The line comes from Mortal Kombat: Shaolin Monks, the 2005 action adventure spin-off in which Scorpion appears as one of the series' most recognisable undead ninjas. Fans clipped his threatening dialogue for soundboards and gaming videos, where it quickly became shorthand for an ominous warning before a fight. It endures because Scorpion remains a defining Mortal Kombat figure, and the short, menacing delivery works just as well in modern edits as it did in the original game.
