Biography
Mary, Andy and Jeff lived in New Paris, Venus, but were on holiday in the planet's Churchill Mountains when the Daleks attacked. When Jeff and Mary were captured, Andy set out to free them. He found Jeff at a lead mine, and together they located Mary at Winston Dam. Andy and Mary were later captured by Daleks on Gurnian and forced to approach a group of Horrorkons, which they later used to defeat the Daleks. On Mercury, he trained an army of ants to carry rust and spread it among the Daleks. Later, he and the other Stones discovered and defeated a Dalek plot to destroy Earth. (DAN: The Dalek Book)
