 Sylvester then joined the JSA, at which time a then-injured Starman loaned him his cosmic rod (it was later revealed that Starman wanted the young man to become his heir as neither of his sons expressed interest in carrying the mantle).Soon afterward, the Kid refined the technology of the rod, devising a belt with similar powers such as energy projection, flight and matter transmutation.Eventually, Sylvester temporarily retired from superheroics to reclaim his inheritance and his father's business, plus movie studio Stellar Studios, from his corrupt nephew, who was using those funds to run his own evil organization, Strike Force.
