Silver Swan
The Silver Swan is a fictional character that frequently appears in DC Comics publications and related media as a regular foe of Wonder Woman. She initially appeared in 1982 in Wonder Woman (vol. 1) issue 288, written by Roy Thomas and drawn by Gene Colan, with the superhuman power to emit a terrible sonic wail. As comic book continuities have developed and shifted since then, the character has had various updates.
Helen Alexandros, the first Silver Swan, debuted in Wonder Woman (vol. 2) issue 15 in 1988, Valerie Beaudry, the second Silver Swan, debuted in Wonder Woman (vol. 2) issue 15 in 1989, and Vanessa Kapatelis, the third and current Silver Swan, debuted in 2001 in Wonder Woman (vol. 2) issue 171. All three characters' backstories are based on Hans Christian Andersen's fairy tale The Ugly Duckling: Alexandros, Beaudry, and Kapetelis all believe they are undesirable, unattractive, or unwanted in various ways, only to be transformed into extraordinarily beautiful (and vengeful) super-powered women.
