Incarnations of the Doctor appearing in Big Finish Doctor Who, the Audio Play series based on Doctor Who.

Please keep in mind that, although the series is officially part of the Whoniverse, it encompasses many different timelines/continuities and includes adaptations of existing works from the Doctor Who Expanded Universe. Due to Big Finish's sheer size and complexity, it also plays by the rules of the Doctor Who Expanded Universe: the TV series can at times contradict or overwrite the timelines described here, or adapt them for the televised continuity.


For a still-growing recap list of the audio dramas featuring these characters, feel free to look here.

Several alternate Doctors appear in Big Finish, who each inhabit their own Alternate Continuity. These have, on rare occasion, interacted with the main timeline.

     Alternate Doctor (Geoffrey Bayldon) 

Alternate First Doctor

Voiced by: Geoffrey Bayldon (2003, 2008)

An alternate incarnation of the Doctor who never chose to leave Gallifrey in the first place. Instead, this Doctor (who is still known as the Doctor) is a novelist, spending his time in simulations and interacting with fictional versions of people on Earth. However, after a long time and in one possibility, he eventually does leave in a TARDIS together with his granddaughter Susan (many, many years after he would have done so in other media). His choices and actions taken, however, aren't tempered by being a grumpy young man, stubborn to keep time intact. So instead, we wound up with spacefaring sailing Steampunk vessels cruising through the solar system in the Elizabethan Era. His story is told in "Auld Mortality" and "A Storm of Angels".

  • Cool Old Guy: While nowhere near as grumpy or (potentially) action-oriented as William Hartnell's version of the character, this Doctor takes a childlike glee in exploring the universe and wants to share it with everyone.
  • Everyone Calls Him "Barkeep": In spite of never leaving Gallifrey, much less exiling himself into the time vortex, the Doctor is still known as the Doctor. Even to the Time Lords, which brings up a potentially interesting question... that's basically ignored anyhow. (Susan is also still called Susan, despite never having gone undercover as a London schoolgirl.)
  • Failed a Spot Check: He doesn't really notice the problems he's caused with his meddling in the time stream until it's finally shoved in his face.
  • Unscrupulous Hero: One of the things retained from the Hartnell's First Doctor. While he adores Susan and cannot stand to see people brought to harm, he also doesn't see the problem with altering history or draining power from the ship that rescued him and Susan from death in space to repower his TARDIS. While it's running into serious problems itself.
  • What Have I Done: Upon realizing he's kinda screwed over the natural flow of history permanently and possibly even doomed humanity.

     Alternate Third Doctor (David Warner) 

Alternate Third Doctor

Voiced by: David Warner (2003, 2008, 2016)

An alternate incarnation of the Doctor, who accidentally arrived for his banishment to Earth a few decades too late. This Doctor appeared in two Big Finish Unbound tales: "Sympathy for the Devil" and "Masters of War" — the former dealing with the consequences to the Earth over the Doctor's inability to interfere with the events of time, with the latter showing off how the Daleks evolved without the Doctor's interference. Took on the Brigadier as a companion, astonishingly. Probably the most significant of the "other" Doctors, he returned again to team up with Bernice Summerfield when she went universe-hopping, in a story which ended with him following Benny back to the main universe and becoming trapped there. He's now living a quiet retirement as a university professor, though he still helps out Benny occasionally.

  • Attention Deficit... Ooh, Shiny!: A trait he shares with many of the Doctors from the main universe which is precisely why, despite being extremely intelligent and being well-intentioned, he makes for a terrible President of the Universe.
  • Awesome Anachronistic Apparel: According to the cover art to The Masters of War, this Doctor seems to wear near-Victorian-era apparel, while having a hairstyle right out of the 1880s. Complete with muttonchops.
  • Beware the Nice Ones
  • The Cameo: In 100 Days Of The Doctor Six and Evelyn are sidetracked by being sucked into this alternate universe. Though we don't see what happened, this Doctor and the Brigadier helped them save the day.
  • The Chains of Commanding: For most people mistakes are soluble or something that can be lived with. It weighs on him that his new job as President of the Universe means that for him a mistake can result in an apocalypse.
  • The Chessmaster: He and Alistair are extremely at home with military tactics.
    • At the conclusion of The Ruler of The Universe boxset it's revealed he arranged a series of events ranging from the Master trying to summon an ancient evil to ensuring his own impeachment in order to save (most) of his universe, leave the Master in a job he hates with the Mother Superior to keep him in line and most impressively get Bernice back to her home universe.
  • Deadpan Snarker: The older he gets, the snarkier he becomes.
  • Deal with the Devil: In his first two appearances, this Doctor makes a deal with the Master and the Daleks respectively. He gets called out on it both times, but is wary of the Master in the first place, and the Daleks are much more reasonable(ish) in this altered universe.
  • The Dreaded: Played for Laughs. His reputation for always winning coupled with sudden fame from being President of the Universe means that the assorted villains he challenges keep surrendering the moment he turns up. He's delighted when he finally encounters someone who drugs and imprisons him but even then keeps dragging out the conflict just to get some excitement.
  • The Exile: The Time Lords tried to do this to the Doctor, much like his canonical version. Luckily, a well-placed nuke kicks the TARDIS back to normal. Amusingly, perhaps out of spite, the Doctor's exile was simply being given a limiter that kept it from moving through time, or away from Earth (with, of course, the Doctor's knowledge of how to fix this ripped from his head) rather than being stripped from knowing how to work the TARDIS at all.
  • The Fettered: This Doctor very calmly states that his job is to protect the oppressed. If the Daleks want him to stop fighting them, they should stop being the oppressor.
  • For Want of a Nail: All because this Doctor wasn't around in the Seventies (or was it the Eighties?), the world has become surprisingly dark and horrible. Mankind certainly still exists, so UNIT has done their job the best they can even without the Doctor, but the world shows its scars. Much of downtown London, for example, has been replaced by a rather large crater thanks to UNIT thwarting a plan to wipe humanity from existence to replace them with dinosaurs. The plastic purges of the 1970s are another perfect example, although strangely, Stahlman's Gas is considered a hot commodity and quite useful.
  • I Warned You: An extremely dark version while wandering the ruins of what is presumably his Gallifrey. He screams out something he's always wanted to say to the Time Lords, "I TOLD YOU SO!". It's implied that his universe's version of the Last Great Time War was born from the Time Lords being attacked by the rest of the universe for refusing to share their powers. He advised that they should stop the war by agreeing to share their power, but even while losing they refused to do so. (One wonders if it's because in this universe, the Fourth Doctor never met Romana, who'd go on to found the Temporal Powers Alliance and liberalise Gallifreyan society.)
  • Jade-Coloured Glasses: By the time he meets Benny Summerfield, he's ready to jump ship and leave the universe altogether. He's seen it all, done it all and gotten fed up with it all.
  • Last of His Kind: Unlike in the main universe this Doctor (and Master) became the last of their kind a little earlier in their lives. And their Time Lords are very definitely, permanently dead.
  • Lighter and Softer: This Third Doctor is a whole lot nicer than Pertwee (though just as snarky), thanks to his exile only lasting a few hours, as opposed to a few years.
  • Manipulative Bastard: A well-meaning but still somewhat harmful example. When he discovers his therapist never had a family he tries to be kind by going back in time and ensuring her fiancé won't die so when he talks to her in the present she is not only Happily Married but also she has had Babies Ever After. However when she discovers this she is furious with him for completely altering her life without her knowledge.
  • Nice Shoes: In a stinger following Sympathy for the Devil, the Doctor takes the time to complain that his shoes don't fit at all.
  • Not That Kind of Doctor: Actually subverted somewhat in "Sympathy for the Devil" in that the Doctor uses it as an excuse to get close to an injured man to obtain more information.
  • Quintessential British Gentleman
  • Refuge in Audacity: This Doctor, perhaps inadvertently, engages in this a lot in his plans. They tend to work quite well.
  • Refusal of the Call: He accidentally ends up President Of The Universe, by virtue of having defeated everyone else who wanted a go at it. He's not happy about it.
  • Shell-Shocked Veteran: His universe's version of the Time War left him with a lot of scars, not the least of which is he sacrificed whole chunks of his memory as part of whatever he had to do to end it.
  • There Are No Therapists: Or rather there are no therapists who can begin to understand what you're dealing with. He gets a therapist in Asking for a Friend. It doesn't go well (see above). Even when he finally confesses he's terrified by the prospect of the countless billions who will die if he makes any mistakes and the massive amount of guilt and various trauma he is constantly coping with it causes his therapist to admit she cannot help him.
  • Trapped in Another World: Enters the main universe, with no apparent way back to his own, along with Bernice Summerfield at the end of The True Saviour of the Universe.
  • What the Hell, Hero?: ...teaming up with Daleks? Even the Brigadier calls the Doctor out on this one, although the Daleks actually aren't nearly as bad in this universe. (Since the Fourth Doctor never existed, he never interfered in the Genesis of the Daleks, and Davros ended up developing his creations in a slightly different direction.)
  • Worthy Opponent: The Daleks start listening to Doctor's plans more when they realize just who he is.

     Alternate Future Doctor (David Collings) 

Alternate Future Doctor

Voiced by: David Collings (2003)

"If I told you I'd have to kill you."

Time has passed for this Doctor, who has but a few regenerations left, and time has hardened him quite a bit. Stranded on Earth and with unfinished business waiting for him at the bottom of the ocean, this incarnation no longer plays nice. Only appears in the audio drama "Full Fathom Five".

  • Combat Pragmatist: Has no problem murdering people with one clean shot, if it's necessary.
  • Downer Ending: He's trapped in the bottom of an undersea base and the woman who he adopted as his daughter has just killed him. And she's going to keep killing him until his regenerations are all spent and gone. On the other hand, though, his daughter actually kinda has a point.
  • It's All About Me: This Doctor not only kills people with relatively limited justification, but it's implied that he would have let his unofficially adopted daughter think he was dead just so that he can retrieve the TARDIS.
  • Knight Templar Parent: The Doctor has little problem with risking his own life, but he absolutely refuses to let his adopted daughter Ruth do the same.
  • Not-So-Well-Intentioned Extremist: The Doctor basically argues that his actions are always justified, but when he kills a man just on the chance that another scientist's work will be continued based on analysis of the man's condition, it's hard not to feel that other Doctors would have been more willing to take a risk in the name of an innocent life.

     Alternate Valeyard (Michael Jayston) 

Alternate Valeyard

Voiced by: Michael Jayston (2003)

"Don't call me the Doctor."

Only appearing in "He Jests at Scars", this alternate Valyard is the end result of what might have happened had the Valeyard actually won the events of The Ultimate Foe, thus becoming the Doctor himself. Rather than gallivant around the universe like the Doctor would normally do, this Valeyard-Doctor instead decided to run around, blowing everything out of existence — eventually killing every single one of his previous incarnations.

  • And I Must Scream: This Doctor was finally defeated (technically) by a Future Badass version of Mel. Doomed to spend an eternity in the TARDIS control room (the only remaining aspect of reality left), unable to move or even do much more than breathe or think while reality slowly sorts itself out. Maybe.
  • And Then What?: So the Valeyard defeats the Sixth Doctor in the Matrix, secures immortality for himself and becomes ruler of his own city in the time vortex. What now? Uh... kill more Doctors, I guess?
  • Byronic Hero: His selfish mission to become "real" causes problems for both himself and the entire universe at large.
  • Didn't Think This Through: Accurately summarises his whole misadventure after "winning" the Trial of the Time Lord. After killing various past incarnations of the Doctor, his attempts to rectify the increasingly unstable timeline only continue to escalate the problem, as he keeps failing to anticipate the near-omnipresent impact that the Doctor had on the universe.
  • Enemy Without: This alternate version is explicitly said to be the Doctor's Watcher, which is usually a ghostly manifestation of a future regeneration as seen in "Logopolis", that somehow gained independent consciousness.
  • Evil Counterpart: Subverted for perhaps the only time in the franchise, seeing how he's finally the real article.
  • Evil Feels Good: At least, at first.
  • Hoist by Their Own Petard: His reckless, wanton fuckery with the space-time continuum eventually ruins reality so thoroughly that he is last seen petrified in a corner of the TARDIS, so terrified of ruining the timestream further that he can't let himself move a muscle.
  • Kill 'Em All: He can perhaps lay claim to being the first, though surprisingly not quite the last, villain in Doctor Who history to utterly destroy the universe and all life in it, albeit in his own self-contained parallel universe.
  • Large Ham
  • Lotus-Eater Machine: The TARDIS becomes one to him, projecting comforting illusions of him gaining godlike powers and wiping out the Time Lords to distract him from the universe's approaching annihilation.
  • My God, What Have I Done?: He only realises far too late the damage his reckless actions have caused and can only apologise sincerely to Mel as the last vestiges of reality crumble around them.
  • Survivor Guilt: Considering the ending, this one actually makes sense.
  • With Great Power Comes Great Insanity: After assuming control of what's left of space-time, the Doctor-Valeyard can literally do whatever he desires. This is, of course, because it's all an illusion.

     Alternate Third Doctor (Arabella Weir) 

Alternate Third Doctor

Voiced by: Arabella Weir (2003)

"I hate trolleys! They're just Daleks without the interesting bits."

A female Doctor who came about after the Second Doctor (voiced here by Nicholas Briggs) killed himself and escaped to avoid the trial at the end of "The War Games". Realising the CIA won't find her as long as she lies low, she gets a job pushing trolleys at Sainsbury's and falls into a life of drunkenness and ennui. Appears in "Exile".


     Alternate Eighth Doctor (Paul McGann) 

Alternate Eighth Doctor a.k.a. Johann Schmidt

Voiced by: Paul McGann (2010)

A Doctor from an alternate timeline, where the Seventh Doctor, Ace and the TARDIS were captured in Colditz Castle and the Nazis wound up winning World War II as an accidental aftereffect. After being killed and regenerating, the (now) Eighth Doctor spent decades manipulating the Nazis and trying to reset the timeline. Was first mentioned in the audio "Colditz", and much later properly appeared in the mini-episode "Klein's Story".

  • The Atoner: This alternate Eighth Doctor spends pretty much his entire regeneration trying to correct time to its proper course. It's up to interpretation if he's trying to atone for the corruption of the timeline, or if he's trying to prevent Ace's untimely death by meddling. Probably both.
  • The Chessmaster: "Johann" spends over 10 years just trying to find a person whom he can potentially convince to step back in time and correct things. He then spends the next several months slowly convincing her to go back in time to "save" the Doctor from the original timeline on the pretense of using him to explain how the TARDIS works. He's good.
  • Faking the Dead: Done quite easily, considering he regenerated into another body.
  • Heroic Sacrifice: "Johann" gets at least shot trying to get Klein into the TARDIS, not to mention essentially erased from history once his plan works.
  • Temporal Paradox

     Alternate Doctor (Colin Baker) 

Alternate Doctor a.k.a. Lord Burner

Voiced by: Colin Baker (2011)

An incarnation of the Doctor living on an alternate-timeline Gallifrey, seen in series 4 of Gallifrey. In this timeline, there exists a Temporal Intervention Agency instead of a Celestial Intervention Agency, with a habit of retconning events and people out of history and gravely altering their timelines. This Doctor was dragged back to Gallifrey for his own equivalent of the Sixth Doctor's trial and forcibly rehabilitated into Time Lord society.

  • Badass Long Robe: He wears full Time Lord regalia.
  • Cain and Abel: With Braxiatel.
  • Loss of Identity: His life was altered by the TIA and shaped into something more suitable for Gallifreyan society.
  • Retired Badass: He's living a quiet, inconspicuous life on Gallifrey. Or so it seems. He's actually the Lord Burner, the Lady President's personal Professional Killer.
  • Temporal Paradox: Once he enters the Axis of Time. A killer and his victim can't exist in the Axis simultaneously, even if they're from different realities. This Doctor had, long ago, killed his timeline's version of Braxiatel.
  • Uncertain Doom: Last seen dragged into a portal by Braxiatel.
