Early life . A Mandalorian warrior and artist who lived during the Age of the Empire , Ketsu Onyo studied with her friend Sabine Wren at the Imperial Academy on Mandalore . At some point , they decided to escape the Academy , Ketsu helped her friend escape from the academy and the two became bounty hunter s . However , Wren alleged that Ketsu became " greedy " and left her for dead while she alone joined Black Sun . Meanwhile , Sabine survived and joined a group of rebels that operated from the starship " Ghost " and was part of a larger rebellion against the Galactic Empire . Repairing a Friendship . Several years later , Ketsu crossed paths with her former friend Sabine on the planet Garel . Onyo had been sent by Black Sun to collect the GNK - series power droid EG - 86 , who was carrying information of vital importance to the rebellion . The droid was scheduled to arrive on a GX1 short hauler at Garel City ' s spaceport . However , Ketsu ' s mission was complicated when she discovered that Sabine and two rebel associates , the astromech droid C1 - 10P and the human Jedi Padawan Ezra Bridger , had already picked up the courier droid . Shortly after , Ketsu emerged from hiding and confronted Sabine . After a tense reunion , Ketsu demanded that Sabine and her friends surrender EG - 86 . She also told Sabine that she would have been better off dead rather than joining the rebellion since the Empire had put a bounty on Sabine ' s head . Wren refused to back down and the two former friends prepared for a showdown . However , their confrontation was interrupted by the arrival of a stormtrooper patrol . When the stormtroopers demanded that they leave the spaceport , Onyo opened fire on the stormtroopers with her blaster ; sparking a three - way gun battle . In the midst of the fighting , Sabine and her rebel associates managed to escape with EG - 86 on a stolen shuttle . However , one of the rebels , Ezra , was separated from his comrades after falling out of the side entryway . Ketsu was then surrounded by stormtrooper reinforcements who held her at gunpoint . However , she turned the tables on them and took the stormtroopers out in hand - to - hand combat . She then pursued the rebels on her personal starship " Shadow Caster " . In space , Ketsu quickly caught up with the rebels ' shuttle and managed to disable its hyperdrive . Ketsu then shot open the shuttle ' s side door , causing a hull breach which sucked Chopper out into the vacuum of space . Satisfied that she made her point , Onyo brought the " Shadow Caster " face - to - face with the rebels ' shuttle and repeated her ultimatum to Sabine . Unknown to Ketsu , Chopper had survived the breach and had managed to use his rocket booster s to sneak up on the " Shadow Caster " . Having noticed that Chopper was sabotaging the " Shadow Caster " main turbolaser turret , Sabine deliberately prolonged their conversation to give Chopper enough time to complete his work . When Onyo expressed pride at working for Black Sun , Sabine derided the crime syndicate as a bunch of slaver s and assassin s . After Sabine rejected her ultimatum again , Onyo reluctantly opened fire on Wren ' s shuttle only to discover that her turret had been sabotaged . This gave enough time for Sabine to escape in her shuttle . However , Onyo managed to trap Chopper with the " Shadow Caster " tractor beam s and took him prisoner . Communicating with Sabine over the intercom , Sabine offered to trade Chopper for EG - 86 . Unwilling to abandon her rebel comrade to Ketsu , Sabine reluctantly returned and docked her shuttle with the " Shadow Caster " . Meeting face to face , Ketsu discovered that Sabine was determined not to give up the courier droid . She offered to split the bounty but Wren was not interested in profits and reiterated her devotion to the Rebel cause . Onyo was skeptical that the rebellion would succeed and responded that she was solely concerned with her own survival . After a tense discussion , the two former friends reconciled and Sabine forgave Ketsu for abandoning her . Their reunion was however interrupted by the arrival of an Imperial " Arquitens " - class command cruiser , which had responded to the theft of the shuttle . Sabine quickly improvised an escape plan which involved exploding the shuttle to create a distraction that would allow the rebels , Ketsu , and EG - 86 to escape on the " Shadow Caster " . Ketsu cooperated with Sabine ' s plan and personally evacuated her old friend after Sabine was knocked out by an Imperial laser blast . Sabine ' s plan succeeded and they managed to escape in Ketsu ' s starship . Following their escape , Ketsu and the rebels traveled to Havoc Outpost where they delivered EG - 86 to a group of Alderaanian rebels that included the astromech droid R2 - D2 . Ketsu then brought her rebel allies back to Garel . Due to her efforts in helping the rebels to deliver EG - 86 , Ketsu was thanked by Phoenix Leader Hera Syndulla , the leader of Sabine ' s rebel cell . Before departing , Sabine told Onyo that she would always be welcome in the rebellion . Ketsu then departed on the " Shadow Caster " . Hunting the Black Nail . Shortly thereafter , Onyo was hired to capture Jarret , a human male who had once worked as an enforcer for the Black Sun under the alias of " the Black Nail . " After tracking him to the desert planet Ammon IV , she travelled there with a box full of Imperial blasters rigged to explode on request . When she arrived at Jarret ' s homestead , however , she found that the man and his family were already in a showdown with a Kruno ' s band of thugs . Faking exhaustion , Onyo allowed the thugs to seize the blasters and remotely activated the blasters , removing the gang from the face of Ammon IV . At first , Jarret moved to thank his savior , but the bounty hunter threw him a hard punch in the face , revealing that she had come to collect the bounty on his head . When Jarret ' s wife Loris started to plead for her husband ' s life , Onyo recounted how the Black Nail had been a sadistic killer . As it turned out , Loris knew all about her husband ' s dark past , but was conviced he had truly changed . When their son Bron tried to intervene , pointing a skinny blaster rifle at Onyo , Jarret finally decided to surrender . Onyo found herself unexpectedly moved by Jarret ' s acceptance of his fate , as well as his desire to keep his son out of the cycle of violence . Realizing that Sabine Wren had recently given her a second chance in life , the bounty hunter decided to give Jarret the beneift of the doubt . Instead of killing him , she left with his ripped and bloodied shirt , so her clients would believe he was dead . Assisting the rebellion . Ketsu attended a briefing on the captured Imperial light carrier that had become the Phoenix Cell ' s headquarters . By cross - referencing several Galactic Republic and Lasat maps , the rebels found that the planet Berzite ' s moon in the Yost system was a prospective candidate for a rebel base . Ketsu advocated setting up a base on Berzite ' s moon on the grounds that the Empire did not have a presence there . However , the rebels were unable to make the trip since the Yost system was a few parsec s away and their cruiser - carrier was running low on fuel . Sabine , who had been studying Imperial fleet movements , mentioned that an Imperial fuel shipment was arriving at Horizon Base . Commander Jun Sato approved of the plan and sent the Spectres to steal the fuel . When the Phoenix fleet came under attack from Imperial forces under Admiral Kassius Konstantine , Onyo used the " Shadow Caster " to clear a path for the rebel starship , the " Ghost " , to land safely in one of the carrier ' s hangar bays . After officially leaving Black Sun , Ketsu went with Sabine to Garel City . There , they planned to steal several food containers and supplies for the Rebellion . Ketsu and Sabine were then able to knockout several storm troopers with their helmets . They were then confronted by several blaster wielding storm troopers . Ketsu then rescued a young Chadra - Fan boy from a falling food container . She and Sabine then met with the Hera and the " Ghost " . After dropping off the boy , Ketsu then decided to join the Rebellion . Ketsu then rendezvous with Sabine and Hera at Garel City on their bikes . Ketsu ' s bike exploded , but she survived it .

After helping Wren escape , the two became bounty hunters and hoped to work for the Black Sun crime syndicate . According to Sabine , Ketsu then got " greedy " , left her for dead , and went to join the Black Sun by herself . As a bounty hunter in the service of Black Sun , Ketsu was ruthless , self - centered , and goal - oriented . Despite her mercenary streak , Ketsu still could not bring herself to kill her former friend Sabine during a mission to obtain the GNK - series power droid EG - 86 . When Sabine chose to forgive her , Ketsu responded well to her friend ' s grace and admired Sabine ' s team spirit and devotion to the rebellion . She helped her formerly estranged friend to escape the Empire and deliver EG - 86 to the rebellion .
