List of multi-Doctor stories

A multi-Doctor story is a story featuring two or more different incarnations of the Doctor. There are several different ways a "multi-Doctor story" can be defined; here, stories are sorted according to several different definitions. This list includes stories with flashbacks, but excludes stories featuring only pictures or archive footage of other incarnations.

Note: Some stories fall into multiple categories. For instance, though the Ninth, Tenth, Eleventh, Twelfth, alternate Twelfth, and War Doctors appear in COMIC: Four Doctors, the Tenth, Eleventh, Twelfth, and alternate Twelfth Doctors interact directly; the War Doctor appears only in a flashback separate from the rest; and while the Ninth Doctor is in the same location as his three successors, he does not notice them. For the purposes of this list, Four Doctors is listed four times.

Direct encounters
In these stories, multiple incarnations of the Doctor encounter each other directly, either in person, through a screen, through a phone, through a psychic link etc. Italicised xs denote the Doctor(s) that did not directly encounter another Doctor.

Separate narratives
In these stories, multiple incarnations of the Doctor appear in the same story, but at least one does not encounter other incarnation(s) as they are in separate times and/or places. This including flashbacks and audio/video recordings of a separate incarnation.

Close Proximity
In these stories, multiple incarnations of the Doctor are in the same time and place, but do not encounter each other.

Manifestation
In these stories, multiple incarnations of the Doctor are in the same story, but some are manifestations inside the Doctor's mind, in a dream, created by the Matrix, in a video game etc.

(Bold x's denote the real incarnations in the story.)

Regeneration
In these stories, the Doctor regenerates into their next incarnation.

Retro-regeneration
In these stories, the Doctor temporarily retro-regenerates (i.e. is de-aged) into past incarnation(s).
