JSA: Our Worlds at War

"OUR WORLDS AT WAR," Part 18. It's time to call in the reserves...all of them! When President Luthor sends the JSA to take out Imperiex's base, a battleship the size of Jupiter, Sand fills out the ranks with Power Girl, The Ray, the Shining Knight, and a dozen others. But the horrible secret of Imperiex's power may prove too much for the JSA allies to handle.
