The Galactic Golem is a solar-powered creature created by Lex Luthor who is an enemy of Superman.[1] 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".[2]

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

While testing it out, Flash sees that the loot of the villains that he fights goes missing.[4]

An amnesiac Gorilla Grodd in human form stumbles into Paul Gambi's shop. To help with Gorilla Grodd's amnesia, Paul Gambi starts to tell him the origins of the Rogues. Upon Flash's name triggering 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 Paul for stalling before taking Gorilla Grodd back to Gorilla City.[5]

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. What Paul didn't count on is that the Suit gained a mind of its own and could not be destroyed.[6]

In the "DC Rebirth" reboot, Flash invades the business of Paul Gambi to get information on where the Rogues are. He was unable to get an answer out of Paul.[7]

Allegra Garcia is a character appearing in American comic books published by DC Comics. She is the daughter of supervillain Eduardo Reyes / Wavelength, and inherited his light manipulation powers.[8][9]

Allegra Garcia was raised in the Santa Marta slums of Rio de Janeiro, Brazil by her foster parents Ramon and Esperanza Garcia. Upon emigrating to Gotham City while developing the ability to emit electromagnetic light, she fell in with some gangs and took parts in robberies before being stopped by the local vigilantes and remanded to Arkham Asylum. To reunite with his daughter after some villains he knew saw Allegra, Wavelength hired Deathstroke and his version of the Titans to spring her out of Arkham Asylum. Though they had to get through Batman and some of Arkham Asylum's inmates like Clayface, Killer Croc, Mad Hatter, Victor Zsasz who sought to take the advantage to escape from Arkham Asylum. 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. Deathstroke declined Allegra's offer to join up with him stating that she has a lot of growing up to do.[10]

After the Doom Patrol freed Mento from his mind-control, they fought Garguax. The Doom Patrol destroyed the ship which seemingly killed Garguax.[14]

Garguax later appeared as a member of the Brotherhood of Evil alongside General Immortus at the time when they unleashed a Giant Jukebox Robot.[15] 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.[16]

Garguax was with the Brotherhood of Evil at the time 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.[17]

Following the Doom Patrol's apparent death, Garguax creates a giant android called Mandred to attack Chief and Beast Boy.[18] When the Doom Patrol turns up alive as Brain tries to attack Chief, the Brotherhood of Evil get away as Brain remotely broadcasts some solar energy to revive Mandred.[19]

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.[20] The Doom Patrol and the Brotherhood of Evil had to work together to defeat Zarox-13.[21]

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.[22] 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.[23]

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)[25] and a distant relative to significant DC characters such as Aquaman, Ocean Master, and Zatanna through his brother's bloodline.

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.

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.[34][35] Unlike Lois Lane and Superman, Joan was always aware of the Flash's secret identity.[36] The events of Crisis on Infinite Earths retconned 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.[37][38]

Joan was described as an essential part of the Golden Age Flash's life in later decades by Mark Ginnochio of Comicbook.com.[39] Joan and Jay's marriage is cited as being "among the most popular of DC's earliest married characters" by Vaneta Rogers of Newsarama.[38] 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 weren't just lovers but also confidantes of their respective superheroes as depicted at the time.[40]

Gehenna is a superhero in the DC Universe. She is a clone of Victor Hewitt who is rescued by Firestorm.

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). In recent years, he apparently let go of his villainous ways marrying Amunet Black / Blacksmith. After serving his time, he moved to Keystone City and, following in his father's footsteps, became an honest Commissioner of Union 242. Over time, his elixir has slowly turned his skin into organic golden flesh.[51]

He was institutionalized after he disfigures a school bus driver who insulted him. After he is released, he commits a series of brutal murders while using a job through Leslie Thompkins to try and frame the Joker for his crimes, even revealing a plan to poison Gotham's youth through his hospice job with his "medication", reverse-engineered as a means to increase psychopathic tendencies. James Jr. nearly killed his mother and tortured his step-sister before he is apprehended by his father and Batman (Dick Grayson) and institutionalized in Arkham Asylum while the plan's success is ambiguous.[65]

In 2011, "The New 52" rebooted the DC universe. James Jr. appears in the Batgirl series. He escapes from Arkham and stalks his sister who he views as a rival for their father's affection.

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. His body is taken to a doctor named Doc Willard who transplants his brain into the body of a towering gorilla. When the body gains consciousness, George becomes Gorilla Boss. Due to the fact that the gorilla body doesn't 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.[69]

Superman and Batman were able to thwart the alien invasion, but Gorilla Boss escapes with Doc Willard.[70] 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.[71] 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.[72]
