Judgment Day was a limited series published by Awesome Comics from June to October 1997 written by Alan Moore and illustrated by Rob Liefeld, with additional art by Gil Kane.
This story features several characters created by Liefeld for both Awesome Comics and the Image Universe, including Supreme, Youngblood and Glory, dealing with the concept of superheroes being tried for murder.
Mark Thompson of Checker Publishing Group perceives Judgment Day in an introduction for the trade paperback as a spiritual followup to Moore's earlier work Watchmen for DC Comics, in that "if superheroes can commit murder, they can certainly be charged for the crime.
Moore would fully utilize the concept of a shared universe of literary characters in The League of Extraordinary Gentlemen with Kevin O'Neill and elements of his treatment of Glory were carried over into his America's Best Comics series Promethea.
The series deals with a metacommentary of the notion of retcons to super-hero histories as Alan Moore himself creates a new backstory for the characters of Awesome Comics, to replace the shared universe they had before Rob Liefeld left Image several years earlier.
The book alters reality when somebody writes upon it, and it has been acquired by many powerful figures over centuries, including the creature who would become Youngblood's Troll and Puritan immortal serial killer Deliverance Drue.
