#4 Roman Reigns
Before Goldberg shocked the world and defeated The Fiend at WWE Super ShowDown in February, the rumored match for the Universal Championship at WrestleMania 36 was Roman Reigns taking on the sadistic alter ego of Bray Wyatt.
Of course, the plan changed and WWE tried to book a dream match between Goldberg and Reigns in a "Battle of the Spears", but the Big Dog pulled out of the match at the last moment due to concerns over his health.
Whether Roman will return after WrestleMania or not is something to be seen as health would be his primary concern and rightly so. But if he does return, we might be in for the feud which was supposed to take place on the Road to WrestleMania.
Reigns and Wyatt have a huge history against each other, be it as part of The Shield and The Wyatt Family or in singles action. It has been established that The Fiend is here to hurt those who have hurt Bray in the past.
