Never far from Baron Administrator Lando Calrissian's side was Lobot, Calrissian's aide and Cloud City's computer liaison officer. Lobot is a human male with a shiny, brain-enhancing device wrapped around the back of his skull that allowed him to contact directly with the city's central computer.
During the Imperial takeover of Cloud City, Lando trusted Lobot to stay one step ahead of the Imperials. With his wrist communicator, Lando tapped out instructions to Lobot to gather the city's security forces and outmaneuver the stormtroopers.
Cloud City is a gleaming metropolis suspended high above the gaseous surface of Bespin, where it processes valuable Tibanna gas for export. It is a small outpost, ordinarily outside the notice of the Empire.
Lobot and the Cloud City security forces held the stormtroopers that marched Lando and his Rebel prisoners at gunpoint, and moved them to the Security Tower. Lobot was eventually captured by a stormtrooper patrol.
