Coming off their previous project, Earth X from Marvel Comics, Alex Ross, Jim Krueger, and Doug Braithwaite started on Justice, a 12-issue bi-monthly series. Ross described the series as a full-on superhero war, the Super Friends versus the Legion of Doom, to the death. In many ways, Justice is a follow-up to Ross’ and Paul Dini‘s The World’s Greatest Super-Heroes.
Ross had stated that, following Kingdom Come, he wanted to break away from the 1990s fixation with superhuman wars, and focused on The World’s Greatest Super-Heroes. It was only following that that he could return to the war stories he is known for, like Kingdom Come.
