Unidentified cloning technician A male Imperial cloning technician worked in the cloning facility in Timira City on the planet Kamino around 1 BBY . The cloning technician monitored clones like Subject 1157 , a copy of the Human male Galen Marek . Subject 1157 initially displayed great progress , and the technician was pleased to contribute to scientific progresses . The technician gave memory imprints to the clone . Over time though , Subject 1157 ' s behavior became uncontrollable , and the technician feared that the clone would end in aberration . Later , during the Assault on Kamino of that year , Subject 1157 was killed by the Force - wielding individual Subject 1138 . Biography . A male Imperial cloning technician worked in the cloning facility in Timira City on the planet Kamino around 1 year BBY . The cloning technician monitored test subjects , including Subject 1157 , a clone of Darth Vader ' s apprentice , the Human male Galen Marek . The cloning technician recorded observation logs about Subject 1157 during the clone ' s various development phases . The technician recorded that 1157 had become conscious and was physically stable , and explained that the clone was experiencing tremblings . During his 25th entry about 1157 , the technician reported that Darth Vader was coming as a result of the success of the project and mentioned his pleasure at the scientific progress the technician was making . The technician also monitored 1157 while the clone , like his template , developed Force sensitivity . The technician gave the clone genetic memory imprints throughout his development . Subject 1157 was bothered by " hallucinations " and required systematic restraints to control the resulting tremblings . The technician , as a result , instigated new desensitization techniques . By Entry 65 , the technician hypothesized that the clone would end in aberration due to the clone ' s unstable behavior , and experimented with new sedation techniques . He was unsure how to proceed by that point . Later , Kamino was attacked , and the facility was subject to an evacuation order . In his 78th entry , the technician recorded that on Darth Vader ' s orders , they were abandoning the non - viable test subjects , and 1157 would be released out of his tank to see if the imprint held . The technician expressed a wish that his life ' s work was not in vain . Before Subject 1157 was released , though , an individual referred to as Subject 1138 by the technician struck 1157 ' s tank with a Force push , and the clone expired . Personality and traits . The cloning technician was proud of his work and believed he was furthering a cause by the development of test subjects like 1157 . The cloning technician was well - versed in medical terminology and cloning , although at he one time , in response to Subject 1157 ' s aberrations , was not sure how to proceed . Behind the scenes . Throughout summer 2010 , the cloning technician was a character in the website for the LucasArts " " video game before the site changed to an interactive database and removed the content he was in . The technician provided audio entries recording the development of Subject 1157 for viewers to listen to . The content was also accessible through " Star Wars : The Force Unleashed II " cloning tank website , and the last video is still active on that site .
