D ' harhan D ' harhan was a male Niordi bounty hunter who hailed from the planet of Niorde in the Unknown Regions . Niorde came under attack by members of the Leech Legion s during the Clone Wars , who were hired by a neighboring planet to attack Niorde as part of a war that had been fought between the two planets for a century . To defend his planet , D ' harhan and several other Niordi underwent cybernetic alteration to their bodies to become living artillery weapons . However , despite the advantage of having D ' harhan and the other weapons on their side , the Niordi lost the war , leaving D ' harhan the only living weapon left . He and Boba Fett had a long past together , and held each other in high regard . Biography . Early life and transformation . A Near - Human Niordi , D ' harhan was a scout native to the uncharted planet of Niorde , located in the Unknown Regions . Niorde was at war with a neighboring planet for centuries . During the Clone Wars , the latest threat from that world materialized as mercenaries from the Leech Legion who were hired to attack Niorde . Due to this threat , D ' harhan and a select number of other Niordi scouts underwent cybernetic alterations to become living weapons , which would be used to defend their homeworld . On the fringes of the Niorde system in a secret laboratory , D ' harhan ' s head was removed to make way for a cannon that was powered by a light - mass core . His brain was flash - frozen and transferred to a square , heavily - armored box on his chest , while most of his other organs were removed , except for the heart and lungs , which were also relocated . The cannon was connected to his spine via neural - feed cables through a hard - splice socket that was located between his shoulder blades . D ' harhan ' s limbs and spine were also enhanced with durasteel to be able to support the weapon that was drilled into his collarbones , while a tail was added to brace against the recoil from the cannon . His communication was limited by the surgery to the usage of a keypad voice box . An internal comm network was also added to all of the living weapons so that they could coordinate their actions with each other . Throughout the whole surgery , the bounty hunter Boba Fett watched , having been taken to the Niorde system by another hunter , Nashtah . That day , D ' harhan , in essence , became a life - support system for a cannon . By the time D ' harhan and the other Niordi scouts who had survived the operation were ready , the Leech Legions had already conquered Niorde . D ' harhan and the other living weapons attacked the flagship of the enemy , an attack that in the end left only D ' harhan alive . Sometime after the incident , D ' harhan became a bounty hunter . D ' harhan worked with Fett at multiple points in his career , including on Bellassa , hunting down the fugitive Jedi Obi - Wan Kenobi and Ferus Olin . He and Boba Fett attacked Olin , Kenobi , and Trever Flume at the Red Twins spaceport . The Bounty Hunter Wars . During the Bounty Hunter Wars , Fett hired D ' harhan in 0 ABY , to join his team along with IG - 88B , Bossk , and Zuckuss . When he arrived at their meeting point , D ' harhan almost attacked Zuckuss when the Gand touched D ' harhan ' s ship . Boba Fett calmed him down , the two bounty hunters commenting on how long it had been since they had seen one another . The group split in two groups to fly to Circumtore to meet with the Shell Hutts , with D ' harhan joining Zuckuss aboard " Slave I " with Fett . While D ' harhan slept in the cargo hold , his cannon subconsciously tracked Zuckuss ' s movements , frightening the Gand into joining Fett in the cockpit . When Zuckuss — who was disturbed by the cyborg ' s transformation — pressed Fett for more information on D ' harhan , and why he had never heard of him , Fett simply told him that D ' harhan minded his own business , and traveled in areas of the galaxy Zuckuss would never go . After arriving in orbit around Circumtore , the Shell Hutts demanded that all the bounty hunters come down to the planet unarmed . D ' harhan balked at this demand , saying that he " was " a weapon , and would not be able to go . When Fett proposed that they take out his light mass core , the power for the weapon . D ' harhan rejected the offer at first , saying his weapon was his spirit , and that if Fett took that by which D ' harhan killed others , it would be like death to him . Fett told him it would only seem like death , and that real death would come later . D ' harhan relented , and allowed Fett to reach deep inside his inner workings , from which Fett pulled the core . D ' harhan collapsed to the floor , then declared that Fett owed him big time . After meeting with Gheeta planetside , the Hutt betrayed the bounty hunters — due to the fact that Fett had previously rescued an architect that had constructed the palace , Emd Grahvess — and released a large mercenary force upon the group . As the mercenaries attacked — wounding Zuckuss and Bossk — D ' harhan stood in the middle of the room , howling in fury that he couldn ' t fire back . Seeing that their greatest weapon was useless and about to get himself killed in his anger , Fett ran out and slipped the power core back into place , which had been hidden at an earlier date under a dais by the architect , and was revealed only when Fett entered a code into a device on his wrist that detonated it . D ' harhan began to blast away at the mercenaries , decimating their numbers . Soon though , his wounds began to accumulate , as his body was merely flesh and blood . First his knees buckled , then he fell to the ground , unable to hold up the great weight of his cannon any longer . Fett ran out to his comrade once more , and tore free the connections from D ' harhan ' s back , allowing Fett to fire the weapon himself . Fett finished off most of the remaining mercenaries , forcing those who survived to surrender . Gheeta , furious his plan had failed , confronted both the mercenaries and Fett . Fett then pushed D ' harhan forward , placing the cannon inside the Shell Hutt ' s armored body . He fired the weapon inside Gheeta ' s shell , completely liquefying the Hutt . Fett then laid the mortally wounded bounty hunter on the ground , holding him as he lay dying . D ' harhan said he should never have trusted Fett , to which Fett agreed . D ' harhan then said that he could stop now , but Fett still must go on . He then died in Fett ' s arms . Fett would later reflect that he considered D ' harhan to be just another part of his past that had been erased . In the Marzoon sector in 5 ABY , Fett revealed to the Assembler Balancesheet the story of how D ' harhan became enhanced , in exchange for information on a bounty . Weapon system . D ' harhan had , when his planet was at war , submitted himself to a radical surgery , whereupon he was essentially transformed into a walking cannon . This weapon was reportedly strong enough to pierce light starship armor or vaporize enemy infantry . His entire head had been removed , and its functions replaced cybernetically . The cannon , which took the place of D ' harhan ' s head , was bolted to his collarbones , as well as attached to an anchoring plate placed into his chest . A primitive gear functioned as the cannon ' s vertical lifting mechanism . Two power cylinders flanked his metal spine , and power cables looped under his arms and around his chest . He also possessed a saurian - like cybernetic tail , which was long and segmented . When firing , the tail functioned like the back leg of a tripod , steadying D ' harhan against the weapon ' s kick . The weapon was cooled by a relatively primitive cooling system , one that dated back to the early days of the Galactic Republic , which generated a great deal of steam when the weapon was powered up ( such as when D ' harhan was angry ) or when it was firing . The cannon was flanked on either side with targeting sensors and indicator lights , all of which was wired directly into his nervous system . The targeting sensors functioned as his eyes , and the cannon " looked " everywhere D ' harhan did . The indicator lights allowed others to know D ' harhans mood ; yellow was a stand - by mode , orange meant danger , and red meant he was ready to fire . D ' harhan ' s brain was moved to an armored box in his midsection , covered by a thick chest plate . As he no longer possessed a mouth , he required the use of a small box that he kept clipped to his belt , which contained both a speaker and a screen which could silently display words . A keyboard allowed D ' harhan to communicate with others , albeit rarely , and slowly . It was mentioned by Boba Fett , during the mission to Circumtore , that when there were many cyborgs of the same type they communicated through an internal com - link network , presumably also attached directly to the nervous system . During his " sleep " — which was more akin to a stand - by function — the cannon still tracked movements around him , as well as allowed him to both sense when others approached , and hear what was being said .
