Martha Jones

Martha Jones is a fictional character played by Freema Agyeman in the long-running British science fiction television series ''Doctor Who'' and its spin-off series, ''Torchwood''. The show's first female black companion, she is a companion of the Tenth Doctor in ''Doctor Who'', after Rose Tyler (Billie Piper) but before Donna Noble (Catherine Tate). According to the character's creator Russell T Davies in his non-fiction book ''Doctor Who: The Writer's Tale'', Martha was developed from the beginning with the intention of appearing for the whole of the 2007 series, and to later make guest appearances in subsequent series and crossover appearances in the show's two spin-offs; Martha subsequently made guest appearances in ''Torchwood'' series two and in ''Doctor Who'' series four in 2008 and special episode "The End of Time" in 2010. Martha was also intended to make guest appearances in the 2009 series of ''Torchwood'' and ''The Sarah Jane Adventures'', but could not due to the actress's other work commitments.

Within the series' narrative, Martha begins as a medical student who becomes the Doctor's time travelling companion after an incident at the hospital where she works. After well over a year (from the perspective of the Doctor and herself) travelling with the Doctor, Martha parts from the Doctor's company as she recognises how unhealthy their relationship has become. After returning to life on Earth, becoming engaged and finishing her medical degree, Martha finds a newfound level of independence when she is recruited into the paranormal military organisations UNIT, and briefly Torchwood. Having faced the end of the world single-handedly during her time with the Doctor, Martha is recognised for her skills both in the field and in medicine. Provided by Wikipedia
