Voca Voca was a Human male clone of the bounty hunter Jango Fett . Following the rise of the Galactic Empire , Voca served as a Stormtrooper commander in the 501st Legion , by then under the command of the Sith Lord Darth Vader . Shortly after the disappearance of Admiral Garoche Tarkin , the son of Grand Moff Wilhuff Tarkin , Voca accompanied the Sith and two battalions of the 501st on a mission to locate Tarkin ' s missing son . During the mission he wore a set of " Katarn " - class armor distinguished with blue markings . Ultimately , Darth Vader was the only one who survived the assignment ; Voca and his stormtroopers were ultimately killed by Atoan insurgents as a result of the treachery of Captain Shale , an Imperial officer who secretly supported Atoa against the New Order of Emperor Palpatine . Biography . Skirmish on Atoa . Following a botched assignment to hunt down insurgents in the Ghost Nebula , the Imperial Navy lost contact with an " Imperial I " - class Star Destroyer under the command of Admiral Garoche Tarkin , son of then - Moff Wilhuff Tarkin . In response , Emperor Palpatine commanded his Sith apprentice Darth Vader to find and retrieve the lost admiral with the assistance of the 501st Legion and Captain Shale . Thus , Commander Voca was assigned to serve at Vader ' s side with a detachment of two battalions of stormtroopers from the 501st . After traveling to the Ghost Nebula , Vader and his Imperials landed on Atoa , a planet that the Galactic Empire possessed little intelligence on . Upon discovering a city not far from the area where they landed , Commander Voca reported to Vader that the settlement possessed at least a few hundred armed soldiers and that a scouting party was approaching the Imperials ' position . Vader merely responded by ordering the commander to have the 501st wipe out the scouts ; Voca complied without hesitation . With brutal and merciless efficiency , the 501st stormtroopers immediately began overwhelming the city ' s defenders by sheer force of military power , including the firepower of AT - STs and AT - TEs . Commander Voca remained by Vader ' s side as the Sith Lord participated in the fighting . As the Imperials penetrated deeper into the city , Voca informed Vader that the enemy soldiers were retreating into a watchtower , to which Vader was pleased to learn as he intended to trap them in one location . At that moment however , a lone soldier began shooting at Vader , Voca and the stormtroopers from high ground . Despite having a brief advantage , the soldier was knocked unconscious from behind by Captain Shale . With most of the enemy neutralized , Voca and his troops converged on the watchtower alongside Vader and Shale . After analyzing the watchtower ' s defenses , which included snipers and heavy artillery , it was clear that the Imperials were at a tactical disadvantage . Voca suggested that a walker could effortlessly save them the trouble of destroying the tower , but Vader rejected the idea in favor of capturing the remaining enemy units alive , but only for the purpose of interrogation . While Captain Shale and his troopers covertly climbed up the tower , Vader used the Force to surround the tower in a snowstorm , thus blinding the snipers . Although suffering light casualties in the overall engagement , the plan was a success and the tower was taken ; the last of the city ' s soldiers were captured while the rest were dead . Following Vader ' s order to the letter , Commander Voca had his stormtroopers secure the tower and escorted remaining enemy soldiers to a river located outside of the city . As the captured soldiers knelt down in submission on the bank of the river , Darth Vader demanded that they reveal the location of Admiral Tarkin , or die for failing to do so . The interrogation yielded no relevant information to Vader ' s assignment , however . As a result , Vader ordered Commander Voca and his stormtroopers to sweep the area a second time and to execute anyone in the city who was old enough to wield firearms , all before burning the city to the ground . Having no personal objections to his new orders , Voca merely asked the Sith Lord as to what should be done with the prisoners , to which Vader ordered that they be drowned in the freezing river . Before Voca could carry out any of his orders , however , a boat containing white - robed figures approached the Imperials via the river . The commander raised his weapon to open fire on the mysterious beings , but was ordered by Vader to stand down . A female disembarked from the boat and identified herself as Lady Saro , the High Priestess of Atoa , promising to help Vader and his Imperials in locating whatever they were seeking . Ambushed in Space . Shortly after Darth Vader worked out a compromise with Lady Saro in order to utilize her aid in the search for Admiral Tarkin , the Atoan priestess revealed the location of Tarkin ' s missing Star Destroyer . Accompanied by a squadron of Imperial V - wing starfighters , Commander Voca aided Darth Vader and Captain Shale in searching the Star Destroyer ' s wreckage in outer space . Based on the massive damage to Tarkin ' s warship , Voca concluded that the explosions had to have occurred from within the vessel , thus indicating that sabotage resulted in the Star Destroyer ' s destruction . Before his analysis could be given any further thought , however , the Imperials were caught unawares by a surprise attack by Atoan starfighters , which were able to successfully hide in the debris field since the Imperials neglected to thoroughly sweep the entire area . Although initially caught off guard , Voca and the clones succeeded in repelling the Atoans with the aid of Vader and Shale while only sustaining light casualties . After the brief skirmish , Commander Voca discussed strategy with Captain Shale and Lady Saro while aboard Vader ' s Star Destroyer . While analyzing an world where Garoche Tarkin was believed to be held prisoner , Voca felt that aground assault would be too costly due to the planet ' s global - spanning oceans of hot tar pits . Thus , the clone recommended that they dispatch a recon mission in order to scout the terrain , but Vader rejected the plan and ordered his forces to immediately launch an invasion . Voca obediently obeyed Vader ' s order to prepare the AT - AT Walkers and ground forces as a distraction for the insurgents so that Vader and Shale could personally lead a stealth attack . Despite successfully annihilating the insurgents , albeit at the cost of a few Imperial Walkers and several clone squads , Vader and Shale failed to locate Garoche Tarkin . The missing admiral was not held prisoner by the Atoans as they originally believed , thus causing Vader to suspect that Moff Tarkin ' s son was a traitor to the Empire . Mutiny . Without warning , Captain Shale and his storm commando s betrayed their comrades and attacked all of the officers and clones that remained loyal to Darth Vader . Throughout the Dark Lord ' s Star Destroyer , the 501st stormtroopers were taken by complete surprise as their fellow clones opened fire on them . Although none of the officers survived the mutiny , Commander Voca and a few stormtroopers managed to hold their ground but were pinned down by storm commandos that held the high ground . The tide quickly turned in their favor when Darth Vader arrived . Seizing advantage of the opportunity , Voca and his men aided the Sith Lord in killing the treacherous clones . Gathering the remaining clones of the 501st Legion , Commander Voca and his troops accompanied Lord Vader on a hunt for the traitors — including Captain Shale . But due to Shale ' s subterfuge , massive explosions suddenly went off throughout the Star Destroyer , thus causing massive damages to the entire vessel in a manner exactly the same to the damage on Admiral Tarkin ' s warship . Before heading to the hangar to escape the doomed destroyer , Vader and Voca tried to retrieve Lady Saro , only to see that Shale had already taken the priestess off of the starship . After hunting down and killing the remaining storm commandos , Voca and his soldiers escaped the Star Destroyer just in time by boarding a " Nu " - class attack shuttle piloted by Darth Vader . The explosion caused significant damage to the attack shuttle , causing the vessel to crash - land on a planet located at the heart of the Ghost Nebula . Although Vader , Voca and eight stormtroopers emerged relatively unscathed , the rest of Voca ' s squad perished in the crash . In pursuit of the traitor Shale on foot , Voca and the rest of the clones followed Vader until they found the rest of Shale ' s storm commandos , all of whom were apparently executed . At that moment , Atoan insurgents opened fire on the Imperials . Vader ordered Voca and the rest of the 501st while he personally dealt with the ambushers . While Darth Vader held his own against the enemy , Commander Voca and his men did not fare so well . Outnumbered and outgunned , the clones retreated deeper into the ravine to escape the Atoans who held the high ground . But their escape route was cut off by a group of Atoans led by the former Captain Shale . At that moment , it became apparent that Shale had switched sides and betrayed the Empire for the Atoans . Shale halfheartedly apologized to Commander Voca before his men opened fire on the clones , thus killing Voca and the last remaining stormtroopers that accompanied Vader on the mission . Moments later , Darth Vader was overwhelmed and captured by the insurgents , all of whom turned out to be under the command of Shale , Lady Saro and Garoche Tarkin . Personality and traits . Like his fellow clones , Commander Voca was bred to be a soldier with absolute loyalty , the likes of which override emotional sentiment and morality . As a stormtrooper in the service of the Imperial 501st Legion , Voca was an effective soldier committed to strict obedience and brutal efficiency , especially when bringing the military might of the Galactic Empire down on its enemies . As far as emotions go , Voca was indifferent to Darth Vader ' s brutal tactics ; the content of his orders did not matter as much as simply obeying them did . No different than the vast majority of Fett clones that went on to serve the Empire , Voca had no sense of empathy or moral comprehension , thus enabling him to accept orders that entailed brute military force and the execution of disarmed prisoners . As a tactician , Voca had skill in analyzing the environment for potential hostiles and brainstorming advantages to help win a battle . Rather than sacrifice Imperial lives needlessly , he knew that an Imperial Walker would save his forces a lot of trouble and casualties in destroying a tower held by enemy units . When his idea was rejected by Vader in favor of the more direct approach , Voca did not question the Sith Lord , again due to his conditioning as a totally obedient soldier who complied without hesitation or defiance .
