Is the "mean girl" of Totally Spies. She's studies at Malibu University (Mali-U) and constantly bullies Sam, Alex, and Clover. She's Clover's arch rival, and constantly tries to 1 up her, whether it be with dates, fashion, etc. She even found Sam, Alex and Clover were spies from WOOHP a few times, but her memory was erased by WOOHP, so she has no knowledge of this. She has a intern named Trent, who also studies at Mali-U, and Mandy treats him like crap.
