If you are a fan of the Star Wars obscure, then Lobot is right up your alley. Seen only once in the original trilogy, Lobot is the computer liaison officer of Lando Calrissian’s mining facility on Bespin.
He is a human, but sports a fancy piece of headgear, the Lobot-Tech Headgear as cited by the official Star Wars databank, that allows him to interface with the facilities computer system. This piece of tech was standard issue from the Imperial military and is designed to make workers more efficient while also wiping out any trace of personality.
While Lobot was technically an Imperial slave, he had his moment of heroism when he planned and executed a trap for the Imperial troops that were on Bespin during the capture of Han Solo in The Empire Strikes Back. This trap allowed Lando, Leia, and Chewbacca to escape the facility, and allowed Luke to work his way further into the station where he had his showdown with Darth Vader.
Lobot is seen again in Star Wars: Uprising, a video game that takes place immediately after the events of Return of the Jedi. In the game, the Bespin mining facility is still under Imperial control, but Lobot, still on the inside, passes messages and information to Lando that help him get through the blockade of the facility and overthrow the remaining Imperial presence on Cloud City.
Lobot is played by John Hollis in Empire Strikes Back.
