Sith Warrior ( Galen Marek ) The Sith Warrior , also known as the Dark Apprentice , was the incarnation — created through the Force — of the darkness that resided within Starkiller , a young Human male who was secretly trained in the ways of the dark side by the Sith Lord Darth Vader . A Sith in all but name , Starkiller spent years honing his skills in lightsaber combat and Force techniques as Vader ' s secret apprentice and personal assassin . Aside from being the depiction of Starkiller ' s " dark side , " the Sith Warrior was essentially the culmination of what the Starkiller could have become ; a Dark Lord of the Sith , encased in a suit of armor painfully grafted to his body , who succeeded Vader as the apprentice of Darth Sidious . When Starkiller infiltrated the Jedi Temple on Coruscant for a third and final time , his search for further information on his dead father consequently led to his completion of the Jedi Trials . Trapped in an unconscious state during the final phase of the test , Starkiller was confronted by the Sith Warrior . After a long and brutal duel , Starkiller ultimately emerged victorious . But as he regained consciousness , the specter declared that Starkiller would never escape him . The Sith Warrior later resurfaced on the planet Kashyyyk through another Force vision . But unlike the event in the Jedi Temple , he appeared through Starkiller , who saw himself garbed in the same armor that the warrior possessed . As the Sith Warrior , Starkiller fought and defeated a Jedi Knight in his vision , only to discover immediately afterward that the opponent was his own father . Starkiller ultimately avoided the future that the Sith Warrior represented . He reclaimed his birth name , " Galen Marek , " and re - embraced his Jedi lineage , just before he saved the Rebel Alliance from a premature end at the cost of his own life . Marek ' s sacrifice not only prevented the destruction of the Alliance , but also spared him from the fate that the Sith Warrior represented — a life as Darth Sidious ' slave , trapped inside an armored suit for the purpose of life support . History . Trial of the Spirit . In the year 2 BBY , Darth Vader ' s secret apprentice , codenamed Starkiller embarked on a personal journey to rediscover his origins . The years of training under the relentless tutelage of the Dark Lord of the Sith effectively suppressed the memories of his past and the death of his Jedi father . His search for answers brought him to the ruins of the Jedi Temple , the former headquarters of the fallen Jedi Order , located on the capital world of the Galactic Empire . When the apprentice discovered a holocron inside the Temple ' s Tower of First Knowledge , a gatekeeper appeared in the form of his father and implored him to complete the Jedi Trials . As a result , the apprentice slipped into a state of unconsciousness as his mind was overtaken by a vision in the Force . Within the depths of his own psyche , Starkiller was confronted by his connection to the dark side of the Force , personified in the form of an armored Sith Warrior . Though Starkiller was unaware of the true nature of his opponent , the Sith specter was also a vision of a future in which Starkiller succeeded Darth Vader as Emperor Palpatine ' s dark apprentice . As their duel escalated in ferocity , an attack from Starkiller caused the Sith Warrior ' s helmet to fall off . However , the revelation of his opponent ' s identity caused Starkiller to freeze from the shock of what he saw . Though extremely pale and scarred on the forehead , and with eyes that reflected a deep immersion in the dark side , the Sith Warrior possessed Starkiller ' s face . The Sith Warrior pressed his attack and forced Starkiller on the defensive . As the fight continued , he alternated between his own form and the appearance of Starkiller dressed in the ceremonial robes , posthumously awarded to Jedi Knights after death . Yet despite the warrior ' s combination of saber strikes and Force attacks , Starkiller ultimately emerged victorious after he stabbed the warrior with a lightsaber through the abdomen . As a result , the Sith Warrior ' s body was consumed in a blinding flash of light . Starkiller found himself back inside the chamber where he found the holocron just before his last trial commenced . But when he looked down at his left hand , he saw the pale skin and clawed fingers of the Sith Warrior , whose voice echoed with the declaration that the apprentice would never escape his dark fate . At that moment , the vision ended and left Starkiller uncertain about the exact meaning of what he had just witnessed . Kashyyyk . During a mission on the Wookiee homeworld of Kashyyyk , Starkiller discovered a ruined and abandoned hut . Despite the feeling of a vague sense of familiarity , his repressed memories of the past prevented him from recognizing the ruin as the home of his father , Kento Marek . Upon inspecting the hut , Starkiller saw evidence of a lightsaber duel , and also discovered a blue crystal on the floor . But just as he collected the artifact , the apprentice fell into another Force - induced vision , in which he witnessed and relived a past battle on Kashyyyk through the eyes and actions of his own master , Darth Vader . Through the Dark Lord , the apprentice saw the defeat of the Wookiees , the murder of his father and his own abduction by Vader . The vision suddenly changed and Starkiller , much to his horror , found his appearance altered into the armored form of the Sith Warrior . Trapped within a body composed of both flesh and machine , the apprentice felt more mechanical than alive . Overall , his physical state felt eerily similar to what his master experienced as a cyborg . As Starkiller inspected his new form , he was confronted by another version of himself , one who embraced the light as a Jedi Knight . Embodied and overtaken by the Sith Warrior , Starkiller activated a red - bladed Sith lightsaber and adopted the Juyo stance because of its reputation as the most vicious form of lightsaber combat . Though the Jedi ' s eyes contained sorrow and pity in them , he activated his own lightsaber , which produced a blue blade , and took the defensive stance of Soresu . Starkiller lashed out in a barrage of offensive strikes , and though the Jedi ' s defensive strategy proved difficult to breech , he knew that Soresu could not indefinitely withstand the attacks of Juyo . As the duel dragged on , the dark side that the Sith Warrior embodied became increasingly stronger within Starkiller . When the Jedi seized the offensive , Starkiller relied on his Force abilities to counter his adversary ' s attacks . Utilizing telekinesis to hurl jagged planks from the walls of the hut at the Jedi , Starkiller took advantage of his opponent ' s distraction and attacked with Force lightning . The Jedi struggled to overcome the agonizingly painful effects of the Sith attack in order to use his lightsaber as a superconducting loop , which then redirected Starkiller ' s own attack back at himself . The resulting explosion of Force energy blasted both Sith and Jedi against opposite corners of the hut . The pain inflicted by his own attack , as well as the grizzly sight of his brunt flesh , fueled Starkiller ' s rage and connection to the dark side of the Force . Drawing on his anger , the apprentice willed himself upright and suspended above the floor . With one outstretched arm , he telekinetically lifted his Jedi counterpart in the air , just as Darth Vader had done to Kento Marek years before . The Jedi tried to reason with the apprentice , but to no avail . Starkiller ' s mind had been overtaken by the dark side , and he laughed gloatingly at his hapless opponent . With the Jedi at his mercy , the apprentice unhooked one of the lightsabers from his belted waist and impaled the Jedi ' s shoulder with it . He then used his lightsaber to finish off the Jedi . Despite this , the Jedi remained alive . Annoyed , Starkiller summoned the Jedi ' s own blade to his hand and stabbed him . When the Jedi ' s dead body collapsed on the floor , the apprentice felt the wave of the dark side wash over him . He reveled in the feeling , relished his victory , and saw himself as the living embodiment of power . Just then , however , someone else appeared in the hut and exclaimed his remorse over Starkiller ' s life as a Sith assassin . When the apprentice turned , his lightsaber retrieved and drawn in less time than it took to think about it , he recognized the figure as his late father , the former Jedi Kento Marek . He looked at the body of the fallen Jedi Knight whom Starkiller killed , and then stared once more at the dark side version of his son with grief and loss in his eyes . Before vanishing , he apologized to Starkiller , whom he addressed as " Galen . " Legacy . The death of Galen Marek . Starkiller never lived to become what the Sith Warrior represented as a vision through the Force ; a cybernetic apprentice and Sith assassin of Emperor Palpatine . His master ' s second betrayal on Corellia , coupled with Starkiller ' s attachment to his allies , ultimately left the apprentice disillusioned with the Sith and the Galactic Empire . Hence , he reclaimed his birth name , Galen Marek , and immediately embarked on a mission to rescue the leaders of the newly - formed Alliance to Restore the Republic . His infiltration of the incomplete Death Star culminated in a final duel between Marek and his former master , and resulted in the near death of Darth Vader . Though he was tempted to execute Vader at the behest of Palpatine , Marek chose to reject the dark side of the Force . In the end , he sacrificed his life so that the Rebel leaders could be extracted from the battlestation by the " Rogue Shadow " , piloted by Juno Eclipse . Consequently , Marek ' s premature death prevented his future as a Dark Lord of the Sith . The clones of Galen Marek . Although Galen Marek was dead , the life he could have lived , as reflected by the Sith Warrior , was not destroyed completely . In secret , Darth Vader endeavored to recreate his fallen apprentice . Thus , he brought Marek ' s corpse to Kamino and preserved it as a clone template . With the advanced technology of the Kaminoans at his disposal , the Dark Lord began a long and laborious task of cloning his former apprentice . The ultimate goal was to create a clone who possessed all of Marek ' s power and skills , but none of the emotions that Vader perceived as " weaknesses . " However , cloning of a Force - sensitive subject ' s DNA was regarded as a theoretically impossible achievement , and thus the process was full of trial - and - error steps . But after several months had seen the production of various genetic failures , including a renegade clone who escaped from Kamino , a single clone was successfully engineered without any of his precursors ' flaws . Through the accelerated cloning process , the clone was bred to adulthood within a few standard weeks ; memory flash es of his progenitor ' s life filled him with the knowledge and experience of Galen Marek . The same process had been used on the clones who came before him . The first subjects were physically deformed and far too mentally unbalanced . The more stable versions suffered from an identity crisis , due to the fact that they possessed another man ' s memories . The clone who proved to be " perfect " in Vader ' s eyes , however , compartmentalized Marek ' s memories and was successfully able to separate them from his own experiences . As Darth Vader ' s new apprentice and the only success in a long line of failures , the clone effectively became what the Sith Warrior reflected for Marek — a Sith assassin completely immersed within the dark side of the Force . Powers and abilities . Like Starkiller , the Sith Warrior was a proficient practitioner of the dark side of the Force . His range of techniques included Sith lightning and various forms of telekinesis , such as Force push , Force repulse and Force throw . He was also , much like Galen Marek , extremely skilled in lightsaber combat . He was an expert Djiem So practitioner , but also utilised Dun Moch when required . He displayed incredible reflexes and durability , shown in his first duel with Starkiller , where he manages to remain standing against his opponent for a long time and comes close to defeating him . As a " dark " mirror version of the apprentice , the Sith Warrior also utilized the unorthodox reverse - grip form of Shien . Armor . The Sith Warrior ' s body was encased within a suit of armor , painfully grafted to his flesh and bone , that was designed to inspire fear in both Jedi and Sith alike . The suit also incorporated cybernetic attachments as well . His fingers had been replaced with artificial claws with blades sharp enough to cut bone . His wrists and forearms were an amalgamation of flesh and machine , which continued up to his shoulders and disappeared under a high , metal collar that protected his neck . The skin that remained on his forearms was scorched and disfigured . The armor itself included a ribbed vest of flexible armor plates and a series of leather belts around the wearer ' s waist . Several lightsabers , ranging from Jedi to Sith design , adorned the belts like trophies . Beneath the armored suit , the Sith Warrior wore tight black garments . His face was fully concealed within a helmet that slightly resembled an Ubese mask , but with a Mandalorian - style visor in the center of the face - plate . The overall function of the suit was similar to the armor worn by Darth Vader . Like Vader ' s mask , the Sith Warrior ' s helmet included a breathing apparatus , though the mechanism appeared to be controlled by the wearer , as the breathing pattern was forced and eclectic . However , despite its role as a life - support asset , the Sith Warrior ' s armor excluded the limitations that Vader ' s armor possessed . Whereas Vader was physically hindered by his armor , which also limited his own ability to utilize the dark side of the Force , the Sith Warrior retained the same speed and agility that Starkiller wielded without the armor . Furthermore , the armor preserved the Sith Warrior ' s ability to generate Force lightning and did not appear to limit any of his other techniques either . Behind the scenes . The Sith Warrior wears the same armor that Galen Marek ( codenamed " Starkiller " ) wore in the non - canonical dark side ending of . In this alternate conclusion to the video game , Marek turns back to the dark side of the Force and kills his former master , Darth Vader . However , he fails to assassinate Emperor Palpatine , and thus sustains severe injuries to his body . In order to preserve Marek ' s life , the Emperor encases him within a suit of armor . As the Emperor ' s new apprentice and personal assassin , Marek becomes Lord Starkiller , thus bringing about the " dark future " that the Sith Warrior represented during the Jedi Temple level in " " . During the fight between the apprentice and the Sith Warrior in the Jedi Temple level , the warrior occasionally shape - shifts into a Jedi version of Starkiller , dressed in the ceremonial robes that were posthumously awarded to deceased Jedi . Hence , the Sith Warrior ' s two different forms represented the two versions of the apprentice ' s fate . In the Sith stalker armor , the warrior mirrors Starkiller ' s life as Palpatine ' s apprentice . As the Jedi wearing the ceremonial robes , he reflects the canon ending of the video game — Starkiller ' s death through sacrifice . The Sith Warrior also appears in the novelization . On Kashyyyk , Starkiller experiences a vision in the Force , in which he finds his body altered into the Sith Warrior ' s armored appearance . As he duels with a Jedi Knight version of himself , Starkiller all but completely surrenders himself to the dark side and is thrilled by the power he gains through it . The Sith stalker armor ' s appearance in the Jedi Temple DLC ( Downloadable Content ) level in the Ultimate Sith Edition , as well as its inclusion ( via a Force vision ) in the novel , effectively brings it into the canon . The Sith Warrior ' s voice and appearance were provided by Sam Witwer , the actor who portrayed Galen Marek . There are six lightsabers and extra lightsaber hooks on the apprentice ' s leather belts in this costume . The first of these " trophies " is Starkiller ' s original lightsaber , lost in the vacuum of outer space after his master ' s first betrayal . The other weapons include Rahm Kota ' s lightsaber , retrieved from the defeated Jedi General during the Battle of the TIE Fighter Construction Facility above Nar Shaddaa ; the end piece of a lightsaber pike , taken by Starkiller after his victory over Kazdan Paratus on Raxus Prime ; one half of the double - bladed lightsaber that belonged to Darth Maul ; and Darth Vader ' s lightsaber , taken from him after his death at the hands of his former disciple . Lord Starkiller ' s new weapon , a Sith lightsaber that features three spiked emitter guards , is included his belts as well . In the PS2 / Wii version , the Sith lightsaber has four emitter guards . This battle between Marek and this vision was ranked number four on " Game Informer " < nowiki > ' < / nowiki > s " Top 10 video game shadowselves " in April 2009 . It came just behind the likes of Dark Link from " The Legend of Zelda : Ocarina of Time " , Cecil ' s duel with his Dark Knight form so he could become a paladin from " Final Fantasy IV " , and Dark Samus from the " Metroid " series ' " Metroid Prime Trilogy " coming in at number one .
