The Daleks are a fictional extraterrestrial race from the British science fiction television series Doctor Who. Created by writer Terry Nation in 1963, they are known for their robotic appearance, characterized by a dome-shaped head, eyestalk, and a plunger-like arm. The Daleks are infamous for their catchphrase, "Exterminate!" and their relentless pursuit of conquest and domination. Originating from the planet Skaro, the Daleks were created by the scientist Davros as a means to ensure the survival of their race. They are driven by a deep-seated hatred for all non-Dalek life forms, which leads them to seek extermination of their enemies. Their advanced technology and ruthless tactics make them one of the most iconic villains in science fiction.
