Lucy Skinner

Lucy Skinner worked with her father Nicholas at the Tycho Project radio telescope in the small English village of Goblin's Copse.

Two strange lights (which interfered with the observatory's telescope transmissions) appeared one night. Her father and she investigated. They were abducted by Commander Kaagh, the sole surviving member of the Tenth Sontaran Battle Fleet, who attached a neural control mechanism to her neck, though it was left un-activated, for use in a back-up plan.

Lucy was released and met Sarah Jane Smith and her young allies, as Kaagh had suspected might happen and, controlled by the device, began to carry out Kaagh's plan to destroy Earth. Sarah used her sonic lipstick to deactivate Kaagh's mind-control device. (SJA: The Last Sontaran)
