9. Nightwing
DC ComicsA character that someone like CM Punk could potentially play in a live action movie is Nightwing. As a supporting character of Batman, Nightwing wouldn't necessarily require the big name actor to portray him that a lead character of the Dark Knight's stature does require and, like Dave Bautista is doing with Drax the Destroyer in Guardians of the Galaxy, Punk could portray the sidekick. He's a dark character with kick-ass combat prowess, but his personality isn't quite as complex - and nor would he be expected to steal the movie if he was fighting alongside Batman - so Punk's responsibility would be lessened, which would certainly be welcomed by the man, given his lack of experience when it comes to acting. Of course, there are a number of characters who have gone by the name "Nightwing", and the most suited to CM Punk would probably be the adult Jason Todd (perhaps with Punk going on to become the Red Hood if his acting prowess stood up to the first test).
