Fan Casting HK-50 in Star Wars: Knights of the Old Republic 2 - The Sith Lords

The HK-50 series droid are assassin/protocol droid models designed by Revan after the Mandalorian Wars. Like their predecessors, these droids possessed incredible linguistic skills and highly sadistic tendencies. The primary function of the HK-50 droids, as they state it, are to 'facilitate communications and terminate hostilities.' In accordance with the usual perceptions of all HK models, the best way to terminate hostilities was to kill everything present. HK-50 units were identical in appearance to HK-47, with the primary exception being that they are 'a rather poor shade of durasteel' in color instead of HK-47's rusty red.
