Venom Zero—also known as "VZ"—was a squad of Venom assault troopers that served the Galactic Alliance Core Fleet during the Second Imperial Civil War. Considered to be an elite unit, Venom Zero was not permanently assigned to any one Sabertooth-class assault/rescue vessel like its fellow squads but was constantly transferred between ships when the mission deemed that the unit was needed. Like other Venom assault squads, Venom Zero was trained in close-quarters combat, zero-G combat, and ship-to-ship boarding tactics. When not engaged in battle, Venom Zero was responsible for training its fellow squads in advanced combat techniques.
