In 1986, Alan Moore changed the face of comics for generations to come when DC released his iconic superhero deconstruction series, Watchmen. Widely regarded by many to be the greatest comic book story of all time, Watchmen follows a team of retired, flawed superheroes who got back into action to solve the murder of one of their own. Almost 40 years later, the story's main villain, Ozymandias, is still DC's most interesting villain.
