Green Lantern Corps in the context of Kyle Rayner

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.

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.

Guy Darrin Gardner, one of the characters known as Green Lantern, is a superhero appearing in American comic books published by DC Comics, usually in association with the Green Lantern Corps, of which he is a member. Gardner has also been a member of various incarnations of the Justice League.

Gardner has been substantially adapted into media outside comics, primarily in association with the Green Lanterns. James Arnold Taylor, Diedrich Bader, and Troy Baker have voiced the character in animation. Matthew Settle portrayed the character in the television pilot Justice League of America. Nathan Fillion portrays Gardner in the DC Universe film Superman, a role he also plays in the second season of the television series Peacemaker and the upcoming television series Lanterns.

Simon Baz, one of the characters known as Green Lantern, is a superhero appearing in American comic books published by DC Comics, created by writer Geoff Johns and artist Doug Mahnke. Baz is an officer of the Green Lantern Corps, an extraterrestrial police force. The character made his debut in 2012 following The New 52 relaunch as part of its Green Lantern story arc "Rise of the Third Army", in which he replaces Silver Age hero Hal Jordan as the Green Lantern of Earth's sector.

Prior to his debut, the character made an unnamed cameo in The New 52 Free Comic Book Day Special Edition #1. DC later added Baz to its flagship team-up title Justice League of America in 2013.

Jessica Cruz, one of the characters known as Green Lantern, is a superheroine appearing in American comic books published by DC Comics. Created by Geoff Johns and Ethan Van Sciver, she is a member of the Green Lantern Corps and Justice League, as well as the first female human Green Lantern. Her first full appearance takes place in Justice League (vol. 2) #31 (August 2014), which is also her first cover appearance. Cruz currently operates out of Portland, Oregon.

Jessica Cruz has appeared in various media outside comics, including television and films. Myrna Velasco, Cristina Milizia, Dascha Polanco, Jeannie Tirado, and Diane Guerrero have voiced the character in animation

Green Lantern is a 2011 American superhero film based on the character from DC Comics. It was directed by Martin Campbell, from a screenplay by Greg Berlanti, Michael Green, Marc Guggenheim, and Michael Goldenberg. Ryan Reynolds stars as Hal Jordan / Green Lantern, a test pilot who is selected to become the first human member of the Green Lantern Corps, an intergalactic police force. He is given a ring that grants him superpowers and must confront Parallax, a being who threatens to upset the balance of power in the universe. The film also stars Blake Lively, Peter Sarsgaard, Mark Strong, Angela Bassett, and Tim Robbins.

The film first entered development in 1997; progress remained stalled until Berlanti was hired to write and direct in October 2007. Martin Campbell was brought on board in February 2009 after Berlanti was forced to vacate the director's position. Most of the live-action actors were cast between July 2009 and February 2010, and filming took place from March to August 2010 in Louisiana. The film was converted to 3D during its post-production stage. This was the first DC film since Catwoman (2004) not to be involved with Legendary Pictures.
