Doctor Who pastiches

A number of pastiches of the Doctor have appeared, some "real" in the context of the fiction, others fictional fictional characters. A few have appeared in the Doctor Who Universe itself.

Doctor Who Universe

 * Dr. Who, an inhabitant of the Land of Fiction and/or a creation of the Doctor's own mind
 * Professor X, a television character very similar to the Doctor. He starred in a children's television series of the same name.

Television

 * Mr. X, a puppet who traveled through time and space in his "Whatsis Box" teaching children about history. He appeared early in the Canadian version of Howdy Doody, but was removed due to parental complaints that he was "too scary".
 * Paradox, a heroic time travelling scientist from the American animated series Ben 10: Alien Force.
 * In the BBC soap opera Doctors, Seventh Doctor actor Sylvester McCoy played Graham Capelli, who had played a 1980s children's television character called the Lollipop Man. Dressed as a crossing guard, the Lollipop Man traveled through time and battled alien invaders.

Comics

 * Professor Justin Alphonse Gamble was a minor Marvel Universe character based on the Doctor, though not on any particular incarnation. He had stolen a time machine from the Time Variance Authority and fought the Dalek-like Incinerators.

Direct-to-video

 * The BBV Productions characters the Stranger and Miss Brown, played respectively by Colin Baker and Nicola Bryant, started off as a thinly-veiled version of their Doctor Who roles of the Sixth Doctor and his companion Peri Brown. (Miss Brown, however, used an English rather than American accent, to distinguish her from Peri.) Starting with the fourth adventure of the Stranger, BBV decided to explain away the Stranger as a different character, named Solomon, with an entirely different past.
 * An unfinished fan film, Devious, features a character referred to as "Two-and-a-Half Doctor", a partial incarnation of the Doctor between his Second and Third lives. Also featuring Jon Pertwee as the Third Doctor, the film has been in production since the mid-1990s and a 12-minute excerpt was released by BBC Video in 2009 as a bonus with the DVD of The War Games.

Audio

 * BBV also produced the adventures of the Professor (later called the Dominie, for legal reasons) played by Sylvester McCoy and Ace (played by Sophie Aldred) (later called Alice), as even more thinly veiled versions of the Seventh Doctor and his companion Ace. Depending on your point of view, these might count either as true adventures of the Doctor using an alias or fan fiction using the original actors.

Prose

 * Doctor Omega was the main character of the 1906 French science fiction novel Le Docteur Omega by Arnould Galopin. After Doctor Who nonfiction writer Jean-Marc Lofficier, discovered the character and noticed the similarities between him and the First Doctor. Lofficier and his wife Randy republished the book in an English translation, gave it a new cover similar to that of Chris Achilleos' for Doctor Who in an Exciting Adventure with the Daleks with an introduction by veteran Who writer. Terrance Dicks. Lofficier added lines suggesting that the novel told adventures of the Doctor shortly before An Unearthly Child with the Doctor having taken a brief leave of absence from his grand-daughter Susan Foreman.
