Theory:Timeline - Fourth Doctor

Index → Timey-wimey detector → Timeline - Fourth Doctor
Spoilers are strongly policed here.
If this thread's title doesn't specify it's spoilery, don't bring any up.

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.

Limiting factors

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

The Doctor regenerates from his previous incarnation inside his UNIT laboratory with the aid of Cho-Je.
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.
Sneaking away from UNIT during the events of Robot, presumably during the overnight time-skip in Part Two, the Doctor visits the Mordee colony, and attempts to repair their supercomputer.

Missions surrounding the Nerva Beacon

  5. ↑ "I watched you," Leela said, "and I copied what I saw you do." She found a piece of rotten wood and weighed it in her hand. It was too light and she discarded it. "The TARDIS is a machine – there is nothing magic about it. And you can stop calling it the travelling hut. It is not funny to mock people's lack of knowledge, Doctor. Especially when you are stuck up a tree."
  6. ↑ The Doctor's scarf was all sorts of different colours and Leela was wearing jeans Mum said later that "she must have been greased into" and a big grey jumper that smelt funny. She was always VERY serious but not in the way like teachers are. She had very bright blue eyes and nice dark hair.
