Stauz Czycz Stauz Czycz was a soldier from a world that was razed by the Empire . Holding Darth Vader responsible , he devoted himself and his life utterly to revenge , styling himself as the mercenary Awarru Tark . Biography . When his homeworld was razed by the Empire , Czycz lost everything . Despite his best efforts , Czycz was forced to live with the knowledge that his home was destroyed , and his family dead . Despite the fact that the massacre had been ordered by Palpatine , Czycz held the leader of the attack , Darth Vader , responsible . Devoting the rest of his life towards attaining vengeance , Czycz allowed himself to be surgically altered , implanted with numerous mechanical devices and weapons , while his appearance was changed to make him look like a dark haired Human . Czycz became Awarru Tark . In order to gain access to Vader , Tark became a bounty hunter . He was evidently skilled at this , gaining , as Vader put it , a ' " reputation for results " . His reputation eventually landed Tark on Vader ' s list of mercenary invites when the Sith Lord issued the bounty on Han Solo and Leia Organa in the wake of the Battle of Hoth . Tark was intentionally late , claiming to have been held up in customs on Myrkr . Meeting with Darth Vader in the observation suite aboard the Star Destroyer " Avenger " , Tark initially apologized for his lateness . Vader , mistaking Tark ' s murderous exultation at finally facing his target for the usual aura of a killer , was not impressed with what he termed Tark ' s " posturing " , demanding to they proceed with their business . Tark agreed , tossing four small detonators at the entrance of the suite , sealing the door . Pulling off his cloak , Tark leapt at Vader , attacking with two energy blades projected from his forearms . Vader managed to parry the initial attack with his lightsaber , but Tark suddenly leapt over Vader , attacking him from behind and scoring a hit on Vader ' s back . Vader whirled to parry , fending off Tark ' s attacks but in turn opening himself up for a sudden kick . Having knocked Vader against the wall , Tark attempted to follow up the kick with a volley of attacks , but Vader managed to evade it , and Tark scored merely a hit on the Sith Lord ' s helmet . In desperation , Vader blasted Tark against the chamber ceiling with a Force push , telekinetically pinning him . Tark responded by dropping a series of detonators on Vader , disrupting his concentration . No longer pinned , Tark dropped down and charged Vader . Darth Vader dropped his lightsaber and seized Tark ' s wrists , bending the mercenary ' s energy back towards his own face . Now desperate , Tark activated one of the mechanical weapons concealed within his body . Tark ' s lower face and jaw burst outward , revealing a massive toothy maw ringed by insect - like pincers , while his hands and torso split open to unleash a storm of tiny mechanical tendrils , each tipped with a number of hooked and barbed blades . As Tark ' s blades chewed their way through Vader ' s armor , the Sith Lord telepathically reached into Tark ' s mind . Learning of Tark ' s backstory as a soldier bent on vengeance , Vader became temporarily paralyzed by Tark ' s wrath . However , the mental assault also caused Tark to lose his composure , giving Vader enough time to use the Force to disable a force - field generator implanted in Tark ' s body and reclaim his stolen lightsaber . As a tear escaped from Stauz Czycz ' s Human eye , Darth Vader decapitated him . Legacy . While Czycz ' s attempt at revenge was unsuccessful , his devotion to Vader ' s death and the lengths to which he went in attempt to do so left Vader shaken . The Sith Lord began to reflect on his own life and his own sacrifices made in the name of revenge . Personality and traits . Czycz ' s personality before his " transformation " remains unknown , but afterward , he was marked by his obsessive devotion to avenging himself against Darth Vader . Going to extreme lengths , and feeling that he had nothing else to live for , Czycz allowed himself to be subjected to quite extreme and presumably painful cybernetic augmentation , sacrificing whatever he was in the name of revenge . As a mercenary , he became known for his ability to get results , likely meaning that he was ruthless and determined . In short ; the perfect bounty hunter . In person , he was polite and punctual , explaining his actions and meaning to carry out his business . In the Force , Vader detected his aura to be a hunger for prey , something he initially mistook to be the typical killer ' s attitude . Czycz devoted so much of himself towards ensuring Vader ' s death that the Sith Lord considered him more living weapon than man . However , in the end , Czycz seemed to regain some measure of his former self , Vader ' s invasion of his mind forcing him to relive his most painful memories , shedding a tear moments before his death . Whether this tear was from regret or an overriding sense of failure remains unknown . Powers and abilities . With his cyborg augmentations , Stauz Czycz was a formidable opponent . Projecting twin energy blades from his forearms , he was capable of engaging Darth Vader , a master lightsaber duelist in combat . He demonstrated a super - Human level of speed and agility , enough to give the Sith Lord pause . The blades could parry and lightsaber and were able to shred the armorweave fabric of Vader ' s cape with ease , though they were unable to penetrate Vader ' s helmet . Czycz ' s skills in melee combat were enough to force Vader to resort to telekinesis . Another of his augmentations included a massive array of mechanical tendrils within his body , each tipped with a hooked and barbed metal claw . When forced onto his back foot , Czycz could cause his very flesh to split open , with the claws chewing away at a chosen target in a massive swarm . They had the ability to carve their way through Darth Vader ' s armor in a matter of seconds . In addition to the abilities afforded to him by his augmentations , Czycz also favored small detonators in combat , either throwing them at opponents or sealing entrances and exits with them .
