In The Day of the Doctor, we learn about a new Doctor, aka the "War Doctor", who fit somewhere before the Ninth Doctor (Christopher Eccleston).

At the end of the episode, we also saw the War Doctor regenerating, but we don't see into which incarnation of the Doctor he regenerates.

Which raises the question, are we sure about the regeneration order of the Doctor? I saw myself the Ninth Doctor regenerating into the Tenth and the Tenth into the Eleventh, but what about the others? Could the incarnation order be rearranged in some way so the Eleventh Doctor become the Fifth or something like that?

    And maybe Hartnell wasn't really the 1st? – Andrew Lewis Nov 25 '13 at 15:46

    @AndrewLewis in The Name of the Doctor, Clara Oswald suggest to the First Doctor he should steal a different TARDIS because although its navigation system is "knackered" he'll have "loads more fun". Only the first Doctor could steal that TARDIS. – DavRob60 Nov 26 '13 at 1:09

    @DavRob60: why could only the first Doctor steal that Tardis? Why couldn’t there have been regenerations before that one? – Paul D. Waite Dec 17 '13 at 11:26

Could the incarnation order be rearranged in some way so the Eleventh Doctor become the Fifth or something like that?

Nope.

Two things in The Day of the Doctor strongly suggest that John Hurt regenerates into Christopher Eccleston:

  1. As Hurt regenerates, he says that he hopes his ears will be less prominent this time. In Eccleston’s first appearance, he comments on his own prominent ears, making Hurt’s line funny.

  2. When the camera cuts away from Hurt mid-transformation, it certainly looks as if he’s turning into Eccleston. Although it’s still possible that Hurt regenerates into someone else, I think that given Eccleston was unwilling or unavailable to return for this special, this is as close as the programme-makers could get to confirming that Hurt regenerates into Eccleston.

The War Doctor regenerating into the 9th Doctor

In Doctor Who (1996) we saw McCoy regenerate into McGann, and in the minisode The Night of the Doctor we (effectively) saw McGann regenerate into Hurt, so seven (McCoy) through thirteen (Capaldi) are locked down.

As for the original series Doctors, I’m not familiar with that run of the show, but @Micah’s answer (reward it with many upvotes!) states that the only missing regeneration is that from Troughton to Pertwee: Troughton's Doctor dies at the end of The War Games, and the beginning of Spearhead from Space shows Pertwee emerging from the TARDIS. So, in theory more Doctors could be fitted in between Troughton and Perwee, but even Steven Moffat might have a hard time looping a later Doctor like Matt Smith back through the eye of that particular needle.

(Also, technically, Colin Baker wasn't present for the regeneration to McCoy; instead, McCoy wore a blonde wig and was only shot from behind.)

    As I recall there were a few transformations that were left unclear until the next doctor was available but in those cases, the companion was at least consistent so it would be hard to sneak in an extra regeneration. – mikebabcock Nov 24 '13 at 19:24

    @mikebabcock: Mostly true (certainly in the case of 6th, Baker, to 7th, McCoy) but not in the case of 2nd to 3rd (Time Lords wiped the memory of Jamie and Zoe (IIRC) and sent them back to their own time before enforcing the re-generation and exiling The Doctor on Earth). All the other original series re-generations were seen fully. See the other answer :-) – Richard Nov 24 '13 at 22:32

    In the closing credits the faces of previous Doctors were shown, with Hurt between McGann and Ecclestone and everyone else in the conventional order. – Henry Nov 24 '13 at 22:57
  • @Henry: sure, but near the end of Matt Smith’s first episode, the faces of all the past Doctors minus Hurt were shown. – Paul D. Waite Nov 27 '13 at 16:37

There is one classic-era regeneration that's not shown on screen: the one in which the Second Doctor regenerates into the Third. As tardis.wiki.com says:

...the regeneration of the Second Doctor (played by Patrick Troughton) into the Third Doctor (played by Jon Pertwee) was never explicitly shown on television - although the Second Doctor's face is shown beginning to change and contort, and then disappear, as he spins away into the void. Instead, viewers were left only with the impression that the Doctor had been sentenced to two fates: enforced regeneration and exile on Earth.

This occurs at the end of season 6; at the beginning of season 7, the Doctor has in fact regenerated and been exiled. However, several discrepancies (mostly in later multi-Doctor episodes where the Second Doctor appeared to be older and to have more knowledge than he ever had in his ordinary tenure) led to speculation that this sentence had been delayed for a time, and he had continued adventuring throughout a "Season 6B". This speculation eventually made its way into several spinoff novels, so if you take those as part of your Doctor Who canon you can consider it verified.

All the other classic-era regenerations happened on screen. The only other anomaly is that when the Sixth Doctor regenerated into the Seventh, Colin Baker had already left the show, and so Sylvester McCoy played both. But he clearly is playing the Sixth Doctor and not some unspecified intermediate regeneration.

To the best of my knowledge, nobody ever seems to have considered inserting extra regenerations into season 6B, but if you wanted to add them anywhere that would be the place to do it. Moreover, since all the other regenerations are locked down, you couldn't change the order of the currently-existing Doctors, just insert new ones.

Two additional caveats:

1) "The Time of the Doctor" states that the Eleventh Doctor is on his final regeneration from the first cycle. All the other regenerations from that cycle are accounted for. So if there's an extra season 6B Doctor, or any other unknown doctor in the pre-Trenzalore era, the Doctor must also have gotten an extra regeneration or two from somewhere, or at least be mistaken about Tennant's handy regeneration at the beginning of "Journey's End".

2) "The Day of the Doctor" strongly implies that the Doctor will eventually regenerate back into Tom Baker. If this is a possibility, it's difficult to completely rule out the idea that the Doctor regenerates into some form we've never seen before, but then regenerates back again into their previous form. However, because of point 1), this would probably have to be post-Trenzalore (Capaldi -> unknown -> Capaldi or Whittaker -> unknown -> Whittaker).

    When the Third Doctor steps out of the Tardis at the beginning of "Spearhead From Space", he is apparently wearing the Second Doctor's clothes, suggesting that Jon Pertwee's incarnation directly follows Patrick Troughton's. There is a fan film called "Devious", a short clip of which is in the extra features of the DVD of "The War Games". In this, some rogue Time Lords teleport the Second Doctor into their lab just as he begins to regenerate and stop the regeneration half way through, so the Doctor has a single adventure (still wearing Troughton's clothes) as an "Interim Doctor"... – Wallnut Nov 29 '16 at 13:18
  • ...played by Tony Garner. It's worth seeing for Jon Pertwee's performance at the end, the final time he played the Doctor on screen before he died. – Wallnut Nov 29 '16 at 13:19
  • Out of universe, the programme makers probably didn't think it was that important to show the change from 2 to 3. They had to show the change from 1 to 2 to establish that this really was the Doctor and not a fake. Once it was established that the Doctor could change his appearance, actually showing it may not have seemed that important back in 1969. – Wallnut Nov 29 '16 at 13:22

So, in possible order then:

  • 1st doctor in his 1st Body is William Hartnell

  • 1st Regeneration into 2nd doctor in his 2nd Body is Patrick Thoughton

  • 2nd Regeneration into the 3rd doctor in his 3rd Body is Jon Pertwee

  • 3rd Regeneration into the 4th doctor in his 4th body is Tom Baker

  • 4th Regeneration into the 5th doctor in his 5th body is Peter Davison

  • 5th Regeneration into the 6th doctor in his 6th body is Colin Baker

  • 6th Regeneration into 7th doctor in his 7th body is Sylvestor Mccoy

  • 7th Regeneration into 8th doctor is his 8th body is Paul McGann

  • 8th Regeneration into the "War Doctor" he doesn't give himself the "doctor" name as he wasn't in his mind a good man but he is in his 9th body was John Hurt (note: from this point on, the regeneration is lower by one, because the title "doctor" wasn't used in this case)

  • 9th Regeneration into the 9th doctor in his 10th body is Christopher Eccleston

  • 10th Regeneration into the 10th doctor is in his 11th Body is David Tenant

  • 11th Regeneration is into himself and is still the 10th doctor is still his 11th Body

  • 12th Regeneration is into the 11th doctor in his 12th Body is Matt Smith

  • 13th Regeneration (given an unknown if regeneration's by the old time lords) into the 12th doctor in his 13th Body which is Peter Capaldi

    @N_Soong - I think this is as good as it's going to get. – Wad Cheber Sep 24 '15 at 4:02
  • @WadCheber great edit; like I said I tried but then my mind exploded... ah, no wonder I've been feeling Spockish - how on earth did my emotion chip get all the way over there... ;) – Often Right Sep 24 '15 at 4:03
  • Thanks Wad Cheber for making the post look easier to read, i tried but couldn't get it to do what i wanted - hence the big blog! – FlossyFay Sep 25 '15 at 5:44
  • It was hinted in the Fourth Doctor story "The Brain Of Morbius" that the Doctor had other incarnations before the William Hartnell one, which everyone has different ideas on how to explain away... – Wallnut Nov 29 '16 at 13:20

I have seen this question a lot. Yes, John Hurt regenerates into Christopher Eccleson. The other regenerations are the same. John Hurt is called The War Doctor, or Doctor number 8.5 as I've seen before. My theory is that the Doctor regenerated into that form of the Doctor just for the Last Great Time War. No, the Eleventh Doctor doesn't become the fifth. It gets even more confusing because the Tenth Doctor regenerated twice. Once into himself again, and the second time into Eleven.

    The War Doctor isn't 8.5, he's the true 9th incarnation. You can't have .5 of an incarnation, that'd be stupid. BTW, the 11th Doctor is the 13th – L.J Rob Jan 10 '15 at 14:49

Yes, we're pretty sure:

The Doctor's causes of regeneration:

1st: Was apparently growing weak from old age. He collapsed from exhaustion while battling the Cybermen on Mondas.

First Appearance: An Unearthly Child

Regenerated: The Tenth Planet

2nd: The Time Lords punished the Doctor for breaking their laws of non-interference by forcing him to regenerate into his next incarnation.

First Appearance: The Tenth Planet

Regenerated: The War Games/The Night Walkers

3rd: "Died" from the effects of extreme radiation poisoning caused by the Great One's web of Metebelis crystals. Fellow Time Lord, K'anpo Rimpoche saved the Doctor's life by kick starting the regeneration process, which caused him to change into his 4th incarnation.

First Appearance: Spearhead from Space

Regenerated: Planet of the Spiders

4th: The Master indirectly caused the Doctor to fall from the top of the Pharos Project tower, causing him fatal damage. As he lay injured and dying, the Watcher (a being thought to represent something between the Doctor's 4th and 5th incarnations) merged with the Doctor and saved his life by transforming him into his next incarnation.

First Appearance: Robot

Regenerated: Logopolis

5th: After dropping the contents of the antidote for the pathogen, Spectrox Toxaemia, the Doctor saved Peri Brown by giving her the last vial. He then succumbed to the effects of the disease and regenerated.

First Appearance: Logopolis

Regenerated: The Caves of Androzani

6th: Unknown

First Appearance: The Caves of Androzani

Regenerated: Time and the Rani

7th: Somehow regenerated in a San Francisco hospital's morgue hours after surgeon Grace Holloway, accidentally killed him with anaesthetic and a probe while trying to fix his "heart problem".

First Appearance: Time and the Rani

Regenerated: Doctor Who (1996)

8th: Was killed when the spaceship he was on crashed landed on the Gallifreyan colonial planet called Karn. He was brought back from the brink of death by the Sisterhood of Karn, and regenerated into the War Doctor by drinking a specialised Elixir of Life, so he could fight in the Last Great Time War.

First Appearance: Doctor Who (1996)

Regenerated: The Night of the Doctor

Warrior: After centuries of fighting in the Time War and time locking Gallifrey along with his twelve other incarnations, the War Doctor regenerated after apparently "wearing a bit thin".

First Appearance: The Name of the Doctor

Regenerated: The Day of the Doctor

9th: Absorbed the energy of the Time Vortex from Rose in order to save her life. This caused rapid cellular decay, and he regenerated shortly after in order to save his own life.

First Appearance: Rose

Regenerated: The Parting of the Ways

10th (11th regeneration): Regenerated and healed his body after nearly dying from being grazed by a Dalek's laser beam. Avoided the change into what would have potentially been his 12th incarnation in the nick of time, by directing the transformative energy of the process into his spare hand.

10th (12th regeneration): The Doctor locked himself in a radiation booth and absorbed an amount of rads that would've instantly killed an ordinary man. Held back the process in order to bid a final farewell to his former companions. He eventually regenerated (which destroyed the TARDIS console room) into his 13th incarnation.

First Appearance: The Parting of the Ways

Regenerated: The Stolen Earth/Journey's End, and The End of Time: Part 2

11th: After a near millennia of protecting the people of Trenzalore from many of his old enemies, the Doctor was given a second regeneration cycle by the Time Lords, just as he gave up his life. He used the energy to utterly destroy the Daleks and their entire fleet before returning to the TARDIS in the form of a young man. With the process in its final phase, the Doctor accepted he was always going to be the same person deep down, no matter how many times he changed. He then became a new man a thirteenth time (but regenerated a 13th time), becoming the 12th Doctor.

First Appearance: The End of Time: Part 2

Regenerated: The Time of the Doctor

Compelling evidence that John Hurt's doctor regenerated into Eccleston's is that he was the first to have Rose Tyler as a companion. Since Hurt's doctor was in connection with the Bad Wolf Rose it is possible that some force (universe, TARDIS, or Bad Wolf herself) brought Eccleston's doctor and Rose together even though he forgot the events after his regeneration.
