Proto One Proto One , also known as Proto Number 1 , was a rickety Proto Droid who rebuilt himself using assorted replacement parts after he was discarded by his original organic masters . Although he resembled an odd mixture of different droid types and walked with the assistance of a cane , he was proud that he was his own Maker and considered himself one of a kind . In 15 BBY , Proto One was more than a century old , and he worked as the proprietor of a scrapyard on the planet Boonta . When the starship " Sand Sloth " crashed into the scrapyard , Proto One was happy to fix it for its owner , a Human named Kea Moll . After completing the repairs , he discovered that Moll ' s own droids , C - 3PO and R2 - D2 , had unwittingly befriended BL - 17 , a treacherous droid who belonged to the Mandalorian bounty hunter Boba Fett . Proto One helped thwart BL - 17 ' s plan to capture Moll and her friends , and when the nefarious criminals of the Fromm Gang afterward attempted to seize them , the Proto Droid fired a blaster at the gangsters and scared them off . Biography . The Proto Droid who in 15 BBY was known both as Proto One and Proto Number 1 was originally active before the year 115 BBY . After a century of mechanical service , he was discarded by his organic masters . The broken droid rebuilt himself with assorted replacement parts , and his makeshift nature earned him the classification of " junk droid . " Proto One eventually became the proprietor of a scrapyard on the planet Boonta . At some point before 15 BBY , he met and took a disliking to the BL - series droid BL - 17 . One day in 15 BBY , the starship " Sand Sloth " crash - landed in the scrapyard . Proto One approached two of its occupants — the protocol droid C - 3PO and the astromech droid R2 - D2 — who had been ejected from their vehicle during the crash . He introduced himself and earned the affection of R2 - D2 , but C - 3PO was reluctant to trust him , even after he directed the protocol droid ' s three Human masters to a nearby medical unit to tend to the injured arm of Jord Dusat , one of their own . Before the five newcomers departed in their landspeeder , the " White Witch " , Proto One was recruited to fix the " Sand Sloth " by its owner , Kea Moll . Proto One completed the repairs before the day ' s end and left the scrapyard to seek out Moll and the others . He found C - 3PO and the " White Witch " at a processing plant with BL - 17 , who had deceptively befriended the protocol droid in order for his master , the Mandalorian bounty hunter Boba Fett , to capture Moll and her friends . Proto One charged at his old enemy but was easily tossed aside . However , C - 3PO realized BL - 17 ' s treachery and defeated him when R2 - D2 arrived and helped the protocol droid push their foe under a rain of falling machinery . Moll and her friend Thall Joben showed up soon after , but Fett emerged from the shadows and began to fire laser blasts at them . During the commotion , a downed Proto One witnessed Tig Fromm and Vlix Oncard — Annoo - dat Blue gangsters of the Fromm Gang criminal organization who had hired Fett and who sought to thwart Moll and her friends — plant a thermal detonator aboard the " White Witch " and reveal that it would activate after the vehicle completed ten laps of the upcoming Boonta Speeder Race . By the time Proto One got up and warned Moll and C - 3PO , Joben and R2 - D2 had already boarded the speeder and fled from a pursuing Fett . Although Joben entered the race before his friends could contact him , he won the event after Fett ' s own " Silver Speeder " shook the detonator loose and took the brunt of the ensuing explosion . Proto One made his way to the racetrack and saw Oncard , Tig Fromm , and Tig ' s father Sise Fromm confront Joben , Moll , Dusat , C - 3PO , and R2 - D2 . The gangsters fled when Proto One fired a blaster at them , but a furious Fett captured them and decided to deliver them to their rival crime lord Jabba the Hutt . Proto One declined an invitation from an apologetic C - 3PO to leave Boonta aboard the " Sand Sloth " , and he waved goodbye to his new friends as they returned to their ship and departed the planet . Characteristics . After refitting himself with diverse replacement parts , Proto One resembled a strange mixture of different droid types . He was in fact a masculine - programmed Proto Droid , although cobbled - together mechanical beings were more broadly known as junk droids . Proto One stood approximately 1 . 71 meters tall and was humanoid in shape . His head , torso , left hand , and right upper leg were olive - green in color , while his midsection , photoreceptors , right forearm and left leg were red . His left arm , right upper arm , and right foreleg were gray , as were portions of his face , chest , and his right foot , which was also partly black . Proto One ' s body sported several scattered red patches , and a red rectangular prism was fitted to his back . The rickety droid walked on two legs with the use of a cane ; his left foot was roughly the shape of a Human ' s , but his right foot was conical with three tripodal legs of its own . Proto One had three fingers and an opposable thumb on each hand . His face sported red piping above his photoreceptors that simulated eyebrows , and additional red piping around the back of his head gave him the look of a balding Human . The bottom of his face contained his vocabulator and was vertically elongated to resemble a chin and mouth . Proto One was friendly and helpful to strangers who wandered into his scrapyard , but he was quick to beligerently point out that he was his own Maker . Despite the junk droid ' s mostly polite demeanor , BL - 17 earned his ire at some point in his operational history . R2 - D2 took an instant shine to Proto One , but C - 3PO was hesitant to trust the old droid until he discovered BL - 17 ' s deception . A skilled mechanic , Proto One was confident in his abilities despite his advanced age , and he was happy to fix the " Sand Sloth " for Kea Moll and her friends . He considered Boonta to be his home and declined an invitation from C - 3PO to leave the planet . Proto One spoke Basic and also understood Binary . Behind the scenes . Proto One first appeared in " Star Wars " canon in " A Race to the Finish , " a 1985 episode of the " " cartoon series . The episode was written by Peter Sauder and Steven Wright , directed by Raymond Jafelice , and first broadcast on television on September 28 , 1985 . Proto One was voiced by Graeme Campbell .

Proto One has also been mentioned in various " Star Wars " sourcebooks . A was produced by Kenner toys in 1985 , and although it did not include a Proto One figure , " Star Wars " artist Jeffery Carlisle named the character in an interview on StarWars . com as a toy he wished had been produced .
