The Super Squad
Shortly after returning to active service, the JSA discovered that several more of their old adversaries had come out of retirement as well, notably Brainwave and Per Degaton. Brain Wave, harboring a new body, was the architect of a series of geological disasters that threatened to destroy the entire world. The JSA responded to the crisis, but found assistance in the form of three younger heroes: Robin (Earth-Two) , the Star-Spangled Kid I, and a new hero named Power Girl. At Power Girl's suggestion, these heroes became an auxiliary detachment of the JSA called the Super Squad.
