The epic story that blows the Marvel Universe apart. When a tragic battle occurs, killing hundreds of people, the U.S. government demands that all super heroes unmask and register their powers. To Tony Stark – Iron Man – it’s a regrettable but necessary step. To Captain America, it’s an unbearable assault on civil liberties. So begins the Civil War. Based on the smash hit graphic novel – over half a million copies have sold in print and digital formats.
