The Thirteen Doctors

Birth: The Doctor is born on the planet Gallifrey under the sign of Crossed Computers. He lived in a house on the side of a mountain in southern Gallifrey.

While a young boy, he used to cry a lot and spent his nights alone in a barn away from his house. He is visited by his future companion Clara one night who comforts him and tells him "fear makes companions of us all". She then gives the young Doctor a toy soldier.

Age 8: The Doctor enters Time Lord Academy and stares into the Untempered Schism. During his time in the academy he was a Prydonian known as 'Theta Sigma' and was friends with the Master. He was taught by Azmael and Borusa and regarded the great criminal Salyavin as his childhood hero. He was quite a trouble student; having been expelled, failed TARDIS lessons and only passed his exams with a 51% on the second attempt. The Doctor looked up to the Hermit as his guru; the Hermit was a wise Time Lord who lived on the side of a mountain behind the house where the Doctor lived and who used to tell him ghost stories.

 He eventually received his doctorate and later on adopted a new name - "the Doctor" - as a vow to be "Never cruel or cowardly. Never give up, never give in".

Age 90: The Doctor visits the Medusa Cascade for the first time.

Age 236: The Doctor steals a faulty Type 40 TARDIS and leaves Gallifrey with the Hand of Omega and his granddaughter Susan. He would later say that he fled his homeworld out of boredom, but in truth it was because he feared a prophecy that a hybrid was destined to conquer Gallifrey and stand in its ruins.

The Doctor and Susan become renegades and go on to explore the universe.

Age ~296: The Doctor hides the Hand of Omega on Earth, 1963. Ian and Barbra become unwilling companions of the Doctor. The Doctor begins acquiring human companions.

Age 450: The Doctor is forced to regenerate due to exhaustion and a loss of strength to maintain his ancient body.

Age 453: The Doctor is put on trial by the Time Lords for breaking the Laws of Non Interference. He is sentenced to a forced regeneration and exiled to Earth. However, he is instead pulled out of time to work for the Celestial Intervention Agency.

Age ~500: The Doctor eventually regenerates into his third incarnation and exiled to Earth in the 1970s with the secret of time travel taken from him. He eventually finds himself working as UNIT's unpaid scientific advisor. The Time Lords later lift his sentence after helping them dealing with Omega.

Age 748: The Doctor regenerates into his fourth incarnation from radiation poisoning from the Great One's web of Metebelis crystals.

Age 750-760: The Doctor becomes Lord President of Gallifrey by default but abandons the title only to temporarily reclaim the title later on during the Sontaran attempt to invade Gallifrey.

Age ~800: The Doctor falls off the Pharos Project radio telescope and gets severely injured; with help from the Watcher (a manifestation of the Doctor) he regenerates into his fifth incarnation.

Age 900: The Doctor undergoes a traumatizing regeneration into his sixth incarnation after being exposed to unrefined Spectrox.

Age 953: The Sixth Doctor is put on trial by the Time Lords for a second time. After the trial, his TARDIS is attacked by the Rani where he then regenerated into his seventh incarnation due to head trauma. During his seventh incarnation he settled some unresolved business such as the Hand of Omega, Fenric and Nemesis.

Age ~1000?: His old friend/archenemy the Master is executed by the Daleks. The Doctor was taking his remains back to Gallifrey when he is forced to land on Earth. The Doctor regenerates into his eighth incarnation after arriving in San Francisco, 1999 and being lightly injured after being caught in the middle of a gang war; his circulatory system was then accidentally damaged by Dr. Grace Holloway. The Master resurrects and tries to steal the Doctor's remaining regenerations only to be sucked into the TARDIS' Eye of Harmony and destroyed.

Age ???: Throughout his eighth incarnation the Doctor lost track of his age. He continued to have many adventures throughout time and space. Eventually the Time War began to start between the Daleks and Time Lords; he tried to avoid fighting but eventually he was killed while attempt to save a woman named Cass from a crashing spaceship. The Sisterhood of Karn resurrected him and helped him regenerate. The Doctor had become jaded and decided that it was time to abandon his title as "Doctor" and become a warrior. He drinks a potion and regenerates into the War Doctor.

Age "~800": After years of fighting in the Last Great Time War, the War Doctor has become jaded and left with no choice. With the Daleks and Time Lords threatening the whole of creation, he decides "No More". He steals a weapon known as "the Moment", powerful enough to wipe out every Dalek and Time Lord in existence and attempts to activate it. The Moment shows him the consequences of performing this action by showing him the man he is going to become (tenth and eleventh Doctors). With help from his other incarnations, the Doctor devises a plan to try and lock Gallifrey away into a bubble universe while at the same time destroying the Daleks. The Doctor was unsure if he has succeeded doing the right thing, but assured himself that at least he failed doing the wrong thing. He then lost all memory of meeting his future selves, attempting to save Gallifrey and then regenerated into the ninth Doctor from old age.

Age "900": The ninth Doctor, ashamed of his actions in the Time War and believing that he destroyed Gallifrey, tries his best to forget his previous incarnation. He begins counting his age again and assumes his age is 900. He starts travelling with companions again. He then regenerated into the tenth Doctor after he removed the Time Vortex's energy from Rose Tyler, channelling it back into the heart of the TARDIS.

Age "903": The Doctor discovers the Master has survived the Time War. The Master steals the Doctor's TARDIS, becomes the British Prime Minister and takes over Earth. In the end the Doctor defeated him and put things back the way they were.

Age "904": The Doctor meets River Song for the first time on the Library where she dies saving the planet. The Doctor partially regenerates but does not change appearance after being shot by a Dalek. The Meta-Crisis and DoctorDonna is created from this process.

Age "906": The Master is resurrected yet again and attempts to take over the Earth. The Time Lords attempt to break the Time Lock and destroy all of time and causality. The Master and Doctor momentarily work together to send them back into the Time War. The tenth Doctor then sacrifices himself to save Wilfred and is poisoned by radiation. He starts regenerating into the eleventh Doctor.

Age "907": The Doctor reboots the universe after the Silence destroyed it by blowing up the Doctor's TARDIS and causing the cracks in time. He was almost erased from history but was saved when Amy Pond was able to remember him.

Age "1103": After his 200 year 'Farewell Tour' he was destined to be killed by River Song in an astronaut suit at Lake Silencio, Utah on April 22, 2011. The Doctor cheated death by shrinking down and and being inside the Tesselecta while it was assuming his form. The Doctor gets married to River Song and he tells her his name. The Doctor later continued his adventures with his in-laws Amy and Rory until losing them in New York during an incident with the Weeping Angels. He then spent the next hundred years travelling alone and not getting involved.

Age "~1200": The Doctor meets the enigmatic Clara Oswin Oswald in Victorian London who was exactly like a woman he met on the Dalek Asylum named Oswin Oswald. He then goes in search of another iteration of her in order to figure out who and what she is. He meets Clara Oswald in the 2013 and she becomes his companion. The Great Intelligence later lures the Doctor to his personal future - the Doctor's grave on the planet Trenzalore - in order to enter his timestream and kill the Doctor. Clara jumps into his timestream and is splintered into many iterations and scattered throughout the Doctor's life and saves him; she is then rescued by the Doctor. He later meets the War and Tenth Doctors where in short he devises a plan to attempt to save Gallifrey from being destroyed. He later learns from the Curator that he in fact did save Gallifrey and confirmed that it was locked away in a bubble universe. He then tracked down a signal the Time Lords were sending through a crack in time on the planet Trenzalore. Various alien species attempted to prevent the Time Lords from returning so they tried attacking the planet, but the Doctor stayed and defended it.

Age "~1500": The Doctor has been defending the people of the planet Trenzalore for 300 years and has started to age.

Age "~2100": The Doctor has been defending Trenzalore for hundreds of years now and only the Daleks remain. The Doctor can no longer regenerate and is withered and old; he is approaching death. At the last moment, the Time Lords grant him a whole new regeneration cycle through a crack in time. He regenerates into his thirteenth incarnation; the resulting burst of energy destroys the Dalek ships.

Age “2240”: The Doctor spends 139 years (1980-2119) in suspended animation at the bottom of a lake in Caithness, Scotland.

After Clara Oswald’s death, the Doctor is teleported and imprisoned inside his Confession Dial where over a period of approximately four billion years he is stuck in a recursive cycle of death and resurrection, reliving the same few days with no memory of his previous iterations over and over while being stalked by an entity called the Veil. At the end of each cycle the Doctor would punch at a wall made of solid Abzantium (a mineral 400 times stronger than diamond), die, and restart the cycle. He continued this for four billion years until eventual he was able to punch through the eroded wall and escape, finding himself on the planet Gallifrey.
