#3 "The Fiend" Bray Wyatt (May win)

After his crushing defeat to Goldberg at Super ShowDown, it might not be such a great idea for Bray Wyatt to return to the Universal Title scene. But since then, the wrestling world has been turned upside down. Roman Reigns had to pull out of WrestleMania, meaning Braun Strowman faced Goldberg instead.
And now that Strowman is the Champion and Reigns might not return to WWE until this situation completely goes away, The Fiend might reclaim the big blue belt. The seeds have already been planted for the feud between Wyatt and Strowman.
The two of them are extremely close friends, so hopes will be high that they will be able to have one hell of a feud. But in the end, it is likely that The Fiend will stand tall.
It would be part of the rebuilding process, a continuation from Bray Wyatt's huge WrestleMania victory over John Cena, in one of the most creative "matches" in WWE history. The Firefly Fun House will probably be the home to the Universal Championship once again.
