CF-9164 was a female stormtrooper of the First Order. She had trained under Captain Cardinal, who later defected from the First Order and took his former name of Archex. CF-9164 was deployed to Black Spire Outpost on Batuu under Lieutenant Wulfgar Kath, and guarded the captured Resistance spy Vi Moradi. Archex arrived to rescue Moradi, and briefly fought with CF-9164, who was then shot and killed by Zade Kalliday.
