Earth-77680

Earth-77680 is a reality similar to our Earth, to a point. An example is that a boy named Clark Kent had become Superboy, the world's only hero. However, this reality was destroyed in a multiversal war, and Clark was one of the few survivors, but became a madman called Superboy-Prime. Another survivor is the explorer Galan who was transformed into Galactus. When the reality was destroyed, beings called the Inheritors had taken what was left of the universe and remade it into a patchwork world called Loomworld, which became the basis for the later creation known as Battleworld.
