In 1959, DC Comics editor Julius Schwartz reinvented Green Lantern as a science fiction hero. The new Green Lantern, named Hal Jordan, was empowered by alien masters to serve as an interstellar lawman and had many adventures set in outer space. His powers were similar to Alan's but he was otherwise completely unrelated—Alan Scott never existed as far as the new stories were concerned. Hal Jordan proved popular, but readers still had an interest in the old Green Lantern. Some years later, Alan Scott reappeared as a guest star in "The Flash" #137 (1963). To avoid continuity conflicts with the Hal Jordan character, Alan Scott and all his old stories were written as being from a parallel universe. For most of the 1960s and 1970s, Alan Scott made guest appearances in books belonging to Silver Age characters, visiting their universe through magical or technological means. In 1976, he appeared regularly alongside his Justice Society comrades in the revived "All-Star Comics" and later "Adventure Comics" in stories set in the 1970s. In 1981, DC Comics launched "All-Star Squadron", which featured Alan Scott and the Justice Society in a World War II setting.
