When the alien conquerors known as the Imperium invade the planet Earth, not even the World's Greatest Heroes could stop them. Against this single threat, this group of disparate and fiercely independent loners found that not even raw power, unequaled cunning, blinding speed, and unbreakable will were enough.
In the end ... it took all of them fighting together as one to vanquish the Imperium. And on that day; the forces of evil, chaos, and destruction inadvertently created one unbeatable league of justice.
