Loose, out of the box. Missing his tool. $20
The 2-1B series was humanoid, with many of its internal components visible through a translucent torso sheath. A 2-1B model's arms featured exceptional joint articulation with precision-crafted servogrip pincers at the end of each limb. Sometimes, in certain operations, these pincers could be removed and replaced with multiple arm attachments containing various medical tools and software packages, including hypodermic injectors and cutting saws.
Two 2-1B units were used by Emperor Palpatine to resuscitate Anakin Skywalker, now Darth Vader, after his vicious scarring and dismemberment on the volcanic world of Mustafar at the hands of Obi-Wan Kenobi, replacing much of his body with bionic prosthetics.
Another droid, known only as 2-1B, defected from the Galactic Empire to serve the Alliance to Restore the Republic. This droid was responsible for treating the famed Luke Skywalker following his encounter with a wampa, and again later after his duel with Darth Vader, in which he lost his right hand.
