Lobot is the computer liaison officer of Cloud City. The cyborg brace that envelops his skull is packed with sophisticated computer circuitry that keeps him in constant touch with Cloud City's nerve center. Lobot has served Cloud City through several administrators, and his loyalty is to the health and welfare of the floating metropolis' citizenry.
Lobot was once a slave who had gravitated to Bespin as a vagabond. Convicted of robbery in Cloud City, Lobot was sentenced to serve the city. The then-administrator, Baroness Ellisa Shallence, decreed that rather than serving out a lengthy prison sentence, Lobot should instead indenture himself to the city as a cyborg computer liaison officer.
After the Imperial takeover of Cloud City, Lobot continued to serve in that capacity. His cyborg implant was damaged during an ill-fated Ugnaught insurrection of the floating metropolis, but he was ultimately brought back to working order.
