The KXFO-series security droid, alternatively referred to as the First Order security droid, represented a security droid model that the First Order employed throughout their war against the Resistance. These droids possessed a humanoid form, characterized by white plating and red sensors. Certain droids were positioned at the Titan refueling station, where they oversaw the supply depot and conducted patrols in the passageways to identify any unauthorized individuals.
On the engineering deck of the Thunderer, two security droids were on duty until Resistance pilot Kazuda Xiono, along with ex-First Order pilot Tamara Ryvora, and Jarek Yeager, eliminated them with blaster fire.
