6J. Doctor Who - The King's Demons

The TARDIS materialises on Earth on 4th March 1215 during a joust. The King welcomes the travellers who he calls his demons.

The Kings is not who he seems. He is in fact a chameleonic android found on the planet Xeriphas, and brought to Earth by the King's Champion, alias the Master.

The Master plans to stop the Magna Carta from being signed by discrediting the King, therefore altering the course of history. The Doctor manages to free the android from the control of the Master, and the Doctor accepts it as a travelling companion.

  • This story introduced Kamelion, a planned companion but who only appeared in one further story.
