AZI - 345211896246498721347 AZI - 345211896246498721347 was a medical droid who served the Grand Army of the Republic during the Clone Wars . He was known as AZI - 3 by the ARC trooper " Fives , " who felt that numbers were demeaning . In 19 BBY , AZI - 3 struck an unlikely friendship with Fives as the two worked together to investigate a supposed " tumor " that had caused Fives ' fellow soldier Tup to assassinate the Jedi General Tiplar . During the course of their investigation , the two discovered that all Clone trooper s had been implanted with inhibitor chips for an unknown purpose ; which subsequently turned out to be Darth Sidious ' s planned Jedi Purge . Biography . An unlikely friendship . AZI - 3 served in the medical facility at Kamino ' s Tipoca City . He was present for the arrival of " Tup , " a clone trooper who was suffering from a mysterious condition that had caused him to attack and kill the Jedi General Tiplar . He was assigned to oversee testing on Fives , whom it was believed might have been exposed to whatever condition had affected Tup . Fives , wanting to help his friend Tup , used a wordplay to convince AZI - 3 that , by not helping the patient , he was doing the opposite of what he was programmed to . After convincing AZI - 3 to help him , Fives explained to the droid that no clone went by a number these days and his camaraderie with Tup . AZI - 3 suggested that they complete a Level 5 atomic brain scan on Tup but the Kaminoan doctor Nala Se refused on the grounds that a post - mortem dissection would yield the proper results . AZI - 3 and Fives were unaware that Nala was trying to conceal the existence of inhibitor chips in all Clone trooper s , which was central to Darth Sidious ' Order 66 . Continuing to work with Fives , AZI - 3 performed the procedure , eventually conducting a biopsy based on the readings , and discovered a mysterious " tumor " inside Tup . It transpired that the tumor was actually a control chip and when it was removed , Tup died . Shortly later , AZI - 3 and Fives were corned by Nala Se and Shaak Ti . Following an argument , Shaak Ti and Nala Se reached an agreement for the " tumor " to be transported to the Jedi Temple and then the Grand Republic Medical Facility for further analysis . Unmasking a conspiracy . Due to his role in helping Fives to defy his superiors ' orders , AZI - 3 was sent to have his memory wipe d in order to purge for his knowledge of these chips and malfunctioning . On the way , AZI - 3 casually informed Fives that the Clone trooper was to undergo a memory wipe as well and to be reassigned to sanitation duty . Realizing that the Kaminoans were trying to hide a conspiracy , Fives broke free of his captors and fled the medical suit with AZI - 3 in tow . The two stole a Kaminoan flight pod from a hangar and fled into the skies above Tipoca City . Fives then informed AZI - 3 that his plan was to use the flight pod ' s autopilot to distract the Kaminoan security forces while he and AZI - 3 returned to the clone laboratories to continue their investigation into the " tumors " . Fives flung AZI - 3 into the sea before jumping in as well . AZI - 3 then revealed that he could reconfigure his body into an improvised hover mode . AZI - 3 and Fives then re - entered Tipoca City through a service hatch . Under Five ' s orders , AZI - 3 lured another Clone trooper into the service area so that Fives could knock him unconscious and steal his armor . The two then made their way to Kamino ' s Genetic Records Hall where AZI - 3 compared to the tumor ' s DNA to that of the late Jango Fett , who had been the Clone troopers ' genetic template . The scan confirmed that the " tumor " did not match Fett ' s genotype and that it was an organic chip that had been implanted into Tup . After Nala Se learned of their presence , AZI - 3 and Fives escaped Shaak Ti and several Clone troopers through a ceiling hatch . While crawling through the service tunnels , AZI - 3 speculated that the chip had an unknown purpose . Fives convinced AZI - 3 to operate on him in order to investigate whether he too had the implant . After finding a sterile room , AZI - 3 operated on Fives and found a healthy chip inside his head . The two then headed to the embryo room . On the way , they passed through a training room and AZI - 3 tried to distract the Kaminoan instructors by singing . After entering the embryo room , AZI - 3 and Fives discovered that all of the Clone embryos had been implanted with the chips at the third stage of their development . The two fugitives were soon cornered by Shaak Ti , Nala Se , and several Clone troopers . Nala Se wanted to destroy Fives on the grounds that he was an " aberrant " Clone who was Kaminoan property . However , Shaak Ti insisted that the clones were the property of the Galactic Republic and convinced Nala Se to allow Fives and the chips to be presented to Supreme Chancellor Palpatine , who was secretly Darth Sidious . AZI - 3 expressed jubilation that he had helped Fives prove his case to Nala Se and Shaak Ti . He escorted Fives to a transport that took him to the galactic capital Coruscant . Despite the efforts of AZI - 3 and Fives , Darth Sidious and his Sith apprentice Darth Tyrannus successfully conspired to prevent AZI - 3 from revealing the existence of the inhibitor chips to the wider public . The concealed Clone inhibitor chips would play an important role in advancing Darth Sidious ' Jedi Purge at the end of the Clone Wars . Characteristics .

AZI - 3 displayed considerable bravery and loyalty to his unlikely friend Fives during the course of their mission . AZI - 3 ' knowledge of the Tipoca City cloning facilities enabled him to help Fives discover that all Clone troopers were implanted with inhibitor chips for an unknown purpose , later revealed to be Order 66 .
