Biography . A feminine , third class EV supervisor droid manufactured by MerenData , EV - 9D9 , also known or simply as 9D9 , was originally a peaceful moisture vaporator mechanic on the planet Tatooine . However , she had a programming defect that caused her to exhibit cruelty towards other droid s , a flaw many other EV units shared . She was acquired by the Hutt crime lord Jabba Desilijic Tiure , who made her chief of Cyborg Operations at his Tatooine palace , a position she was well suited for after being reprogrammed in a Mos Eisley spaceport scrapyard . She was one of the few EV units to escape MerenData ' s mass recall . EV - 9D9 converted a dank boiler room in the murky depths of the palace ' s dungeons into a droid " assessment " room , in actuality a grim torture chamber , where her devotee , 8D8 , an 8D - series smelter droid reprogrammed for sadism , assisted her in terrorizing Jabba ' s droid pool into submission . In the year 0 BBY , 261 , a rogue Imperial astromech droid , was captured and brought to Jabba ' s Palace , where he was forced to join its droid pool . However , the droid was able to escape , making EV - 9D9 furious . When the Trandoshan bounty hunter Bossk , working to retrieve the droid for the Empire , tracked it to the palace , the supervisor droid explained that 261 had escaped , claiming that he would soon learn some respect . Bossk later recovered the droid from a clan of Jawa s and brought it back to the Empire . After the Jedi Knight Luke Skywalker gifted Jabba R2 - D2 and C - 3PO in 4 ABY , shortly before the Battle of Endor , they were escorted down to EV - 9D9 ' s torture chamber so she could assign them positions in her master ' s droid pool . C - 3PO , a protocol droid , was made Jabba ' s new interpreter , as his last one was disintegrated after it had angered him , and was fitted with a restraining bolt before being returned to the palace ' s main audience chamber , and R2 - D2 , an astromech droid , was forced to serve drinks aboard Jabba ' s sail barge , the " Khetanna " . However , R2 - D2 was actually tasked with infiltrating the palace ' s droid pool so that he could assist in the rescue of Han Solo from the Hutt ' s clutches , a mission that ultimately resulted in Jabba ' s demise , after which EV - 9D9 was deactivated with the rest of the palace ' s droid pool . Characteristics . Originally peaceful and hardworking , EV - 9D9 was corrupted by a programming flaw and some very nasty reprogramming . A malicious , sadistic , and psychotic mechanic murderer , she enjoyed tormenting and dismembering other droids , reveling in working them until they fell apart or their processor s blew and employing bizarre forms of droid torture to increase motivation . EV - 9D9 relished her role as taskmaster of all the palace ' s droids and was quickly annoyed with the antics of C - 3PO , cutting him off whenever she got the answers she wanted or when he started to stray from the question at hand . When R2 - D2 started acting feistily towards her , EV - 9D9 assigned him to her master ' s sail barge to teach him respect . A gangly bronze and silver colored mechanical with feminine programming , EV - 9D9 was missing various parts , lending her a skeletal appearance . Her manipulator arms and legs were motivated by exposed pistons , and both of her hands terminated in three multi - jointed digits . She stood at 1 . 9 meter s in height and had three yellow photoreceptor s , one of which she custom - fitted to allow herself to " see " droid pain . EV - 9D9 had a degraded logic center and spoke with synthesized female voice that sounded as if it had been stolen from an elderly prison matron . As she spoke , her hinged vocoder flapped up and down beneath her sharp metal chin , simulating the movement of a mouth . Equipment . EV - 9D9 performed her duties while sitting behind an ancient , rickety computer console in the palace ' s boiler room . Behind the scenes . Originally created for the 1983 film , EV - 9D9 first appeared in a " Star Wars " Legends written by James Kahn and released on May 12 , 1983 , thirteen days before the film was released in theaters on May 25 . The character was identified as EV - 9D9 in the novel , a name that originated in the third draft of " Return of the Jedi " but was not used in the final film . This name was established to be canon by " Ultimate Star Wars " , a reference book written by Patricia Barr , Adam Bray , Daniel Wallace , and Ryder Windham and released on April 28 , 2015 . EV - 9D9 appeared as early as the rough draft of the " Revenge of the Jedi " script , where she was known as U - 8D8 . In the revised second draft , she was renamed EV - 8D8 . In the third draft , she received her final name and her smelter droid assistant instead inherited the name 8D8 . She was portrayed using a marionette created by Bill Hargreaves and Steve Short , which was based on Ralph McQuarrie concept art of an assassin droid , and was voiced on set by director Richard Marquand , whose voice was later redubbed during post - production . At one point in the production of " Return of the Jedi " , EV - 9D9 was to be able to walk , though it was later decided that she would sit after the special effects department failed to make it work by George Lucas ' deadline . An interactive gallery of EV - 9D9 ' s marionette was included on Bonus Disc 2 of " " , a set that comprised the first six main " Star Wars " films along with three additional discs of bonus material that was released on September 12 , 2011 .
