Green Lantern is the name of several fictional characters, superheroes appearing in comic books published by DC Comics. The first (Alan Scott) was created by writer Bill Finger and artist Martin Nodell in All-American Comics #16 (July 1940). The best-known is Hal Jordan[citation needed], created by John Broome and Gil Kane in Showcase #22 (Oct. 1959). Each Green Lantern possesses a power ring that gives the user great control over the physical world as long as the wielder has sufficient willpower and strength to wield it. While the ring of the Golden Age Green Lantern (Alan Scott) was magically powered, the rings worn by all subsequent Lanterns were technological creations of the Guardians of the Universe, who granted such rings to worthy candidates. These individuals made up the intergalactic police force known as the Green Lantern Corps Each of Earth's Green Lanterns has been a member of the Justice Society of America or the Justice League, and John Stewart was featured as one of the main characters in both the Justice League and the Justice League Unlimited animated series. The Green Lanterns are often depicted as being close friends of the various men who have been the Flash, the most notable friendships having been between Alan Scott and Jay Garrick (the Golden Age Green Lantern/Flash), Hal Jordan and Barry Allen (the Silver Age Green Lantern and Flash), and Kyle Rayner and Wally West (the modern age Green Lantern and Flash), as well as Jordan being friends with West
