Darth Plagueis is a Sith Lord from Star Wars lore, first named in Revenge of the Sith in 2005 when Palpatine tells Anakin the story of a master who could cheat death. The tale became one of the saga's most quoted scenes, spawning countless memes, edits, and references long after the film's release. Fans reuse the name as shorthand for forbidden knowledge, hidden power, and ironic tragedy, which keeps the short clip useful far beyond its original scene.
