Unidentified Rebel agent ( droid builder ) During the Galactic Civil War , an undercover agent worked for the Alliance to Restore the Republic . Some time after the Battle of Yavin , that agent was as tasked with locating a hidden droid factory on the planet Tatooine , where the Galactic Empire had developed a new series of assassin droids ready to wreck havoc on the galaxy . To give themselves the means of performing that mission , the agent infiltrated the Nkik clan of Jawa , learning the art of droid building under the aegis of Wimateeka . The Rebel agent had to equip several droids with the capabilities they needed to meet the challenges of various missions , such as the ability to talk , arms that could manipulate pulleys or enough power to push crates up inclines . After those training missions were completed , the agent recovered a set of Optical Information Crystal s that revealed the location of the hidden factory . Thanks to a program code reconstructed by putting the crystals ' informations together , the Rebel droid builder managed to re - program the Imperial assassins droids into harmless , dancing ones . History . Learning the way of the builder . At the time of the Galactic Civil War , a diminutive humanoid served within the Alliance to Restore the Republic , also know as the Rebel Alliance , a resistance movement that opposed the tyranny of the reigning Galactic Empire . Despite being still young , that individual became one of the Alliance ' s most trusted secret agents . One day , the Alliance Intelligence reported that the Empire had built a secret droid factory somewhere on Tatooine , a desert , suns - scorched planet in the Arkanis sector . They also learnt that Imperial engineers were creating a new series of assassin droids in that place . Once completed , those dangerous machines would be released to wreak havoc in the galaxy . Intent on locating that hidden factory and reprogramming the droids , the Alliance executive entrusted the diminutive agent with that mission . The agent was brought to Tatooine aboard a CR90 corvette , where they received instructions from C - 3PO and R2 - D2 , a droid duo affiliated with the Alliance heroes Luke Skywalker and Leia Organa . The agent was ordered to pose as a Jawa so he could gain entrance to the sandcrawler of the Nkik clan with the connivance of its leader Wimateeka . After learning to build droids with the Jawas , the Rebel was tasked with creating a robot that could infiltrate the Imperial factory and reprogram the new assassin droids . To assist them in that mission , the agent teamed up with C - 3PO , R2 - D2 and Cammy , a chatty Holocam E - series droid . With the help of his mechanic partners , the agent learnt the art of droid building in the workshop of Wimateeka , proving worthy of the latter ' s approval . He or she put newly built droids through a series of tests and maneuvers in the wastes of Tatooine , preparing for the actual infiltration mission . As a first step , the Rebel tested their droids in the Sandcrawler Training Facility . In that area , the agent could study their new droids ' movement , test their speed or their ability to jump , and check if they were magnetic or not . Following the preliminary test , the Rebel operative began Wimateeka ' s first training mission . The wheeled droid had to pass through a security exit door located at the top of the cliff in the Jundland Wastes . To that end , the droid had to put in place a series of movable enclines by activating switches , taking account of its speed and weight to determine the appropriate slope angle . When the inclines were set , there remained a sizeable gap between the top of the slope and the exit door , which the droid was forced to fill by pushing a wooden crate up the incline . The same mission was repeated once more , although with a legged droid , forcing the droid builder to revise their strategy . In the second test , the agent had to get a droid across two moving conveyor belts that were used to carry crates containing magnetic items . In order to do so , the builder created a droid that was magnetic itself so it could be pulled off the ground by the trams picking up the crates . Againt , that mission was repeated twice with new objectives . On the second round , the builder ' s droid was tasked with rescuing a stranded R5 - series astromech droid that had run out of battery power . In order to help the astromech unit , the agent ' s droid had to pick up a battery located on the other side of the conveyor belts . On the third occurrence of the mission , the agent had to save another stranded droid that needed to be fully re - powered through a power plug and a generator . Reprogramming the assassins . After a series of supplementary missions during which the Rebel agent learned how to build droid , it became necessary to recover a program code that could render the assassin droids harmless . In order to do so , the agent had to recover several Imperial Optical Information Crystal s and take them to the Jawa Data Crystal Information Area , where they could be activated with a laser light generator . One of those crystals was kept in the Mos Eisley Salvage Yard , another in the Phrik Mines , and the last one was kept by a moisture farmer who supported the Rebel Alliance . While the droid builder had just reconstituted the program code , the Jawas informed them that the Imperial factory had been located in the second quadrant of Tatooine . Eventually , the The Rebel ended up building their best droid and had it take a disk with with the program code to the hidden factory , the location of which was now known . The robot trespassed into the Imperial factory and reprogrammed the assassin droids into dancing ones . Wimateeka was so proud of his recruit ' s work that he awarded them with an official droid builder certificate . Personality and traits . The Rebel agent was small enough to go unnoticed amongst the Jawas , a species whose average height and weight were only one meter and thrity kilograms . Behind the scenes . The droid builder was the player character of the " " children - aimed game . The game never specifies the Rebel builder ' s name or gender , allowing the player to identify themselves with the character . Unlike other game characters — like Rookie One from " " or Meetra Surik from " " — the Rebel builder has not been reused in later works , and thus was never given a proper canonical identity . C - 3PO comments how the " young " Rebel looks good as a Jawa , which hints this secret operative might have been a child at the time . This seems to be backed up by the droid builder ' s diminutive height .
