#1 Killian Dain
Anybody who's seen Killian Dain work in NXT, knows that he's a special athlete. Not only is he incredibly gifted and a physical specimen, he can also move with the speed of a gazelle. SAnitY should be due for a call-up, almost any time now. Dain vs. Lesnar could be a dream match.
If you haven't watched Dain in action, do check out just how destructive he was at the WarGames match that NXT just put together. Imagine the kind of destruction he could carry out in the main roster. In fact, Dain could also have great matches with Strowman and Joe, going forward.
With Killian Dain, we conclude our list of 5 potential opponents for Brock Lesnar, following WrestleMania 34. This is provided that Brock Lesnar does not head to the world of MMA, of course.
