"In brightest day, in blackest night,
No evil shall escape my sight.
Let those who worship evil's might
Beware my power--Green Lantern's light!"
Hal Jordan is the greatest Green Lantern, an inter-galactic police officer and member of the Green Lantern Corps, chosen by the Guardians of the Universe for his ability to overcome great fear. The strength of his willpower allows him to wield the universe's mightiest weapon, a power ring controlled by his thoughts. In his secret identity he is a test pilot working for Ferris Aircraft where his boss Carol Ferris is also his romantic interest. Having turned into the evil Parallax during Emerald Twilight and died during Final Night, his soul became a host of the Spectre during Day of Judgment until his resurrection during Green Lantern: Rebirth. Although he is the most well-known Lantern, Alan Scott of the Golden Age is the original version of the character. Other Lanterns that have acted as his partners, successors or replacements at times have included Guy Gardner, John Stewart and Kyle Rayner. He is a founding member of the Justice League of America. Hal Jordan was created by John Broome and Gil Kane, first appearing in Showcase #22. (1959)
John Stewart is the third Green Lantern of Earth, formerly a sniper for the U.S. Marines and an architect. His power ring grants him the ability to make energy constructs guided by thought using his willpower. Originally given Green Lantern Corps membership after his predecessor Hal Jordan left the position, he has also shared the planet with his friends and fellow officers Guy Gardner and Kyle Rayner. Prior to her death at the hands of Star Sapphire, he was married to the alien Katma Tui. He has also been a member of the Justice League, the Darkstars and the Indigo Tribe. John Stewart was created by Dennis O'Neil and Neal Adams, first appearing in Green Lantern (Volume 2) #87. (1972)
Guy Gardner is a member of the Green Lantern Corps assigned to Earth, known for his brash attitude and machismo. He has also been a member of Justice League International. It is possible that history will determine Gardner to be the greatest Green Lantern of all time, although he is constantly in competition with his fellow Lanterns Hal Jordan, John Stewart and Kyle Rayner. Guy Gardner was created by John Broome and Gil Kane, and first appeared in Green Lantern (Vol 2) #59 (1968).
Kyle Rayner is the fourth Green Lantern of Earth, and a powerful member of the Green Lantern Corps serving as an honor guard. Originally given his power ring by Ganthet of the Guardians of the Universe after his predecessor Hal Jordan destroyed the Corps during Emerald Twilight, he was the last surviving torchbearer for many years until their return. The sentient willpower entity Ion possessed him and gave him incredible powers for a period of his career, but he was later briefly possessed by the fear entity Parallax as well. In his secret identity he is an artist, and uses his powers as the ultimate form of expression, constantly demonstrating his creativity and imagination during battle. He has also been a member of the Justice League, the New Titans, the Sinestro Corps and the Challengers from Beyond. Kyle Rayner was created by Ron Marz and Darryl Banks, first appearing in Green Lantern (Volume 3) #48. (1994)
Alan Scott is the original super-hero known as Green Lantern. The weapon he wields is a mystic power ring that turns his thoughts into energy constructs. Although he has never actually been a member of the Green Lantern Corps, his ring taps into the same power source that fuels them. His adventures originally took place during the Golden Age on Earth-Two, but he was introduced into mainstream continuity during the Crisis on Infinite Earths. His family includes his two children Jade and Obsidian along with his wife Molly Mayne. As one of the oldest heroes still active today, Alan Scott continues to fight against evil relentlessly and also acts as a mentor to the younger generation of metahumans in need of guidance. He is a founding member of the Justice Society of America and the All-Star Squadron, and also a member of Checkmate and the Sentinels of Magic. Alan Scott was created by Bill Finger and Martin Nodell, first appearing in All-American Comics #16 (1940). In 2011, James Robinson revamped Alan Scott as the openly homosexual Green Lantern of Earth 2.
