Green Lantern is a superhero and an intergalactic police officer in the DC Universe. The weapon he wields is a power ring that translates his ideas into green energy using the strength of his willpower. He is a member of the Green Lantern Corps, an organization created by the Guardians of the Universe that has established thousands of members distributed throughout each space sector. There have been several assigned to the planet Earth in Sector 2814.

Alan Scott was the original Green Lantern of the Golden Age, and a member of the Justice Society of America. Although he is not a member of the Corps, he taps into the same energy using the magical Starheart. Hal Jordan was the first human Corps member, and is known as possibly the greatest of all time because he never gives up under any circumstances. He received his ring from his predecessor the dying alien Abin Sur, and was a founding member of the Justice League of America. The masculine Guy Gardner was chosen to be his back-up and potential replacement. John Stewart is the fourth, an architect and ex-soldier. Kyle Rayner became the last Green Lantern when the Corps was destroyed by Parallax during Emerald Twilight, but all of them have once again become active together since Green Lantern: Rebirth.

The original Green Lantern was created by Bill Finger and Martin Nodell in 1940, first appearing in All-American Comics #16. The current version of the character and his mythos were created by John Broome and Gil Kane, first appearing in Showcase #22. (1959)
