Ploughman

From Tardis Wiki, the free Doctor Who reference

Mr Ploughman was an old man who lived in Bannerman Road. He was possessed by Janksia, an alien from the planet Persopolis.

Ploughman knew of Sarah Jane Smith. He allowed her son, Luke Smith, to do his shopping at the supermarket for him and he became embroiled in their adventures when the alien Janksia, who had been in suspended animation for a thousand years, took possession of his body. Luke and Clyde Langer released Ploughman and the sight of Janxia made him faint. (AUDIO: The Time Capsule)
