The current (and some would say greatest) incarnation of the World's Greatest Super-Heroes is the focus of our climactic issue. The newest League faces the JLA's oldest threat: the shape-changing Appelaxians, the very first foes the JLA ever faced.

Earthquakes, floods, tidal waves all threaten to scour humanity from the Earth.
