#4 Terminator Roman

This entry is really quite simple, even though it may not seem like it. Roman Reigns was always at his best when he was a member of The Shield, mainly because he was a silent assassin of sorts who just wanted to focus on preserving justice in WWE.
While we don't think his character should be exactly the same, he needs to find that 'cold and calculated' personality within himself again.

Have Roman grow out his beard, not say a single word during promos, and only focus on taking out everyone in his path. We want him to be a modern-day terminator who doesn't associate with being a babyface or a heel because instead, he's just a badass.
This kind of move doesn't always work out perfectly, but with Roman, there really aren't that many alternatives left.
