The line comes from Sisyphus Prime, an optional Prime Sanctum boss in the fast-paced shooter ULTRAKILL. He delivers “Destroy!” as one of his combat callouts, so players associate it with a sudden, punishing attack. Clips of the boss’s emphatic dialogue spread through gameplay videos, fan edits, animations, and memes centered on the game’s difficult encounters. The quote remains recognizable because it is extremely short, clearly delivered, and easy to synchronize with an impact, abrupt cut, or moment when someone is about to be overwhelmed.
