Earth-Two Giganta was introduced as a foe of
DC Comics character
Wonder Woman during the
Golden Age of Comic Books. In the story, a scientist named Professor Zool artificially mutates a
gorilla named Giganta into a malicious red-haired strongwoman. The mutation machine goes haywire and somehow reverts the world to an earlier stage. Giganta joins a primitive tribe to attack Wonder Woman, but is defeated. When the world gets to the
Golden Age of humanity, Giganta causes trouble by encouraging a rebellion, which Wonder Woman stops. When the world returns to normal, Giganta is still in her "strongwoman" form. Giganta is ultimately subdued and captured by Wonder Woman and taken to Themiscyra for rehabilitation. Giganta joins a rebellion of prisoners held on the island started by the Saturnian slaver
Eviless, thereby becoming a member of the criminal team
Villainy Inc. Eviless steals Wonder Woman's lasso and kidnaps Hippolyta. Giganta joins with the Atlantean
Queen Clea to cause trouble.
Earth-One In 1966, Giganta's origin is revamped to include
Doctor Psycho. In this story, Doctor Psycho hypnotized a zoo gorilla named Giganta to fall in love with
Steve Trevor. After
Wonder Woman defeats Giganta, Professor Zool appeared asking to have the gorilla turned over to her for experimentation. Taking advantage of this, Doctor Psycho took Giganta out of the zoo and brought her to Zool so that he can use an evolution ray on her. This turned Giganta into a huge blonde woman who still loves Steve Trevor. Wonder Woman defeated Giganta and took her to Paradise Island for rehabilitation.
Doris Zeul The contemporary version of the character is the alter-ego of Doris Zeul, who suffers from a fatal blood disease. She captures Wonder Woman and plans to put her "life-essence" into Wonder Woman's body using an experimental machine. Interrupted by
Wonder Girl halfway through the experiment she ends up with her consciousness in a test animal gorilla named Giganta. through unknown means (though Olga was comatose due to a mysterious
shaman) and uses the machine to successfully transfer her mind into that body, keeping the villain name "Giganta". Following her transformation, Giganta allies herself with
Queen Clea and
Villainy Inc. in an attempt to conquer the
lost world of
Skartaris. Villainy Inc. is defeated by Wonder Woman, but Giganta is subsequently seen as a member of several criminal groups, including the
Secret Society of Super Villains. As part of the Society, she takes part in the "Battle of Metropolis", a confrontation with multiple heroes, including
Elasti-Girl, the size-changing member of the
Doom Patrol. The Society ultimately loses this battle. When Diana Prince noted that Giganta's intellect reduces as she grows in size, compelling the villain to become less rational and more prone to violence, she was corrected by her colleagues in the
Department of Metahuman Affairs. They implied that Giganta has overcome that limitation and retains her full intelligence at any size. "
One Year Later," Giganta, along with
Cheetah and Doctor Psycho, engage in a battle with
Donna Troy (who has assumed the identity of Wonder Woman one year after the events of
Infinite Crisis), as part of a search for, as they term it, the "real" Wonder Woman (Diana). Giganta is a teacher at
Ryan Choi's Ivy Town University. Infected and controlled by
M'Nagalah, the monstrous
Cancer god, she was sent to seduce and capture Ryan Choi, the new Atom, in the process even going so far as to swallow the miniature hero alive (he escapes, and also discovers that she has a tongue piercing). Now free of M'Nagalah's control, a seemingly repentant Dr. Zeul retains her position at Ivy University and has approached Ryan for a second chance, despite the bizarre circumstances of their first meeting. Before their second date, the Atom is approached by Wonder Woman on behalf of the Department of Metahuman Affairs and asked to wear a wire on his date with Dr. Zeul. After professing her desire to reform, she is informed that Ryan is wearing a wire and tears off the roof of the restaurant to see Wonder Woman and Ryan talking - unaware that Ryan had removed the wire. A fight between Wonder Woman and Giganta ensues. Wonder Woman quickly knocks Giganta out but Ryan intervenes to stop Wonder Woman from beating her further, after admitting she had lost her temper - they realize that Dr. Zeul has disappeared. Whether she heard or saw Ryan's actions to stop her from getting further injuries is yet to be seen. Giganta is a member of the new
Injustice League and she is one of the villains featured in the
Salvation Run. Over the course of the series she fights as one of the new incarnations of the
Female Furies with
Wonder Woman,
Batwoman, and
Catwoman. She is possessed by the spirit of the fury
Stompa, and only freed when
Supergirl smashes the skull-and-crossbones mask from her face. Giganta is attacked by Diana while on her way to a date with Ryan Choi, implying that their relationship has survived despite earlier difficulties. Mellower than in her appearances in the
All-New Atom series, she seems to accept and respect the shortcomings brought by their different lifestyles, going so far as to help Wonder Woman in a mission, reasoning that, with Ryan being a superhero, they should both be used to putting their heroics in front of their private lives.
Bane later recruits Giganta into the Secret Six. The team also includes the shrinking killer,
Dwarfstar, who had hired
Deathstroke and his
Titans to kill Ryan Choi. Giganta initially seems unaware of this fact, admitting to Dwarfstar that she is dating the Atom (much to Dwarfstar's amusement). Following a disastrous mission to
Skartaris,
Amanda Waller reveals the details of Ryan's murder to Giganta. After luring Dwarfstar to her bedroom with the promise of sex, Giganta strips him of his belt (the source of his powers) and beats him into submission. She is last heard covering Dwarfstar's mouth with duct tape to stifle his screams, telling him that she plans on keeping him alive so that she can prolong his suffering. In September 2011, DC Comics revised the fictional history of its comic book line under the title "
The New 52". In the revised comic book line, Doris Zeul gained her abilities from radiation treatment intended to treat a rare blood disease. Giganta appears as a member of the Secret Society during the "
Trinity War" storyline. She assists
Vandal Savage and
Signalman into tracking
Pandora. When the three villains attack Pandora, Pandora successfully subdues Giganta. Her costume combines elements from her original and
One Year Later costumes. After her first encounter with Pandora, Giganta returns for revenge following the conclusion of the
Forever Evil storyline. During their fight, Pandora looks into Giganta's soul, and reveals her origin story. Doris Zeul was a bullied child with a blood disease, but cured herself with a radical procedure that gave her her growth powers. A side-effect of the untested operation was that it reduced her intellect. After the events of "
DC Rebirth," Giganta appeared alongside several other villains as they battled the
Justice League. Later, Wonder Woman and Steve Trevor tracked Giganta down to a Los Angeles museum. Giganta had been stealing mystical artifacts for unknown reasons. Wonder Woman managed to defeat the giantess. She was then taken into custody. When Steve Trevor interrogated Giganta in
Belle Reve alongside Amanda Waller, he discovered that Giganta had been recruited by Darkseid to steal the artifacts. She told Steve Trevor where to find the remaining artifacts. She stated that she, Steve, and Wonder Woman have had a long history together. Amanda Waller later recruits Giganta into
Task Force XL to capture
Damage. During the battle, Giganta revealed that she would love to study Damage's physiology. However, Damage bursts through Giganta's hand, leaving her to bandage herself while the rest of the team battle him. In
Doomsday Clock, Giganta is among the villains who meet with the
Riddler to discuss the Superman Theory. Later, she participates in the attack led by
Black Adam against the United Nations, where she is beaten by Wonder Woman. When the Sovereign conspires to turn the world against Wonder Woman and the Amazons,
Sarge Steel recruits Giganta and several other villains to kill Wonder Woman. ==Powers, abilities, and equipment==
