Once upon a time there used to be a Crisis that destroyed a infinite number of alternate earths and then the universe was reborn into one single earth where the Heroes are now facing a villain attack in the planet Earth, a war between Rann and Thanagar which involves the Green Lantern Corps and Brother Eye taking control of the OMAC Project with the protocol of eliminating every Metahuman in the world, but behind this Crisis is Alexander Luthor Jr of Earth-3, Superman of Earth-2, Lois Lane of Earth-2 and Superboy Prime who survive the previous Crisis and wants to replace this Earth with the alternate Earth called Earth-2 (home of the Golden Age Superman) to stabilize balance in the Multiverse and to save Lois Lane before she dies of old age.
