2-1B

From Ewokpedia

2-1B was an Imperial loverbot assigned to Darth Vader's Executor class command carrier, but grew tired of having his lovers unceremoniously throttled to death by the Sith Lord. He abandoned the Empire and eventually joined the Rebels, only to be involved in an illicit tryst with Luuke Skywalker during the latter's recuperation on Hoth after a vicious tauntaun attack. 2-1B was eventually dismissed from service after attempting to facilitate a three-way with Luuke and Leia wherein they pretended to be siblings.
