Doctor Who is a long-running British
science-fiction television series that began in 1963. It stars its protagonist,
The Doctor, an alien who travels through time and space in a ship known as the
TARDIS, as well as their travelling
companions. When the Doctor dies, they are able to undergo a process known as "
regeneration", completely changing the Doctor's appearance and personality. Throughout their travels, the Doctor often comes into conflict with various
alien species and antagonists.
In the show The Valeyard appears in all four segments of the 1986 story
The Trial of a Time Lord –
The Mysterious Planet,
Mindwarp,
Terror of the Vervoids and
The Ultimate Foe. During the events of the story, the
Sixth Doctor (
Colin Baker) is put on trial by his people, known as the
Time Lords, for interfering with history, which the Time Lords have an oath against doing. The Valeyard (
Michael Jayston) acts as the
court prosecutor in the trial, presenting evidence against the Doctor's innocence. As the serial progresses, it is revealed that the Valeyard tampered with evidence, allowing him to paint the Doctor in a negative light. The Doctor's old enemy
the Master (
Anthony Ainley) reveals that the Valeyard is actually a future incarnation of the Doctor, stated to be "amalgamation of the darker sides" of the Doctor's nature, from somewhere toward the end of the Doctor's life. The Valeyard has been working with the Time Lords to cover up their involvement in moving the planet
Earth from its proper place in the universe and killing nearly every human on the planet; as the Doctor discovered the Time Lords' actions in the past, they wanted to execute him under the pretence of a trial. In return, the Valeyard would have received the Doctor's remaining regenerations, extending the Valeyard's lifespan. The Valeyard had been planning to kill the Time Lords after they had given him this, however, and when his identity and plans are revealed to the court, he escapes into
the Matrix, a massive data repository for the Time Lords. The Master and the Valeyard are both seemingly trapped inside the Matrix and destroyed; the Doctor escapes, and the Time Lords allow the Doctor to leave, the charges against him dropped. As the Doctor leaves, the Valeyard is revealed to have escaped in disguise as another Time Lord.
In other media In the 1995
Virgin Publishing novel
Millennial Rites, the Valeyard briefly emerged from the Sixth Doctor's consciousness, taking over the Doctor's personality and actions, but is repressed by the Doctor. The 1997
BBC Books novel
The Eight Doctors sees the
Eighth Doctor return to an alternate version of the trial of the Sixth Doctor in which the Valeyard is about to execute him. The Eighth Doctor dismisses the evidence brought up by the Valeyard, and has an inquiry be held into the Valeyard's creation and the motivations behind the Sixth Doctor's trial, but the Valeyard disappears before anything can be determined. The 1998 novel
Matrix sees the Valeyard using the "Dark Matrix," the repository of all of the Time Lords' most evil impulses, and tries to use it to take revenge on the Doctor. The Valeyard is eventually killed by a lightning bolt being generated by the Valeyard's damaged
TARDIS as the Dark Matrix escapes the Valeyard's control. A novel from the late
Doctor Who author
Craig Hinton, ''
Time's Champion'', was intended to feature the Valeyard and elaborate upon the origins of the Valeyard. However, the novel was rejected by BBC Books. Co-writer Chris McKeon would go on to complete the novel upon Hinton's death and release it unofficially. The novel was edited and published by
David J. Howe as a benefit for the
British Heart Foundation. The 2003
Big Finish Productions'
Doctor Who Unbound audio drama He Jests at Scars... documents an alternative timeline in which the Valeyard has defeated the Doctor and gone on to ransack time and space. It is revealed, however, that he damaged time irreparably, and reality was collapsing, with the Valeyard too scared to even move, fearing he will damage the timeline more. He is eventually trapped in his TARDIS, unable to escape, until the end of time. Another Big Finish audio,
Trial of the Valeyard (2013), has the Valeyard captured and put on trial by the Time Lords. During the drama, the Valeyard claims he was created by the Doctor's final incarnation, who was experimenting with ways to break the regeneration limit. The Valeyard attempts to kill the Doctor but is thwarted and escapes, leaving the Doctor to contemplate the truth of the Valeyard's words. In the 2015 audio
The Sixth Doctor: The Last Adventure, the Valeyard masterminds a plot that will allow him to take control of the Doctor's body. Although the Valeyard's plan succeeds, the Doctor is able to manipulate events so that the Sixth Doctor is forced to regenerate, killing the Valeyard. The Valeyard re-appears in the 2019 audio
The War Valeyard, with the Time Lords deciding to utilise a copy of the Valeyard as a soldier in the Time War, an intergalactic conflict between the Time Lords and a race known as the
Daleks. The Valeyard is left trapped in a time loop fighting Daleks under the belief that he is the Doctor. == Conception and development ==
