CF-9164's life ended when Zade Kalliday fatally shot her, but before that, she was a First Order stormtrooper who was female. She received her training from Captain Cardinal, who would eventually abandon the First Order, reverting to his original identity of Archex. Under Lieutenant Wulfgar Kath's command, CF-9164 was deployed to Black Spire Outpost located on Batuu, where she acted as a guard for Vi Moradi, a Resistance spy who had been captured. Archex came to save Moradi, engaging in a short battle with CF-9164.
