Buffy the Vampire Slayer

Cordelia Chase is a fictional character created by Joss Whedon for the television series Buffy the Vampire Slayer; she also appeared on Buffy's spin-off series Angel. Portrayed by Charisma Carpenter, the character appears as a series regular in the first three seasons of Buffy, before exiting the show and becoming a series regular during the first four seasons of Angel. The character made her last television appearance in 2004, appearing as a special guest star in Angel's one hundredth episode. Cordelia also appears in apocryphal Buffy and Angel material such as comic books and novels.

Cordelia is introduced in "Welcome to the Hellmouth" as one of Sunnydale High's popular cheerleaders, attending school alongside vampire slayer Buffy Summers. Through her interactions with Buffy and her friends, she comes to accept the existence of supernatural forces and helps Buffy fight against them. In the television series Angel, Cordelia joins Angel, a heroic vampire with a soul, in forming a detective agency dedicated to stopping supernatural forces and helping the helpless. After Cordelia acquires the ability to see visions of those in need, she becomes a more compassionate and heroic character. In the fourth season of Angel, she appears to take on a villainous role before it is revealed that she is possessed by a malevolent deity; this storyline eventually leads to her death and subsequent exit from the series. The character makes further canonical appearances in the comic books Buffy Season Eight and Angel: After the Fall, in a dream flashback and as a spirit guide.

Created as a foil for Buffy's titular heroine, Cordelia was initially characterized as "shallow", "vain" and "self-centered", and was used in the series to create conflict for the other characters. The character went through changes as she gradually redeemed herself throughout the course of Buffy and Angel, and has received attention in academic texts related to gender studies and social status.
