Mandy is the so-called "mean girl" of Totally Spies! and Clover's arch-nemesis and rival. She is one of the most popular girls at Beverly Hills High and thinks highly of herself. She apparently may have inherited these negative traits from her mother, Phoebe. Her father is never seen, but he's mentioned in the series (and it is also implied that her parents are in fact married). Mandy has a high, squeaky voice with a nasal laugh in the original version while in the Japanese dub, she has a less squeaky voice than the original version. However, Mandy does actually have a nicer side to her personality, but whenever she becomes nice to people, it never lasts long and she goes back to being mean and selfish if she is provoked in one way or another. Mandy shows her belief that she is the best at "everything" shown in the "Black Widows" prior the Spelling Bee and in "Sis-KaBOOM-Bah!". The reason for this is most likely her need for attention and wanting to feel important. Mandy derives pleasure from enraging people. When she fails to enrage an enemy, she becomes frustrated that the person is not showing envy or fear. Mandy is a Caucasian girl with long black hair, violet eyes, a beauty mark under her left eye, and fair skin. Her primary outfit is a red dress under a white long sleeve button shirt and white boots. Her primary outfit is been slightly altered like Clover's primary outfit. She also wears purple lipstick. Mandy sometimes has her hair tied in a high ponytail with a light blue scrunchie.
