Urbankan android

Urbankan androids  were humanoid androids used by the Monarch to maintain his ship. Seeing the need for organic bodies as futile, Monarch set out to transfer his and certain abducted humans' consciousnesses into android bodies. When the humans revolted against the Monarch, they programmed the semi-sentient androids to perform cultural routines continuously. After the Monarch was shrunken, Bigon, Lin Futu, Kurkutji and Villagra turned down the Fifth Doctor's offer to return them to their correct times and places on Earth, as they considered themselves to no longer have any place there, deciding instead to travel on and look for a new planet on which to settle.
