Wonder Woman, Harley Quinn, Shuri, and Black Widow. These four characters portray very different versions of women: the superheroine, the abuse victim, the fourth wave princess, and the spy, respectively. In this in-depth analysis of female characters in superhero media, the author begins by identifying ten eras of superhero media defined by the way they portray women. Following this, the various archetypes of superheroines are classified into four categories: boundary crossers, good girls, outcasts, and those that reclaim power. From Golden Age comics through today's hottest films, heroines have been surprisingly assertive, diverse, and remarkable in this celebration of all the archetypes.
