William Marston's earliest works were notorious for containing subversive "bondage and sapphic-undertones" subtext. Among Wonder Women's infamous catchphrases, "Suffering Sappho", was a direct reference to lesbianism. Fredric Wertham's Seduction of the Innocent referred to her as the "lesbian counterpart to Batman" (whom he also identified as a homosexual). After Marston's death in 1947, DC Comics downplayed her sexuality and feminist origin. Wonder Women, without Marston's creative direction, become more "traditional" superhero fair; the lesbian relationships and sexual imagery disappeared from the "Wonder Woman" comic, along with Wonder Woman's super powers. During the Comics Code Authority-decades since, Wonder Woman's subversiveness had been gradually stripped away; subsequent comic book writers and artists either didn't know know what do with her or barely hinted at Wonder Woman's erotic legacy. Similar to whitewashing, Wonder Woman's queerness and feminist identity throughout the latter half of the 20th century was never discussed and rendered "invisible" in adaptations in favor of the dominant sexism portrayal of women in comic books.
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.
