"The Masters of Luxor", originally titled "The Robots", was a six-part story submitted by Anthony Coburn while he was part of the BBC Script Department and considered for the second serial of Season 1, in which the Doctor faces a self-aware robot which is trying to gain a soul. It was rejected by the production team in mid-September 1963 in favour of Terry Nation's first Dalek serial. Titan Books published the unused scripts in August 1992. Edited by John McElroy, the text of Coburn's script was amended to fit in with accepted conventions – for example, consistent use of the name "Susan", rather than the "Suzanne" and "Sue" used by Coburn. It was later adapted by Nigel Robinson for Big Finish's "The Lost Stories" in August 2012.
