The theme grew out of the Mortal Kombat fighting-game franchise, which began in arcades in the early 1990s, and it reached a much wider audience through the 1995 Mortal Kombat film, where its driving electronic sound became the series signature. Since then it has been reused in trailers, game promotions, sports arenas and countless online edits, because listeners recognise it instantly as a signal for a contest. Its longevity comes from that simple association: the music alone can turn an ordinary entrance into a showdown.
