11 - 4D / Legends 11 - 4D , pronounced OneOne - FourDee and often referred to as 4D or FourDee , was a masculine - programmed , multi - appendaged bipedal medical droid that served under several masters in the decades preceding the Clone Wars . 11 - 4D originally worked in a medical facility on the planet Obroa - skai before the Togruta Ellin Lah , captain of the freighter " Woebegone " , became 11 - 4D ' s new owner . In 67 BBY , the Muun Dark Lord of the Sith Darth Plagueis killed the entire crew during the freighter ' s trip to Ithor and took 11 - 4D into his possession , with the droid easily switching masters to the Muun . From then on , 11 - 4D helped his master with Plagueis ' s work , including the Muun ' s search for immortality . The droid helped Plagueis track down three Force - sensitives that the Bith Sith Lord Darth Venamis , whom Plagueis had captured after dueling and defeating him , had been considering as possible apprentices . 11 - 4D and Plagueis tracked the first , a shapeshifting Shi ' ido , to the planet Lianna , where they later captured the Shi ' ido before letting him go . After Plagueis found the second on the planet Saleucami , 11 - 4D and the Muun located the last , a Nautolan by the name of Naat Lare , on the world of Abraxin ; Lare died in a confrontation with two Jedi later the same day that 11 - 4D and his master found him . A year after meeting Plagueis , 11 - 4D was introduced to the young Naboo native Palpatine on the planet Chandrila ; Palpatine would later become Plagueis ' s Sith apprentice and take the name Darth Sidious . In 52 BBY , 11 - 4D was at Plagueis ' s side in the Fobosi District on the planet Coruscant while attending the initiation of the Muun Larsh Hill into the exclusive Order of the Canted Circle . There they survived an attack by Maladian assassins hired by the enemies Plagueis had made over the years by negatively affecting them with his plans . After transferring their base of operations from the island Aborah on Muunilinst to the moon of Sojourn , 11 - 4D continued to help Plagueis with his work . There , the Muun let Venamis , who had been in a comatose state since his capture , die in front of Palpatine and 11 - 4D , and then brought the Bith back to life via midi - chlorian manipulation , proving how far the Muun had come in his quest for immortality . In 33 BBY , Plagueis was once again targeted by his enemies , this time on Sojourn itself . 11 - 4D and Plagueis escaped in the starship " Scimitar " , moments before Plagueis ' s opponents devastated Sojourn with a nuclear bomb , obliterating the facility and the surrounding landscape . A year later , on the eve of the election of Palpatine , Naboo ' s incumbent Senator , to the office of Supreme Chancellor , the Senator killed his Master , leaving 11 - 4D under Palpatine ' s possession . Biography . Meeting the Sith . 11 - 4D , a masculine - programmed medical droid named after his model number , served in a medical facility on the planet Obroa - skai , where he performed research and conducted surgeries on a wide variety of species using his multiple appendages . 11 - 4D was eventually given to the Togruta Captain Ellin Lah as part of the payments owed to Lah by the medical facility , and although the exchange was meant to be temporary , Lah kept the droid , who served on her freighter , the " Woebegone " . The Togruta eventually retrofitted 11 - 4D ' s specialized medical appendages to more suit the tasks found on the ship . The crew of the " Woebegone " maintained a reputation in the Auril sector , and , in the year 67 BBY , 11 - 4D traveled with the freighter to the Auril sector ' s ocean world of Bal ' demnic from the planet Ord Mantell . The droid waited for the rest of the crew to return from the Kon ' meas Spaceport in the main cabin space of the " Woebegone " , which was being held in a refrigerated hangar after taking on a fresh cargo of sea life . Upon the other crew members ' return to the ship , 11 - 4D pronounced everything ship - worthy . Along with the Zabrak crew member Maa Kaap , 11 - 4D sealed the freighter before the " Woebegone " left Bal ' demnic and jumped to hyperspace , en route to the planet Ithor , located near Muunilinst . While they were completing the jump , the crew of the " Woebegone " discovered that they had a stowaway in Cargo Bay 4 . Five crew members went to confront the intruder : a Muun who , unbeknownst to the crew , was actually Hego Damask — Magister of the InterGalactic Banking Clan – allied financial group Damask Holdings , as well as the Sith Lord known to a select few as Darth Plagueis . The Sith had been stranded on Bal ' demnic after his starship was destroyed during a mission to the world , and had stowed away upon the freighter to maintain a low profile as he tried to get back to the Muun homeworld of Muunilinst . 11 - 4D monitored the crew ' s discussion in the main cabin about what to do with the stowaway . The droid noted that if the Muun ' s business on Bal ' demnic was going to adversely affect the planet , and it became known that the crew members of the " Woebegone " were the ones who brought him off - world , the crew might lose their reputation in the Auril sector . A decision was made : the " Woebegone " would drop out of hyperspace and contact the authorities on Bal ' demnic to see if the Muun was on the wanted list . If so , they would turn around to deliver the Muun to the authorities . Otherwise , they would negotiate a fee for taking the Muun to Ithor . As the freighter came out of hyperspace , the Sith Lord raced into the cabin area using Force speed and attacked the crew members with his lightsaber after giving them enough time to draw their blasters . In the resulting spray of blaster fire , 11 - 4D was only able to dodge the blaster bolts by using his ability to calculate their trajectories . Plagueis quickly dispatched the entire crew of the " Woebegone " save for 11 - 4D , whom the Sith all but ignored as he examined his victims . Plagueis then became 11 - 4D ' s master . After supplying 11 - 4D with new coordinates for the ship and forcing the droid to set the course , Plagueis also ordered 11 - 4D to prepare food and drink for him , as well as to tend to a wound that he had received on Bal ' demnic . Once the freighter reached its destination and came out of hyperspace , 11 - 4D responded to Plagueis ' s queries on how the droid became part of the " Woebegone " crew . 11 - 4D then transmitted a code provided by the Muun over the comm to Deep Space Demolition and Removal , the space station that the coordinates had taken them to . Accompanying the Sith Lord to the landing bay after docking , the droid raised the boarding ramp of the " Woebegone " and activated the anti - intrusion system to prevent others from boarding the ship and seeing the carnage aboard . As Plagueis met with a Nikto to have the " Woebegone " slagged , 11 - 4D was only saved from the same fate due to the fact that his memory storage could be erased according to the Muun ' s needs . 11 - 4D created an audio and video recording of the slagging of the " Woebegone " at Plagueis ' s request . Aborah . Upon arriving at Muunilinst ' s skyhook High Port Space Center from Deep Space Demolition , 11 - 4D and his new master were greeted by several Muuns led by the elderly Muun financier Larsh Hill at the High Port Immigration ' s customs control station . 11 - 4D accompanied Plagueis to his home on the island of Aborah by speeder , and he was escorted by the Sith on a tour of his retreat . As they got deeper into the dwelling , the pair came across Plagueis ' s workplace , which contained numerous test chambers and caged creatures . After being left to wander about the laboratories and galleries , 11 - 4D returned hours later to report to Plagueis . The droid inquired whether the data related to Plagueis ' s project would be available to upload , as the droid was unfamiliar with many of the things he had seen . Plagueis tasked him with scanning most of the data , starting with the history of the Sith , the sect to which he belonged that was comprised of Force - sensitives who utilized the dark side of the Force for their own benefit . Upon further inquiry , 11 - 4D discovered the purpose of the Sith Lord ' s project : to conquer death . Tracking the Force - sensitives . When 11 - 4D ' s master later returned from the moon of Sojourn , where he had been meeting with other influential members of the galaxy , Plagueis brought with him the young Bith Sith Lord Darth Venamis , whom he had defeated after the Bith had surprised and attacked him on Sojourn . Venamis was another apprentice of the Sith Lord Darth Tenebrous , Plagueis ' s Master , and had attacked the Muun in retaliation for Plagueis ' s killing of Tenebrous on Bal ' demnic . In one of Plagueis ' s laboratories , 11 - 4D , newly refitted with medical appendages , assessed the condition of the comatose Bith , who was suspended in a bacta tank . The droid found that the patient ' s physical state was stable . 11 - 4D and the Muun hacked into the databanks of the ship on which Venamis had traveled to Sojourn , which Plagueis had also brought to Muunilinst , where they found entries on six Force - sensitive beings whom Venamis had been monitoring as potential Sith apprentices . However , the droid soon discovered that three of the beings whom Venamis had hoped would protect the Grand Plan , a centuries - old plot by the Order of the Sith Lords to destroy the Galactic Republic and the Jedi Order , had died from various causes . After discovering the existence of the Force - sensitives , 11 - 4D and Plagueis set out to find them to ensure that none of them would be able to pose a threat to the Sith Lord . The first Force - sensitive , a Quarren who had used the Force to win a large sum of credits in gambling , was tracked to Colliders Casino on Lianna , in the Tion Cluster . With 11 - 4D ' s surgical appendages replaced with a pair of utility arms , he and Plagueis arrived at Colliders , where the Sullustan manager of the casino ferried them to a large office after being informed that the Muun was Magister of Damask Holdings . As Plagueis was inquiring about a massive winning streak the casino had seen recently , a Kubaz gambler hit a winning streak , prompting Plagueis to investigate . After Plagueis returned , he , 11 - 4D , and the manager viewed a databank containing images of gamblers whose winnings had heavily damaged multiple casinos ' earnings . As 11 - 4D and the Sith came out into the main section of the casino , 11 - 4D remarked that all of the gamblers , including the Quarren whom they were tracking , were 1 . 8 meters tall , even though they were of different sexes and species . The observation led the pair to conclude that the gamblers were actually one person : a changeling , and the individual whom Venamis had been following . 11 - 4D reasoned that the one they were searching for was a shapeshifting Shi ' ido , as the group of gamblers had a shapeshifting Clawdite among them , and Clawdites could rarely stay in an alternate form for long without experiencing discomfort . Almost immediately after this revelation , a Bothan informed them that the Kubaz was leaving the casino . 11 - 4D and his master pursued since Plagueis had sensed the Kubaz using the Force to cheat , suggesting that the gambler was in fact the Shi ' ido whom Venamis had unkowningly been tracking as the Quarren . 11 - 4D and Plagueis trailed the Kubaz across Lianna City , in which the casino was located , and after their mark entered a pedestrian tunnel , the two raced to get to the other end before the Kubaz emerged on the other side . The Kubaz never did ; rather , a burly Askajian appeared , an individual whom Plagueis correctly identified as the Shi ' ido in a new form . The pair followed the Askajian to an InterGalactic Banking Clan kiosk , where he deposited the credit chit that contained his winnings . After his departure , 11 - 4D and the Sith accessed the kiosk and acquired the account number and the name of its owner : Kerred Santhe the Second , the principal owner of Santhe / Sienar Technologies . The duo continued to track the Shi ' ido , who was still in Askajian form , overtaking him and waiting for him in a desolate stretch of the city . On the being ' s approach , 11 - 4D shot the Askajian in the base of the brain with a tightbeam fired from a laser weapon hidden in his right arm . In mid - shapeshift , the changeling reverted to his natural Shi ' ido form . 11 - 4D and Plagueis interrogated the shapeshifter and learned that Santhe was millions in debt to members of the Black Sun crime syndicate , and that the Shi ' ido , who was affiliated with Santhe , had been attempting to pay some of the debt off bit by bit to prevent Black Sun from going public with information about the financial troubles , which would most likely cause Santhe to be ousted from power by members of his company . Plagueis let the Shi ' ido go , as the being was not dangerous to the Sith and their plans , though the Shi ' ido lost the ability to shapeshift due to 11 - 4D ' s tightbeam attack . Plagueis later tracked Venamis ' s second Force - sensitive to the world of Saleucami , but left 11 - 4D on the planet Sy Myrth to maintain a lower profile . 11 - 4D and the Sith Lord tracked the third Force - sensitive , a Nautolan by the name of Naat Lare , to the Bedlam Institution for the Criminally Demented on the Mid Rim planet Bedlam , where Lare had been confined for five years . The Ithorian superintendent of the Bedlam Institution informed 11 - 4D and the Muun that the peculiar , gifted Nautolan had disappeared two months earlier , with the help of a Bith claiming to be a physician : Venamis . The pair also learned that the places to which Lare could have escaped were limited to the worlds of Felucia , Caluula , and Abraxin due to the small amount of starships leaving Bedlam . The Ithorian added that the Jedi Order had been informed of the disappearance because of Lare ' s gift with the Force . On their starship , 11 - 4D searched the HoloNet and other sources at Plagueis ' s request for events that might indicate that Lare was on one of the three worlds ; the droid soon found reports of the killings of non - sentient marsh haunt s on Abraxin . On that world , 11 - 4D and Plagueis came across a quartet of dead marsh haunts being hauled away by Barabel natives . They came to a Barabel settlement , where they met Jedi Master Ni - Cada and his Padawan Lo Bukk , who were investigating the killings on the suspicion that a Force - sensitive was to blame ; Plagueis claimed that he and 11 - 4D were on Abraxin to attend to a matter concerning micro - loans . 11 - 4D and the Muun spent the afternoon eavesdropping on conversations about the killings and concluded that Lare ' s work followed a pattern . Later that day , Plagueis lured Lare out into a confrontation with the Jedi , which resulted in the death of the Nautolan . Further service to Plagueis . During 11 - 4D ' s continued service to Plagueis , the Muun took an interest in the untapped plasma reserves on the world of Naboo , as well as in the young man Palpatine of the House of Palpatine , one of Naboo ' s royal families . 11 - 4D accompanied the Muun to Chandrila , where they surprised Palpatine with a visit in the Gladean State Parks outside of Hanna City while the youth was there as a member of the Legislative Youth Program . During the meeting , Palpatine expressed his anger at his father , and he also revealed that he had known the two would come for him , despite the fact that the visit was supposed to be a surprise . During the meeting , both 11 - 4D and Plagueis realized that the youth was highly Force - sensitive . 11 - 4D and Plagueis later returned to Aborah , where they continued the Muun ' s work on Venamis . 11 - 4D applied his expertise on the internal organs , while the Sith attempted to manipulate the Bith ' s midi - chlorians to extend Venamis ' s life . A communication from Palpatine interrupted 11 - 4D and Plagueis ' s work to inform them that the youth had killed his own parents using the Force in a fit of anger . 11 - 4D supplied Palpatine ' s location by request and accompanied a squad of Plagueis ' s Sun Guard s to help the young Naboo noble . A week later , Palpatine took the title Darth Sidious , becoming Plagueis ' s Sith apprentice as part of the Rule of Two , the guiding principle of the Sith that stated there would only be two Sith at a time : the Master and the apprentice . Over the next eleven years , 11 - 4D continued to watch over the suspended Venamis , and Plagueis collected numerous new test subjects from a wide range of species , including a lizard - like Yinchorri specimen . Although natural immunity to telepathy and other mind tricks helped the Yinchorri resist being compelled to pay obeisance to the Muun for two years , 11 - 4D witnessed firsthand as the Yinchorri finally broke and bowed to the Sith Lord ' s mastery . Assassination attempt . In 52 BBY , accompanied by 11 - 4D , Plagueis visited the Lodge of the Order of the Canted Circle on the galactic capital of Coruscant ' s Fobosi District in order to attend the initiation of Larsh Hill into the old and prestigious Order of the Canted Circle . Meanwhile , Palpatine , who had become the Senator for Naboo as he secretly worked for the Sith ' s interests in the Senate of the Galactic Republic , was kidnapped by forces sent by the Gran Senator Pax Teem and Santhe Security on Coruscant — Palpatine ' s relations with Plagueis ' s alter ego , Hego Damask , needled both parties , as his plans adversely affected them . After Palpatine was rescued by Plagueis ' s Sun Guards , Plagueis , with 11 - 4D standing beside him , contacted his apprentice via hologram from the Fobosi District . After sending a squad of Sun Guards to exact revenge on the Gran at the Panoply Orbital Facility , Plagueis soon returned to the matter at hand : Hill ' s initiation . During the ceremony , cloaked Maladian assassins hired by Teem and disguised as Canted Circle members attacked Plagueis and the Muuns attending the initiation . Throwing decapitator disk s , the assassins struck down numerous Muuns — including Hill — and wounded Plagueis in the neck . 11 - 4D was hit in more than three places and heavily damaged ; leaking lubricant , he still tried to reach his master . The droid came within a meter of Plagueis before being forced to take himself through a self - diagnosis routine due to damage dealt by five of the assassins ' disks . The Maladians continued their attack on Plagueis , who became severely wounded , before being cut down by Palpatine and his ally Sate Pestage with a repeating blaster , as the Muun ' s apprentice had sensed what was transpiring . Despite his damage , 11 - 4D managed to walk to the wounded Plagueis ' s side and treat his injuries . Palpatine later dealt with Teem , who was not at the Panoply Orbital Facility as they had believed , but instead at the Gran Protectorate Embassy , where the Sith killed him and his allies . The damage dealt to 11 - 4D was repaired , and , one month after the attack , 11 - 4D escorted Palpatine during his first visit to Aborah . The droid led Palpatine to the waiting Plagueis , who had been forced to wear a breath mask due to his injuries . Plagueis then outlined his plan to relocate all of his work and Sith - related objects to Sojourn , where he and 11 - 4D would now operate from Plagueis ' s residence there . Sojourn . In the time after the attack on Plagueis , 11 - 4D became a liaison between Plagueis and the Sun Guards , relaying his master ' s requests instead of the orders coming directly from Plagueis , as had been the case in the past . As twenty years passed by , many of Plagueis ' s test subjects died , while the once - grand residence on Sojourn slowly fell into shambles . Sometime around 34 BBY , 11 - 4D , along with Plagueis and Palpatine , viewed a holorecording of the Zabrak Darth Maul — a non – Rule of Two Sith apprentice of Palpatine — destroying combat droids for training . While Plagueis was still preoccupied with attempting to give life to Venamis , 11 - 4D reported to his master one day that the geological compressor from Plagueis had arrived on schedule at the prison Cog Hive Seven ; the geological compressor was a part of a plan to assassinate the reclusive weapons dealer Iram Radique , who operated out of the prison . The droid also informed the Sith Lord that the Muun Vesto Slipher from the IBC , whom Plagueis had sent to the prison to further his plans , had met his end at the hands of a CLL - series load lifter . By using the surveillance footage from the prison , 11 - 4D had been able to confirm that the droid that had decapitated Slipher had also been tasked with delivering the geological compressor to Maul , who was undercover as a prisoner in Cog Hive Seven . To answer the droid ' s question as to why Plagueis had interceded and secretly helped Maul by providing the Zabrak with the device , as Sidious had been tasked with seeing that the task was fulfilled , the Muun replied that it was to strengthen his and Sidious ' relationship , because the Human Sith Lord had been displaying too much self - reliance . Sometime afterward , Plagueis allowed the Bith Venamis to die after being kept in stasis for so long . A stunned 11 - 4D and Palpatine watched as Plagueis willed the midi - chlorians of Venamis back to life , only to let the Bith die again . Plagueis repeated this process until Venamis ' s organs gave out , and then left the Bith at peace . 11 - 4D later attended a meeting on Sojourn between his master and the Hutt crime lord Jabba Desilijic Tiure . 11 - 4D and the Muun were invited to visit Jabba ' s Palace on the world of Tatooine by the Hutt lord himself , and also learned that Komari Vosa , the former Padawan of the Jedi Knight Dooku , had become the leader of the Bando Gora cult , information that the Sith would later use to pressure Dooku to join the Sith ' s cause . Sometime during 33 BBY , 11 - 4D and Plagueis received warning from Jabba of an impending attack against the Muun Sith Lord on Sojourn at the hands of the current Monarch of Naboo , Ars Veruna , who owed his position to Plagueis ' s intervention , but had come to resent the Muun after Plagueis recently betrayed him by trying to get Veruna off the throne . 11 - 4D helped arrange the evacuation of the facility at Sojourn , making sure that all the data on the projects had been deleted , communicating Plagueis ' s orders to the Sun Guards , and carrying storage boxes to the courtyard . 11 - 4D returned to his master and informed him that the incoming attack fleet , comprised of five battleships , had arrived ahead of schedule . In the courtyard , the droid and Plagueis quickly boarded the " Scimitar " , a prototype starship equipped with a cloaking device . Cloaked , the " Scimitar " carried the duo away from the surface , which moments later was leveled by a nuclear bomb . The ship proceeded to Jabba ' s starship , the " Star Jewel " , which awaited them in the system . Back on Coruscant , 11 - 4D escorted Palpatine to Plagueis ' s study in the Kaldani Spires Residential Apartments , where the two Sith discussed how to exact revenge on Veruna and his allies . 11 - 4D accompanied Plagueis on his mission to deal with Veruna ; after Plagueis landed his starship near a castle in the Western Reaches of Naboo , where Veruna sought refuge , 11 - 4D remained in the cockpit of the craft as Plagueis exacted revenge and killed his enemy . Death of the master . In 32 BBY , the galaxy - spanning Trade Federation invaded the world of Naboo over a trade dispute — an event that was manipulated into fruition by both Plagueis and Palpatine to get the latter appointed Supreme Chancellor of the Republic . Soon after the invasion commenced , Plagueis and 11 - 4D watched from afar as Palpatine met with his apprentice , Maul , on a balcony on one of Coruscant ' s buildings . Palpatine tasked Maul with finding Queen Padmé Amidala , Veruna ' s successor as the ruler of Naboo , after she had managed to escape the blockade of her homeworld with the help of a small group of allies , including two Jedi . 11 - 4D relayed the conversation to Plagueis by using his auditory inputs . As per Plagueis ' s and Palpatine ' s plan , Amidala called for a Vote of No Confidence in the current Chancellor , Finis Valorum , so that Palpatine might be elected to the office of Supreme Chancellor . On the eve of that vote , 11 - 4D acted as a waiter during a discussion between Palpatine and Plagueis in the latter ' s penthouse at Kaldani Spires . Master and apprentice discussed the progress of the Sith Grand Plan and how Palpatine would take Damask as his co - chancellor , talking for most of the night . When Plagueis grew drunk from wine and fell asleep , the apprentice betrayed and murdered him , securing the power of the Senate for his sole command . 11 - 4D attempted to help the fallen Dark Lord , but the droid was halted from doing so by order of his new owner , who noted that the droid would need a new home and body . 11 - 4D shuffled in confusion at this turn of events . Characteristics . Description . A multi - appendaged bipedal droid , 11 - 4D was named after his model number and possessed masculine programming . Being a medical droid , 11 - 4D was classified as a first - degree droid . The droid ' s appendages could be retrofitted , which was done on numerous occasions : 11 - 4D ' s original surgical - suited appendages were retrofitted by Ellin Lah to serve the " Woebegone " tasks , before being returned to the original ones by his new Muun master , Darth Plagueis . On the trip to Lianna , 11 - 4D used a pair of broad - purpose utility arms that concealed a laser weapon in the right arm . At the time of the bombing of Sojourn , 11 - 4D possessed four arms . He had a round head and an alloy shell , and he was able to move at a speed that was considered fast for a droid . 11 - 4D had auditory sensors , which allowed him to hear better than most organics , including Plagueis , and he had olfactory sensors which could detect things such as the release of pheromones . 11 - 4D ' s photoreceptors could , upon adjusting the input rate , see subjects traveling at the heightened rate of Force speed , and at a distance farther away than an organic could . His photoreceptors made a whirring sound whenever they focused on something , and with them , he could make audio and video recordings . The droid ' s memory storage was modular in design , capable of being wiped completely or to the degree seen fit by his master . He was able to intake data by downloading or scanning . 11 - 4D had a large databank of information and had multiple listings under certain topics , although some references escaped his databank ' s capacities . The droid had the ability to calculate the trajectory of objects and to react instantaneously to danger , which helped him keep himself out of harm ' s way during the fighting on the " Woebegone " . 11 - 4D was able to take himself through a self - diagnosis check , a capacity he used to assess the damage dealt to him during the attack in the Fobosi District . Personality . 11 - 4D was very knowledgeable and skilled in the medical field . The droid had an advanced understanding of the physiology of many species , such as the Shi ' ido , Clawdites , and Pau ' ans . 11 - 4D later used his knowledge of shapeshifting species to identify as a Shi ' ido the first Force - sensitive whom Venamis had selected as a potential apprentice . The droid was also adept at performing surgeries , completing most of these while in the service of the Obroa - skai facility , although he did perform some while serving Darth Plagueis . 11 - 4D was able to diagnose certain medical traits and had experience in organ replacement surgery , telomere genotherapy , and carbonite suspension . As he was responsible for the well - being of the " Woebegone " crew , 11 - 4D created individual profiles for the crew based on details such as body temperature and breathing rates . He was able to tell that the Muun stowaway significantly elevated many of the crew ' s stress levels . 11 - 4D frequently eavesdropped on the crew ' s conversations in order to gauge their health . During his time under Plagueis , the droid looked after Venamis , one of Plagueis ' s most prized specimens , while the Bith was in his comatose state . Whenever Plagueis was injured , 11 - 4D was able to help his master with his medical capabilities , even in the Fobosi District when 11 - 4D was heavily damaged . 11 - 4D was able to pilot ships and prepare food and drink . When Plagueis replaced Ellin Lah as 11 - 4D ' s master , the droid immediately transitioned to become the Sith Lord ' s servant . 11 - 4D was loyal to Plagueis , accompanying him on many missions , and when the Muun was severely wounded by the Maladians , 11 - 4D attempted to help Plagueis in the midst of the attack . When Plagueis was killed by Palpatine , 11 - 4D tried to treat the Muun for his injuries , but was motioned not to by the Senator . Although he later addressed Palpatine as " master , " 11 - 4D shuffled in confusion at the change of ownership . Due to his time spent serving the Sith , 11 - 4D became knowledgeable about the Force and knew that if Plagueis attempted to contact Naat Lare on Abraxin via the Force , the Jedi there would most likely sense him . After Palpatine informed 11 - 4D and the Muun that he knew that they would come to Chandrila , 11 - 4D found it curious that his premonitions were correct . He also wished he could have a tool comparable to the Force . 11 - 4D sensed something was about to happen seconds before the attack in the Fobosi District . 11 - 4D was always polite to his owner , never failing to address his master by his or her proper title . The droid was a logical thinker , able to hypothesize very accurately about certain events , such as why the attack force sent at Sojourn had arrived early , which he speculated was because Plagueis ' s enemies had gotten wind of his knowledge of their imminent attack . 11 - 4D ' s speculations were deemed sound by Plagueis , a knowledgeable and powerful being . Before exiting the ship on Naboo prior to his murder of Veruna , Plagueis was comforted by the fact that 11 - 4D would anticipate resistance , as the Muun was currently doing . 11 - 4D never presumed to ask why Captain Lah kept the droid , and upon Plagueis ' s statement that such conduct was a good quality in a droid , 11 - 4D agreed . 11 - 4D , in the conversation that the crew of the " Woebegone " had on the matter of the Muun stowaway , pointed out how they might lose their reputation in the Auril sector if word got out that they had transported a Muun who had negatively affected Bal ' demnic off - world . During his time on Sojourn , 11 - 4D took to communicating Plagueis ' s orders and requests to the Sun Guards . When 11 - 4D was tasked with deleting the data on Sojourn , he made sure it was gone twice before doing so a third time after Plagueis asked it of him . In the moments leading up to the bombing , 11 - 4D took considerable charge in carrying out the evacuation , deleting the data , contacting the Sun Guards , and arranging for the " Scimitar " departure . Behind the scenes . 11 - 4D first appeared in 2012 ' s " Darth Plagueis " , written by author James Luceno . 11 - 4D was later mentioned in Pablo Hidalgo ' s " The Essential Reader ' s Companion " , released in 2012 , and also played a minor role in 2014 ' s " " , by Joe Schreiber . In a question session on Facebook , Luceno commented that 11 - 4D was present when Jedi Knight Anakin Skywalker was fitted with his armor as he became the Sith Lord Darth Vader , a scene from 2005 ' s . Luceno also stated that it was possible that 11 - 4D was one of the droids that ambushed the elite Republic squad Aurek Team as they neared Palpatine ' s secret lair on Coruscant , an event which happened in Luceno ' s own book , " Labyrinth of Evil " , also in 2005 . However , neither of Luceno ' s theories have been confirmed as canon . Despite " Darth Plagueis " more commonly referring to 11 - 4D as an " it , " this article assumes that the droid has masculine programming due to the book occasionally referring to it as a male .
