HK - 55 HK - 55 was a HK - series assassin droid that served the Sith Lord Lana Beniko during the conquest of the galaxy by the Eternal Empire and afterwards . He was programmed as a bodyguard , but also functioned as an assassin droid when required . After his destruction during the Battle of Asylum , he was eventually rebuilt and brought into the service of the Outlander . Biography . Rescuing the Outlander . In 3632 BBY , HK - 55 assisted his masters Lana Beniko and Koth Vortena to rescue the Outlander from Arcann ' s carbonite prison on Zakuul . HK remained with Koth in their escape shuttle while Lana and T7 - O1 infiltrated the prison . However , their prison break didn ' t go unnoticed , as Zakuulan forces managed to shoot down their shuttle . The pair managed to fight off Eternal Empire troopers before getting the shuttle flying again , arriving in time to rescue Lana and the Outlander from Vaylin . HK - 55 personally helped the Outlander up when the hero nearly fell off the boarding ramp . Finding the Gravestone . Unfortunately , the damage Vaylin had done caused the party ' s shuttle to crash into the Endless Swamp . Surviving the crash , HK - 55 announced to his masters that he had detected a large technological object in the swamp . HK - 55 accompanied the Outlander in traversing the swamp , while the others stayed behind to conceal evidence of their crash , before they find the object , revealed to be a derelict frigate . When Koth and Lana rejoined them , HK - 55 informed him that the architecture of the starship did not resemble Zakuulan design , ancient or modern . Koth identified the ship as " Gravestone " , the legendary starship that singlehandedly fought the Eternal Fleet and won . The " Gravestone ' s " mere existence convinced Koth that their victory against Arcann was assured . After killing the creatures that had taken residence in the " Gravestone " , HK - 55 took up a patrol routine while his masters gathered parts and supplies , eliminating skytrooper scouts that he encountered . Later returning to the " Gravestone " to take up a guard post , HK - 55 soon spotted an iknayid that somehow evaded his shots . HK - 55 furiously chased the creature before running into a whole pack of iknayids , which he promptly dispatched . No sooner was the " Gravestone " repaired did the Eternal Empire came bearing down on them . During the fighting , the party was joined by Senya Tirall , a Knight defector . Koth refused to trust as the ex - Knight spent years hunting him down for desertion . HK - 55 then reminded his masters that enemy reinforcements were on the way , so Koth tabled the argument as they managed to get the " Gravestone " off the ground . The Eternal Fleet arrived to stop them and opened fire . HK - 55 fought with the Outlander against skytrooper boarding parties as they made their way to the gunner station . Firing the omnicannon , they were able to destroy more than two dozen Eternal Fleet warship s before escaping into hyperspace . Unfortunately , using the omnicannon shorted out the hyperdrive , causing the " Gravestone " to drop out of hyperspace in the middle of nowhere . While awaiting repairs , HK - 55 secretly monitored everyone ' s activities while exploring the ship . He later ran into the Outlander to ask if the " meatbag bickering " had finally ended . HK - 55 then mentioned that several sections of the " Gravestone " were sealed off before adding that while examining a mysterious monolith to determine if it could be weaponize , he was interrupted by Senya . Asylum . After arriving at the shadowport of Asylum and meeting with Koth ' s crew , Koth requested the Outlander find his engineer Tora . HK - 55 accompanied the Outlander because he had Tora ' s image in his databanks . After fighting through the Starbolts gang , they found Tora in deep trouble with another gang leader named Tanno Vik . When Vik declared his intention to punish Tora for insulting down him and his mother , HK - 55 threatened to relieve him of his arms . After the Outlander resolved the situation , they went to meet with Senya , who wanted to introduce the Outlander to potential allies . She then opened a concealed door but before HK - 55 could enter , he was hit with an electromagnetic pulse that incapacitated him and wiped his memory . When HK - 55 came to , he began wandering Asylum before Lana found him and brought him back to the " Gravestone " . Koth quickly assumed that Senya had betrayed them but Lana believed that Senya ' s contacts were the real danger and asked HK - 55 where he last woke up . Gathering the crew , HK - 55 led them to the concealed entrance . Storming the sanctuary , they found the Outlander in a standoff with the Scions of Zakuul . The Scion leader , Heskal , revealed to all that the reason why they couldn ' t see the Outlander ' s future is that Emperor Valkorion had survived within the Outlander ' s mind . HK - 55 promptly scanned the Outlander ' s brain and found no evidence to suggest that another mind could be inhabiting it . Lady of Sorrow . Senya soon delivered another revelation as she identified herself as Arcann and Vaylin ' s mother . The Outlander ' s party then returned to the " Gravestone " , where Koth had it out with Senya for lying to them . HK - 55 soon interrupted his tirade , announcing that T7 had passed along a message from the Lady of Sorrow , an elusive information broker operating on Zakuul , who desired to establish a dialogue with the " Gravestone ' s " computers . HK - 55 then remained behind to purge the remaining alien creatures aboard the ship while the Outlander and Senya traveled to Zakuul to recruit the Lady of Sorrow . The Lady of Sorrow was later revealed to be an advanced droid named SCORPIO . Upon the Outlander ' s return to Asylum , SCORPIO requested full access to mainframe , but was delegated to the hyperdrive instead . When HK - 55 threatened SCORPIO , she insulted his lack of intelligence . Battle of Asylum . Soon after the Outlander was called to the Scions ' hideout by Heskal Asylum came under attack by Arcann ' s forces . During the fighting , Arcann ' s forces took control of the control spar which powered the docking clamps holding the " Gravestone " , preventing them from escaping . HK - 55 fought to meet up with Koth before proceeding to hold off the enemy as the Outlander went ahead to the control spar to free the " Gravestone " . HK - 55 subsequently went on to join his master as the Outlander was confronted by Arcann . After a long , tenuous fight , Arcann was about to unleash a blast of Force energy to kill the Outlander , forcing HK - 55 to interpose himself between Arcann and his master . This action saved the Outlander , but caused HK - 55 to suffer severe damage and shutdown . Reconstruction . The damage done by Arcann ' s attack was initially deemed to be irreparable , but Dr . Juvard Illip Oggurobb , chief scientist for the new Alliance that had risen to fight against Zakuul , was able to rebuild HK - 55 at his laboratory on Odessen , albeit with some modifications to his chassis . However , HK - 55 ' s memory core was not recoverable , resulting in HK ' s programming being restored to factory settings and complete loss of memory to any events prior to his reactivation . Dr . Oggurobb called on the Outlander to assist in making the final calibrations to HK - 55 ' s security and assassination programming . The Outlander initially found HK - 55 in the research lab , blasting every droid in the room to scrap while the terrified lab technicians scurried out of his line of fire , having opened fire before his test was ready to secure a tactical advantage . With the Outlander ' s aid , HK - 55 conducted a series of scenarios to refine his targeting subroutines to the Outlander ' s satisfaction . Shroud of Memory . At some point , HK - 55 woke up in an unknown location , restrained to an interrogation table . He was greeted by an excitable droid named Z0 - 0M , who released him at his request . Subsequently , a hologram of his captor was revealed to be the terrorist codenamed the Shroud , who revealed that he had copied HK ' s memory core to give him access to Odessen base , where he was planning on planting bombs to destroy it and the Outlander . The Shroud then signed off , summoning battle droids and mercenaries to subdue HK . Zeeyo chose to defend HK , calling him her friend , and discovered that her chassis contained an impressive array of weapons . Fighting their way through the Shroud ' s base , the Coil , HK and Zeeyo discovered the Shroud ' s holorecordings , detailing his unrelenting hatred for the Outlander for ruining his plans of galactic conquest ; a museum of droid heads the Shroud had replicated , including a copy of HK - 47 ' s head ; and a captive Exarch named Malforia . All the while , Zeeyo began experiencing periodic reboots that regularly wiped her memory , which HK theorized was caused by an electrical surge . Additionally , during their confrontation with Malforia , Zeeyo discovers that she ' s a replicator droid , capable of changing her appearance to resemble anyone she had just met . Upon ascending from the underwater portion of the Coil to the asteroid in space linked by a skyhook and reaching the hanger , HK and Zeeyo come face - to - face with another HK - 55 . This HK unit ' s design was copied from the original HK - 55 as he was before the Battle of Asylum , lacking the battlescars and customized repairs the original HK - 55 had received since . The duplicate HK - 55 declared Zeeyo the Shroud ' s property , showing them a holorecording of Zeeyo talking to the Shroud , revealing that she was responsible for capturing HK and was planning on wiping his memory with an electrical surge , only to accidentally get affected herself . HK - 55 and Zeeyo then fight against his duplicate . However , upon critically damaging the replica HK - 55 , the base began to initiate its self - destruct and the computer requested the deactivation code . Zeeyo pleaded with the duplicate HK - 55 to stop the self - destruct , but he merely replied that the computer wasn ' t talking to him before expiring . With time running out , HK - 55 and Zeeyo defended their escape ship from the mercenaries attempting to take it , before escaping the base ' s destruction . Upon returning to Odessen and confronting the Shroud , to the droids ' surprise , the Human began to act all nervous , who claimed that Zeeyo was the true Shroud . As he explained , he was the fifty - first person to be surgically altered to resemble her Human male guise , and coached using the very holorecordings the droids discovered at the Coil , as the true Shroud never put herself at risk . No longer wanting to destroy the Alliance base , Zeeyo stepped up to her subordinate and demanded that he stop it . The bomb computer then recognized her as the true Shroud , and deactivated all the bombs . Behind the scenes . HK - 55 is a companion character in the digital expansion " " for the video game " " .
