HK-80 Commando Droids, or HK Assassin Droids, were old assassin droids that spoke in almost every language in the universe. They were developed by the Czerka Corporation, then by Duwani Mechanical Products, and then later by the Mandalorian Three Shipyards and Guardians of the Consortium. The HK-80 Commandos were programmed to eliminate their targets, follow orders, be loyal to the Consortium, and save other innocent lives.
