Sackhoff was announced as a guest star on The Flash Season Four back in August. Black, also known as Blacksmith, runs a black market for supervillains and "uses every means possible, including the long list of metahumans under her thumb, to ensure her illicit enterprise thrives."
While Sackhoff is best known for playing hotshot pilot Kara "Starbuck" Thrace on Syfy's reboot of Battlestar Galactica, she has also appeared on Longmire and 24.
Sackhoff is just the latest Battlestar Galactica alum to join the Arrowverse. Aaron Douglas, who played Chief Galen Tyrol on Battlestar Galactica, played the villain Turtle on The Flash. Fellow Battlestar Galactica stars Tahmoh Penikett, James Callis, and Rekha Sharma have made appearances on Arrow.
In "Girl's Night Out," having received an ominous threat from her old boss, Amunet (guest star Katee Sackhoff), Caitlin (Danielle Panabaker) fears that her past time as Killer Frost may be back to haunt her.
Felicity (guest star Emily Bett Rickards) comes to Central City to help the girls celebrate Iris's (Candice Patton) bachelorette party, while Cisco (Carlos Valdes), Joe (Jesse L. Martin) and the guys take Barry out for a night on the town.
Laura Belsey directed the episode, written by Lauren Certo & Kristen Kim.
The Flash airs Tuesdays at 8 p.m. ET on The CW.
