The Tenth Doctor is an incarnation of the Doctor, the protagonist of
the BBC science fiction television programme Doctor Who. He is played
by David Tennant in three series as well as nine specials. As with
previous incarnations of the Doctor, the character has also appeared
in other Doctor Who spin-offs.Within the series' narrative, the Doctor
is a centuries-old alien Time Lord from the planet Gallifrey who
travels in time and space in the TARDIS, frequently with companions.
At the end of life, the Doctor regenerates; as a result, the physical
appearance and personality of the Doctor changes. Tennant's portrayal
of the Doctor is of an outwardly charismatic and charming adventurer
whose likable and easygoing attitude can quickly turn to righteous
fury when provoked.This incarnation's companions include working class
shop assistant Rose Tyler (Billie Piper), medical student Martha Jones
(Freema Agyeman), and fiery temp worker Donna Noble (Catherine Tate).
He eventually parts ways with them all by the end of the 2008 series
finale, "Journey's End", after which he attempts to travel alone for
the duration of the 2008â€"2010 specials before being accompanied by
Donna's grandfather Wilfred Mott (Bernard Cribbins) on his final
adventure in "The End of Time". Tenth Doctor Biography, NetWorth, Height, Age, Weight, Family, Married, Son, Daughter
