Emma Caulfield's Cameron Chase Comes to Supergirl on January 18

CBS has amended the episode synopsis released earlier this week and revealed that DEO Agent Cameron Chase will make her first appearance on January 18th's episode, titled "Childish Things."

Chase, who first appeared in Detective Comics, went on to star in her own short-lived comic book series and then appeared in Marc Andreyko's fan-favorite run on Manhunter.

WB's official description of the character on the show says this FBI agent has "little sympathy." The full description reads, "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, J'Onn J'Onzz -- as The Bronze Wraith -- was a member of a '70s superhero team called The Justice Experience, in which Chase's father Acro-Bat was a member before his death. J'Onn, of course, was recently introduced to Supergirl viewers, and has been on the show all along, using his shapeshifting abilities to impersonate Hank Henshaw.

Emma Caulfield, best known for her role as Anya Jenkins on the television series Buffy the Vampire Slayer, will play Chase as previously announced, but it wasn't known until now in which episode she would first appear.

Kara does her best to support Winn when his father, the supervillain Toyman, breaks out of prison and seeks out his son for unknown reasons. Also, Cat offers Lucy a job at CatCo and Alex asks Hank to use his powers to help uncover Maxwell Lord's plans, on SUPERGIRL, Monday, Jan. 18 (8:00-9:00 PM, ET/PT) on the CBS Television Network. Henry Czerny guest stars as Winslow Schott, Sr., aka Toyman.

Supergirl returns from its hiatus on January 4.
