Irredeemable is an American comic book series written by Mark Waid, drawn by Peter Krause and Diego Barreto, and published by Boom! Studios. The series follows the fall of the world's greatest superhero, the Plutonian, as he begins slaughtering the population of Earth. His former allies, the superhero group The Paradigm, attempt to find a way to stop his rampage while dealing with their own feelings of betrayal and hopelessness. Irredeemable #1 premiered in April 2009, and the series ended in May 2012, after thirty-seven issues and one special. Peter Krause was the artist for the first twenty-four issues, after which Diego Barretto took over as artist. A spin-off, Incorruptible, was released in December 2009, which follows one of the Plutonian's greatest enemies, Max Damage, on his journey to become a superhero in the wake of Plutonian's fall. Waid brought both series to a conclusion in May 2012.
