HK-50 also had a unique speech trait, where he would vocally prefix every statement he made with a speech conditional that described the type of statement it was. The droid seemed to enjoy observing, and often causing, death and destruction. HK-50's personality programming caused him to appear cruel, extreme bloodlust, arrogance, misanthropic, bordering on sociopathic, to those who encountered him. The HK-50 droid does not show mercy, and even seems to enjoy violence. Although this protocol droid theory soon broke down when a group of HK-50 approached the master fully armed, and attacked him. Due to his appearance, he were often mistaken for protocol droids by many, and he used this to his advantage hiding his true nature in order to covertly achieve his goals, liquidating his prey. The HK-50 assassin droid were designed to look like a simple protocol droid. The primary function of the HK-50 droids, as they stated it, was to 'facilitate communications and terminate hostilities.' HK-50 units were identical in appearance to HK-47, with the primary exception being that they are silver-blue in color instead of HK-47's rusty orange, and while HK-47 had red photoreceptors, HK-50 had yellow eyes. Like their progenitor, these droids possessed incredible linguistic skills and highly sadistic tendencies. The HK-50 droids series was based on the earlier HK-47 assassin droid. We saw them later returning in the footsteps of the Exile to the Telos Military Base Sublevel in the game.

They often grouped together, and opposite to HK-47 who worked alone, HK-50 often worked in teams. Sometime after Revan's disappearance, production continued again under the planning droid turned crime lord G0-T0, who discovered the HK-50 manufacturing facility hidden on Telos IV and reactivated it, disseminating a newly created HK-50 droid army throughout the galaxy searching for the Jedi. However, Revan was captured and his memory was erased before this plan could be realized, and the production on the HK-50 model ceased for several years. HK-47 became the basis for a new model of HK-series assassin droids: the HK-50, which were manufactured in a secret facility on Telos IV. After witnessing HK-47's abilities first-hand, Revan decided that more droids of this design would make efficient agents for his purposes.
