Movellan guard

A Movellan guard was a member of Commander Sharrel's expedition to Skaro. She destroyed a Dalek who was attempting to take the Fourth Doctor and Tyssan prisoner but then attempted to take the pair prisoner herself. The Doctor removed the power pack from her belt, deactivating her, then ripped aside her tunic to reveal robotic circuitry, proving his theory that the Movellans were robots to Tyssan.
