He operated as the gamemaster in Grakkus the Hutt ' s arena on Nar Shaddaa . He was tasked with training new candidates to fight in the arena , including Luke Skywalker . During Skywalker ' s arena fight with Kongo the Disemboweler , Agent 5241 contacted the Empire to inform them that Skywalker was on Nar Shaddaa . After his mission on Nar Shaddaa was complete , Kreel was given command of an elite group of SCAR troopers , designated Task Force 99 . Biography . Age of the Empire . Kreel was born on the planet Chagar IX . When he was four , Kreel watched a man die . It made him cry like a baby for a dozen more times . Two years later , Kreel watched his own father being murdered in front of him , but he did not cry . His mother was also said to have died in the arenas . He then started to kill people and worked in the fighting pit s . Kreel made the fighting pits his way of life in order to survive . Later , Kreel first saw the beautiful sight of the Galactic Empire ' s stormtrooper s . After the Empire toppled Chagar IX ' s warlord s and shut down the fighting pits , Kreel and his people were given jobs , a sense of purpose , and peace . When he was old enough , Kreel joined the Stormtrooper Corps . He then went to the Imperial Academy , where he became friends with a ranger named Izak Anzio of Agamar . During their first mission together , Izak was killed by the Rebels ' mortars before their transport landed . Kreel then killed every Rebel he could find that day and vowed to continue doing so . Kreel eventually became a sergeant in the 501st Legion . Infiltrating Grakkus ' s Palace . He was then recruited by the Sith Lord , Darth Vader for a deep undercover assignment ; to infiltrate Grakkus the Hutt ' s palace on Nar Shaddaa . He posed as one of Grakkus ' s greatest fighting slaves that he had bought . In his role , Kreel trained Wookiee s , lizard men and space pirate s to fight in the arena for Grakkus and his audience . He called himself the " Gamemaster " . Eventually , he was given Luke Skywalker to train for Grakkus ' s games . Along with the MagnaGuards , Kreel taught Skywalker how to fight . He spoke with Grakkus and watched as the MagnaGuards fought Skywalker . Later , he was shown the beast that Skywalker would face . Kreel then took Skywalker to the arena to fight Kongo the Disemboweler . Kreel soon contacted a group of TIE / ln space superiority starfighter s , informing them that Skywalker was there . Kreel triggered Kongo ' s shock collar and then took out Grakkus ' s MagnaGuards using a lightsaber . He then arrested Grakkus , telling him that his arena was closed . He was joined by several of the TIE pilots who surrounded Skywalker . However , as they were taking Grakkus and Skywalker , Grakkus initiated an E . M . P . that disabled Kreel ' s and the TIE pilots guns . Kreel then drew his lightsaber as Kongo was revived . Kreel attempted to subdue Skywalker but was attacked by Grakkus . He ordered the pilot s and stormtroopers to capture Skywalker and his allies . Afterwards , Kreel spoke with Vader about Skywalker as he showed the Sith Lord Grakkus ' collection of Jedi artifacts . Task Force 99 . Not long after Nar Shaddaa , Kreel was given command of a SCAR trooper squad , Task Force 99 . Kreel and the squad then went to Sunspot Prison to find Kolar Ludd . Kreel and his squad were given a new assignment , on the Ghost Moon . There , they were able to shoot down the Rebels ' Taylander shuttle . He and his Squad then attacked of the rebel forces , with Kreel destroying a tank with his lightsaber . The attack was successful , with Kreel and his squad capturing Admiral Verette , and interrogating him . Kreel then had Verette tied to his shuttle and sent it to the captured Star Destroyer " Harbinger " as distraction , while he and his SCAR troopers boarded the " Harbinger " to retake it . Kreel then fought and dueled Skywalker , confirming to Luke that he was the Gamemaster from Grakkus ' s arena . During the fighting , Kreel was contacted by Vader and was warned not to injure Skywalker - a contact that allowed Skywalker to sense Vader ' s presence , leaving him distracted . Kreel took advantage of Luke ' s attempt to use The Force , which he claimed to just get in the way of true fighting skill - but before he could fully overpower the young Jedi , Luke struck out with a Force push that rocked the entire Star Destroyer , trapping Kreel under wreckage and debris . While Luke and the others escaped , Kreel ordered his team to salvage the mission by destroying the Star Destroyer , while he used his lightsaber to cut off his own arm at the shoulder , allowing him to rejoin them as they escaped the ship . While Vader was furious that Kreel and his SCAR team had thoroughly failed in every one of their objectives , Kreel and the Task Force escaped the brunt of his wrath by presenting a valuable captive - the Protocol droid C - 3PO . Kreel and SCAR Squadron took 3PO to the " Devastator " where they attempted to interrogate him in order to find the Rebel fleet or any new bases . However , Kreel was ordered to get rid of 3PO by Vader . Despite Vader ' s orders , Kreel decided to use 3PO as bait to lure the Rebels to them .
