The Daleks were introduced in Doctor Who in 1963, created by writer Terry Nation, and quickly became the Doctor's most famous enemies. Their grating electronic voices and single-minded catchphrase around extermination turned them into a lasting piece of British science fiction. Clips of Dalek lines have circulated for years in fan edits, parodies and soundboards, detached from full episodes. This shorter threat works as a standalone reaction because the voice alone signals the character, allowing creators to reference decades of television history in just a couple of seconds.
