A comic book industry event: a new original ongoing superhero series from Mark Waid! Irredeemable dares to ask the question: what if the world's greatest hero decided to become the world's greatest villain? Heroes are being picked off one-by-one in a brutal and viscous assault. They never stood a chance, never saw it coming. A small cadre of heroes race against time and space to stay alive and turn the tables. A 'twilight of the superheroes'-style story that examines super-villains from the writer of Kingdom Come and Empire! Covers from John Cassaday and Dennis Calero.
