G'nort was a member of the Green Lantern Corps and later a Darkstar. He resembles a humanoid dog and is thoroughly incompetent and generally disliked by other heroes; in fact, he is usually portrayed as being a loser and used as comic relief. He was a member of the Justice League Antarctica. Despite his comedic appearance, he has become somewhat of a cult favorite among comic book readers.
Hal Jordan explains that G'nort became a Green Lantern due to the influence of his relative who was a famous member of the Lantern Corps. Despite his obviously limited intelligence (not intelligent enough to read a map) and profoundly lacking tactical judgment, the character is consistently depicted as brave, loyal, and honorable. This fact is overlooked by most heroes, although Superman has pointed it out on occasion.
Early in his career, G'nort becomes inadvertently mixed up with the League's battle against the Manhunters. Recognizing G'Nort's general incompetence, the Corps had given him an uninhabited sector of space to patrol. The fact that the region was uninhabited also suited the needs of the Manhunters, who set up their home planet in G'Nort's sector. G'Nort joined Hal Jordan, Superman, and other Justice League members in an assault on the home world, although G'Nort's main contribution was getting stuck in the planet's ventilation system.
Working with the League
G'nort's arch enemy, the Scarlet Skier (a take-off of Marvel's Silver Surfer), is described as being the only felon G'nort ever managed to apprehend in his entire career. Also an idiot, the Skier was mistaken for a pan handling homeless person when traveling in the subway.
G'nort goes on a mission to rescue Mister Miracle from the interstellar trader Manga Khan. Traveling in a spaceship, G'nort works with Big Barda, Martian Manhunter, and Dmitri of the Rocket Reds. They chase down Khan and survive an assassination attempt by his hired killer Lobo.
Both G'nort and the Skier were founding members of Justice League Antarctica, created by Maxwell Lord for the purpose of keeping both them and the reformed Injustice League out of his way.
G'nort assists the League, this time consisting of Manhunter, Crimson Fox and Ice, when Mr. Nebula, the Skier's old boss, turns his dangerous, cosmic-powered attention to Earth.
G'nort sees himself as a "Green-Lantern-at-large", not bound to a single space sector. His most successful mission (apart from capturing the Skier) has been when a gang of interstellar bank-robbing humanoid cats surrender as soon as he appears.
Eventually it is discovered that both G'nort and his uncle G'newman were actually given their rings by the Poglachians, who posed as the Guardians of the Universe while the real Guardians were with the Zamarons. A race of clowns, the Poglachians gave the rings to beings they thought would use them in amusing ways. They were actually pawns of the Weaponers of Qward, who hoped to discredit the Green Lantern Corps by having the name associated with idiots. G'nort works with Guy Gardner, ending up in Qward itself, though G'nort loses his Qwardian-powered ring. Their confrontations against a Qwardian Sinestro cult goes badly. Faced with the threat of his beloved uncle being killed, G'nort gives up the location of Hal Jordan.
G'nort presumably lost his ring during Emerald Twilight and subsequently (like many former Lanterns) joined the Darkstars. He still wears his Darkstar uniform long after the organization collapses, when he is captured by Manga Khan, who attempts to trade him to Maxwell Lord in exchange for L-Ron. The entire situation goes badly, resulting in the near destruction of Earth. G'Nort is set free after Maxwell Lord and Sue Dibny hold Khan for ransom. L-Ron returns with Khan.
G'nort was seen as the sole member of Super Buddies Antarctica, exactly where Maxwell Lord wants him. For a time, G'Nort lives behind Guy Gardner's New York 'Warriors' bar. He appeared later in the mini-series "Guy Gardner: Collateral Damage", where his homeworld had been destroyed by the Rann-Thanagar War. The character was portrayed more serious in this story, suffering heavily from the loss of his family.
As of Green Lantern: Sinestro Corps Secret Files & Origins #1, G'nort is listed as "Presumed Dead." When asked whether G'nort would be making an appearance as a member of the Black Lantern Corps during Blackest Night at San Diego Comic Con 2009, Geoff Johns replied that the character was not dead and was still considered missing in action.
I Can't Believe It's Not the Justice League
In the alternate dimension visited by the Super Buddies in the I Can't Believe It's Not the Justice League, populated by twisted counterparts of the main universe characters, G'nort is a rampaging flea-infested giant, whose body is used as a battleground.
Justice League Unlimited
In the Justice League Unlimited comic spin-off G'nort starts his career as a regular Green Lantern Cadet, nephew of the famous G'Newt but lacking any skills and talents. He is brought to Qward by John Stewart along with other Lanterns to stop Sinestro's last plan to destroy Oa by flaring over the planet with antimatter bursts. Despite Boodikka's prejudices against a rookie, G'nort is able to hold his own on combat, and uncover G'Newt himself as Sinestro's partner and accomplice. The Guardians, impressed by his courage, grant him the former sector of the deposed G'Newt to patrol.
In an alternate universe ruled by evil versions of the 'Planetary' heroes, G'Nort's corpse is one of many on display in the Planetary headquarters.
G'nort appears in the Batman: The Brave and the Bold episode "The Eyes of Despero" voiced by Alexander Polinsky. He, Sinestro, and Guy Gardner work with Batman to stop Despero. His backstory is the same as originally presented in the comics, as Sinestro mentions G'nort's uncle had "pushed" him through Lantern training. Though G'nort is initially presented as somewhat incompetent, he proves vital in helping Batman stop the brainwashed Mogo by draining Mogo's internal Lantern Battery. Despite forgetting the Green Lantern oath necessary to begin the process, he comes through upon consulting the "cheat sheet" written on his arm. After Batman compliments him twice and helps G'nort earn the respect of the Corps, he jumps into his arms to lick him, only to get a reprimand ("No licking."). G'Nort makes a non-speaking cameo in the episode "Revenge of The Reach", wherein he is blasted by the mind-controlled Blue Beetle.
