The Doctor, or Doctor Who, was the chosen nom de plume of a half-gallifreyan, half-human Time Lord from the baseline Whoniverse. The most emblematic of the Renegade Time Lords, the Doctor traveled throughout time and space aboard a TARDIS in pursuit of knowledge and adventure.


Personality and CharacterEdit

Considered a genius even among Time Lords, the Doctor is a never-ending well of kindness and benevolence, to whom his great age and many travels have granted much wisdom. On a darker note, though it takes much to arouse the Doctor's hatred, the results of his ire are devastating and unforgiving. The Doctor hates to admit defeat, and has often been observed to clam up or outright lie wherever his personal feelings are concerned. 

Abridged BiographyEdit


The son of a high-born Gallifreyan Time Lord called Ulysses and the Human Time LadyPenelope Gate, the Doctor ran away when first faced with the Untempered Schism, but was nonetheless enrolled at the Time Lord Academy and achieved the rank of a Time Lord. During his schooling says, the Doctor, who was known as Theta-Sigma, became friends with several other Time Tots, including two who would later become his enemies: the Master and the Rani. At some point in his youth, the young Doctor became stranded within the Cloisters, and, from the Cloister Wraiths, heard the story of the Hybrid; forever after, he would fear that he was the creature of prophecy. 

Life on GallifreyEdit

After graduating from the Academy, the Doctor  took a wife, a Time Lady called Patience, with whom he had several children. Rising high among the ranks of Time Lords, he became a respected authority, and brought an end to the use of Miniscopes in what may have been his first display of heroism. However, as time went on, he grew more and more dissatisfied with the Time Lord society's policy of non-interference into the affairs of other times and planets. Finally, a short time after he was offered the presidency of Gallifrey, the Doctor was moved to flee the planet together with his granddaughter Susan, taking the Hand of Omega with them to keep it safe from those who would misuse it. To make their escape, the Doctor and Susan stole a "rickety old TARDIS" from a repair workshop, which, despite its disfunctionalities, he found "the most beautiful thing in the world". The Doctor would go on to develop a deep bond with the TARDIS in question

An Adventure through Time and SpaceEdit

For hundreds of years and over several incarnations, the Doctor traveled through time and space, learning what he could and helping the locals whenever he encountered danger and evil. Having developed a special kinship with the planet Earth, he limited many of his travel to its past and future, took to having human traveling companions (starting with Ian Chesterton and Barbara Wright), and progressively became Earth's go-to protector against non-terrestrial incursors less benevolent than he. He found himself most often antagonized by the Daleks, the warmongering residents of the planet Skaro, and their creator Davros, though he also roused the enmity of the Cybermen, of his old friend the Master, and of many more. 

The Last Great Time WarEdit

Though he had had a rather trying relationship with the Time Lords of Gallifrey throughout his centuries of travels, the Doctor (then his eighth incarnation) was enrolled in the Time War which eventually broke out between the Time Lords and the Daleks. Pushed nearly over the edge by the trials of this war, the Doctor was forevermore ashamed of the terrible actions he had been forced to take in the War, choosing to cast an incarnation of himself who had lived through (and only through) the war out from his memory and from the numbering of his incarnations. Towards the end of the War, this incarnation, who was nearing death himself from old age and weariness, took the drastic decision of awakening the Moment to destroy Gallifrey, obliterating the Time Lords and Daleks both and putting a final end to the War. 

Return to AdventureEdit

Though later incarnations of the Doctor were eventually able to alter the course of history in this instance, making it so that Gallifrey had only ever seemed to be destroyed, the Doctor lived for hundreds of years with the guilt of having wiped out his own people in cold blood, which did considerable damage to his psyche. Nonetheless, from his ninth "official" self onwards, the Doctor returned to his old ways of traveling through time and space, fighting evil and righting wrongs, alongside a variety of companions (a few of the most influential being Rose Tyler and Clara Oswald). In this part of his life, the Doctor fell in love and married fellow time traveler River Song and was forced to witness her tragic death. In thanks for saving Gallifrey, his eleventh incarnation, which would have been his last in a traditional Regeneration Cycle, was granted a fresh set of apparently-limitless regenerations, with the first being his twelfth self

Distant FutureEdit

A future incarnation of the Doctor, over five million years old (in a count that glosses over the billions of years he spent inside his Confession Dial), was still adventuring inside the TARDIS, and, in an unusually silly turn of events, antagonized a villainess known as Crayola in the company of a rather inept companion called Fiona. Later still, the Doctor, having finally figured out how to control his regenerations, decided to revisit a few of his favorite past faces. In a form identical to his fourth, the Doctor retired, becoming the curator of the Under-Gallery in London and being known, accordingly, as “the Curator”. The Curator was prone to reminiscing about his previous adventures and incarnations, and, if he felt it safe to do so, did not shy away from disclosing them to whoever asked. 



As he was a Time Lord by birth and training, the Doctor possessed the ability to regenerate, changing his looks and temper while keeping his memories and core personality intact. He did not do so a mere 12 times as most Time Lords must, but was instead granted an extended regenerative cycle by Rassilon while on the brink of true death in Trenzalore, allowing him to have an apparently infinite number of regenerations.

As typical of Time Lord philosophy, the Doctor, at different points of his life, was uncertain whether each of his incarnations was an independant individual with a finite lifespan who merely shared the previous Doctors' memories, or merely an aspect of his true self who had but an illusion of individuality. While initially keen on the latter, incarnations of the Doctor past his eighth tended to favor the former. He even took to mentally simulating conversations with some of his past selves, valuing "their" insight; for instance, the Twelfth Doctor once had an extensive "conversation" with his fourth self.

Perhaps to stress each new incarnation's individuality, the Doctor tended to pick an "iconic" outfit early on in each incarnation and wear it evermore. It was usually a rather momentous occasion, marking a significant psychological change, if a given incarnation of the Doctor significantly overhauled his dress.  

Incarnations in Chronological OrderEdit

The person he was at birth, known for being quite cantankerous, yet kindly and affectionate to those closest to him, such as his granddaughter Susan.
The First Doctor regenerated into the Second Doctor due to the sheer weariness of his aged body.
(Played by William HartnellRichard HurndallDavid Bradley.)
The Doctor's first post-regeneration incarnation, the Second Doctor was far more approachable than the First, appearing as a warm, bumbling, and occasionally clownish middle-aged man with black hair. 
After being put on trial by the Time Lords of Gallifrey for breaching their laws of non-interference, the Second Doctor was exiled to 20th century Earth and they forced him to regenerate into a form of their choosing. The Doctor resisted this forced change, and ended up stuck in-between, becoming the Second-and-a-Halfth Doctor
(Played by Patrick Troughton.)
The sorry result of the Time Lords' attempt to force a regeneration on the Doctor, this "botched" incarnation was stuck somewhere in-between the Second and Third Doctor in both appearance and personality, though this did not prevent him from going on a few adventures. 
After a harrowing experience battling Daleks, the Doctor was greeted by a time-traveling version of his next incarnation, who shared a few words of wisdom with him and then left him to finally complete his regeneration into the Third Doctor. 
(Played by Tony Garner.)
Spending a significant part of his life in forced exile on Earth, the Third Doctor was a distinguished "older gentleman" type who seemed to particularly enjoy tinkering with his gadgetry. Growing wise with age, he gladly shared his wisdom with those who asked, but had a short patience for fools. 
After exposing himself to lethal levels of radiation in an attempt to bring down the alien queen known as the Great One, the Third Doctor died in the arms of his companion Sarah Jane Smith, regenerating into the Fourth Doctor
(Played by Jon Pertwee.)
Renewed and rejuvenated, this version of the Doctor was considerably more fun-loving and adventurous than his grim predecessor. A lovable oddball, he delighted in confusing everyone around him with his off-kilter sense of humor. The Fourth Doctor was a man of many habits and quirks, the most famous being offering jelly babies to most everyone he met. 
After repeatedly sighting an entity known as the Watcher, believed to be a decaying version of his own future self come to avert a catastrophic timeline, and whom he believed to herald his impending death, the Fourth Doctor met his demise by falling off a great height, and merged with the Watcher to regenerate into the Fifth Doctor.
(Played by Tom BakerJon Culshaw.)
Younger in mind and body than any of his predecessors, this incarnation of the Doctor was a more subdued sort of individual than most; a tea afficionado and cricket enthusiast, the Fifth Doctor was kindly and honorable to a fault, highly valuing fair play in his dealings with even his enemies; 
While fighting the Master, the Fifth Doctor and his companion Peri Brown were intoxicated by Spectrox. Only able to procure one dose of antidote, the Doctor sacrificed himself to save Peri's life, but, despite his uncertainty as to whether the Spectrox would prevent his regenerating, managed to pull through and regenerate into the Sixth Doctor
(Played by Peter Davison.)
An assertive younger man with a melodramatic air, a stubborn streak londer than his Fourth self's scarf, and an apalling fashion sense, the Sixth Doctor had a silver tongue with which to deal down biting sarcasm at those he considered beneath him. Nonetheless, like all of the Doctor's selves, he concealed a virtuous, empathetic set of hearts beneath his unpleasant persona. 
While fighting his old nemesis and fellow Time Lady the Rani, the Doctor suffered a severe concussion to the head as he steered his TARDIS, and regenerated into the Seventh Doctor
(Played by Colin Baker.)
A Doctor finally at peace with himself, the Seventh Doctor was a self-declared man of mystery, who often formulated schemes upon plots upon riddles which he did not tell even his most trusted companions about. The motif of question marks with which he emblazoned his entire wardrobe rather tackily stressed this aspect of the Time Lord. This did not mean that he was grim or bitter; in fact, he was a rather debonnair fellow with a buffoonish sense of humor. 
After receiving light injuries on one of his adventures, the Seventh Doctor was mistakenly taken into a hospital's custody, where the misled "care" of the physicians who thought him to be a human nearly killed him. In the end he traumatically regenerated into the Eighth Doctor
(Played by Sylvester McCoy.)
The Eighth Doctor, freed of the worries of his past by his rather definitive defeat of the Master (the scum's eventual escape notwithstanding), was able to return to his roots as a happy, care-free adventurer and explorer. In this form, the Doctor was highly emotional, and repeatedly fell in love with female companions of his. Though he appeared to have once regenerated into a completely different man, this timeline was cancelled by the Last Great Time War, in which the poor Doctor, back to his Eighth incarnation with only dim recollection of the Ninth, found himself dragged against his will.
His spirit broken and his body almost annihilated in a spaceship crash on Karn, the Doctor was convinced to give up on peace become a warrior by Ohila, and artificially forced his regeneration into a suitable form — the War Doctor.
(Played by Paul McGann.)
A morose genius with an angry disposition, this version of the Ninth Doctor from an aborted timeline was reluctantly ordered about the universe by the other Time Lords, who had retreated into a parallel dimension. 
As a result of the damage dealt to the timeline by the Time War, this Doctor ceased to exist as his version of time was erased; instead the Eighth Doctor forced a regeneration into the War Doctor. Nonetheless, later incarnations of the Doctor retained memories of this period of his life. 
(Played by Richard E. Grant.)
His body and temper designed by the Sisterhood of Karn to be a Warrior, this incarnation of the Doctor forsook the name of Doctor for most of his life, though others persisted in calling him so. He fought valiantly but practically throughout the Time War, forced to do many a horrible thing, culminating in his desperate decision to use the Moment to destroy Gallifrey altogether, wiping out the Daleks and Time Lords in one fell swoop. 
In a piece of timeline which he was unable to remember due to a paradox, the War Doctor cooperated with his future selves to "fake" Gallifrey's destruction while actually preserving it in a pocket universe. Shortly after, his destiny having run its course and his old body getting battered, the War Doctor peacefully regenerated into the Ninth Doctor
(Played by John Hurt.)
Haunted by the recent wound of his actions as the War Doctor, and particularly what he believed to be the genocide of his own people by his own hand, the Ninth Doctor was a darker, broodier, ruder man than the Doctor had ever been. Yet still he ran and fought and rescued on the planet Earth, with his companion Rose Tyler as the singular ray of sunlight in his bitter life. 
His body irreparably damaged by briefly absorbing the raw energy of the Time Vortex into himself, the Doctor regenerated rather smoothly into the Tenth Doctor in front of a rather confused Rose.
(Played by Christopher Eccleston.)
Still reeling from being (as far as he knew) the Last of the Time Lords, the Tenth Doctor nonetheless managed to appear far more outgoing and youthful than the Ninth. A "swashbuckling adventurer" type, he had a tendency to go mad with the power invested in him by being the sole wielder of Time Lord technology in the universe, something he would then invariably come ot regret. 
After expending one dose of regeneration energy in the creation of the Metacrisis Doctor, the Tenth Doctor once again found himself in life-threatening danger, forced to expose himself to lethal levels of radiation to save Wilfred Mott. He tearfully regenerated into the Eleventh Doctor
(Played by David Tennant.)
Young and bouncy, exuberant and adventurous, the Eleventh Doctor was still reckless and unpredictable, but the mistakes were all his own; he seemed to have largely put the trials of his previous incarnations behind him. It was in this body that he most often adventured with River Song, and that he met Clara Oswald
After hundreds of years of resisting in Christmas against a coalition of his enemies, the Doctor reached the absolute end of his body's lifespan. Granted a new regeneration cycle by the Time Lords, he explosively regenerated into the Twelfth Doctor.
(Played by Matt Smith.)
The first "old" Doctor in a long time, the Twelfth Doctor returned to being darker and more guarded, though he retained a dose of eccentricity. Still, the Twelfth Doctor had a stern, commanding air about him, whatever he did. When pushed to his limits (as he was by the loss of Clara Oswald), the Twelfth Doctor had the potential to become terrifyingly ruthless. 
After battling the Master and the Cybermen of Mondas one last time, and going on a time-crossed adventure with his first self, the Doctor peacefully regenerated into the Thirteenth Doctor
(Played by Peter Capaldi.)
A lean woman with short blond hair, the Thirteenth Doctor had a cheery, outgoing disposition.
At some undisclosed point, the Thirteenth Doctor faced life-threatening injury and regenerated into a different Doctor. 
(Played by Jodie Whittaker.)

Future RegenerationsEdit

It is known that the Doctor will regenerate into these individuals at some point in his future, but their actual numbering is unknown. 

Courageous and brilliant, but also, at times, surprisingly absent-minded and childlike, this old-looking incarnation of the Doctor was once kidnapped by the Celestial Toymaker and forced to relive streamlined version of his adventures as the First Doctor opposite the Daleks, while believing himself to be a human scientist who had created a "time machine" called "Tardis". He also had many adventures of his own.
Unless he is the final incarnation of the Doctor, this Doctor presumably suffered a life-threatening injury at some point and regenerated into another incarnation.
Calm, well-dressed and distinguished, and at long last blessed with fiery red hair, this future incarnation of the Doctor was characterized by his great patience when faced with fools, even if they were his enemies.
Unless he is the final incarnation of the Doctor, this Doctor presumably suffered a life-threatening injury at some point and regenerated into another incarnation.
(Played by Mark Gatiss.)
Cheerful and warm, this rather plump, long-haired future Doctor (over five million years old in a count that probably skips over his billions of years inside the Confession Dial) fought the alien evildoer Crayola
Unless he is the final incarnation of the Doctor, this Doctor presumably suffered a life-threatening injury at some point and regenerated into another incarnation.
(Played by Jim Broadbent.)
An incarnation of the Doctor from the distant future, who had figured out how to once again regenerate into the same form as his fourth self, the Curator retired from adventuring and lived a quiet life in London, becomign the Curator of the Under-Gallery. He liked to reminisce about his older adventures. 
Unless he is the final incarnation of the Doctor, the Curator presumably neared death from old age and regenerated into another incarnation, one who may have once again taken up adventuring. 
(Played by Tom Baker.)

Other DoctorsEdit

Over the course of his long life, the Doctor was mixed up with many strange happenstances which created splits or clones of himself through other methods than regular Time Lord Regeneration. They include:

A short-lived clone of the Fourth Doctor created by Kilbracken technology, this Fourth Doctor shared the original Doctor's memories and was connected to him through a psychic link. 
This Doctor dissolved into nothing as a consequence of his pre-set lifespan running out.
(Played by Tom Baker.)
A partial clone of the Tenth Doctor born from excess regeneration energy, the Metacrisis Doctor also ’absorbed‘ part of Donna Noble during his inception, adopting some human physiology (such as a single heart) and a few personality traits of Donna's. This Doctor later ended up stranded in Pete's World.
(Played by David Tennant.)
A hybrid being created together with the Metacrisis Doctor, the entity known as the DoctorDonna resulted from the human Donna Noble absorbing traits from the Tenth Doctor — part of his brain overwriting hers, granting her his technical genius and some of his personality and knowledge. The entity was short-lived, as the real Doctor found himself forced to erase the DoctorDonna's memory, returning Donna Noble to normal (though without any memory of who the Doctor was at all).
(Played by Catherine Tate)
An embodiment of the Eleventh Doctor's darker thoughts and impulses given a will and mind of its own by an alien hallucinogen, the Dream Lord had power over the dreams of those placed under said hallucinogen, but was reduced to a mere inner demon with no reach to the physical world after the Doctor woke up. 
(Played by Toby Jones.)
An identical Ganger copy of the Eleventh Doctor (minus the ability to regenerate), the Ganger Doctor assisted his original self on an adventure, and was last seen dematerializing himself thanks to a Sonic Screwdriver
(Played by Matt Smith.)
Mister Clever was the result of Cyber-Planner software partially taking over the Eleventh Doctor's brain. After almost succeeding in fully converting the Doctor, Mister Clever's consciousness was ejected from the Doctor's mind and then destroyed alongside the other Cybermen on the planet.
(Played by Matt Smith.)
A digital simulation of the Twelfth Doctor created by the Monks in their "Shadow World" artificial reality, the Shadow Doctor, initially unaware of his true nature, was hunted down over and over again by the Monks so that they could better learn how to kill the real Doctor. In the end he managed to figure out what he was and sent a message to the real world, warning the real Doctor of the Monks's nefarious plans.
(Played by Peter Capaldi.)
A mysterious being created at some point in the Doctor's timeline posterior to the Twelfth Doctor incarnation, the Valeyard was an amalgamation of the Doctor's dark side (much like the Dream Lord), given physical form but not the ability to regenerate.
(Played by Michael Jayston.)
