Kamelion trvelled with the Doctor between The King's Demons and Planet of Fire. He was a shape-shifting android discovered by the Master on Xeriphas. The Master used Kamelion to impersonate King John, in a plan to prevent the Magna Carta from being signed. He could be controlled by telekinetic power. The Doctor fought a battle of wills with The Master to gain control of Kamelion.

Kamelion was an advanced artificial intelligence, capable of independent thought and possessed of a conscience. He was aware that he was being used for evil. He asked to join the Doctor, Tegan and Turlough, and was welcomed aboard. Even so, he rarely appeared in the stories, being confined to the TARDIS. In The Planet of Fire Kamelion eventually came back under the influence of the Master. He was once more used against his will for evil. The mental anguish and physical pain was too much for him and he begged The Doctor to terminate his life. The Doctor reluctantly agreed to do so using The Master’s Tissue Compression Eliminator weapon.

Gerald Flood was born in Portsmouth, son of a Naval family. He was a wireless operator during the War and worked as a filing clerk after the War ended until he landed a job with the Farnham Repertory Company. It was there that he met his future wife, Anne.

Other television roles followed, including "The Ratcatchers" (1966/67), "A Sharp Intake of Breath," "Third Time Lucky" and "Bleak House."
