List of Marvel Comics characters: G

Gaia
Gaia, also known as the Guardian of the Universal Amalgamator, is a fictional superhero, depicted as possibly being a mutant or extraterrestrial. Created by Larry Hama, she first appeared in Generation X #37.

Not much is known about Gaia's origin besides her having spent thousands of years chained to the Universal Amalgamator at the end of Time, a device that would be used to merge all sentient consciousnesses into one being. Gaia was apparently the safeguard that was supposed to prevent the Amalgamator from being activated by malicious people. She even claimed that her entire galaxy was wiped out at one point for her refusing to activate the Amalgamator.

However, when M-Plate, the synthesis of Emplate and M, tried to have Synch use his power to tap into Gaia's and activate the Amalgamator, Everett refused. The Citadel of the Universal Amalgamator began to crumble around them and Generation X wanted to leave, but Synch went back, along with Penance, to save Gaia. Banshee thought him lost but Gaia knew of a secret portal that was hidden underneath the altar that she had been chained to and—coincidentally—led back near the Academy. With the Amalagamator destroyed, Gaia was freed from her responsibility and ran off to live a life that was now her own.

When she was seen next, she had gotten into an accident with a sports car and had pink hair. The policeman who came to the wreck knew of the Academy, and suggested that she be put into their hands. She lost some of her abilities to the Shadow King's telepathic shockwave, and stayed with Gen X, hoping to sort out that difficulty with their help.

Gaia formally enrolled in the Xavier's School for Gifted Youngsters, but left after a short time, saying that she wanted to experience Earth, not just learn about it.

It is unknown if Gaia was one of the 90–95% of mutants who lost their mutant powers on M-Day.

Gaia has been shown to have a degree of superhuman strength, limited invulnerability, telepathy, psychokinesis, and the ability to draw on an extra-dimensional source of matter and energy in order to create or reshape anything according to her will. She is capable of warping reality to a limited degree, although she is largely inexperienced with this power and its use requires great concentration. Gaia also appears to be either extremely long lived or completely immortal as she stated that she visited Earth 600 years ago and still has the appearance of a teenage girl.

Ganymede
Ganymede is a fictional extraterrestrial superhero in the Marvel Comics Universe. Her first appearance was Silver Surfer Vol. 3 #80 (May, 1993).

Ganymede is the last surviving member of a race of warrior women known as the Spinsterhood, a group which was formed with the sole purpose of destroying the cosmic being known as Tyrant. After a centuries long cyrogenic sleep, she awakened to find Tyrant's servants kidnapping powerful cosmic entities in order to drain their powers for their master's own ends. Mistaking Silver Surfer for a minion of Tyrant, Ganymede attacked him and the two fought until Tyrant's minions ambushed and kidnapped them both.

Ganymede, along with Tyrant's other hostages, Silver Surfer, Terrax, Morg, Beta Ray Bill, Gladiator and Jack of Hearts escaped their imprisonment and attacked Tyrant together, only to fail miserably. Galactus arrived and ended the battle. After that, those involved went their separate ways except for Ganymede, who decided to stay with Jack of Hearts to help nurse him back to health after his selfless sacrifice that freed his fellow captives. Ganymede and Jack of Hearts had a few adventures together, wherein they struck up a romantic relationship. Jack of Hearts would later become a member of the Avengers. Ganymede, however, has been absent from any comic tales for about 10 years.

Inhuman
Gauntlet is a member of the Dark Riders, employed by Apocalypse, and is one of the Inhumans. He is fitted with a cybernetic gauntlet, high-powered weapons, and wears a mechanical device over one eye used for tracking and scoping out prey.

Gauntlet first appeared in X-Factor #65 and was created by Jim Lee, Chris Claremont and Whilce Portacio.

Gauntlet made an appearance in the X-Men Evolution episode "Target X" voiced by Mark Gibbon.

Geist
Geist (Nikolaus Geist) was a supervillain in Marvel Comics. He was created by Archie Goodwin, and first appeared in Wolverine #17 (November 1989).

Geist had been an adviser for Adolf Hitler during World War II, and gave Hitler ideas on how to run the concentration camps. To escape war crime punishment, he used German rocket scientists to help the OSS. He later participated in questionable CIA operations. During Wolverine #17 and later issues, however, he was an adviser to President Caridad, of the fictional South American country Tierra Verde. Caridad wanted Geist to create a superhero and champion for Tierra Verde, much like Captain America. He was experimenting on humans with a special crop of cocaine, which drove the victims mad. His main guinea pig was Roughouse. Wolverine learned of this, and even though Roughouse had been his enemy, he helped him escape.

Wolverine cut off Geist's metal shell, leaving him to die. However, Tierra Verde allowed CIA agents to bring Geist out of the country allowing subsequent repairs. Soon after that, Magneto caught up with him and brought him into an abandoned house, exacting his revenge for the death of Magnus' wife and supposedly killing him off-panel.

Geist was a cyborg, but had no superpowers. He was encased in a metal shell simply to survive, because he was so old.

Annie Ghazikhanian
Annie Ghazikhanian is a fictional nurse who worked with the X-Men. She first appeared in Uncanny X-Men #411, and was created by Chuck Austen and Ron Garney.

When the X-Man Havok is found in a comatose state, she is assigned to his care. Despite Havok's only real reaction being an energetic appreciation of the sunlight, she develops romantic feelings towards him. When the X-Men discover he is still alive (as he was presumed dead), Cyclops, Alex's brother, comes to collect him. Annie and her son soon move in.

While Annie is a normal human, her son, Carter Ghazikhanian, is a mutant. Annie has some anti-mutant prejudices, but she tries getting over them. She developed a personal friendship with the X-Man Northstar, and kept secret his romantic feelings for Iceman. She is seen many times administering to wounded X-Men.

When Havok wakes from his coma he pursues a relationship with Annie, even after becoming engaged to Polaris. Havok later leaves Polaris at the wedding altar, further damaging the woman's already-shaky mental state. He and Annie have a romantic relationship (despite her occasional flirts with Iceman) until she leaves the mansion. She fears for her son's safety because of supervillain attacks upon the mansion.

Carter Ghazikhanian
Carter Ghazikhanian is a fictional mutant character in the Marvel Comics Universe. His first appearance was in Uncanny X-Men #411, created by Chuck Austen and Ron Garney.

Carter is the son of Annie Ghazikhanian, the former nurse at the Xavier Institute. Since their move to the school, Carter struck up a friendship with the young aquatic mutant Sammy, alias the Squidboy. When Carter tries to help Alex Summers, the X-Man known as Havok, from his coma, something strange occurs which rendered Carter unconscious. His consciousness became ensnared by the essence of the evil counterpart of Havok from the Mutant X universe, but Carter and the real Alex were rescued by Professor X. After the rescue, the Professor indicates he wants to talk to Annie about Carter's father, whose identity has yet to be revealed.

Annie later took him away from the Xavier Institute when she found it a too dangerous place for him. During their exit from the facilities, the new Brotherhood of Evil Mutants led by the ex-Acolyte Exodus, attack the Institute. One of the Brotherhood's many victims is Sammy. Carter telepathically detects Sammy's brutal death.

Also, while they leave, the Astral projection of an undetermined person is shown next to Carter's face. Annie seems unaware of this projection. Carter's dialogue and expression at this time hint that he is under the control of this individual. The projection was later revealed by Austen as the intended return of Cassandra Nova, but on his departure from the books, the storyline was dropped.

Carter Ghazikhanian is a mutant who possesses both telepathic and telekinetic abilities. The full extent of Carter's powers, however, are still undetermined.

Other versions of Carter Ghazikhanian
In X-Men: The End Carter is depicted as a deeply traumatized child, possibly as a result of the deaths of both his mother and Havok. His powers have evolved to the point of being able to create solid psionic constructs, as he is seen playing in a castle he created. He is killed, along with most of the student body, when Skrulls invade the mansion.

Ghost Girl
Ghost Girl is an alias used by multiple superheroes in the Marvel Universe.

Ghost Girl ll (Lili Stephens)
Ghost Girl (Lili Stephens) is a fictional mutant superhero in the Marvel Universe. She was created by Steve Seagle & Scott Clark, and first appeared in Alpha Flight vol. 2 #2.

Ghost Girl is a former member of the superhero team Alpha Flight. Department H call her a "Legacy" case, but they never explained what that means. She possesses the ability to "phase" or literally pass through solid matter by passing her atoms through the spaces between the atoms of the object through which she is moving. Being intangible she becomes invulnerable to physical attacks. It's unknown if she has the skill with phasing as Shadowcat does. Her powers were never explained; it may be assumed she uses the same process Shadowcat does.

Ghost Girl can also use her intangible body to create gateways through solid objects for others to use. She has created pathways for Puck and Flex to pass through her, and doing so tickles her.

Goblyn
Goblyn (Goblyn Dean) is a fictional mutant character in the Marvel Comics universe. She first appeared in Alpha Flight #48 (July 1987), and was created by Bill Mantlo and Terry Shoemaker.

The character subsequently appears in Alpha Flight #53–62 (December 1987–September 1988), #64-71 (November 1988–June 1989), #82 (March 1990), #109–112 (June–September 1992), and #120 (May 1993).

One of a pair of fraternal twins, before birth, it was revealed that Goblyn was a mutant and would be of monstrous appearance. Her parents decided that for her own good she would be aborted. Sensing the danger, her sister Laura (later known as Pathway) used her own mutant ability to send Goblyn to another dimension where she would be safe. Later Laura would return her to Earth, where they would both become involved with Alpha Flight.

Goblyn received an entry in the Official Handbook of the Marvel Universe Update '89 #3.

Snarkle enters their dimension with the intent of having their revenge, but Gordon chooses to stay declaring "Goodbye Snarkle. I never liked you", leaving Snarkle to be comically defeated by the younger Inhumans.

Greystone
Devlin Greystone is a fictional Māori character in the Marvel Universe, who was part of the second incarnation of X-Factor. He was created by Howard Mackie, and first appeared in X-Factor #140.

Greystone is from the same alternate future as Bishop, Archer, Fixx, and Shard. He is a member of the Xavier Underground Enforcers (XUE), a rogue branch of the Xavier's Security Enforcers (XSE) who wanted to travel back in time and change their future.

When he was a child, Greystone lived with his mother in a type of mutant concentration camp. As part of their punishment, each prisoner was required to have an "M" branded over their right eye to outwardly signify their status as a mutant. During his branding process by an evil man named Micah, Greystone panicked and—due to the large amount of stress—manifested his mutant power years before the traditional onset at puberty. This resulted in him breaking the machine (leaving him with only a partial brand), and trying to break out with his mother. Micah shot and killed her and was about to kill Greystone too if not for the incitement of the Summers Rebellion which ultimately led to mutant freedom. However, this was not as grand as it seemed, for Greystone became an orphan and a street urchin outside the confines of the camp.

Upon discovering that Shard was in the present, the X.U.E. managed to travel back in time due to the psionic link Fixx created between the members of the X.U.E. which Shard was also a member of, and inhabited the bodies of three recently deceased people. Greystone inhabited the body of the adolescent teen Brian Young.

While looking in the newspaper one day, Greystone happens to see the picture of a young boy named Micah. He immediately recognizes him as the same Micah who murdered his mother and concocts a plan to murder the child, thus averting his future and his mother's death. He, along with Fixx and Archer, track down the boy and Greystone tries to kill him. Archer and Fixx convince him that it is unethical to condemn the child for crimes he has not yet committed and the trio leaves. They had tried to change the future but instead ended up joining X-Factor.

Greystone slowly developed temporal insanity, believing that his mission was accomplished, and he could go home to a better world and be reunited with his mother, who might theoretically be alive. In an attempt to return to his own time, Greystone built a flying time machine, but due to shoddy craftmanship and unsound theories, the craft exploded, seemingly killing Greystone and Havok, who was attempting to stop him.

Greystone can increase his body mass, density, durability, stamina and strength exponentially but at a price: the bigger he gets, the more deformed and horrific-looking he becomes. Greystone can appear as his host body or in his original body—humorously a small, white child—also carrying the memories from both bodies.

Grotesk
Grotesk is a fictional character in the Marvel Universe. He first appeared in X-Men #41-42 (February–March 1968), and was created by Roy Thomas and Don Heck.

The character subsequently appears in Ms. Marvel #6 (June 1977) and #8 (August 1977), Avengers Annual #20 (1991), Avengers West Coast Annual #6 (1991), Iron Man Annual #12 (1991), and Thor #481 (December 1994).

Prince Gor-Tok, also known as Grotesk, is the former prince of a warlike, civilized race of Gortokian Subterraneans with human intelligence and virtually human appearance. Underground atomic explosions created by surface humans led to the extinction of the entire race except for Grotesk, who, his mind and body first distorted by radiation, vows to destroy the entire surface world.

Grotesk encounters the heroic mutants the X-Men on his first foray to the surface world. He fights them, and kills the Changeling (who, at the time was posing as Professor X to the X-Men).

Grotesk later encounters Ms. Marvel. He also sides with the Mole Man and Tyrannus in their war against the surface world and the Avengers.

Grotto
Grotto is a fictional character appearing in Marvel comics. He was created by Frank Miller and first appeared in Daredevil Vol. 1 #168.

Grotto is a small-time criminal and the frequent partner of Turk Barrett. Like Turk, he works for Eric Slaughter and the Kingpin, resulting in frequent encounters with Daredevil and at one point encountered Elektra. Although generally regarded as unintelligent, Grotto often tries to act as a voice of reason to Turk's aggressive and overconfident behavior such as refusing to escape prison so that they can fill out their time and return to the streets without problem. When the Kingpin returned to San Francisco, Grotto was rehired as one of his elite members.

Grotto in other media

 * Grotto, legal name Elliot Grote, appears in the second season of Daredevil, portrayed by McCaleb Burnett. He is a low-ranking member of the Kitchen Irish mob, serving as a driver and occasional assassin for their leader Nesbitt. After Frank Castle attacks a Kitchen Irish meeting, of which Grotto is the sole survivor, Grotto flees to Josie's Bar, coincidentally while Matt Murdock, Karen Page and Foggy Nelson are there. Matt, tipped off by Grotto's adrenaline spike and observing that he's carrying a weapon, approaches Grotto, who in turn asks the Nelson & Murdock trio to get him witness protection. While Karen guards Grotto as he recovers in the hospital from a shrapnel wound he received in the shooting, Frank shows up and makes a second attempt to kill him, but Karen manages to get Grotto out of the hospital and to the 15th Precinct. With Matt recuperating from getting shot in the head by Frank during the attack, Karen and Foggy are left to negotiate a plea deal for Grotto with District Attorney Smanatha Reyes and Assistant District Attorney Blake Tower. As part of the deal, Grotto will give up an associate in the mafia named Edgar Brass in exchange for witness protection. However, Reyes double-crosses Nelson & Murdock, instead using Grotto as bait for Frank, with "Brass" actually being an ESU officer. A firefight breaks out and Grotto flees the scene. He later calls Karen from a payphone to unceremoniously fire the firm, despite Karen's efforts to apologize for Reyes' double-cross. He does not get far, as Frank captures him and takes him to a rooftop where he has already captured and chained up Matt. Frank gives Matt a gun, and the choice of killing either one of them. Matt shoots the chains securing him, but is unable to stop Frank from fatally shooting Grotto. Out of guilt, Matt, Karen and Foggy hold a private funeral for Grotto at Matt's church. In his eulogy, the most positive thing Father Lantom can say about Grotto is that he went to and donated to the church, and he explains to Matt afterwards that if they ignored his criminal past, there would be no learning from it.
