Doctor Who is a British science fiction television series broadcast by the BBC since 1963. The series depicts the adventures of a Time Lord called the Doctor, an extraterrestrial being who appears to be human.

The Doctor explores the universe in a time travelling space ship called the Tardis. The Tardis exterior appears as a blue British police box, which was a common sight in Britain in 1963 when the series first aired.

With various companions, the Doctor combats enemies, works to save civilisations, and helps people in need.
