Unidentified Imperial cargo ship captain During the early rebellion against the Galactic Empire , an Imperial captain commanded a cargo ship that docked at Horizon Base . After departing , the rebel astromech droid Chopper inadvertently stowed away and took over the ship with the help of an inventory droid , AP - 5 , who served under the captain and was treated with disrespect . The captain attempted to stop the droids from bringing the ship to the rebellion , but he failed to end their plot . Biography . This Imperial captain commanded the class four container transport cargo transport 241 about three years before the Battle of Yavin . He was assisted by the inventory droid known as AP - 5 , a veteran of the Clone Wars who had served as an analyst droid during the Ryloth campaign . The Imperial captain regularly belittled AP - 5 , whom he believed was destined for the scrap heap . On one trip , he docked at Horizon Base to pick up a shipment of supplies . His visit to Horizon Base coincided with a heist staged by the Spectres , who had come to steal fuel for the Phoenix Cell . As the cargo ship was leaving Horizon Base , the rebel astromech droid C1 - 10P ( " Chopper " ) , who had been left behind after being distracted by stealing an ambulatory strut , managed to stow aboard the transport while fleeing several stormtrooper s . As Cargo transport 241 was preparing to depart into space , AP - 5 told him that he was off by . 0002 . The captain angrily responded that AP - 5 was a " useless droid " and ordered him to go and check the ship ' s cargo manifest . While AP - 5 went to check the manifest , the captain stayed aboard the ship ' s bridge . Meanwhile , AP - 5 encountered the stowaway Chopper . Following a pursuit , the two droids managed to befriend each other by their shared experiences of the Clone Wars . Chopper also managed to win AP - 5 over by contrasting his respectful relationship with his owner Hera Syndulla to AP - 5 ' s unpleasant servitude under the Empire . While the two droids were still conversing , the captain contacted AP - 5 via comlink and demanded that the analyst droid check the cargo manifest . The captain also warned AP - 5 about the stowaway . Unhappy with AP - 5 ' s progress , the captain went to find the inventory droid . Upon seeing AP - 5 , the captain chastised him for his tardiness in checking the cargo manifest while asking him about the stowaway . The captain then noticed that AP - 5 ' s restraining bolt was missing and attempt to apply a new one . However , Chopper then reappeared and attacked the captain . The captain fought back and called for reinforcements through his comlink . Despite his bigger size , Chopper managed to defeat the captain by stun ning him unconscious with his electro - shock prod . In the captain ' s absence , the two droids managed to hijack the cargo ship by driving the stormtroopers into the cargo compartment and detaching it in space . Chopper also changed course and decided to reunite with the rest of the rebel fleet , who were preparing to travel to the Yost system . The captain awoke while Chopper and AP - 5 were conversing with Hera , who was a leader in the Phoenix Group . AP - 5 had alerted the rebels that the Empire had set a trap in the Yost system . He was about to relay the coordinates for an alternative safe world when the Captain entered the bridge to confront the hijackers . Taken by surprise , AP - 5 tried to bluff the captain by claiming that he had been taken hostage . However , the captain saw through his deception and proceeded to attack the two droids . While AP - 5 manned the helm , Chooper fought with the captain and managed to knock out his gun . The captain used his bigger size to push the smaller astromech droid into a corner . He also used his blaster to shoot AP - 5 twice , badly damaging the droid . An enraged Chopped then fought back and managed to push the captain to the floor , knocking him unconscious . Chopper then relayed the coordinates to Hera before attending to AP - 5 and taking the ship to the alternative safe world , which was later revealed to be the planet Atollon . There , the Imperial captain was presumably taken into custody by rebel forces . Personality and traits . The Imperial captain was a broad - chested Human male with thick eyebrows , green eyes , and a big moustache . He had dark brown hair and a receding hairline . The captain was a mean - spirited bully who frequently belittled and chastised his cargo ship ' s inventory droid AP - 5 . On one occasion , he told the droid that he was destined for the " scrap heap . " His harsh treatment of AP - 5 convinced the droid to assist the rebel droid Chopper and aid the rebellion with information about Atollon . The Imperial captain was able to use his big build and size to intimidate smaller opponents like the astromech droid Chopper . However , he was unable to match the droid ' s wit and electro - shock prod . Behind the scenes . The Imperial cargo captain appeared in " The Forgotten Droid , " an episode in the second season of the animated television series " Star Wars Rebels " . He was voiced by James Adomian .
