Doctor Who is a science fiction series from 1963. It follows The Doctor, a Time Lord from the planet Gallifrey, on his journeys through time and space in his TARDIS (Time And Relative Dimensions In Space) a spaceship that looks like a blue police phonebox (it only looks like that because the “chameleon circuit” is broken, it would normally be able to look like practically anything). He normally has a companion, most often a female, whom he shows the wonders in space and time. The show had a pause, but restarted in 2005 with Christoffer Eccleston as the Doctor (he has now been replaced by David Tennant, the current and 10th Doctor) and Billie Piper as his companion, the human Rose Tyler (she left the show in 2006).

The Doctor himself: The Doctor is, as mentioned earlier, a Time Lord from the planet Gallifrey. Sadly, he had to destroy his home planet, and with it all of his own race friends as well as family, during a great Time War (the last of these), because this was the only way to save the universe from the greatest enemy of the universe, The Daleks. A cold hearted race of robot like creatures, they have no feelings except hatred and live for the goal to rid the universe from anything that isn’t “of Dalek design”. So now the 900 year old Doctor wanders the universe and on more than one occasion saves the Earth along with other planets.
