(PROSE: A Honeycomb of Souls) A peasant who had been sent to 1970s London by a time eddy also believed the Third Doctor was a wizard when he saw him. (TV: Invasion of the Dinosaurs) However, after dropping the "Qui Quae Quod" disguise, the Doctor insisted to Thorpe that he was not "a magician or a wizard or anything of the sort", maintaining that his and the Master's abilities as Time Lords and men of science were entirely different from folkloric "magic".

Many individuals used the name at one point or another, including the Master (PROSE: The Creation of Camelot) and several incarnations of the Doctor, (TV: Battlefield, PROSE: One Fateful Knight, Legends of Camelot) as "the Merlin" was actually the official title for the astrologer of Camelot's court, rather than a personal name. (PROSE: The Creation of Camelot) One Merlin had a sister called Ganeida, who was a wizard like himself; they were both of half-demon heritage. (PROSE: A Honeycomb of Souls)
