Mindy

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. Mandy is the main antagonist for the girls when they are not on spy missions.

Mandy's rivalry with Clover is the most pronounced. They often compete over boys, popularity contests, bragging rights, the latest fashions, and virtually everything else. Mandy will go out of her way to annoy the girls and get them in trouble, and will even use dishonest means in order to do it.

In Season 1 - Season 4, Mandy is often accompanied by her two BFFs/yes-women Caitlin (Alex's rival) and Dominique (Sam's rival). However, it wasn't until Season 4 that there was actually any loyalty between the three. Before then, they had each been shown to leave the others at the drop of a dime. At the start of Season 5, Mandy and her crew apparently went their separate ways after graduating from Beverly Hills High. While Mandy was supposed to attend a ski school in Aspen, she transferred to Malibu to attend Malibu University with her cousin Mindy. Mandy and Mindy, known by the girls as the Terror Twins (though they are only called that in "Evil Sorority"), are seen together for most of the fifth season, save for the finale.

In the episode "Evil Coffee Shop Much?", she follows the girls to WOOHP and her attitude impresses Jerry, who makes her a WOOHP spy.
