Theory:Timeline - Multi-Doctor stories

This timeline lists every Multi-Doctor story in which two or more incarnations meet or appear in close proximity to each other in the order in which each incarnation of the Doctor experienced them, with an analysis of their state in the Doctor's memories.

Stories in bold indicate that the incarnation being focused on is the most recent incarnation in that story.

First Doctor

 * TV: The Three Doctors
 * The First Doctor is summoned by the Time Lords to assist the Second and Third Doctors in their battle with Omega, but becomes trapped in a time eddy. Shortly after the event, the First Doctors is vaguely able to recall having met "a dandy and a clown". (PROSE: The Empire of Glass)


 * TV: Twice Upon a Time
 * Set during the end of The Tenth Planet, the First Doctor, adamant that he does not want to change, holds off his regeneration long enough to meet the Twelfth Doctor. The First Doctor learns about a significant amount of his future, and ultimately goes through with his regeneration with the knowledge that his future is in safe hands, with his memories of the encounter supposedly dying with his old body.

Third Doctor

 * PROSE: The Christmas Inversion
 * The Third Doctor is pulled into the events of The Christmas Invasion, where he searches for the Master while the Tenth Doctor is aboard the Sycorax ship. He meets Jackie Tyler, learns that he is destined to take on a "Rose" and "Mickey" as companions, and even indirectly aides his successor in completing his recent regeneration. The Doctor does not appear to retain this information, not recognising Rose, Mickey, or Jackie upon their first proper meeting in Rose, and with the Tenth Doctor believing the vapour from some tea that Rose and Mickey had spilt in the TARDIS to be the key to his recovery.

Ninth Doctor

 * TV: The Day of the Doctor
 * The Ninth Doctor teams up with his other selves to save Gallifrey at the end of the Last Great Time War. Indeed, this incarnations fresh guilt at his previously-assumed actions are temporarily alleviated, but ultimately forgotten.


 * COMIC: Four Doctors
 * The Ninth Doctor entertains Rose at a Paris cafe, unaware that he is being observed by his Tenth, Eleventh and Twelfth incarnations nearby.


 * COMIC: Endgame
 * The Ninth Doctor teams up with his eight numbered predecessors and two immediate successors to defeat the Master and Adam Mitchell.

Tenth Doctor

 * PROSE: The Christmas Inversion
 * Set during The Christmas Invasion, the Tenth Doctor recovers from his recent regeneration by unknowingly syphoning regenerative energy from a nearby Third Doctor. The Tenth Doctor believes his recovery to be an affect of the vapour from some tea that Rose and Mickey had spilt.


 * TV: The Day of the Doctor
 * The Tenth Doctor directly encounters his War and Eleventh incarnations, who later all team up with their other incarnations to save Gallifrey at the end of the Last Great Time War. The Tenth Doctor temporarily becomes aware of the truth as to what happened at the end of the war, and reevaluates his opinion of the War Doctor. As his immediate successor affirmed, the Tenth Doctor would lose his memory of these events due to the de-synched time streams. Nonetheless, he would still remember marrying Queen Elizabeth in The End of Time.

Eleventh Doctor

 * COMIC: Time Trick
 * Both the Eleventh and First Doctor are invited to a fake Time Conference on Refkeet Nine. The Eleventh Doctor sees that his predecessor is there, and keeps out of his way.


 * TV: The Day of the Doctor (in 1562 and in the Black Archive)
 * The Eleventh Doctor encounters his Tenth and War incarnations...


 * TV: The Day of the Doctor (saving Gallifrey)
 * The three of them go on to team up with their predecessors to save Gallifrey at the end of the Time War. They are also, unbeknownst to them, being aided by the Twelfth Doctor.


 * TV: The Day of the Doctor (in the Under Gallery)
 * Shortly after parting company from his two predecessors, the Eleventh Doctor meets the Curator in the Under Gallery, who all but confirms to him that their attempts to save Gallifrey were successful. The Eleventh Doctor supposedly comes away from the encounter with no memory of it, but "with the strange, groundless conviction that Gallifrey is still out there".


 * TV: Deep Breath
 * Set during the ending of The Time of the Doctor, the Eleventh Doctor, shortly before his regeneration, calls Clara Oswald in the near future to convince her to stay with his successor. Said successor is waiting for Clara nearby, allowing the conversation to play out, aware that his predecessor is on the other end. The Eleventh Doctor briefly learns through this exchange, to his chagrin, that his next incarnation is "old".

Twelfth Doctor

 * TV: The Day of the Doctor
 * The Twelfth Doctor lends his aide to his predecessors efforts to save Gallifrey at the end of the Last Great Time War. His predecessors are seemingly unaware of his involvement.


 * TV: Deep Breath
 * The Twelfth Doctor stands nearby as Clara Oswald receives the phone call from the Eleventh Doctor during the events of The Time of the Doctor.


 * WC: Doctors Assemble!
 * The Twelfth Doctor takes part in a conversation, set up by the Fourth Doctor, with all of his predecessors and immediate successor via the TARDIS telepathic circuits.

Thirteenth Doctor

 * TV: Fugitive of the Judoon
 * The Thirteenth Doctor encounters an unknown incarnation of herself who had been living under the Chameleon Arch identity of "Ruth Clayton". She has no recollection of this incarnation, but nonetheless identifies her as being in her past. The fact that the Doctor retains her memory of "Ruth" in following stories reinforces this notion.


 * COMIC: A Little Help from My Friends
 * The Thirteenth Doctor encounters the Tenth Doctor during the events of Blink.


 * WC: Doctors Assemble!
 * The Thirteenths Doctor takes part in a conversation, set up by the Fourth Doctor, with all of her predecessors via the TARDIS telepathic circuits.
