Wonder Woman is a DC Comics superhero created by William Moulton Marston, first appearing in 1941, and her music has become shorthand for female strength and heroism on screen. The modern cinematic version, with its driving electric cello and pounding drums, was introduced for her film debut in Batman v Superman: Dawn of Justice in 2016 and carried into Wonder Woman in 2017. Since then, the motif has spread far beyond the films, appearing in trailers, sports broadcasts, workout videos and social edits whenever a moment needs instant heroic energy.
