<P> His costume was unveiled on July 27, 2005 . He generally wears either a dark brown (with blue pinstripes) or a blue (with rust red pinstripes) four - buttoned suit, a shirt and a tie, a light brown faux - suede overcoat (which he claims was given to him by Janis Joplin), and different coloured pairs of Converse All - Star sneakers, depending on his suit . According to an interview on Parkinson, David Tennant and Russell T Davies got the idea for the Tenth Doctor's costume from an outfit Jamie Oliver had worn on Parkinson just after Tennant had taken the role . David Tennant has commented that he would vary the combination of the buttons he fastened on his jacket in different episodes . Tennant thought the look was very geek chic . </P> <P> The Doctor dons a pair of dark tortoise - shell rectangular frame glasses, an affectation (along with his signature footwear) borrowed from the Fifth Doctor . He also occasionally sports a pair of Red - Cyan 3D glasses, both as a joke and for practical reasons . The Tenth Doctor's costume became so popular that it has spawned numerous recreations (including a BBC - licensed replica of the Tenth Doctor's overcoat by AbbyShot Clothiers and a white / red version worn by Tennant when he co-hosted Comic Relief), and has been cited by costume designer Louise Page as the costume she is most proud of from her time on Doctor Who . </P> <P> The Ninth Doctor (Christopher Eccleston) regenerates into the Tenth Doctor (David Tennant) at the climax of the 2005 series finale, "The Parting of the Ways"; he re-introduces himself to his companion Rose Tyler (Billie Piper) in an untitled Children in Need mini-episode . In the Christmas special, he is in a comatose state for most of the episode, following his regeneration . After eventually waking up, he defeats the alien Sycorax and saves Earth; in the process, he loses a hand, which regrows owing to his recent regeneration . Amongst other 2006 series adventures, the Doctor and Rose save Queen Victoria (Pauline Collins) from a werewolf, resulting in the creation of the anti-alien Torchwood Institute . The Doctor shares an adventure with two former companions, journalist Sarah Jane Smith (Elisabeth Sladen) and robot dog K - 9 (John Leeson), before taking on Rose's boyfriend Mickey (Noel Clarke) as a second companion . The TARDIS slips through a crack in the Time Vortex causing them to be stranded on a parallel Earth, where they encounter the Cybermen . After saving parallel Earth, Mickey decides to stay and help stop the Cybermen around the world despite the Doctor telling him he can never return . He and Rose become stranded on a planet orbiting around a black hole where The Beast is waiting, with a Torchwood team . While there The Beast taunts the Doctor and Rose about Rose's death . During the 2012 Olympic Games, the Doctor picks up the Olympic flame and carries it to the end, starting the Games . The series finale takes place in contemporary London, where modern - day Torchwood is the scene for war between the evil alien Daleks and parallel - universe cyborgs the Cybermen; saving the Earth costs the Doctor Rose, who is stranded in a parallel universe, along with Mickey and her mother, in "Doomsday". </P> <P> In the closing scene of "Doomsday", a mysterious bride (Catherine Tate) inexplicably appears in his TARDIS . The 2006 Christmas special sees the Doctor and bride - to - be Donna Noble save the Earth; Donna saves the Doctor from going too far in his revenge against the alien Racnoss and declines his offer of companionship . In the 2007 series, the Doctor takes on Martha Jones (Freema Agyeman) as his new companion . Together, they witness the mysterious Face of Boe (Struan Rodger) prophesy to the Doctor that "you are not alone ." They are rejoined by former companion Captain Jack Harkness (John Barrowman) in a three - episode adventure where presumed - deceased archenemy and fellow Time Lord the Master (John Simm) becomes Prime Minister of the United Kingdom and enslaves the Doctor for one year . Martha's plan sees the Doctor infused with the world's psychic energies, and he easily defeats the Master, who seemingly refuses to regenerate and dies in the Doctor's arms . Following this adventure, in the dénouement of series finale "Last of the Time Lords", Jack and Martha both depart the TARDIS, and the Doctor is shocked to see what appears to be the RMS Titanic crash into it . Set moments prior, another Children in Need mini-episode, "Time Crash", features a brief encounter between Tennant's Tenth Doctor and the Fifth Doctor (Peter Davison), containing meta - humour surrounding the fact David Tennant had watched and loved Davison's doctor as a child . In parallel with the third series, Tennant lends his voice to the animated serial The Infinite Quest . </P>
