Television Mickey Smith is first introduced in the series' 2005 reboot première episode, "
Rose". When Mickey's girlfriend Rose (
Billie Piper) begins investigating a mysterious alien called
the Doctor (
Christopher Eccleston), Mickey is captured by the alien
Nestene Consciousness, from which a living plastic facsimile of him (an 'auton') is created. Mickey, terrified by the revelation that alien life exists, fails to impress the Doctor, who only invites Rose to be his
travelling companion in time and space. In the year after Rose absconds with the Doctor, Mickey becomes the prime suspect for Rose's disappearance and becomes distressed as a result. However, he assists the pair in defeating the
Slitheen, a family of extraterrestrial criminals; using his
computer hacking skills, he commandeers a military
harpoon missile which he targets at
10 Downing Street to kill the Slitheen. Mickey then declines an invitation from the Doctor to join him and Rose in the
TARDIS. A much younger Mickey, played by Casey Dyer, appears briefly when Rose attempts to alter her childhood in "
Father's Day". In "
Boom Town", Mickey later meets up with the Doctor, Rose and new companion
Captain Jack (
John Barrowman) in
Cardiff, where he helps them foil a Slitheen plot. In the series' finale episode "
The Parting of the Ways", when Rose becomes stranded at home at the Powell Estate, Mickey uses a recovery truck to crack open the TARDIS's console, through which Rose is able to absorb the time vortex and save the universe from an invasion of the hateful mutant alien
Daleks. Having investigated a case of possible alien activity on Earth, Mickey alerts the Doctor and Rose to strange goings on at a school run by
Headmaster Lucas Finch (
Anthony Head) in "
School Reunion". On meeting the Doctor's former companions,
investigative journalist Sarah Jane Smith (
Elisabeth Sladen) and robot dog
K-9, Mickey begins to see himself negatively as the K-9 to Rose's Sarah Jane: "the tin dog". In the episode's conclusion, the Doctor finally takes Mickey aboard as his companion. He appears in the next three episodes "
The Girl in the Fireplace" and two-parter "
Rise of the Cybermen"/"
The Age of Steel", where the trio end up in a
parallel world where vicious, emotionless
Cybermen have just been invented. There, Mickey is mistaken for his parallel universe
doppelgänger "Ricky Smith", the leader of a human resistance group called the Preachers. In the story's conclusion, following Ricky's death, Mickey decides to stay behind in the parallel world to look after the parallel version of his grandmother (
Mona Hammond) and fight the Cybermen; Mickey's grandmother is dead in his universe. However, Mickey makes a surprise reappearance in finale episodes "
Army of Ghosts" and "
Doomsday", wherein like the Cybermen, he and fellow Preacher
Jake Simmonds (
Andrew Hayden-Smith) are able to cross the Void into our world. There, they help the Doctor repel simultaneous Dalek and Cybermen invasions. In the episode's conclusion Mickey returns to the parallel world, this time with Rose who is now also trapped there. Mickey returns again in the
series four finale episode "
Journey's End" (2008), along with Jackie. Alongside many other recurring characters, they have come to help the Doctor defeat
Davros (
Julian Bleach), the creator of the Daleks. Mickey and Jackie save Sarah Jane from a Dalek attack, and the trio then surrenders to other Daleks in order to be taken to the Dalek headquarters, the spaceship
Crucible. There they join forces with Captain Jack. After
Donna (
Catherine Tate) defeats Davros, Mickey is one of several former companions who pilot the TARDIS. In the episode's conclusion, Mickey declines to return to the parallel universe because, having both broken up with Rose and his "parallel" grandmother having been dead, he can find no reason to go back - in fact, he tells the Doctor, "I'm not stupid, I can work out what happens next," obviously realizing that Rose will wind up with the metacrisis Doctor. Leaving the TARDIS, he follows after Jack and the Doctor's former companion,
UNIT officer
Martha Jones (
Freema Agyeman). Mickey next makes a brief final appearance in the Tenth Doctor's final episode "
The End of Time" (2010), when the dying Tenth Doctor visits all his companions and saves the now-married Mickey and Martha, "freelance alien hunters", from a
Sontaran sniper.
Online media Mickey appeared extensively in
electronic literature and tie-in videos hosted by the BBC website. These websites are "in-universe", part of an
alternate reality game set within the show. Concurrent with the 2005 series, Mickey ran the
conspiracy theorist website "Who is Doctor Who?" (first featured in "Rose"). In the 2006 series, however, the website became "Defending the Earth". Both featured videos of Clarke as Mickey, informing the viewer of facts about the series, or introducing "missions" which would be played out in online
Macromedia/Adobe Flash games. Several of Mickey's
blog entries tied into the overarching Torchwood story arc, depicting interceptions by the Torchwood Institute. Games include tie-ins to the plots of 2006 series episodes, such as "
Tooth and Claw" and "
Fear Her". Clarke also starred as Mickey Smith and Ricky Smith in several online '
Tardisodes'; these were 60-second
webisodes and
mobisodes (available online and via mobile phone download), which only aired in 2006. For the "School Reunion" TARDISODE, Mickey is researching UFO sightings online when he is blocked by a notice referring to Torchwood, prompting him to call Rose to investigate. In the TARDISODE prequel to "Rise of the Cybermen", Ricky Smith is seen viewing a message sent to all the Preachers, again on his laptop.
Literature Mickey appears in one
New Series Adventures novel alongside the Doctor and Rose,
Winner Takes All (2005), and two Tenth Doctor novels,
The Stone Rose and
The Feast of the Drowned. These novels are set before Mickey joins the Doctor and Rose as traveling companion in the episode "School Reunion". Mickey features as the centric character in the
short story "Taking Mickey" from the
Doctor Who Files series of hardbacks from
BBC Children's Books. In
Gareth Roberts'
Doctor Who Magazine comic book story "The Lodger", the Tenth Doctor is forced to cohabit with Mickey; this story was later adapted into an
Eleventh Doctor (
Matt Smith)
episode of the same name, with Mickey's role supplanted by that of Craig Owens (
James Corden). In the comic book story "The Green-Eyed Monster", Rose becomes jealous when Mickey appears to suddenly have several
Amazonian girlfriends. It is later revealed that these were actors hired by the Doctor in his bid to defeat a creature that feeds on jealousy which had possessed Rose. In the ongoing Ninth Doctor comic series, an unconventional storyline sees Mickey Smith, from a time after he has witnessed the Tenth Doctor depart for his regeneration, forced to deal with mysterious events in San Francisco with the aid of the Ninth Doctor. During this storyline, Mickey takes care to prevent himself being seen by Rose or the Ninth Doctor witnessing his wife Martha, with it being implied that this sight of what Mickey would become influenced the Tenth Doctor's higher opinion of Mickey after his regeneration. ==Development==
