Captain Jack Harkness, Torchwood's team leader.  Jack is an ex-Time Agent who unsuccessfully tried to con The Doctor & Rose.  After joining The Doctor in his adventures Jack changed from conman to hero.  He went on to transform Torchwood as a tribute to the Doctor.  Captain Jack, though is not his real identity and his origins are obscure, just the way he wants it.  However, he has vast practical experience of working with aliens and dealing with crisis situations.  He has come through a lot of scrapes, always emerging intact thanks to 'Bad Wolf' Rose Tyler and this has made him fearless in the presence of danger.  In fact, he's usually ready with a flirtatious quip whatever the threat.  And could he be the Face of Boe?

 

Gwen Cooper, a former police officer, brings procedural skills to the team and she is recognised as Torchwood's second in command.  Gwen possesses a sensitivity that helps the team greatly in dealing with victims.  She is grounded, straightforward and very determined, and in the shadowy world in which Torchwood operates she often acts as the team's conscience.

 

Doctor Owen Harper trained as a medical doctor, but this expertise has grown massively since joining Torchwood.  As well as attending to the team's emergency medical needs and working on the human victims of alien activity, he has gained invaluable expertise in alien anatomy.  A very self confident individual, many would say too  over-confident for his own good sometimes, his commitment to Torchwood has never been doubted.

Toshiko Sato, Torchwood's technical expert, is quiet but highly intelligent. Her role is to assess the potential application of alien technology for humanity's use.  Toshiko also has a great knowledge and understanding of practical physics, which makes her useful as a field agent.  She is focused and intensely professional individual, though very sensitive.

 

Ianto Jones is Torchwood's administrator.  His knowledge is eclectic  and his attention to detail second to none with an uncanny ability to anticipate the team's needs before they have arisen.  Although he dislikes it when this remarkable efficiency is taken for granted, Ianto is however more than capable of undertaking field work for Torchwood.
