Malpha

Malpha was one of the representatives on the Galactic Council who planned to conquer the Solar System with the aid of the Daleks. He was last to arrive at their first conference but took a leading role in that meeting. He had a lesser presence in subsequent meetings. He was one of the few to survive the Daleks' treachery. The First Doctor helped him to escape to his own people and warn them about the Daleks' invasion plans and organise resistance. (TV: Mission to the Unknown, The Daleks' Master Plan)

Appearance
Malpha was tall and well built. His face was covered with a pattern resembling a patchwork, dark lines on pale skin. (TV: Mission to the Unknown, The Daleks' Master Plan)

Abilities
Malpha claimed to possess strength beyond that which a human was capable of. This advantage, he supposed, was because he was a silicon-based lifeform, from a planet with gravity unlike Earth's. He told Jodor Colwyn that he could quite easily "snap [him] like a twig" in their present environment. (AUDIO: The Perfect Prisoners)
