2-1B was a 2-1B surgical droid that was a member of the Alliance to Restore the Republic. Along with FX-7, 2-1B was stationed at Echo Base on Hoth. The droid treated Luke Skywalker with bacta after he had been attacked by a Wampa during ‘Empire Strikes Back’. 2-1B also treated Skywalker after his hand was amputated in a duel with Darth Vader on Bespin.
2-1B had long experience with humans, giving him a caring bedside manner. It was thanks to this that Skywalker specifically requested 2-1B’s treatment following the loss of his hand. He was also able to perform extremely precise operations that left little to no scar on his patients.
