Theory:Timeline - Fourth Doctor

This page lists appearances of the Fourth Doctor in the order in which he experienced them. This timeline is based on observations of the Doctor Who universe and the events in each of these stories. From these observations we have attempted to build a concise timeline. It is assumed, much like their TV story counterparts, that for each novel or audio series their published/numbered order is the order they occur in. There are also many gaps between stories.

The layout of this timeline is based in part on the observations on Doctor Who Reference Guide and Doctor Who - The Complete Adventures, Lance Parkin's AHistory and other sources that allow us to make observations, such as DocOhoReviews, Doc Oho's Book Reviews, The History of the Doctor, The Discontinuity Guide, Clive Banks Databank, Whopix, the Big Finish forums and The Divergent Universe forums. None of these sources should be used solely as a source or considered a "true" timeline for stories.

Companions
Any story with Sarah Jane Smith must take place before TV: The Hand of Fear.

Any story with Leela must take place after TV: The Face of Evil and before TV: The Invasion of Time.

Any story with K9 Mark I must take place after TV: The Invisible Enemy and before TV: The Invasion of Time. Any story with K9 Mark II must take place after TV: The Invasion of Time and before TV: Warriors' Gate.

Any story with Romana I must take place after TV: The Ribos Operation and before TV: Destiny of the Daleks. Any story with Romana II must take place after TV: Destiny of the Daleks and before TV: Warriors' Gate.

Any story with Adric must be set after TV: Full Circle.

Costume
The Fourth Doctor has an advantage when dating his stories due to his costume. The Doctor started out with a short red blazer, a rainbow scarf, and tweed trousers. He soon switched to longer frock coats, in colors of grey, dark red, and dark brown. Eventually, his costume turned into the "red" version. This makes dating very simple when looking at how the Doctor is dressed (with the exception of certain oddities, like PROSE: The Sinister Sponge).

Timeline

A new body

 * TV: Planet of the Spiders
 * The Doctor regenerates from his previous incarnation inside his UNIT laboratory with the aid of Cho-Je.


 * TV: Robot
 * Set immediately after Planet of the Spiders, with the Doctor recovering from his regeneration. Though he intends a fresh start by leaving UNIT behind, the Doctor agrees to help them confront the Scientific Reform Society and their mishandling of K1 in a bid to hold the world hostage with nuclear bombs. Once the crisis is resolved with K1's destruction, the Doctor asks Sarah to continue traveling with him, with UNIT doctor Harry Sullivan following them into the TARDIS.


 * PROSE: Doctor Who and the Face of Evil

Missions surrounding the Nerva Beacon

 * TV: The Ark in Space
 * Harry is taking his first trip in the TARDIS, setting this immediately after Robot. The TARDIS crew arrive at the Nerva Beacon due to Harry fiddling with TARDIS, and assist its crew in fending off the Wirrn.

 * Despite the interference of the Sontaran Field Major Styre, the TARDIS crew manage to fix the faulty equipment on Earth and beam back to the Nerva Beacon.


 * TV: Genesis of the Daleks
 * Set immediately after The Sontaran Experiment, with the Time Lords intercepting to transmat beam and giving the Doctor a mission to disrupt the creation of the Daleks to prevent them becoming a greater threat, and also giving him a Time Ring to allow him, Sarah and Harry to escape Skaro. The Doctor meets the Daleks' creator, Davros, for the first time, and, while he is unable to prevent their creation, he hypothesises that his interference has delayed the Daleks' development by a thousand years. After he watches the Daleks exterminate Davros, the Doctor uses the Time Ring to take him, Sarah and Harry away from Skaro.

However, this ending was scrapped.


 * TV: Revenge of the Cybermen
 * The Time Ring brings the Doctor, Sarah and Harry back to the Nerva Beacon, though thousands of years too early, and then returns to the Time Lords.
