5 feuds Roman Reigns can have as Universal Champion 

#2 Braun Strowman

He's not finished with you!

I was too doubtful when I chose Braun here but I just can't imagine a better rival for Roman Reigns than the "Monster among men". We have seen everything there has to be seen in this rivalry. Right from Ambulance matches to steel cage matches. Give them any stipulation they will tear the house down.

This feud makes a lot of sense and is realistic to happen as the WWE universe wants to see Braun as the champion. So get ready for some more destruction.
