The Daleks are an extraterrestrial race of mutants from the British science fiction television series Doctor Who. Within the series narrative, Daleks are cyborgs made from their original forms, extraterrestrial Kaleds from the planet Skaro, genetically modified and integrated within a tank-like robotic mechanical shell. They were created by the scientist Davros during the final years of a thousand-year war against the Thals. The Daleks are a powerful race bent on universal conquest and domination, utterly without pity, compassion or remorse. Various storylines portray them as having had every emotion removed except hate, leaving them with a desire to purge the Universe of all non-Dalek life.
