Sword Mastery: Wonder Woman is an extremely skilled swordswoman, with centuries of experience wielding her magical God Killer sword (and later the Sword of Athena) in many battles, including those of World War I. Thus, she managed to slash at enemy soldiers with her sword even while racing past on horseback, to instantly slice apart in mid-air a car hurled at her by Doomsday with the Sword of Athena, to later do the same to massive piece of debris hurled at her by resurrected Superman, and to sever one of Doomsday's arms during her battle with the monster, delivering wounds that would have otherwise been lethal, had it not been for the monster's incredible healing factor and adaptive evolution.
Marston introduced the idea to Gaines. Given the go-ahead, Marston developed Wonder Woman, whom he believed to be a model of that era's unconventional, liberated woman. Marston also drew inspiration from the bracelets worn by Olive Byrne, who lived with the couple in a polyamorous relationship. Wonder Woman debuted in All Star Comics #8 (cover date Dec/Jan 1941/1942, released in October 1941), scripted by Marston.
In the wake of the 1954 hearings, DC Comics removed Bender from its editorial advisory board, and the Comics Magazine Association of America adopted a new code. Under its terms, comic books could contain nothing cruel: “All scenes of horror, excessive bloodshed, gory or gruesome crimes, depravity, lust, sadism, masochism shall not be permitted.” There could be nothing kinky: “Illicit sex relations are neither to be hinted at nor portrayed. Violent love scenes as well as sexual abnormalities are unacceptable.” And there could be nothing unconventional: “The treatment of love-romance stories shall emphasize the value of the home and the sanctity of marriage.”
Marston was an outspoken feminist, swinger, and firm believer in the superiority of women. He described bondage and submission as a "respectable and noble practice". Marston wrote in a weakness for Wonder Woman, which was attached to a fictional stipulation that he dubbed "Aphrodite's Law", that made the chaining of her "Bracelets of Submission" together by a man take away her Amazonian super strength.
The Diana Prince alias also played an important role after the events of Infinite Crisis. Wonder Woman was broadcast worldwide killing a villain named Maxwell Lord, as he was mind controlling Superman into killing Batman. When Wonder Woman caught him in her lasso, demanding to know how to stop Superman, Maxwell revealed that the only way to stop him was to kill Lord, so as a last resort Diana snapped his neck. To recover from the trauma of killing another person, the Amazon went into a self-imposed exile for one year. On her return to public life, Diana realized that her life as a full-time celebrity superhero and ambassador had kept her removed from humanity. Because of this she assumed the persona of Diana Prince and became an agent at the Department of Metahuman Affairs. During a later battle with the witch Circe, a spell was placed on Diana leaving her powerless when not in the guise of Wonder Woman.
