Mandy

Being a model of the "popular teenager" stereotype (in her own opinion), she is shown to be stylish, charismatic, popular and pretty but is also bratty, materialistic, snobbish, egocentric, greedy, arrogant, cruel, naughty, abusive, and downright maleficent. 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. ("Computer Creep Much?", "Like, So Totally Not Spies")

When she fails to enrage an enemy, she becomes frustrated that the person is not showing envy or fear. ("Super Agent Much?", "Totally Icky!", "Trent Goes Wild")

Appearance: she is seen wearing a light purple and white long-sleeved dress, with her hair styled in a classic look and a black wig styled into Marie Antoinette ringlets.

Mandy is a high school bully who wants to have sex with you. And she is not going to stop until she gets what she wants.
