I think Roman Reigns would fit perfectly. He's got the size, and the look for it. Being the badass guy just requires decent mic skills since basically you're gonna be like, "You wanna fuck with me, not if I fuck with you first" kinda mic stuff(yes I know it's not PG but it's just an example). I think his move set adjusts well to that as well. It's a simple gimmick, that a love of people love. I'm sure Roman wouldn't mess it up, since I do like the part in the shield he is in right now as the muscle. His screams and power attacks are great, and can adjust well to the gimmick.
