#1 Goldberg (to "The Fiend" Bray Wyatt)
For a considerable period of time, it seemed likely that "The Fiend" Bray Wyatt would defend his WWE Universal Championship against Roman Reigns at Wrestlemania 36. Reigns had yet to win a championship since beating leukemia and had yet to square off against Wyatt in his newest incarnation.
Enter Goldberg. The 53-year-old WWE Hall of Famer was booked to challenge Wyatt for his title at this past February's Super ShowDown event in Riyadh, Saudi Arabia. WWE is well-known for bringing in big-name Superstars for its Saudi Arabia shows and Goldberg - a multiple-time World Champion - definitely fits that bill.
It was rumored that the original plan for the Goldberg Vs. Wyatt match was for "The Fiend" to take the victory, setting him up for his WrestleMania clash with Reigns. However, Goldberg was reportedly not on board with this plan and insisted that he wanted to beat Wyatt.
The WCW icon has a considerable amount of creative control over the appearances that he makes with WWE and seemingly refused to lose to Wyatt's dark and ominous character because he believed it would damage his standing with kids who view him as "a superhero".
Goldberg allegedly pushed the issue and was given the win and the WWE Universal Championship, forcing the WWE to make the first of what would turn out to be many changes to their WrestleMania 36 plans. Goldberg eventually lost the title to Braun Strowman in quick fashion at the show.
