Part 2 of a 3-part story of the World's Greatest Super-Heroes by the dream team of writer Grant Morrison and SUPERMAN/BATMAN artists Ed McGuinness and Dexter Vines! With the whereabouts of the JLA still a mystery, Batman is forced to face off against Gorilla Grodd and his army...with the aid of a Justice League of the Dark Knight's own design!
The JLA track Black Death through the Earth of the infant universe of Qwewq, a world that developed without super-heroes. Squire continues to try and reach the JLA. Activating the robotic JLA, Batman returns to Earth via Boom Tube.
On Earth, Grodd consumes one of the Ultramarines. The Marines fall to mind control parasites. Batman returns, and the faux-League are made short work of by the forces of Grodd's Ultramarines.
Squire reaches the real League and they return to Earth by Boom Tube.
