Fatality is a signature term from Mortal Kombat, the fighting game series first released in arcades in 1992, where players could finish a defeated opponent with a brutal special move. When the move landed, the game's announcer declared Fatality, and the word became inseparable from the franchise's over-the-top finishing style. As gameplay clips spread on YouTube, Twitch and TikTok, editors began lifting the short announcement for knockouts, fails and dramatic reveals outside the game itself, keeping it alive as a shorthand for a decisive, game-ending moment.
