Wonder Woman has been the subject of a discussion regarding the appearance and representation of female power in general, and of female action heroes in particular since her initial 1941 appearance in Sensation Comics, as she was created to document "the growth in the power of women", while wearing "a golden tiara, a red bustier, blue underpants and knee-high, red leather boots." She was blacklisted a year later in 1942 in the "Publications Disapproved for Youth" because, the group behind the list argued, she was "not sufficiently dressed".
Wonder Woman's sexual and bondage themes in her earliest days were not without purpose, however. Her creator, William Moulton Marston, theorized that human relationships could be broken down into dominance, submission, inducement and compliance roles which were embedded into our psyche. Because males were, more often than not, dominant in societies, Marston believed that "Women as a sex, are many times better equipped to assume emotional leadership than are males."  Marston wanted to convey his progressive ideals, through his use of bondage imagery, that women are not only capable of leadership roles, but should be in charge of society. Although Marston had good intentions with these themes, in Wonder Woman's early appearances, the bondage elements were controversial, as they were often seen to overly fetishize women in power rather than promote such women. Noah Berlatsky criticized this imagery in Wonder Woman's earliest days noting that "the comics take sensual pleasure in women’s disempowerment."  Despite having the mixed messages of this imagery, Marston fiercely believed that women would soon rule the earth and meant to showcase his predictions through sexual themes in his stories. He was an open feminist while studying at Harvard where he once said "Girls are also human beings, a point often overlooked!"
