Back in the late 1980s to the early 2000s, there were superheroes across the world, protecting people from the forces of evil. Those heroes were Batman, Superman, Wonder Woman, Flash, Aquaman, Green Lantern, Hawkgirl, Cyborg, and Martian Manhunter. But after an explosion from a terrorist organization that killed his wife, Superman goes on a rampage, and hunts down people who may be involved with the organization. This leads to Batman, Wonder Woman, and the others fearing that Superman may kill someone, leading them to come out of retirement and trying to stop him before something goes wrong.
