Daleks

The Daleks are a fictional extraterrestrial race of mutants principally portrayed in the British science fiction television programme Doctor Who. They were conceived by science-fiction writer Terry Nation and first appeared in the 1963 Doctor Who serial The Daleks, in shells designed by Raymond Cusick. Drawing inspiration from the Nazis, Nation portrayed the Daleks as violent, merciless and pitiless cyborg aliens who demand total conformity to their will and are bent on the conquest of the universe and the extermination of what they see as inferior races. Collectively, they are the greatest enemies of Doctor Who's protagonist, the Time Lord known as "the Doctor." During the second year of the original Doctor Who programme, the Daleks developed their own form of time travel.
