Kamelion was a shape-changing sentient robot, whose physical form could be changed using psychic force. His short time in the TARDIS began when the Master used him to impersonate the English King John in an attempt to undermine the signing of the Magna Carta. Escaping with the Doctor, Kamelion lived aboard the TARDIS until once more, the Master reached out to control his mind.

The Master - accidentally shrunk to doll-size - used Kamelion to do his bidding. Once control was broken, Kamelion begged the Doctor to destroy him, which - with a heavy heart - the Doctor duly did.
