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? Does Plutonion's past hold the key to his current deadly rampage? Or does it even matter? A 'twilight of the superheroes'-style story that examines super-villains from the writer of Kingdom Come and Empire! Covers by John Cassaday and Dan Panosian.
