AP - 5 AP - 5 was a masculine RA - 7 protocol droid who served as an analyst droid on a Galactic Republic attack cruiser during the Clone Wars . At the end of the conflict , the Republic was replaced by the Galactic Empire , and AP - 5 was relegated to inventory duty aboard the cargo transport 241 , an Imperial cargo ship . In the third year before the Battle of Yavin , AP - 5 encountered the astromech droid Chopper when the latter hid in the cargo ship while evading several pursuing stormtrooper s . Tired of being mistreated , the inventory droid befriended Chopper , helping him steal the cargo ship and providing his rebel allies with a suitable location for a secret base . After joining the rebellion , AP - 5 continued working as an inventory droid for the Phoenix Cell at Chopper Base on the planet Atollon . Despite his grumpy and sarcastic personality , AP - 5 remained loyal to his new rebel masters . During a mission on Wynkahthu , AP - 5 played an indispensable role in helping the Spectres to recover cargo from a derelict Imperial cargo ship . Later , AP - 5 along with the Lasat warrior Garazeb Orrelios and Chopper helped to stop the E - XD infiltrator droid EXD - 9 from reporting their base ' s location to the Empire . Biography . Early existence . An RA - 7 protocol droid with masculine programming , AP - 5 was activated at some point before the fall of the Galactic Republic . During the pan - galactic Clone Wars that pitted the Republic against the Confederacy of Independent Systems , AP - 5 served as a navigator and a military analyst aboard a " Venator " - class Star Destroyer . He notably participated in the Ryloth campaign , in which he estimated the Republic ' s tactical strategies were only 70 % effective . Although the Republic ended up winning the campaign , AP - 5 ' s commander did not survive . Age of the Empire . Fall of the Republic . At the end of the Clone Wars , the leader of the Republic , Supreme Chancellor Sheev Palpatine , unilaterally abolished the regime , transforming it into an authoritarian Galactic Empire . Although AP - 5 had been , according to himself , the best Republic navigator in his class , he was downgraded and reassigned to inventory duty aboard the cargo transport 241 , an Imperial class four container transport . The rebellion . Joining Phoenix Squadron . In the third year before the Battle of Yavin , AP - 5 encountered Chopper , a feisty astromech droid who belonged to a group of rebels called the Spectres . The astromech had been separated from his rebel cell and stranded on Horizon Base , where the cargo transport 241 was docked at the time . Looking for a safe haven from the Imperial stormtrooper s , Chopper had boarded the cargo ship . During a ship - wide search for the stowaway , AP - 5 did not report Chopper ' s presence to his Imperial superiors , gaining the latter ' s trust and developing a friendship by telling war stories . When the ship ' s abusive Imperial captain belittled AP - 5 , Chopper sprung to his defense and managed to knock out the captain . The two droids then joined forces to seize control of the ship . Later on , AP - 5 aided the rebellion by warning the rebels that the Yost system , their original jump destination , was not safe because an Imperial fleet had already been dispatched there . He instead provided the coordinates of an alternative world called Atollon which lacked any Imperial presence , making it a more suitable location to plant a rebel base . While transmitting the coordinates to the new system , AP - 5 was shot twice by the ship ' s captain , who had regained consciousness . The inventory droid sustained serious damages , but , before he shut down , AP - 5 managed to tell Chopper that he would not forget their friendship . Fortunately , after the two droids rendezvoused with the rest of the Phoenix Cell rejoined the crew of the " Ghost " , Sabine Wren managed to repair AP - 5 , using some parts disassembled from Chopper ' s stolen ambulatory strut . Immediately upon being restored to working order , AP - 5 chided Chopper for not thinking logically , prompting Chopper to reply with a string of expletives . AP - 5 retaliated by saying that the words were so foul that the droid would be disintegrated in six systems . Using AP - 5 ' s information , the Phoenix Cell was able to establish a new base on Atollon called Chopper Base . AP - 5 was placed in charge of checking the cargo that arrived from the base . Used to working with the Empire , AP - 5 was unhappy with the frequent delays in rebel shipments arriving at Chopper Base . When the crew of the " Ghost " arrived with a shipment of power generators , AP - 5 complained that the shipment was already several hours overdue . AP - 5 then asked his friend Chopper whether it was routine for rebel shipments to be late ; to which the droid answered in the affirmative . Homecoming party . AP - 5 was later part of a homecoming party that greeted Kanan , Ezra , and Chopper after they returned from their perilous mission to Malachor . He and the Spectres , and the former Clone Captain Rex witnessed a blinded Kanan hugging Hera while Ezra exited the starship " Phantom " without former Jedi Padawan Ahsoka Tano , who Ezra and Kanan believed had perished on Malachor . Rescuing defectors . After the Phoenix Squadron received word that a group of Imperial cadet s from the elite Skystrike Academy were planning to defect to the rebellion , AP - 5 was tasked with preparing fake credentials for Sabine ' s infiltration mission . Mission to Wynkahthu . Later , AP - 5 lent his expertise to a mission undertaken by the crew of the " Ghost " , the pirate Hondo Ohnaka , and the crime lord Azmorigan to steal cargo from an Imperial cargo ship that had become trapped in the atmospheric storms in Wynkahthu ' s upper atmosphere . Due to his experience working aboard a class four container vessel , AP - 5 was able to advise the Lasat warrior Garazeb Orrelios when planning the mission . AP - 5 and Zeb ' s planned involved jumping onto the hull of the ship , restarting its power plant , and then opening the cargo ramp doors to evacuate the cargo with grappling guns . AP - 5 calculated that the mission had a 38 . 5 % chance of success . When Kanan protested , AP - 5 responded that they would have a zero percent chance without him . AP - 5 stayed with Hera and Kanan aboard the " Ghost " while the other rebels , Hondo , and Azmorigan boarded the ship . Despite his careful planning , AP - 5 overlooked the fact that restarting the power generator reactivated one of the Imperial sentry droid s . The sentry droid attacked Azmorigan and Zeb and locked them in the brig . When Zeb contacted the " Ghost " , AP - 5 apologized for his mistake and warned the rebels not to engage the droids . Despite his warning , Azmorigan destroyed one of the droids . This triggered the other sentry droids which attacked the rebels and their confederates . However , they managed to escape the cargo ship before it collided with the vortex and exploded . AP - 5 stayed aboard while the rebels celebrated their catch of proton bomb s and Hondo and Azmorigan left with their Ugnaught crew member Melch with their " treasure . " Strike on Lothal . After Hera briefed Phoenix Squadron on a planned strike against the Imperial Armory Complex on the planet Lothal , AP - 5 began loading explosives aboard the rebel freighter " Ghost " . While he was chatting with his friend Chopper , Sabine arrived with the second load of explosives . Despite AP - 5 ' s protestations that they had enough , Sabine insisted on loading more and stressed that she was the weapons expert . AP - 5 grumbled about the changes to the supply schedule but compiled with Sabine ' s orders . When Sabine remarked that AP - 5 and Chopper came from the same supply line , Chopper remarked that she needed an attitude adjustment . Defending Chopper Base . Later , AP - 5 along with Chopper , the Lasat warrior Captain Garazeb Orrelios , and communications officer stayed behind to guard Chopper Base while the other Spectres and Phoenix rebels departed for a training exercise . AP - 5 took advantage of the training exercise to commence a thorough inventory of the base ' s munitions depot . AP - 5 tried to solicit Zeb and Chopper ' s help but the two were not interested in such mundane work . When Zeb remarked that he did not regard counting crates as fun , AP - 5 quipped about teaching the Lasat how to read . Zeb and Chopper then headed to the command center . Later , AP - 5 caught them leaving and tried to solicit their help unsuccessfully . That evening , AP - 5 was lamenting the disorganized state of the depot when Zeb and Chopper arrived with a protocol droid they had found on the outskirts of Chopper Base . Zeb had taken pity on the " stray " droid and got AP - 5 to charge up the droid . Due to the emergency protocol , the protocol droid began to revive quickly and started scanning its surroundings including the depot , Zeb , and Chopper . Impressed , AP - 5 decided to take on the stray droid as his inventory assistant . Unknown to the rebels , the protocol droid was actually an E - XD infiltrator droid designated EXD - 9 ; which had been dispatched by Grand Admiral Thrawn to probe the Outer Rim Territories for rebel bases . Later , AP - 5 and Chopper took the protocol droid on a tour of the depot . At that point , Zeb arrived to warn AP - 5 and Chopper that the protocol droid was actually an Imperial Infiltrator Droid . Upon hearing the word " rebels , " EXD - 9 assumed his " attack mode " and attacked the rebels . EXD - 9 fought with Zeb , who managed to severe the droid ' s left hand following a fierce struggle . When AP - 5 suggested contacting Hera , Zeb refused because they did not have enough time and vowed not to fail the rebel leader . After finding a wrecked astromech droid that had been drained of its power and stripped of its spare parts , AP - 5 cautioned that Chopper was unable to track down the Infiltrator Droid because it was low on power . The three rebels then discussed their plan to capture and disable the Imperial droid . During the discussion , AP - 5 advised Zeb against using his bo - rifle since they were in a munitions storehouse . In the end , Zeb agreed to disable the droid and AP - 5 volunteered to help him do so . After Chopper lured EXD - 9 out of hiding , Zeb attacked the Infiltrator Droid . Following a fierce struggle , Zeb managed to pin down EXD - 9 and AP - 5 managed to deactivate him with considerable difficulty . After subduing the intruder , Zeb asked AP - 5 about the good news . AP - 5 reported that he could not detect any long - range transmissions which meant that EXD - 9 had not been able to contact the Empire . When Zeb asked about the bad news , AP - 5 informed the Lasat that EXD - 9 had activated his self - destruct mechanism . Chopper managed to freeze the droid ' s timer before it could detonate its proton warhead . Following a discussion with Zeb and Chopper , the rebels decided to send the Infiltrator Droid back to the Empire but with its proton warhead rigged to explode . As part of the plan , AP - 5 reprogrammed EXD - 9 to its protocol mode and timed the detonator to explode when it connected with the Imperial network . AP - 5 then followed Zeb and Chopper as they tracked EXD - 9 back to his pod . After Zeb shot EXD - 9 ' s long - range transmitter , the trio watched as EXD - 9 ' s pod departed into space . AP - 5 then began expressing doubts that he had reprogrammed the droid correctly . However , Zeb reassured AP - 5 that he done his great job . Despite not being on good terms , AP - 5 commended Zeb for his admirable work . In the end , AP - 5 ' s plan worked and the rigged EXD - 9 destroyed an Imperial Star Destroyer and several other Infiltrator Droids . However , Thrawn was still able to narrow down the search to 94 systems . The following day , AP - 5 accompanied Zeb and Chopper as they met up with the other Spectres . When Hera asked what happened , AP - 5 claimed he had nothing to do with it ; prompting a question from Kanan Jarrus . At the command center , the rebels were contacted by the rebel source Fulcrum , who commended them for reprogramming the Infiltrator Droid and setting it off to self - destruct . This rebel source was the disillusioned Imperial Security Bureau Agent Kallus , who had earlier befriended Zeb . When AP - 5 began to recount the story , Zeb playfully muffled him while the other Spectres watched in bemusement . Rescuing Kallus . After the rebels discovered that the Empire was monitoring Agent Kallus ' Fulcrum transmissions , AP - 5 accompanied his friend Chopper and Ezra Bridger on a mission to rescue Kallus , who was stationed aboard Lieutenant Yogar Lyste ' s " Arquitens " - class command cruiser . The rebels ' plan involved the droids and Ezra stealing a Star Commuter 2000 shuttle from the planet Lothal ' s Capital City spaceport . The rebels would then purposely allow their ship to be captured by Lyste and Kallus ' light cruiser . The plan worked and Ezra was captured . AP - 5 and a disguised Chopper managed to avoid capture by claiming they were unwilling passengers aboard the stolen shuttle . The rebels ' rescue mission was complicated when Grand Admiral Thrawn requested an audience with Kallus and Lyste aboard his Imperial Star Destroyer " Chimaera " . Lyste insisted on taking Ezra to showcase his success to the Grand Admiral . AP - 5 and Chopper managed to convince Lyste to bring them aboard by claiming that Chopper had film footage to use as testimony against Ezra , who claimed to be a bounty hunter . Once aboard the " Chimaera " , Chopper alerted the retrieval team members to the change in plans . Kanan instructed Chopper and AP - 5 to obtain a new set of clearance codes that would allow them to land on the " Chimaera " . AP - 5 then told the astromech droid that they could only obtain clearance codes from an officer ' s port . The two droids then argued about whether to rescue Ezra first or to steal the clearance codes . Agent Kallus resolved that argument by freeing Ezra from his cell . After Kallus informed Ezra and the droids that Thrawn was close to locating Chopper Base , AP - 5 convinced Ezra and the others to infiltrate Thrawn ' s office in order to steal the clearance codes . While AP - 5 served as a look - out , the other rebels and Kallus infiltrated Thrawn ' s Office and completed their objectives . AP - 5 witnessed Thrawn and another stormtrooper sentry returning to his office but failed to stop them from reaching the door . Kallus managed to distract Thrawn by reprogramming his Imperial sentry droid s into assassins , giving the rebels enough time to escape to the hangar . Following a brief scuffle between Kanan , Rex , Lieutenant Lyste , and Governor Arihnda Pryce , AP - 5 and his rebel comrades managed to escape aboard Kanan and Rex ' s " Sentinel " - class landing craft . Kallus opted to stay behind in order to continue feeding information to the rebels and framed Lyste as Fulcrum . However , Thrawn quickly discovered his deception but allowed Kallus to remain undetected in order to find the rebel base . Mon Mothma ' s speech . AP - 5 along with Commander Jun Sato and the former Clone Captain Rex were present at the Chopper Base command room when the former Imperial Senator Mon Mothma gave a live HoloNet broadcast urging the galaxy to rise up in rebellion against the Empire . Alliance to Restore the Republic . Saving Chopper from himself . After the formation of the Rebel Alliance , AP - 5 was given a mission by Phoenix Leader Hera Syndulla to steal clearance codes from the Imperial Security Bureau station on Killun 71 . These clearance codes were needed by the Phoenix Squadron as part of their upcoming raid on Lothal . For that mission , AP - 5 was accompanied by his friend Chopper and the rebel pilot Wedge Antilles , who had recently defected from the Empire to the rebellion . During the mission , AP - 5 argued with Chopper , who was jealous that the former inventory droid had been allocated the mission . AP - 5 was unapologetic and insisted that he would make a better spy due to his programming . This bickering annoyed Wedge , who quickly realized why the other Spectres had not volunteered for the mission . After landing at Killun Station , AP - 5 and Chopper disembarked from their stolen " Sentinel " - class landing craft . The two droids proceeded without incident through an Imperial sensor but Chopper ' s presence was detected by the crew of an Imperial IGV - 55 surveillance vessel . After some haggling with Chopper , AP - 5 proceeded to the base ' s central computer core alone . There , he was confronted by a female RA - 7 protocol droid called PZ - 7 , who inquired about his presence . AP - 5 tartly told her that she had been reassigned to inventory duty and that he was her replacement . AP - 5 then easily acquired the clearance codes and found Chopper motionless at a network terminal . AP - 5 thought Chopper was sulking and returned to the " Sentinel " shuttle first . In fact , Chopper had been remotely reprogrammed by the Imperial intelligence officers aboard the surveillance vessel . These Imperials wanted to use Chopper to steal the coordinates of Chopper Base . When Chopper rejoined them , AP - 5 realized that his friend was acting suspiciously . AP - 5 realized that Chopper was speaking in Imperial Code 16 . However , Wedge did not share AP - 5 ' s concerns and welcomed Chopper ' s more pliable nature . AP - 5 tried to warn Antilles while the latter was using the refresher but Wedge thought that the protocol droid was being childish and dabbling in conspiracy theories . Unknown to AP - 5 , the Imperial surveillance crew were watching his interaction through Chopper ' s visual processor . Their controller LT - 319 dismissed AP - 5 as a threat on the grounds that the protocol droid had undermined his own credibility . Back aboard the " Ghost " , AP - 5 ' s warnings were initially greeted by deaf ears . However , Hera validated AP - 5 ' s warnings after she stopped Chopper from downloading the " Ghost " hyperspace logs . Before they could check Chopper , the reprogrammed astromech droid brought the " Ghost " out of hyperspace . When the rebels headed to the engine room to confront Chopper , AP - 5 questioned the wisdom of everyone going to the same place . However , Ezra accused him of cowardice and AP - 5 was compelled to follow the group . Chopper then trapped the rebels in the ship ' s cargo bay and attempted to expose them to zero gravity space . After Hera had secured the cargo hold , she dispatched AP - 5 outside of the ship in order to open the entrance to the hold from outside . AP - 5 used his metallic body to navigate through the " Ghost " hull and reach the maintenance hatch outside . Despite being spotted and attacked by Chopper with blaster s , AP - 5 managed to open the entrance to the cargo hold . Chopper returned for a second loop and pushed him into space . While AP - 5 was left floating in space , the other Spectres managed to reprogram Chopper and neutralize the Imperial threat by reversing the data feed back to their ship , destroying the surveillance vessel from afar . While floating in space , AP - 5 reflected that he should be frightened but that he was strangely calm . As the protocol droid embraced the solitude of silence , he was surrounded by a herd of baby neebray . AP - 5 befriended them and began to break into a song . However , his moment of solitude was interrupted by the return of the " Ghost " . Despite his rescue , AP - 5 was upset that his solitude had been disturbed . Unaware of the earlier events , AP - 5 thought that Chopper was still compromised . This prompted the exasperated astromech droid to slap him and Wedge in the legs . Ezra ' s errant mission . After hearing from Kanan Jarrus ' holocron and the Sith holocron that the former Sith apprentice Maul was planning to kill Jedi Master Obi - Wan Kenobi , Ezra produced a faux manifest purportedly from AP - 5 delivering munitions to Phoenix Squadron ' s A - wing fighters . The rebel trooper guarding the airfield was distracted long enough for Ezra to borrow an RZ - 1T trainer and travel to Tatooine to find Kenobi . Battle of Atollon . During the Battle of Atollon , AP - 5 reported that scanners had picked up Imperial walker s approaching the western quadrant of Chopper Base . Shortly later , the remnants of Phoenix Squadron and General Jan Dodonna ' s Massassi Group fought against Grand Admiral Thrawn ' s ground forces before retreating into space . AP - 5 and the other rebels were surrounded by Thrawn ' s death trooper s before they could flee aboard the " Ghost " . However , an enigmatic being known as Bendu summoned a storm which gave the rebels a window to escape . After the rebel forces had reached space , AP - 5 recommended doing a double hyperspace jump in order to cover their tracks . The former Clone Captain Rex recommended a third and the rebels traveled to Yavin 4 . Characteristics . AP - 5 had a grumpy and pessimistic personality due to his exploitative treatment at the hands of his Imperial superiors . AP - 5 prided his service as an analyst droid during the Ryloth campaign and deeply resented being relegated to inventory work under the Galactic Empire . AP - 5 had an antagonistic relationship with his Imperial captain , who believed that he was destined for the scrap heap . AP - 5 found an unlikely friend in the form of Chopper , an astromech droid who was part of the rebellion . AP - 5 gained Chopper ' s trust and friendship after he removed his restraining bolt ; giving AP - 5 the will to defy his master . Despite his friendship with Chopper , AP - 5 could still be abrupt and condescending to his friend when he berated Chopper for committing the " illogical act " of sacrificing his stolen ambulatory strut to repair him . Despite only knowing the Rebels for a short time , AP - 5 has already formed an attachment to them , as he seemed saddened to learn of Ahsoka Tano ' s apparent death . Using his knowledge of Class four container vessels , AP - 5 helped the Lothal rebels plan their operation to steal cargo from an Imperial cargo ship . While he was a skilled planner , he was a calculating pessimist who believed that their mission had little chance of success . He also overlooked the presence of sentinel droids aboard the cargo ship and tried in vain to advice the recovery team not to provoke hostilities with the droids . AP - 5 was a rigid stickler to the schedule and grumbled when Sabine once insisted on loading more explosives . Due to their similar personalities , Chopper and AP - 5 got on well . This led Sabine to once remark that the two droids came from the same supply schedule . AP - 5 initially did not get on well with the Lasat Garazeb Orrelios and regarded him as a heavy - lifting grunt . AP - 5 could also be caustic towards Zeb and once joked about teaching him how to count . In return , Zeb found AP - 5 ' s attention to detail fastidious and long - winded . Later , AP - 5 gained a better appraisal of Zeb after witnessing the Lasat ' s combat prowess against the E - XD infiltrator droid EXD - 9 . AP - 5 displayed team spirit when he helped Ezra and Chopper during a mission to rescue Agent Kallus . AP - 5 managed to fool several stormtroopers and Lieutenant Lyste into believing that he and Chopper were unwilling passengers aboard Ezra ' s stolen shuttle . The Imperials did not suspect AP - 5 ' s deception since he was still in the livery of an RA - 7 protocol droid . AP - 5 used his knowledge of Imperial starships and procedures to help the rebels obtain a new set of clearance codes that allowed Kanan and Rex ' s landing craft to land on Grand Admiral Thrawn ' s flagship " Chimaera " . AP - 5 at times could be arrogant and condescending even to his friend Chopper . He once took pride with the fact that he had been assigned by Hera to steal a set of clearance codes from the Empire and took offense that Chopper should be upset . AP - 5 annoyed Wedge Antilles by his acidic nature and attention to detail . AP - 5 used his guile to convince the inventory droid PZ - 7 that he was her replacement and mocked her for believing his ruse . As a rebel agent , AP - 5 was a perfectionist who was meticulous with his work . Due to his knowledge of Imperial protocol and his observation skills , AP - 5 was one of the first to realize that Chopper had been compromised by the Empire . AP - 5 found his moment of solitude with space and befriended a herd of baby neebray . He was upset that his moment of solitude was disturbed by his rescue at the hands of his fellow " Ghost " crew . AP - 5 was also slow to forgive Chopper for the actions he had committed under his Imperial reprogramming and opined that he was still compromised . This prompted an angry outburst from the exasperated Chopper , who had been through a rough day . Equipment . As an RA - 7 protocol droid , AP - 5 had an insectoid head and a blue metallic body . He had a masculine programming and served as an analyst droid for the Republic and later as an inventory droid for the Empire . Due to his position , he was aware about Imperial fleet movements and star charts . AP - 5 used this knowledge to help the rebellion to find a safe haven on Atollon . As an inventory droid , AP - 5 was fastidious when it came to details . He also knew how to operate machinery , charge up , and reprogram other droids . AP - 5 was also an ingenious tactician who conceived a plan to conceal Chopper Base from the Empire by sending a bomb - rigged EXD - 9 to blow up a Star Destroyer . As a former Imperial droid , AP - 5 was familiar with the layout of Imperial ships and knew how to obtain clearance codes . Due to his mechanical body , AP - 5 was capable of surviving zero gravity space . His metallic body could also double as a magnet for climbing on ships in space . Behind the scenes . AP - 5 is voiced by Stephen Stanton , who based his portrayal on the late British actor . He is named after producer Athena Yvette Portillo , and his name also references her height . According to brand manager Pablo Hidalgo , AP - 5 left the Empire because they were going to turn him into scrap . Despite joining the rebels , he chaffed under their chaotic and disorganized state due to his love for cataloging items and structure . AP - 5 ' s actor Stanton also confirmed during an interview with Andi Gutierrez on Rebels Recon that they had included AP - 5 ' s singing moment as part of the script for " Double Agent Droid . " Show director Dave Filoni clarified that AP - 5 ' s encounter with the neebray s and song was intended to give a light - hearted ending to a filler episode .
