HK - 50 series assassin droid The HK - 50 series assassin droid was a HK series assassin / protocol droid model 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 stated it , was to " facilitate communications and terminate hostilities . " In accordance with the usual perceptions of HK model assassin droid , 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 . History . The HK - 50 droids were first designed and manufactured in secret by the Jedi turned Sith Revan for his war against the Republic . Further modifying and improving the designs of his first HK model , HK - 47 , the HK - 50s were to be used as saboteurs aboard Republic warships . The plan was hauled and production ceased after the Dark Lord was captured by the Jedi Council . 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 the newly created HK - 50 droids throughout the galaxy searching for the Jedi . HK - 50 assassin droids were often able to successfully pose as protocol droids and they infiltrated much of the Galactic Republic fleet in doing so . Negotiations where HK - 50s were used to translate often did not conclude well , as their cruel and violent desires influenced their interpretations of the various spoken languages . The hunt for the last Jedi . After G0 - T0 reactivated the HK - 50s , he sent them out among the galaxy to hunt down Meetra Surik , who was believed to be the last of the Jedi . One HK - 50 managed to infiltrate the Republic capital ship : " Harbinger , " when he managed to sabotage the ship ' s protocol droid , made it step on a frag mine , then stepped in as it ' s replacement . The HK - 50 was present when Surik was taken aboard as a passenger . The assassin droid forged orders that Surik report to the medical bay for automated and mandatory injections . The HK - 50 had programmed a kolto tank to inject Surik with a dose of juma juice sedatives that would be lethal to a non - Jedi , but which would only render her unconscious . The HK - 50 then locked the unconcious Surik in the ship ' s more armored cargo hold and began to sabotage the " Harbinger " , creating a cascade of failures that affected the communications , engines , and weapons , effectively disabling the ship . While the Sith forces arrived to collect Surik , the plans of the HK - 50 were foiled when Kreia , flying in the " Ebon Hawk " , was brought on board the " Harbinger " and rescued Surik . The " Ebon Hawk " had been pursued by and fired upon by a Sith capital ship . When the Sith ship was investigated , cloaked Sith assassins boarded the " Harbinger " and seized it . Kreia and Surik escaped the ship on the " Ebon Hawk " , but the HK - 50 unit tagged along . While the " Ebon Hawk " suffered further damage in the escape , the HK - 50 hid itself in the ship ' s storage compartment , but became locked in . It managed to slice access to the door and escape , attacking the ship ' s two astromech droids : T3 - M4 and C3 - FD . Sabotage of the Peragus Mining Facility . The " Ebon Hawk " , despite severe damage , made its way to the Peragus Mining Facility . Once there , the HK - 50 again posed as a protocol droid and began to sabotage the facility much like he did the " Harbinger " . These included : recording the maintenance officer ' s voice and access codes to pose as him ; sending a signal to the " Harbinger " , before disabling most communication systems in and out of the facility ; inciting a division in the miners over how to deal with the Jedi ( as she had a bounty on her head ) , thus preventing coordinated resistance ; access and modify the mining droid ' s behavior cores , causing them to attack the mining crew ( as well as begin to repair and ready the " Ebon Hawk " for escape ) ; slicing the medical bay ' s systems to cause the kolto tanks to inject all the patients with a lethal dose of sedatives ( being sure the the dosage wouldn ' t kill the Jedi exile , only keep them unconscious ) ; placing and detonating improvised explosives through out the facility , thus force an emergency lock down and gather the miners into emergency sections of the station ( well away from any system controls ) ; flooding the dormitories with toxic gases ; then finish off any survivors using an Aratech 500 portable mining laser . By the time sedatives wore off and Surik regained consciousness , every member of the mining station has been killed . Upon the reawakening of the Jedi exile , HK - 50 continued to try and subvert their escape . Ambushing T3 - M4 in the fuel depo and badly damaging him , to try and stop him from opening any escape routes for the exile , before disposing of him in the stations ' ship refueling tunnel ; executing the station ' s maintenance officer to prevent him telling the stations ' access codes ; slicing the fuel depot ' s systems to force it to lock down and start venting fuel onto exterior catwalks , severing access to the hanger bay ; and trying to convince Surik to return to the medical bay to await " rescue " . Despite delaying them until the arrival of the " Harbinger " , the exile and her companions successfully formed and began to execute an escape to reach the " Ebon Hawk " . This forced the HK - 50 to confront the group directly . He was destroyed in the ensuing fight , and his vocabulator salvaged by Surik . Ambush on Telos IV . Surik , and her companions , encountered more HK - 50s on the planet of Telos IV . While searching an abandoned military base , they found a damaged HK - 50 near a collapsed tunnel . Upon reactivating him , he wordlessly followed them a short distance , before malfunctioning and exploding . Not long after Surik ' s team commandeered a shuttle to the planet ' s polar region , a team of HK - 50s made it to the facility , trying to catch up to the exile . They discovered Surik ' s shuttle ' s course and dispatched another team of HK - 50s to intercept them at the Jedi ' s destination . Reaching Surik ' s intended destination first , the team of HK - 50s shot down the Jedi ' s shuttle . Detecting that Surik was still alive , they quickly activated mines and prepared to fight their quarry if necessary . Much to the HK - 50s ' relief , Surik awakened soon after , as they only wanted to disable the ship and they had worried that Surik may have been seriously injured in the crash . They questioned why Surik would have come to the polar region , since their sensors could detect no reason . The HK - 50s were defeated by Surik ' s team , and one of their control cluster components salvaged by Surik . Characteristics . The HK - 50s all exhibit a number of traits common to the HK series droids , including : cruelty , extreme blood - lust , misanthropy , a fair amount of ( somewhat justified ) arrogance , remarkable proficiency in assassination and combat , a rather deceptive , devious , opportunistic method of causing deaths ( indirectly or otherwise ) , and were quite psychopathic . Unlike most HK models , the HK - 50s were designed around mass causality attacks and sabotage . Originally intended to destroy Republic warships from the inside out , the HK - 50s ' ' philosophy of murder ' was that murder is about " wanton slaughter " and " body count " , causing as many causalities with the least amount of effort . In order to be more easily accepted onto and destroy Republic ships , they were left unpainted ( as opposed to the rusty red colors of previous models ) , their vocabulators were improved by remove intimidating static , each had a powerful explosive installed in their chest as a last resort . They were programmed to be more polite , submissive acting ( until their cover was blown ) , cooperative with one another to better coordinate attacks , and subtly destabilize negotiations to create violent outcomes . Upon being reactivated by G0 - T0 , the HK - 50s were repurposed to hunt down and capture the last Jedi , demonstrating extensive knowledge of how to combat Jedi . However , due to being ordered to bring Surik back in one piece , the HK - 50s were far more gentle and merciful towards her than anyone else . Using violence only as a last resort to bring her in and expressing relief when she survived their ambush on Telos IV unharmed . A noticeable flaw in their design is they are prone to hint their true nature to would be targets , via indirect boasting of their actions and abilities , often followed by claiming the hint was either a sarcastic remark , a turn of phrase , or a malfunction in their vocabulator . Also , despite being capable of performing the functions of a protocol droid to better disguise themselves as one , they were noted as not following commands very well . Behind the scenes . Though the HK - 50 droid factory on Telos ( In the Military Base Sublevel ) was cut from the game due to deadline constraints , HK - 47 was supposed to discover its location . HK - 47 would have gone to the factory and , having been unable to persuade the HK - 50s to join the cause of the Exile , would have enlisted the help of the ( not quite bug free ) HK - 51 droids . The HK - 51 units would later come to HK - 47 ' s aid against their manufacturer , G0 - T0 , in a final confrontation on Malachor V . While in the factory , HK - 47 would discover the HK - 50s ' entire plan and more info including the Kossa Prime sector , a location where the HK - 50s would normally operate . Commissioned to be built by Revan , they were shut down for a long time due to his capture by the Jedi . Later , they were reactivated by G0 - T0 who ordered them to bring all Jedi to him . He added that if the Jedi would not go , to destroy them . The HK - 50s themselves claim that they do not know how the factory on Telos came to be . HK - 50 was included as a part of the " build - a - droid " series of the Hasbro Star Wars toy line , where various pieces were included in packages to assemble upon collecting of all pieces .
