Synopsis
The JLA complete collecting the items on the list but are shocked when they discover George is also part of the trade. They protest but he insists on going in order to save humanity. The Treasurers then give them a crystal which when detonated high in the atmosphere will re-seed the Earth with Element X.
But it is in fact a trick and the substance that rains down all over the Earth begins to turn humans into animals, turning them against each other. This was all a plan to make the conquest by a race now as the War-Kohns easier. The aliens attack the JLA satellite and believe that they have killed the league but this is a ruse as the league decide what to do next.
