The line comes from Mortal Kombat, the fighting game series that began in arcades in 1992, where Shang Tsung is a powerful sorcerer who steals the souls of defeated fighters. 'Your soul is mine' became one of his defining threats, repeated across later games, films and trailers as a shorthand for total defeat. As clips spread on soundboards, TikTok and YouTube edits, the clean version became popular because it is short, instantly recognisable and easy to drop over gameplay. It remains a favourite for gaming memes and villain edits today.
