Teesee was manufactured in the Cybot Galactica droid foundries on Etti IV around 7BBY. He was sold directly to a interplanetary trading company, and operated as receptionist for many years. When the company replaced him with a later model, his mind was wiped and he was sold to a second-hand droid-sales company. He was picked up cheaply by Rahmus Baktran, and he entered into Night Jedi service and was taken to Endor.
