The chief chemist associated with General Ludendorff who specializes in chemistry and poisons. On her role, Anaya said, "Well, it was a small role in this big ensemble, but it is an important character in the story. I'm going to be a big nightmare" for Wonder Woman and Steve Trevor. Describing her character, Anaya said, "Dr. Maru loves rage and enjoys people's pain. She's creating terrible weapons, and her purpose in life is to kill as many people as possible, and provoke as much pain as possible". She researched World War I and Fritz Haber, the scientist who created mustard gas, to prepare for the role. On the character's facial scars, Anaya stated, "I went to Patty Jenkins and asked, 'What happened to her?' And she said, 'She did it on purpose.' I was like, 'What? Patty, you're going further than I ever imagined.' She said, 'She wants to provoke painful suffering, so she tested her own gas on her own face. She wanted to know how deep this form of her gas would go, so she put it on her own face.' You can see half of her face is completely gone. This is the sadistic side of Dr. Maru". She also stated her character "is quite the opposite to the lead role of this movie, one of the strongest characters ever of DC comics, Wonder Woman. I can tell you that Doctor Poison is someone with a capacity to provoke so much pain." On Dr. Maru's relationship with General Ludendorff, Anaya said, "I think that they have a relationship based on loyalty. Ludendorff is a very tormented General that lacks self-confidence. That's why, in part, he takes these drugs that Dr. Poison gives him. They are from different worlds, but they complement each other".
In 1954, Dr. Fredric Wertham alleged that there were lesbian subtexts to Wonder Woman and claimed comics contributed to juvenile delinquency in his book Seduction of the Innocent where despite a very obvious heterosexual relationship with Steve Trevor, Wertham asserted that Wonder Woman’s association with the Holliday Girls could be interpreted as a lesbian relationship. The Comics Code Authority was then introduced in reaction to Wertham 's claims against the entire industry.
That hardly ended the controversy. In February 1943, Josette Frank, an expert on children’s literature, a leader of the Child Study Association and a member of Gaines’ advisory board, sent Gaines a letter, telling him that while she’d never been a fan of Wonder Woman, she felt she now had to speak out about its “sadistic bits showing women chained, tortured, etc.” She had a point. In episode after episode, Wonder Woman is chained, bound, gagged, lassoed, tied, fettered and manacled. “Great girdle of Aphrodite!” she cries at one point. “Am I tired of being tied up!”
Seeking answers, Wonder Woman sought out an old friend that she believed could provide the way to Themyscira: Barbara Minerva, the Cheetah. Cheetah agreed to help, under the condition that Diana kill the plant-god Urzkartaga and free Barbara from her curse, which Diana agreed to do. When she located Urzkartaga, however, she discovered Steve Trevor and some of his fellow soldiers had been captured by Colonel Andres Cadulo, who intended to become the embodiment of the god and sacrifice Steve in the process. Wonder Woman freed dozens of Cadulo's captives and, with the help of Cheetah and the women he had captured, succeeded in destroying Urzkartaga and freeing Barbara from the curse of the Cheetah. With Barbara's help, Diana and Steve were able to find "Themyscira", though Diana was surprised to find her mother alive and well despite remembering her as dead at the hands of Hera. After removing her bracelets Diana realized that her past interactions with these representations of the Amazons and her home were in fact an illusion, and that she may have never returned home since she originally left to escort Steve to the United States. Upon this realization, Diana suffered a mental breakdown.
In 1911, when Marston was a freshman at Harvard, the British suffragist Emmeline Pankhurst, who’d chained herself to the gates outside 10 Downing Street, came to speak on campus. When Sanger faced charges of obscenity for explaining birth control in a magazine she founded called the Woman Rebel, a petition sent to President Woodrow Wilson on her behalf read, “While men stand proudly and face the sun, boasting that they have quenched the wickedness of slavery, what chains of slavery are, have been or ever could be so intimate a horror as the shackles on every limb—on every thought—on the very soul of an unwilling pregnant woman?” American suffragists threatened to chain themselves to the gates outside the White House. In 1916, in Chicago, women representing the states where women had still not gained the right to vote marched in chains.
It was later retconned by Gail Simone that Wonder Woman's outfit design had Amazonian roots. During a flashback in Vol. 3, Hippolyta is shown issuing orders to have a garment created for Diana, taking inspiration from the skies on the night Diana was born; a red hunter's moon and a field of stars against deep blue, and the eagle breastplate being a symbol of Athena's avian representations.[volume & issue needed]
