9. Cordelia Chase, Buffy the Vampire Slayer
The OG of mean girls in vampire shows, Cordelia was a serious meanie who was skilled at using someone’s insecurities against them. She shoots jabs at everyone and embodies the popular girl, using her good looks and social standing to ensure everyone knows she’s the queen bee. Throughout the show, however, this evil cheerleader learned how to become a better person, but she was still just as blunt as she was on day one.
