Droid Revolution The Droid Revolution was a threat most of the galactic public never knew existed . It was a massive revolt planned by the IG assassin droids IG - 88 A , B , C , and D which never occurred as planned . Their plan was to use massive armies of droids to exterminate all the " inferior biologicals " that plagued the galaxy . They went about creating an army by implanting sleeper codes into droids that would turn on their biological masters when the IGs activated the signal . Their plot was ended with IG - 88A ' s destruction at the Death Star II . Origins . The revolution started when IG - 88A was created and activated on Halowan by Holowan Laboratories during Project Phlutdroid . IG - 88 realized that the Human scientists were a threat to his primary programming as an assassin droid when they tried to shut him down after realizing that his sentience programming was too powerful to control . He decided that all biological beings were inferior to droids , and then turned against his creators and killed them within seconds . He then continued to activate the other IG - 88s , copying his consciousness into each , and designating them B , C , and D in order of their activation . Then , together with fellow droid IG - 72 , who agreed to help them get off Halowan , they escaped the facility , carving a swath of destruction along the way . Insurrection on Mechis III . The IG - 88s took off on a ship towards the foundry world of Mechis III . Their first step was to take over the world , one of the galaxy ' s largest droid manufacturers . They planned to use the planet ' s vast industrial complexes to construct a droid army for their revolution , but first they had to deal with the biological beings on the planet . As they flew toward the planet in their ship , they simply hacked into the planet ' s security system , rerouted the planet ' s computer systems and transmitted a code to transfer their sentience into all droid minds . Before long , all of Mechis III ' s droid operators had sentience of their own , and were under the control of the assassin droids . It was here that the IG - 88s took control of a servant droid , told it their plan , and instructed it what to do . The droid in question was 3D - 4X , a common butler droid for the head supervisor , Administrator Hekis Thun . While delivering Hekis ' s tea and daily report , 3D - 4X pulled out a blaster pistol and shot Hekis dead , thus starting the first uprising of the Droid Revolution . The droid operatives on the planet followed their orders and rose against their biological masters , and killed all 73 on - planet Human staff within five minutes . The entire planet was now in the hands of the IG - 88s , before they had ever set foot on its surface . Their plan was to mass - produce millions of droids , with embedded sentience and then ship them out all over the galaxy . Thus , when the signal was given , all of these droids would turn on their masters . To make it seem as if nothing had occurred , the droids constructed doctored image systems , so that when Mechis III was contacted , they would think that they were talking to an organic being . To all eyes , was given the impression that biological beings were still running Mechis III . All was going well , but the IG - 88 ' s feared that soon their luck would run out , and that they might be discovered . They all agreed that they would take jobs as bounty hunters , with IG - 88B as the " face " of the group , in order to lead the Imperial authorities away from their true objective . A Close Call . Soon , around 0 ABY , the Empire contacted Mechis III , to construct an order of Arakyd probe droids . The IG - 88 ' s took this opportunity , and implanted spy programming into the probes , so that at the same time that the probes were working for the Empire , they were spying for them . The closest the revolution ever came to getting discovered was when the Sith Lord , Darth Vader came to oversee the production of his Arakyd Vipers . However , the droids masked their presence well , and Vader merely sensed a slight disturbance . Later in 1 ABY , IG - 88 began production of droids in Nym ' s Factory Compound on Lok . A group of spacers attacked the compound and defeated the droid army , shutting down the factory and causing a temporary setback to IG - 88 ' s plans . Death Star II . When IG - 88A received information that the Empire was building a new and more powerful Death Star , he decided to upload his consciousness into the Death Star ' s central computer core and become the ultimate force in the universe . To do this the droids had to create a false computer core to store IG - 88 in . By the time the foundries on Mechis III churned one out , IG - 88B and C had been destroyed by the bounty hunter Boba Fett , and IG - 88D was killed by Dash Rendar in the Ord Mantell Junkyard . IG - 88A was now on his own . He then boarded an identical shuttle to the one they would intercept which carried 100 droids disguised as stormtroopers and the computer core . The droids then intercepted the Imperial shuttle carrying the Death Star ' s computer core . They destroyed the escort and eventually the vessel itself . Onboard , IG - 88A was surprised to find Supervisor Gurdun who had overseen Project Phlutdroid . When Gurdun told him that he should be gracious toward him , for commissioning his construction , he thanked him before planting several explosives on the vessel . Meanwhile , his mechanical stormtroopers carried the core out and downloaded its contents onto their modified core . When the Imperials installed the core , IG - 88A literally became the Death Star , with complete access and control to all systems . None of the Imperial personnel knew , although Palpatine suspected his presence when a series of doors in his throne room opened and closed wildly . The mechanical stormtroopers were scattered throughout the space station doing various things . His presence was almost revealed when one of these was crippled by a fallen crane . When the sparks coming from his legs were seen , it self - destructed , killing all the witnesses present . Endgame . When the Alliance to Restore the Republic attacked the Death Star , IG - 88A fired the superlaser at the Rebel fleet , letting the Imperials believe they were in control , while he prepared to transmit his master control signal that would cause all droids to turn on their masters . However , he couldn ' t care less about this war between biologicals , he was only concerned with his plans , which were about to come into being . IG - 88A was now preparing to send out the signal to droids everywhere , when the Rebel General Lando Calrissian in the " Millennium Falcon " and Wedge Antilles in his X - wing , shot at the Death Star ' s main reactor , causing a chain reaction which destroyed the entire space station and ended IG - 88A ' s plans for galactic conquest .
