Gil Kane in the context of "Comics Code Authority"

Green Lantern is the name of several superheroes appearing in American comic books published by DC Comics. They fight evil with the aid of rings that grant them a variety of extraordinary powers, all of which come from imagination, fearlessness, and the electromagnetic spectrum of emotional willpower. The characters are typically depicted as members of the Green Lantern Corps, an intergalactic law enforcement agency.

The first Green Lantern character, Alan Scott, was created in 1940 by Martin Nodell with scripting or co-scripting of the first stories by Bill Finger during the Golden Age of Comic Books and usually fought common criminals in Capitol City (and later, Gotham City) with the aid of his magic ring. For the Silver Age of Comic Books, John Broome and Gil Kane reinvented the character as Hal Jordan in 1959 and introduced the Green Lantern Corps, shifting the nature of the character from fantasy to science fiction. During the Bronze Age of Comic Books, Dennis O'Neil and Neal Adams introduced John Stewart, a new member of the Corps who was one of DC's first Black superheroes. Other notable Green Lanterns include Guy Gardner, Kyle Rayner, Simon Baz, Jessica Cruz and Jo Mullein.

The Green Lantern Corps is a law enforcement agency appearing in American comic books published by DC Comics. Co-created by writer John Broome and artist Gil Kane, the organization first appeared along with member Hal Jordan in Showcase #22 in 1959.

The agency patrols the farthest reaches of the DC Universe at the behest of the Guardians, a race of immortals residing on the planet Oa. According to DC continuity, the Green Lantern Corps have been in existence for three billion years. Currently operating amongst the 3600 "sectors" of the universe, there are 7204 members (known commonly as Green Lanterns). Each Green Lantern is given a power ring, a tool granting the use of incredible abilities that are directed by the wearer's own willpower.

John Broome (May 4, 1913 – March 14, 1999), who additionally used the pseudonyms John Osgood and Edgar Ray Meritt, was an American comic book writer for DC Comics. Along with Gil Kane, he co-created the supervillain Sinestro and the Green Lantern Guy Gardner.

Harold "Hal" Jordan, one of the characters known as Green Lantern, is a superhero appearing in American comic books published by DC Comics. The character was created in 1959 by writer John Broome and artist Gil Kane, and first appeared in Showcase #22 (October 1959). Hal Jordan is a reinvention of the previous Green Lantern, who appeared in 1940s comic books as the character Alan Scott. While Alan Scott had been designed after characters from folklore and mythology, Kane instead drew visual inspiration for Hal from Hollywood actor Paul Newman.

Hal Jordan is a former fighter pilot who works for Ferris Aircraft as a test pilot, a member and occasionally leader of an intergalactic police force called the Green Lantern Corps, as well as a founding member of the Justice League, DC's flagship superhero team, alongside well-known heroes such as Batman, Superman, and Wonder Woman. He fights evil across the universe with a power ring that channels willpower into energy constructs. As Green Lantern, Hal is the assigned protector of Sector 2814, which includes Earth, on behalf of the Guardians of the Universe. His ring grants him powers of flight, space travel, and the ability to create shields, weapons, and even his uniform. Hal's on-again off-again love interest is Carol Ferris, who has also at times served as his enemy Star Sapphire. Other villains in Hal's stories include the psychic mutant Hector Hammond, avatar of death Nekron, and his archenemy, Sinestro, Hal's corrupt former Green Lantern mentor.
