Blue was a customized protocol droid who served the Koorivar black market merchant Sheb Valaad during the Clone Wars . Sheb had purchased Blue equipped with two specialized programs : " Adul - 8 " and " B - Little . " While Adul 8 soothed Sheb , B - Little entertained the Koorivar merchant . Blue ' s master Sheb specialized in selling the stolen jewels , painting s , statues , and other objects of makers who had met " unpleasant fates . " Sometimes , Sheb even ordered his henchmen to murder artisans so that he could seize their property . Sheb ' s activities eventually attracted the attention of the undercover Jedi Master Quinlan Vos . Disguised as the Kiffar " Master Tal , Vos regularly patronized Sheb ' s shop and bought some items to gain Sheb ' s trust . During these visits , Tal fraternized with the droid . On one such visit , Blue entertained Tal and informed the Kiffar buyer that his master had agreed to grant him an audience . When Tal told Blue not to call him master , the droid apologized that his current program setting did not allow him to override that designation . After the Gamorrean guard Thurg ascertained that Tal was unarmed , Blue allowed Tal to meet with his master . Knowing that the droid could speak multiple language s , Tal then asked Blue how many synonyms his name had in all the languages stored in his databank s . Before the droid could go on verbal overload , Sheb told the droid to ignore Tal ' s instruction and warned the visitor that he expected compensation should his droid incur any damages . One of Sheb ' s Twi ' lek assistants then brought the small statuette of an aquatic creature for the benefit of Tal . Before Tal could examine the object , Tal ' s Jedi Mahran colleague Akar - Deshu ( " Desh " ) entered Sheb ' s shop . Desh had been sent by the Jedi High Council to bring Vos back to Coruscant for a new assignment . Tal then took the opportunity to attack Sheb by levitating him with the Force . Alarmed , Blue ran out of the room and brought several body guards to rescue his master . While Blue chattered in the corner , the two Jedi quickly overpowered Sheb ' s bodyguards with their lightsaber s and Force power s . When Blue attempted to reach for one of the fallen bodyguards ' comlink , Tal sliced off one of his hands with his lightsaber . When Blue gave a high pitched shriek , Tal told him that it could be fixed and chided him not to be a " baby . " While Vos was annoyed with Desh for prematurely blowing his cover , he was satisfied that he had learned about Sheb ' s contacts during his time working undercover . Vos had also used his psychometric powers to trace the ill - gotten objects back to their rightful owners . Before leaving , Vos asked Blue to repeat every known synonym for blue , which numbered in the billions , in order to annoy Sheb . Personality and traits .
