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 Sixth 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 generally assumed, much like their TV story counterparts, that each novel, comic or audio series their published/numbered order is the order they occur in, although the audio stories that use the Peter Howell theme are often set before audio stories the Dominic Glynn theme. 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 Doctor Who, The Discontinuity Guide, Clive Banks Databanks, Whopix, the Big Finish forums, The Whoniverse and The Divergent Universe forum. None of these sources should be used solely as a source or considered a "true" timeline for stories.

Fates

Due to him turning into the Valeyard during Millennial Rites, the Doctor is influenced to kill himself by echoes of his next incarnation, at least according to PROSE: Head Games.[quote 11] The Doctor and Mel are having a fitness session on the exercise bike when the TARDIS is attacked by the Rani, and, with the HADS deactivated, the Doctor suffers a fatal head injury in the attack.
In the second depiction of his regeneration, the TARDIS is attacked by the Rani as the Doctor is dying from chronon energy starvation after his confrontation with the Lamprey.
In the third depiction of his regeneration, the Doctor is exposed to focused beams of a radiation lethal to Time Lords as a consequence of the Rani's attack on the TARDIS, due to a future version of himself sending him a message on how to defeat the Valeyard's master plan with his death.
The Doctor completes his regeneration into his next incarnation after the TARDIS lands on Lakertya. He is 953-years-old. The exercise bike is back in the console room after being hidden away in Instruments of Darkness.

    PERI: "I don't know which is yourself."
    DOCTOR: "Exactly. This re...generation..."
  2. ↑ DOCTOR: "I must say, I'm surprised to see you. The last time we met, your ship blew up. I thought with you on board."
  3. ↑ PERI: "My home? If they could see me now."
  4. ↑ PERI: "I've coped with the past before, you know."
    DOCTOR: "Well, that past was two hundred years in the future. It's not half so civilised or well drained here."
  5. ↑ PERI: "Doctor! I never thought I'd see you again!"
  6. ↑ FROBISHER: "You've been dragging me all over the galaxy in that contraption of yours for months now... and not once have we arrived where we set off for!"
  7. ↑ DOCTOR: "It'd be rotten luck if you made the wrong choice. Then, I'm very much afraid you'd've had it. In a big way. Just have to begin a new adventure."
  8. ↑ FORD: "Well, that coat may be all the thing in Piccadilly, son, but, here in DC, folks will take you for a theatrical."

  11. ↑ "You were unstable. You were travelling the road that leads to the Valeyard." "I was trying to avoid it!" "But you still met Melanie, you still destroyed the Vervoids. You might have delayed our future but you couldn't avert it. You almost killed Mel on Earth in 1999, when you were so close to becoming the Valeyard yourself. That was when I had to act. I had to come out and stop you."" And kill me!" And terminate your regeneration."
