2 - 1B / Legends 2 - 1B ( or Too - Onebee ) was a 2 - 1B surgical droid that joined the Alliance to Restore the Republic as a medic . The droid was highly sophisticated , belonging to the older , yet remarkably astute 2 - 1B series . Because of his intellect , Too - Onebee was fiercely independent and morality - driven . His gentle touch can be attributed to his precise hydraulic systems , which utilized several liquids at different temperatures . Biography . One of Too - Onebee ' s earliest assignments found him serving the Galactic Empire on the planet Firro , a world recently subjugated by the Imperials . There , he was tasked with providing medical care to the civilians of Firro who were injured by Imperial atrocities . It was Too - Onebee ' s thankless job to mop up after what the Empire had left of the people there . After months of treating an unending parade of wounded , the number of people coming to see Too - Onebee began to decrease as the Empire settled in for a long occupation of the planet . It was then that the talented medical droid came under notice of Lord Cuvir , the newly proclaimed Governor of Firro while on an inspection of a crowded relief station . Cuvir , seeing the droid ' s determined efficiency and skill , took Too - Onebee as his own personal physician , ignoring the needs of the civilian wounded . Too - Onebee was distressed at having to leave the large numbers of wounded and disapproved of his new master ' s overbearing ways , but was forced to serve him faithfully in accordance with his overriding programming directive — to heal living beings no matter whom they might be . Nevertheless , he longed to serve those he thought were on the " right " side . Too - Onebee ' s opportunity to do the " right " thing would soon come . He accompanied Lord Cuvir on a visit to the planet Wor Tandell . While inspecting the medical facilities at the governor ' s mansion , he witnessed the assassination of Cuvir at the hands of one of the governor ' s aides . Staying true to his programming , Too - Onebee attempted to treat the mortally wounded Cuvir , despite believing him to be the most evil being he had ever encountered . The droid soon discovered the aide to be an undercover Rebel agent who identified himself only as Tiree . The man was , in actuality , agent Tay Vanis . Vanis had been secretly collecting information on Imperial fleet movements in the Tandell system when he was discovered by Cuvir . Vanis was forced to kill the Governor to protect his mission . Too - Onebee believed the man , having long dreamed about the rumored Rebellion . He accompanied Vanis in his escape and joined the Rebel Alliance . The droid served with Vanis on a few missions before being assigned to his most important role for the Rebellion . Along with FX - 7 , Too - Onebee arrived at Echo Base on Hoth and was quickly assigned as the head of the base infirmary . Too - Onebee was named chief of surgery . The two medical droids treated a variety of injuries and patients , including Luke Skywalker ' s wampa scarring in 3 ABY . After the Battle of Hoth , Too - Onebee was evacuated aboard the GR - 75 medium transport " Bright Hope " . After the transport was destroyed attempting to run the Imperial blockade , Too - Onebee reached the Rebel underground on the planet Darlyn Boda , where he served for a short time , before finally reaching the secret Rebel rendezvous point . There , he was immediately assigned to the EF76 Nebulon - B escort frigate " Redemption " to treat surviving wounded from Hoth . Luke Skywalker was so impressed with the droid ' s skill and expertise that he specifically requested him to treat the wounds he sustained in his battle with Darth Vader on Bespin while recovering aboard the " Redemption " . Too - Onebee was reassigned to the Mon Calamari Star Cruiser " Home One " sometime thereafter , where he served during the Battle of Endor . He continued to serve the New Republic after 4 ABY . Behind the scenes . For a brief period , 2 - 1B had his own regular column in various official " Star Wars " magazines . In this short - lived feature he would respond to reader mail . He was portrayed as having a large ego , constantly mocking FX - 7 and claiming that he was the hero of the Rebellion for such acts as saving Luke Skywalker . This was referenced by Daniel Wallace with the quote that accompanied 2 - 1B ' s entry in " The New Essential Guide to Droids " . The article was a " response " concerning how Mara Jade , an Expanded Universe character , was given a model and the cover of the " Star Wars Insider " , while 2 - 1B , a character who was actually from the films , was not given a cover shot . 2 - 1B was voiced by Charles Martinet in the game " " . Two 2 - 1B units are seen working on Darth Vader in the Imperial rehabilitation center on Coruscant at the end of ; but neither of them is intended to be the same unit droid shown in , who heals Luke ' s injuries from the Wampa and repairs his hand after his duel in Cloud City .
