Page "Mickey Smith" Paragraph 2

Mickey Smith is first introduced in the series ' 2005 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 since Rose absconded with the Doctor, Mickey has been the prime suspect for Rose's disappearances and has become 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.

After the Doctor regenerates, Mickey helps Rose and her mother Jackie ( Camille Coduri ) attend to the unwell new Doctor ( David Tennant ).
