Sara Kingdom is a fictional character played by Jean Marsh in the
long-running British science fiction television series Doctor Who. A
security officer for Mavic Chen from the 40th century, she later
joined the First Doctor and Steven to work against Chen's interests.
She is sometimes classed as a companion of the First Doctor but the
BBC's official Doctor Who website does not include her in their list
of companions. Her status as a companion is commented upon in its
Episode Guide.Sara appeared in parts four to twelve of the twelve-part
1965 serial The Daleks' Master Plan. Only two episodes in which she
appears still exist in the BBC archives. Her character took on
elements of the companion role to replace the character of Katarina,
who was killed off earlier in the same story.Sara is a Space Security
Agent, the sister of Bret Vyon, another agent who is aiding the Doctor
in trying to defeat the Daleks. There is an implication that she was
born on Mars Colony 16, where her brother had been "bred". Told that
Vyon is a traitor by Mavic Chen, the Guardian of the Solar System (who
was in league with the Daleks) and ordered to kill whoever is working
with him, she shoots her brother and is about to do the same to the
Doctor and Steven when they are transported across space to the planet
Mira. There she learns, to her horror and grief, that her
unquestioning obedience has not only led her to unjustly kill her
brother, but also that by doing so she has prevented Vyon from warning
Earth of the Dalek plot. She then joins the Doctor in his fight,
briefly travelling in the TARDIS to several different locations in
space and time as the Doctor and Steven try to return the ship to
Kembel for a final confrontation with Mavic Chen and the Daleks.When
the Doctor activates the Time Destructorâ€"a device that accelerates
timeâ€"as part of his plan to stop the Daleks, he orders his
companions back to the TARDIS for their protection. However, Sara
follows him, not knowing the nature of his plan but concerned it might
fail. As a result, she and the Doctor are both caught in the field of
the Time Destructor as it rapidly ages everything around it. While the
Doctor, being a Time Lord, can withstand the worst of the
effectsâ€"merely becoming an even older manâ€"Sara, being human,
cannot. As Steven watches helplessly, Sara ages (being portrayed as an
old woman by May Warden) and dies, her remains aging to dust. Steven
attempts to rescue his friends; he, too, is briefly affected and ages,
before he reverses the Time Destructor. This rejuvenates himself and
the Doctor back to their previous ages, but does not save Sara. Sara Kingdom Biography, NetWorth, Height, Age, Weight, Family, Married, Son, Daughter
