#1 Roman Reigns and Jason Momoa
Roman Reigns and Jason Momoa have a lot in common, and that isn't just their physical appearance or face but beyond that. Jason Momoa played the title role in 'Aquaman' and if they ever try to step inside the ring together or become a part of any storyline whether inside the ring or on a film set, the results will be awesome.
They do have the same body type and face, and their alliance will benefit both the company and the performer. Roman Reigns is currently a top heel in the company and wreaking havoc on SmackDown. But if he ever steps back in time, a feud between them would be a great idea. A Superman versus an Aquaman is definitely a good story worth telling, and if all the parties agree to present it on WWE programming, then neither of them should hesitate from making an appearance.
With Reign's cousin The Rock's Hollywood connections, it would be interesting to see if a match between these stalwarts is a possibility.
