Dominique is one of Mandy's lackeys/best friends, along with Caitlin. She has short, dark red hair in style similar to Alex's hair, blue eyes and peach skin. Both she and Caitlin were written out of the series after "Evil Graduation" of Season 5, and were replaced by Mandy's cousin, Mindy, as they are probably attending colleges far from Malibu University.
She speaks with a valley girl accent, similar to Clover, and she is also obsessed with fashion and celebrities. However, Dominique is Samantha's rival instead. She has worn 2 Catsuits in the series: cyan ("Evil Jerry") as part of the "Spy Chic" trend, and purple ("Totally Busted") when she was a spy-ssassin.
Dominique and Caitlin seem to be Mandy's closest, or either, her only friends, because whenever Mandy's not with either one or both of them, she doesn't seem to hang out with anyone else. In fact, Dominique and Caitlin seem closer to each other than they do to Mandy.
- The first time Caitlin and Dominique were referred to directly by name in the regular series was in the season 4 finale "Totally Busted". There, Dominique attacks Sam in her bedroom as a spy-ssassin. Prior to that they were called Caitlin and Dominique in "Sis-KaBOOM-Bah!" but it was not made clear who was who.
