Khan Doorman, father of Uzi Doorman, the estranged husband of Nori Doorman (who he believes is dead) and the inventor of the blast doors that kept his colony safe used to be the leader of the Worker Defense Force, an organization meant to protect Worker Drones from the Disassembly Drones (despite being completely incompetent and cowardly while preferring to do nothing but play cards behind the blast doors for protection) until he drank oil under temptation and turned into a Disassembly Drone.
