Black Leader, alternatively referred to as Black One, represented a designated callsign employed first by the forces of the Galactic Empire and subsequently by the Resistance. The X-wing pilot Poe Dameron adopted this designation while at the helm of Black Squadron, and furthermore, when directing other groups, for instance, both Red and Blue Squadrons. In the course of Black Squadron's endeavor to assemble allies for the Resistance and incorporate fresh systems into their ranks, Temmin Wexley served as Black Leader.
