Dalek
The Daleks 
i are a fictional extraterrestrial race of mutants principally portrayed in the British science fiction television programme Doctor Who. The Daleks were conceived by science-fiction writer Terry Nation and first appeared in the 1963 Doctor Who serial The Daleks, in the shells designed by Raymond Cusick.
Drawing inspirations from the real-life example of the Nazis, the Daleks are merciless and pitiless cyborg aliens bent on conquest of the universe and the extermination of what they see as inferior races; their catchphrase, "Exterminate!", is a well-recognised reference in British popular culture. Within the programme's narrative, the Daleks were engineered by the scientist Davros during the final years of a thousand-year war between his people, the Kaleds, and their enemies the Thals. With some Kaleds already badly mutated and damaged by nuclear war, Davros genetically modified the Kaleds and integrated them with a tank-like, robotic shell, removing their every emotion apart from hate. His creations soon came to view themselves as the supreme race in the universe, intent on purging the universe of all non-Dalek life. Collectively they are the greatest enemies of Doctor Who's protagonist, the Time Lord known as The Doctor. Later in the programme's history, the Daleks acquired time travel technology and engaged the Time Lords in a brutal Time War affecting most of the universe, with battles taking place across all of history. They are among the show's most popular villains and their various returns to the series over the years have typically been widely reported in the television press.
