"The Infinity Syndrome!"
A Free-for-All Grows in Brooklyn!"
"Out of the Sky!"
"Green Light -- Black Shadow!"
First appearance of Infinity, Inc. The Ultra-Humanite's quest for power continues, as she brazenly announces impending attacks on three U.S. munitions plants scattered around the country. The Squadron must split up to protect the facilities, and are joined by the Guardian and Phantom Lady, plus gain a new ally in Amazing Man. The attacks are carried out by super-powered youths whose abilities strangely resemble those of the JSA, and even more mysteriously, the heroes who come into contact with them vanish into thin air!
