Reprinting CRISIS ON INFINITE EARTHS  #1. THE SUMMONING! This is it, the biggest, and arguably most important, event in the history of the DCU. A wave of unstoppable destructive force is sweeping across the multiverse and indiscriminately destroying everything in its path. Nothing seems able to stop it. The Crime Syndicate of Amerika (evil versions of the JLA) of Earth-3 die trying, along with their world. Batman receives an ominous warning from the Flash. Weather and natural disasters are out of control. An eclectic group of heroes and villains from around the multiverse are assembled to halt the death and destruction, and the being known as the Monitor may be the only one who can help them.
