Femme Fatale is a recurring antagonist in the 1998 Powerpuff Girls series, making her debut in the Season 3 episode "Equal Fights". She's a bank robber and master thief with a particular agenda: she exclusively steals Susan B. Anthony coins, asserting that all other currency features men. While she brands herself as a champion of women's rights, her actions often contradict her supposed feminist ideals. She's earned monikers like the "Queen of Corruption," the "Mistress of Misdeeds," and the "Dame of Disaster."

== Appearance == Femme Fatale is depicted as a tall (5'8" or 173 cm), fair-skinned woman with an hourglass figure, weighing approximately 135 lbs (61 kg). She has long, straight blonde hair and wears red lipstick. Her blue eyes are typically hidden behind a distinctive blue eye mask that resembles the upper part of the female symbol (♀). This design is completed by a matching blue print on her full white bell-bottom jumpsuit, which forms the lower part of the female symbol. She completes her look with white, heeled ankle boots.

== Personality == Despite her self-proclaimed status as a "master thief" and a proponent of feminist ideals, Femme Fatale is largely a hypocrite. She rationalizes her crimes by superficially invoking feminist arguments, despite demonstrating a lack of basic knowledge about historical figures like Susan B. Anthony. In "Equal Fights," she manipulates Blossom, Bubbles, and Buttercup into believing her actions are a form of rebellion against "feminine injustice," allowing her to continue her bank robberies.

Her misandry is evident in her exclusive pursuit of Susan B. Anthony coins, but her actions often undermine her supposed principles. She has been shown stealing from a female bank president, injuring a policewoman, and even copying a teenage girl's hairstyle. Furthermore, she exhibits a dismissive attitude toward other female villains like Princess Morbucks ("that little brat") and Sedusa ("the chick in the underwear"), despite their demonstrably greater capabilities.

At the end of "Equal Fights," her charade crumbles when the Powerpuff Girls reveal the truth about Susan B. Anthony. She's promptly defeated and imprisoned, complaining about how horizontal prison stripes make her look "fat."

== Abilities == Femme Fatale's claims of being a "Master Thief" are largely unfounded. She possesses no extraordinary skills or superhuman abilities beyond being a brazen bank robber and a persuasive orator. Her typical method of robbery involves threatening others with a weapon shaped like the female symbol (♀) she is never actually seen firing.

== Trivia ==

• The name "Femme Fatale" is French for "fatal woman" and is a common stock character in film noir, often portraying a mysterious and seductive woman who brings disaster to men.
• When not in costume (as seen at the end of "Equal Fights"), Femme Fatale bears a strong resemblance to the teenage girl whose hairstyle she copied, albeit without braces or freckles.
• During her appearance, Femme Fatale raises a point about the perceived disparity in popularity and reverence between male and female superheroes, noting how many heroines are often extensions of their male counterparts (e.g., Supergirl to Superman, Batgirl to Batman). However, numerous independent female superheroes exist beyond Wonder Woman, such as Starfire and Raven from Teen Titans.
• The underlying reasons for Femme Fatale's misandry are never explicitly explained in the series. While fan theories suggest experiences with misogyny or domestic violence, her hypocritical behavior complicates these interpretations.
• Femme Fatale also observes that villainy, like heroism, appears to be male-dominated. However, the Powerpuff Girls universe features many female supervillains, even if only a few are recurring characters.
• A character visually similar to Femme Fatale appears as a donut shop clerk in the episode "Cop Out."
• The symbols on her outfit and weapon are based on the female gender symbol (♀), which is associated with Venus, the Roman goddess of love and beauty, and the female sex.
• Manboy, a villain from the 2016 Powerpuff Girls reboot series, is loosely based on Femme Fatale.
