Personally, I feel that when superhero titles have multiple bearers (Green Lantern being the perfect example) I feel the films ought to pass the torch from film to film. So if Hal Jordan was in the first, I wouldn't mind Kyle Rayner being in GL2 and then, in the movie closest to Justice League (fat chance, frankly, despite all their big talk), John Stewart could pick up the ring. That way it happens organically. Anyway, enough about DC.
I'd like to know if Black Panther could adequately fall into the MCU continuity or if he'd have to be a stand-alone character. How does he match up with, say, Captain America in terms of superhuman ability? Anyone short of that probably ought to steer clear of the likes of Thanos, is what I'm getting at. The Avengers will have to keep upping the ante and they need heroes who can keep up with that pace.
