Round 1 is the opening announcement in Mortal Kombat, the long-running fighting game series that began in arcades in 1992. In each match, the announcer calls the round before the fighters clash, a format that has remained a recognisable part of the series across its many sequels. Clips of the call have spread through gameplay videos, streams and short edits, where creators reuse it as a shorthand for a contest beginning. It remains popular because the voice and phrasing instantly frame almost any showdown, whether serious or played for laughs.
