Lord Voldemort is the main antagonist of the Harry Potter books and films, the dark wizard whose name other characters fear to speak. Online, short clips of his voice are reused far beyond fan edits, because a formal introduction from such a feared character creates instant irony when applied to ordinary people, pets and game avatars. The sound has become a staple of villain reveal memes, where the contrast between the serious delivery and the harmless subject is the joke, and it remains recognisable even without any visual context.
