List of Doctor Who supporting characters

The Doctor is usually accompanied in his travels by one to three companions (sometimes called assistants). These characters provide a surrogate with whom the audience can identify, and further the story by asking questions and getting into trouble, (similar to Dr. Watson in the Sherlock Holmes mysteries.) The Doctor regularly gains new companions and loses old ones; sometimes they return home, or find new causes on worlds they have visited. A few of the companions have died during the course of the series.

1. Lethbridge-Stewart appeared as a regular in Seasons 7 and 8 and more sporadically in many other episodes. Nicholas Courtney, along with his role as Bret Vyon in The Daleks' Master Plan, his appearance in the charity special Dimensions in Time and his participation in the Eighth Doctor audio play Minuet in Hell, has the distinction of having acted with every screen Doctor before the Ninth and also the Tenth (although in adventures before actor David Tennant was cast as the Doctor).
2. The Inquisitor and The Valeyard appeared in every episode of Season 23, a season that comprised just one story, (albeit split into four segments), The Trial of a Time Lord.
3. Mickey Smith was a significant recurring character in the 2005 series, prior to briefly becoming a companion in the 2006 series. Similarly, Jackie Tyler appeared in many episodes of the 2005 and 2006 series; in the episodes "Army of Ghosts" and "Doomsday", she briefly travels in the TARDIS and acts like a companion, although she is not generally considered one.
4. The Master appeared as a regular in Season 8 and has returned numerous times in subsequent seasons and the television movie.
