Justice League of America (1960-) #190

Armed with Hawkman’s repellor-discs, which prevent Starro from taking control of them as he has their fellow members, Batman, Aquaman, the Flash, Hawkman, Hawkgirl, Elongated Man and Zatanna mount a counterattack on Starro and his mind-slaves. If they fail, the authorities may be forced to destroy New York to prevent the spread of Starro’s endlessly replicating duplicates. The problem is solved by two “victims” who escape Starro’s control. Red Tornado, whose computer mind is not affected as a human brain would be by Starro’s influence, blacks out the city, leaving Starro without an energy source, and Terry Watson, by hiding in a food freezer, enables Hawkman and Hawkgirl to discover that intense cold can not only free the alien conqueror’s victims, but also defeat Starro himself. Firestorm and Green Lantern, their minds freed from Starro’s control, bombard him with ice and freeze him solid, while Zatanna’s magic chills the air, disposing of the duplicates across the city.
