However, Taker has finally found some competition in the form of The Fiend, who has instantly cast his dark shadow over the WWE Universe in a horrifying way.
According to recent reports, WWE is concerned The Fiend persona is "too scary" for the younger audience. That is how frightening and dreadful Wyatt has been as The Fiend. Wyatt and Taker have crossed paths before, and Taker emerged victorious in their one-on-one encounter at WrestleMania 31. Given their history together, there's no love lost between these two.
The Fiend versus The Phenom is a blockbuster dream match that would arouse great interest from fans. Taker could put over Wyatt, who could then take over Taker's yard as the Reaper.
