Biography . Construction and early life . K - OB7 was manufactured in a Kellenech plant on Rendili sometime before , during , or shortly after the Great Sith War . This was the very same plant in which the LB - series bulk - loading droid T1 - LB was manufactured . Not long after the Great Sith War , Kayo entered into the service of Toki Tollivar , a Sith adept . Kayo always found Tollivar to be pleasant and kind , until one night when he found one of Tollivar ' s associates dead . Kayo found his master horrified and helped him by hiding the body . The next year more and more bodies kept appearing anywhere Kayo and his master went . Kayo was baffled as to how such a small being as Tollivar could strangle so many people . Stranded aboard the " Chancellor Fillorean " . Eventually the Corellian authorities came after Tollivar under his latest alias , Kelven Garnatrope . Tollivar then booked passage onto the " Chancellor Fillorean " , a vessel catering to the ultra - rich . However , the killings started to happen again , and soon all of the passengers and crew aboard the " Fillorean " were dead save for K - OB7 and his master . Tollivar had no idea how to fly a ship like the " Fillorean " and so both Kayo and his master were stranded aboard the ship . Eventually the " Hot Prospect " and her crew — Zayne Carrick , Rohlan Dyre , Jarael and Slyssk , found the ship adrift . As the crew were investigating , Kayo attacked Zayne in an effort to protect his master . Kayo was no match for Zayne and Rohlan , and an innocent - looking Tollivar pleaded for them not to hurt Kayo . Tollivar told Zayne his version of what happened aboard the " Fillorean " , and everyone went off the investigate . Kayo found T1 - LB in the " Hot Prospect " ' s hold and began talking to him . He was able to get Elbee to talk again and even help out with the dead bodies aboard the " Fillorean " . Rohlan Dyre soon figured out that the passengers and crew of the " Fillorean " did not die of asphyxiation , but were instead strangled . Rohlan implicated K - OB7 in the deaths of the passengers and crew of the " Fillorean " . After finding Slyssk nearly strangled to death , Zayne also suspected Kayo of being involved in the deaths and cut off Kayo ' s arms with his lightsaber . Elbee attempted to defend Kayo against Zayne and Rohlan , stating that Kayo was only programmed for " helping . " Kayo then revealed his and Tollivar ' s past to Zayne and Rohlan , raising enough of their suspicions to go after Tollivar . Tollivar revealed himself to be behind all the killings and attempted to strangle Jarael . Zayne and Tollivar dueled until Kayo stepped in . Kayo attempted to incapacitate his master by holding him from behind , and held him fast even as the Sith attempted to free himself with Force Lightning . Rohlan took the opportunity to shoot Kayo and Tollivar with his blaster , killing Tollivar and destroying Kayo . Behind the scenes . John Jackson Miller commented that his inspiration for K - OB7 ' s bug - eyed appearance was the Death Star droid whose action figure he stated was " the creepiest looking thing in the whole Kenner line .
