According to The Mary Sue's description, "After her father's violent murder, Cameron Chase decided to dedicate her life to law enforcement. Now a stern, no holds barred FBI agent, Chase's weapons of choice are manipulation and manpower. With little sympathy, and plenty of suspicions, she pursues her targets with ruthless determination."
In the comics, Chase debuted in "Batman" #550 and soon led her own title "Chase" by Dan Curtis Johnson, J.H. Williams III and Mick Gray, where she joined the DEO following her father's murder. In New 52 continuity, she resurfaced in "Batwoman" #1 and investigated Kate Kane for suspected terrorist activities on the DEO's behalf. In addition to her skills as an investigator and computer hacker, she has the subconscious ability to dampen Metahuman powers when she is threatened.
In addition to her role as Anya on "Buffy the Vampire Slayer," Caulfield has appeared as a series regular on "Life Unexpected" and "Gigantic."
"Supergirl" airs Mondays at 8 pm EST on CBS. Developed by producers Greg Berlanti, Ali Adler and Andrew Kreisberg, the series stars Melissa Benoist, Calista Flockhart, David Harewood and Chyler Leigh.
