#2 Brock Lesnar

WWE needs to keep Bray Wyatt's new character safe for as long as possible, and if Wyatt is to take a loss in a match, it shouldn't happen unless the time & opponent are right. Until then, WWE should not even think about Wyatt taking a loss.
Brock Lesnar was the one to convince Vince McMahon to have Goldberg squash him at Survivor Series 2016, so he won't have any problems putting over Bray Wyatt. However, the problem is that we can't expect a Superstar to go over the Beast Incarnate without putting him over at some point during the feud.
While the Fiend wouldn't lose much momentum by taking a loss against Lesnar but if WWE makes a mistake in the way they book the loss, it could cost them the entire effort they put into reinventing Bray Wyatt.
