Tenth Doctor <=SEP=> The Tenth Doctor is an incarnation of the Doctor , the protagonist of the BBC science fiction television programme Doctor Who , who 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 . In the programme 's narrative , the Doctor is a centuries-old Time Lord alien from the planet Gallifrey who travels in time in his TARDIS , frequently with companions . When the Doctor is critically injured beyond medical repair , he can regenerate his body ; in doing so , his physical appearance and personality change , and a new actor assumes the role . 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 2008 -- 2010 specials before being accompanied by Donna Noble 's grandfather Wilfred Mott on his final adventure in The End of Time .   In November 2013 , Tennant 's Doctor was voted `` The UK 's favourite Doctor '' in a survey held by the Radio Times magazine .

Donna Noble <=SEP=> Donna Noble is a fictional character in the long-running British science fiction television series Doctor Who . Portrayed by British actress and comedian Catherine Tate , she is a companion of the Tenth Doctor ( David Tennant ) . Originally appearing in the closing scene of the show 's 2006 series and as a special guest star in its following Christmas special , `` The Runaway Bride '' , Tate was not expected to reprise her role as Donna ; for series 3 ( 2007 ) , the Doctor travelled alongside medical student Martha Jones ( Freema Agyeman ) . However , Tate expressed interest in returning to the role , and she returned as Donna for the duration of the series 4 ( 2008 ) , and in a subsequent 2009-10 Christmas and New Year 's special .   Within the series ' narrative , Donna begins as an outspoken Londoner in her mid-30s , a temp worker from Chiswick whose view of the universe is small in scope . Although she at first finds alien time traveller the Doctor terrifying , their initial encounter leaves her unsatisfied with her normal life and she decides to travel alongside him when the next opportunity arises . Donna becomes an asset to the Doctor on his adventures and it is she who ultimately saves the universe in the series 4 finale , although tragically at the cost of the memories of her travels with the Doctor . In a contrast to the Tenth Doctor 's prior companions , who both harboured romantic feelings for him , Donna and the Doctor shared a strictly friendly relationship ; and she did not feel the need to prove herself to be allowed to travel with the Doctor , who refers to her as his `` best mate '' .
