Flawless Victory comes from Mortal Kombat, the fighting game series that debuted in arcades in 1992. The announcer calls it when a player wins a round without losing any health, alongside other famous calls like Finish Him and Fatality. As the series moved to home consoles and tournaments, the line became one of its most quoted phrases. Clips and edits online later detached it from matches entirely, using it for any clean, one sided win in games, sports and everyday challenges, which keeps the decades old call instantly recognisable.
