In 1986, the editors at DC Comics decided that all its characters should exist within the same setting and effected this change with the "Crisis on Infinite Earths" miniseries. Alan Scott now shared the same fictional world as Hal Jordan. DC Comics decided to write the character out of continuity in a one-shot book entitled "Last Days of the Justice Society", in which he was "forever" trapped in an extra-dimensional realm. The character was brought back in the 1990s due to fan interest. Rather than update Alan Scott as a contemporary young hero as had been done with Batman and Superman, Alan Scott was instead written as a veteran of World War II with a magically prolonged lifespan. To distinguish Alan Scott from Hal Jordan, his superhero codename was for a time changed to "Sentinel" and he lost his magic ring, manifesting his powers through his glowing hands instead. In "JSA" #50 (2003) he regained his classic codename and ring, though he remained apart from Hal Jordan's Green Lantern Corps. He was a regular character in "JSA" and "Justice Society of America".
