List of DC Comics characters: G

Galactic Golem
The Galactic Golem is a solar-powered creature created by Lex Luthor who is an enemy of Superman. Creator Len Wein said that he created the Golem "because I needed somebody Superman could hit! The problem with Superman's rogues' gallery was, they were all thinkers...they were scientists, or guys who built toys. With the Golem, he could hit Superman, and Superman could hit him back".

It only made two appearances: Superman #248 (February 1972) and 258 (November 1972). Afterwards, it was erased from continuity following Crisis on Infinite Earths.

Paul Gambi
Paul Gambi is a tailor in Central City who associates himself with the Rogues as seen in his first appearance where Flash pursues Top to his place of work. Following Top's defeat, Paul was arrested for being an accessory to Top. Paul Gambi later gives Flash a new suit. While testing it out, Flash sees that the loot of the villains that he fights goes missing.

An amnesiac Gorilla Grodd in human form stumbles into Paul Gambi's shop. To help with Gorilla Grodd's amnesia, Gambi starts to tell him the origins of the Rogues. After Flash's name triggers his memory, Gorilla Grodd persuades Paul to make him a Grodd suit. When the Rogues arrive and attack Grodd, he suddenly transforms back into a gorilla. After Gorilla Grodd is defeated, Solovar thanks Gambi for stalling before taking Gorilla Grodd back to Gorilla City.

Paul Gambi later created the "ultimate super-costume", which was first worn by serial killer Dell Merriwether until he was defeated by Flash and Green Lantern and got sentenced to the electric chair. However, the suit unexpectedly gained sentience and became indestructible.

In the "DC Rebirth" reboot, Flash unsuccessfully invades Paul Gambi's business to get information on where the Rogues are.

When the mission was a success, Deathstroke's Titans brought her to Brazil where Allegra lashed out against her father for abandoning her and used the UV rays in the sky to fry him.

Garguax
Garguax is a fictional character appearing in American comic books published by DC Comics. He is a mammoth-sized alien conqueror who was exiled from his home planet for his plans to conquer the universe. He came to Earth and invaded it with an army of Plastic Men. Mento found his ship and encountered him as he learned his backstory. When Mento didn't want to help Garguax with his goals, Garguax used his technology to brainwash him. After the Doom Patrol freed Mento from his mind-control, they fought Garguax. The Doom Patrol destroyed the ship which seemingly killed Garguax.

Garguax later appeared as a member of the Brotherhood of Evil alongside General Immortus at the time when they unleashed a Giant Jukebox Robot. Garguax pitches an idea to the Brotherhood of Evil to take over Earth. General Immortus supported his idea as he uses a device to turn anyone into diamond-skinned slaves that obey the Brotherhood of Evil's every command.

Garguax was with the Brotherhood of Evil when Madame Rouge planned to discredit Mento before his wedding to Elasti-Girl. Chief figures out the Rouge and the Doom Patrol caused the Brotherhood of Evil to retreat.

Following the Doom Patrol's apparent death, Garguax creates a giant android called Mandred to attack Chief and Beast Boy. When the Doom Patrol turns up alive as Brain tries to attack Chief, the Brotherhood of Evil manages to get away as Brain remotely broadcasts solar energy to revive Mandred.

The claims that Garguax made about being exiled from his homeworld were false as he turned out to be an agent of his homeworld's ruler Zarox-13. Garguax betrayed the Brotherhood of Evil after Zarox-13 arrived on Earth to conquer it. The Doom Patrol and the Brotherhood of Evil had to work together to defeat Zarox-13.

During the Invasion! storyline, Garguax attempted to join the alien alliance only to be rejected. This caused Garguax to join forces with the Doom Patrol to defend Earth from the upcoming alien invasion while secretly planning to take over Earth himself. Following the end of the alien invasion, Garguax resumed his plans to try to destroy the Doom Patrol. Chief called in a favor from the President of the United States to fire a laser satellite at Garguax's ship enough to obliterate him.

Garguax was sighted in Eclipso's vision among the characters that were eclipsed by him.

In the "Dawn of DC", Garguax is depicted as Emperor of the Moon.

Garguax in other media

After the signal finally arrives, Samuelson betrays and kill Garguax.

Garn Daanuth
Garn Daanuth is a fictional supervillain introduced in Warlord #62 (July 1982). His character is the major antagonist in both Arion, Lord of Atlantis and Arion the Immortal titles, serving as Arion's arch-enemy. He is affiliated with the Lords of Chaos, originally stated to be one of their agents. Later and modern revisions of the character instead mention him as a genuine Lord of Chaos. In the DC Universe, he serves as a prominent evil figure in ancient Atlantis's history and the former ruler of Mu, whose people culturally resemble ancient Egyptians. He is also alleged to be an ancestor of the Titans hero, Tempest (formerly Aqualad) and a distant relative to significant DC characters such as Aquaman, Ocean Master, and Zatanna through his brother's bloodline.

Fictional history
The eldest twin of Arion and son of Majistra and Calculha, he was instead raised by Majistra within the city-state of Mu. Taught black magic by his mother, Majistra raised him in accordance of a prophecy regarding two brothers in eternal conflict over the fate of Atlantis as an agent of the Lords of Chaos. Garn would gain a rivalry with Arion when his sacrifice of usurping the Zodiac Crystals from Majistra seemingly caused her death and bleached his skin, a reminder of his path as a dark sorcerer compared to Arion's light path and practice of white magic. Gaining a strong hatred for him, Garn would not learn of their true familial connection until centuries later and took over his mother's position as the leading figure of Mu, consolidating his wealth and sorcerous powers. Other stories mention that he was also an ally of Vandal Savage, helping Garn in his goal to undermine the ancient Atlantean government as a member of the Brotherhood of Light, the precursor to Savage's Illuminati secret society.

In the Arion, Lord of Atlantis title, Garn would be responsible for various atrocities in ancient Atlantean history, including invasions of other city-states, destroying the physical body of Calculha, his mind-control plot to usurp Arion's position as Lord High Mage driving a mentally damage D'Tilluh to commit suicide and a traumatized Wyynde becoming unresponsive, and the eradication of the Wyynde's tribe, the people of Khe-Wannantu. He was characterized often as a feared figure considered a genuine god. He also made a limited appearance in Warlord, revealed to be the ancestor of Aoife, whom was bestowed a major source of his power, Garn's circlet. Despite her evil legacy, she sided with Travis Morgan and used the powers bestowed from it for benevolent reasons. Although the image of Garn in his circlet (containing his will and personality) disapproved, he nevertheless stated his descendants are able to do whatever they pleased with their inherited power. In the Arion the Immortal series, it is detailed that after the destruction of Atlantis, Garn would relocate eventually into the Middle East and with his immortality but lack of powers, pose as a dictator of a small Middle Eastern army. When his magical abilities returned, he used them to bolster his forces until he was stopped by Arion.

A magical manifestation of his power would appear in the Young Justice comic title as a genie-like being known as Bedlam, possessing Matthew Stuart and making him a powerful foe possessing all of Garn's magical power. He is eventually defeated by both the Young Justice team and later by Impulse using time travel to deprive him of his magical powers. For a time, the speedster also gained his powers until the Phantom Stranger drained the magic from him.

Joan Garrick
Joan Garrick is a fictional character from DC Comics, a supporting character and romantic interest of Jay Garrick / The Flash.

The character was created by Gardner Fox and Harry Lampert, and first appeared in Flash Comics #1 (January 1940). She appeared in the cover alongside the Flash on the issue. She would remain the supporting character of the titular character throughout the Golden Age, and she was revived through the Silver Age in "Flash of Two Worlds" where she is revealed to be a part of Earth-Two.

Joan Williams was depicted as the college crush of Jay who Joan originally rejected. Later, Jay used speedster powers as a football star to impress Joan and later decided to be a superhero known as the Flash. The Flash helped Joan when the former's father was kidnapped. She would remain a girlfriend and confidante to the Flash. Unlike Lois Lane and Superman, Joan was always aware of the Flash's secret identity. The events of Crisis on Infinite Earths reconnected both Jay and Joan and the entire Keystone City citizens as being in a coma until Barry Allen revived the two. The couple ultimately married, and Jay retired from the Justice Society of America for a while until later returning to the group.

Joan was described as an essential part of the Golden Age Flash's life in later decades by Mark Ginnochio of Comicbook.com. Joan and Jay's marriage is cited as being "among the most popular of DC's earliest married characters" by Vaneta Rogers of Newsarama. Jim Beard in the book The Flash Companion wrote positively of the character's depiction by Sheldon Mayer which he felt was an example of "strong females" at the time. John Wells, in the same book, compared Gardner Fox's deriving of the character to other works of characters like Dian Belmont of Sandman, Inza Cramer of Doctor Fate and Shiera Hall of Hawkman that the female romantic interests were not just lovers but also confidantes of their respective superheroes as depicted at the time.

In the pages of "The New Golden Age", it was revealed that Joan and Jay had a child named Judy Garrick (also known as Boom) before she mysteriously vanished. After her memory of Boom is restored, Joan helps Jay settle in to their house. A flashback to 1963 had Joan kidnapped by Doctor Elemental as Flash and Boom worked to save her. It was also the day that Boom disappeared and that Joan lost her memory of her.

As Sand and Wildcat talk during a movie theater, two people behind them tells them to keep it down. They discover that the people are the Geomancer and Killer Wasp. The Geomancer and Killer Wasp are soon assisted in the ambush by Black Adam. Sand fights the Geomancer under the streets of New York City and defeats him.

Having accidentally killed the child of Hugo Thawne and Charlene Thawne, he had delivered twins afterwards and gave one twin to the con artists to cover his mistake which he lied as stillborn to Nora Allen and Henry Allen. Malcolm tracked Gilmore down for the truth to which Gilmore confirmed, resulting in Malcolm murdering the doctor in a rage.

Goldface
Goldface is an enemy of Green Lantern and the Flash. Goldface was created by Gardner Fox and Gil Kane, first appearing in Green Lantern (vol. 2) #38 (1965).

Keith Kenyon was a political sciences student who was exposed to a chest of gold that had been affected by toxic waste. As a result of exposure, he gained superhuman strength and invulnerability. The gold also gave him a golden glow, apparently as a side effect of the serum. Of course, being close enough to yellow meant that Green Lantern's power ring could not affect him directly, making him particularly formidable against the super-hero. Deciding to rebel against the wishes of his father, a prominent labor union organizer, he began stealing gold around Coast City, which led to his defeat by Green Lantern. He began to refine his criminal ways by wearing gold-plated armor and using a "gold-gun" which sprayed liquid gold. After many clashes with Green Lantern, Kenyon decided to change his motif and ruthlessly began taking over criminal empires. He eventually moved to Central City and became a foe of the second Flash (Barry Allen). Later on, Goldface reformed, married Amunet Black / Blacksmith, moved to Keystone City, and became the commissioner of Union 242. Over time, his elixir transformed his skin into organic gold.

Golden Eagle
Golden Eagle is the name of two fictional characters published by DC Comics.

Pre-Crisis
The original Golden Eagle was an orphan by the name of Charley Parker. Charley lived in the Midway City orphanage and idolized Hawkman. At one point he sent a letter to Hawkman describing his home-made "Hawkman" costume. In Justice League of America #109, Hawkman had been ordered back to Thanagar, thus resigning from the JLA. Golden Eagle debuted seven issues later in Justice League of America #116.

Parker himself explained that one day he had been wearing his "Hawkman" costume and fantasizing he was him when a strange light enveloped him turning his costume into an exact replica of Hawkman's costume. He also gained the ability to fly due to the replicated wings of his costume. Charley could at will change his street clothes into the Golden Eagle costume. The Justice League was called by the Midway City Police due to several incidents where criminals were dropped off at the police headquarters, captured by someone unknown who left a gold-colored feather behind—Hawkman's old modus operandi. The Leaguers investigated and ran into the Golden Eagle when they were attacked by Hawkman's old foe Matter Master, a man who carried a mentally controlled wand that could manipulate matter—for example, changing the heads of members of the Justice League into the heads of animals. The Matter Master thought that the Golden Eagle was Hawkman and mentally had the wand bring the Golden Eagle to his hidden lair. Mandrill figured out that his wand must have transformed Charley, acting out some sort of subconscious need for the villain to battle Hawkman, who had not been seen for months. At the end of the story, Charley was changed back into a normal teenager.

Charley was seen again in Justice League of America #117, as Green Arrow took him aboard the JLA satellite as a new "mascot" (similar to Snapper Carr).

He later appeared in Teen Titans #50–52 as a member of Titans West.

Post-Crisis
In 1989, Golden Eagle was retconned as a Californian surfer, unable to hold down a job. The previous connection to Hawkman was gone. Instead, his past was a mystery, just as the origins of his costume and his powers. Nonetheless, he remained connected to the Titans West, and was involved in the Titans Hunt storyline, where he was seemingly killed by a member of the Wildebeest Society.

Ch'al Andar
In Hawkman (vol. 4) #43, 2005, a new origin for Golden Eagle was introduced. Once an orphan in Midway City's Sisters of Mercy orphanage, Charley Parker bounced around from different foster homes and orphanages for the better part of his youth, learning life's hardships along the way. At sixteen, he became a drug courier for Mick Valdare, and was adopted by various foster families. Valdare paid these families handsomely, which allowed Parker, and by extension Valdare, to keep a low profile and to have a front if caught. Parker lived a rich and spoiled life full of fast cars, expensive clothes and beautiful women until he turned eighteen. Valdare fired him because he was no longer a minor. Parker, desolate, alone and without the luxuries he had grown accustomed to, considered suicide. Hawkman saved him and became a mentor for the young man. On the hero's recommendation, Parker went to, and found a job opportunity with, Carter Hall, a museum curator and Hawkman's secret identity. Parker accepted, and was soon exposed to other heroes, including Adam Strange and Hawkgirl.

Parker earned Hall's trust when he defended Hawkgirl from the Shadow Thief. Hall revealed his secret identity, gave Parker a Thanagarian battle suit that had been discovered by Adam Strange, and began training him to be a hero. Parker, now known as Golden Eagle, finally felt he had a purpose in life. Carter Hall had to leave Earth and left Charley to his own devices. Parker eventually hooked up with the Titans West, but after that team disbanded, he returned to a slacker lifestyle, surfing and performing the occasional odd job to earn money. After discovering that renting out his services as a hero didn't generate sufficient income, he retired the Golden Eagle identity. Deathstroke asked him to track down some missing Teen Titans members at the beginning of the Titans Hunt storyline. During this time, while fighting alongside Aqualad against the [Wildebeest Society, Parker was choked to death. A statue of Golden Eagle is in the memorial section of Titans Tower. Suddenly, he was miraculously revived by the Nth-Metal within his Thanagarian armor, claiming to have rediscovered his motivation to be a force for good.

This story proved to be a ruse, and Parker's true colors and motivations appeared in Hawkman (vol. 4) #44–45. When Carter Hall was seemingly killed in battle, Parker claimed the right to his legacy, becoming the new Hawkman. He managed to win the friendship of Kendra, and claimed to be the "true" Hawkman's son (he considered Hall a "false Hawkman"). He showed Kendra a Thanagarian ship he had built using blueprints stored in his Golden Eagle armor, and asked her to follow him to Thanagar. When she refused both his proposal and sexual advances, Parker beat her and exposed the truth about his relationship with Hawkman. On the verge of killing Kendra and replacing her with a Thanagarian maiden, "more suited to his tastes", Parker was confronted by a very much alive Carter Hall, who miraculously returned for a final showdown with his former protégé.

In the subsequent fight between the two Hawkmen, it was revealed that Parker was indeed the son of a Hawkman, the villainous Fel Andar, the spy sent from Thanagar in the wake of the Invasion, the military alliance against Earth, and Earth woman Sharon Parker. Parker had carefully planned the death of Carter Hall, creating an alliance among many of Hawkman's foes. He drugged Hall to beat Hawkgirl, to make her betray him just as (Parker believed) the Thanagarians and Earth-men had betrayed his father. Hall beat his foe and sent Parker, along with a recording of his confessions, to Thanagar to be judged for his crimes.

Arriving on Thanagar in the wake of the Rann-Thanagar War, he earned a pardon for his crimes and was instated as a Wingman leader dispatched on Rann. Half-blinded by the severe beating he suffered at Hall's hands, Parker was now equipped with a cybernetic eyepatch over the left eyesocket and a new suit of armor. In battle with Hawkman, Hawkgirl and Adam Strange, Parker was finally reunited with his father, Fel Andar, who had now forsaken his evil plans of domination and sought only forgiveness and to do what is right for Thanagar. He pleaded with his son to follow the same path. Parker foregoes a further attack on Hawkman and Hawkgirl, but it is unknown yet what path he will take. His father Fel Andar was killed during an encounter with Blackfire.

After the alien Forerunner Viza Aziv was dismissed from The Monarch's multiversal army, she found herself in space aboard a space pirate ship she promptly took as her own. Shortly afterwards, a Thanagarian fleet in search of the ship's original captain demanded her surrender, to which she challenged them and their leader to honorable combat. Their leader was Golden Eagle. Viza invoked the law of choice, a custom on her home world enabling the victor of a battle to take any prize they wanted. After she defeated him and his troops, she decided to take him as her prize, forcing him to serve as her sex slave aboard her pirate ship. When Forerunner finds a planet to call her own, she allows Golden Eagle to leave.

Gorilla Boss
Gorilla Boss is a fictional character appearing in American comic books published by DC Comics.

George Dyke is a crime boss who was executed in a gas chamber, with his brain being transplanted into the body of a gorilla. Due to longer being able to speak, he uses a pad and pencil to order Doc Willard and his henchmen to procure the required funds so that he can have his brain placed in the body of Batman and Batman's brain placed in the body of the gorilla. Gorilla Boss committed a series of crimes and claims that once Batman's brain is in the body of the gorilla, the police will mistake him for the culprit and kill him. Batman escapes Gorilla Boss's grasp and is chased up the building until Gorilla Boss falls to the street where he remains unconscious by the time Batman makes it to the ground. The truth about the gorilla having George Dyke's brain and the experiments that allowed this to happen were revealed.

An alien race later places the brain of Gorilla Boss into the body of a chlorophyll-sapping alien beast as part of their plans to take over Earth. Superman and Batman were able to thwart the alien invasion, but Gorilla Boss escapes with Doc Willard. A witness to Whisperer's crime spree was later subjected to a brain surgery by Doc Willard to place Gorilla Boss' brain in him. When Batman was using a machine to get the information on Whisperer out of the witness, it was starting to reveal Batman's true identity causing Superman to destroy it. They both figured out that Doc Willard was responsible for the brain switch. Batman later finds Willard in a mentally-deranged state. When interrogating him at the Batcave, he revealed that a "yellow alien" took Gorilla Boss' brain. Batman deduces that Sinestro was responsible. Superman finds that Sinestro is using Gorilla Boss' brain to increase his power supply. Superman thwarts this plot. While Sinestro was sent back to Qward, Doc Willard is remanded to Arkham Asylum while Gorilla Boss' brain is placed back in its place in the Batcave.

By the time Gorilla Boss' brain is back in his gorilla body, Gorilla Grodd mind-controls him, Congorilla, Djuba, Monsieur Mallah, and Sam Simeon. After Gorilla Grodd's psychic abilities inadvertently damage his brain, Gorilla Boss and the other apes are freed from his mind-control.

Abner Girdler was a specialist in urban planning and new transportation technologies at Technodyne. He proposed to build a monorail in Manchester, Alabama, but the project was scrapped at the last minute by the county transportation commissioner, Clifton Burdett. Having lost the lucrative contract, Technodyne faced bankruptcy, and CEO Leo Nordstrom fired Girdler. Burdett later ran for mayor, and Girdler decided to sabotage his election by donning the guise of Gridlock, equipped with technology able to steal the kinetic energy from people and objects, leaving them in stasis for about an hour. Gridlock kidnapped Nordstrom and froze most of Manchester, but was eventually defeated by Impulse.

Gridlock II
He first appears in Bat-Mite #2 (September 2015) and was created by Dan Jurgens and Corin Howell. He is a villain who is stuck in the past, despises youth culture and seeks to stop the future from coming.

Griffin
Griffin Grey is a fictional character appearing in The Flash created by Danny Bilson and Paul De Meo set during One Year Later.

Griffin was a friend of Bart Allen while in Keystone City until he was caught in an explosion at work; he found out he had enhanced speed and strength, and he became a hero, but only for the glory of it coining himself "Griffin" as his name. However, his celebrity status did not last and the powers made him age faster, and he looked like an old man in days. He tried to find the secret of what kept Jay Garrick young, but could not. He then became a villain, and during a fight with Bart/Flash, he was overpowered and died.
