Earth's greatest heroes have defeated grave threats from Apokolips, but not at a grave price. Left in their stead is a group of young, untrained hereoes who pick up the pieces in the dusty aftermath. The Flash, Green Lantern, Hawkgirl and the Atom are humanity's nascent guardians, but not the ones we've all known and revered. These are different heroes, in a strange and foreign world with dangerous new villains. This is Earth 2.
