Captain America is a bada-- oh, excuse us for almost using a bad language word! He is a kicker of butt. There's no questioning that fact. He might not be the strongest hero in the Marvel Universe, but he's certainly the most courageous. Whether he's punching out Hitler, waging one-man wars or making gods and aliens defer to his command, Steve Rogers is never one to back down from a challenge. Cap will be facing one of his toughest challenges yet as he defies his government and challenges the likes of Iron Man, Spider-Man and Black Panther in Captain America: Civil War.
