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 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. In the beginning of the second Doctor Who TV series that debuted in 2005, it was established that the Daleks had engaged in a Time War against the Time Lords that affected much of the universe and altered parts of history.
