E-3PO
this chrome-plated protocol droid was part of the Imperial garrison which was stationed on Cloud City. E-3PO's assigned role was that of human-to-alien translator, a role he fulfilled when he relayed to Ugloste the necessary modifications to allow carbon-freezing to work on humans. E-3PO nearly ran into C-3PO, shortly after Han Solo and the Millennium Falcon arrived at Bespin in the wake of the Battle of Hoth.
