Galaxy 4 is the first serial of the third season of the British science fiction television series Doctor Who. Written by William Emms and directed by Derek Martinus, the serial was broadcast on BBC1 in four weekly parts from 11 September to 2 October 1965. In the serial, the First Doctor and his travelling companions Vicki and Steven arrive on an arid planet, where they encounter the beautiful but dangerous Drahvins and the hideous but friendly Rills, two crash-landed species in conflict with one another. Both species wish to escape as the planet is set to explode in two dawns, but the Drahvin leader Maaga wants only her people to make it out alive.
The Drahvins are depicted as beautiful but ultimately cruel, in contrast to the unattractive but friendly Rills. They were originally male, but rewritten as female due to the emerging women's liberation movement.
