Tut-Ankh-Amen

 or Tutankhamun was a pharaoh of ancient Egypt who died as a boy. His tomb lay mostly intact until the 20th century, when it was discovered by Howard Carter. He bore a striking resemblance to Ben Jackson, who was responsible for keeping Tut-Ankh-Amen's tomb intact for over three millennia.

Shortly after the king's death, the Second Doctor materialised the TARDIS inside Tut's tomb. Within a few minutes, the TARDIS crew heard the sound of approaching bandits. Ben donned the mask of the dead king, which fit easily over his similar features and confronted the robbers, wailing like a ghost. They fled, creating a rockslide in their haste that sealed the tomb until the 20th century. (PROSE: The King of Golden Death)

In 1926, the discovery of Tutankhamun's tomb led to an increase in archaeological expeditions in Egypt. One archaeolgist said that Tutankhamun was nothing compared to his discovery of a tomb that held Styx. (COMIC: The Gods Walk Among Us)

Behind the scenes

 * The King of Golden Death (1967) refers to him as "Tut-Ankh-Amen", a hyphenated spelling which has fallen somewhat out of favour. The Gods Walk Among Us (1981) uses the "Tutankhamun" spelling.
 * Although it goes unreferenced, Akhenaten was his father and Nefertiti was his step-mother.
