Wonder Woman first appeared in DC Comics in 1941, but this modern sound comes from her film appearances, debuting in Batman v Superman: Dawn of Justice in 2016. Composed by Hans Zimmer and Junkie XL, the electric cello theme returned in the 2017 Wonder Woman film starring Gal Gadot and became linked to the character. Online, the riff spread across edits, trailers and social videos as shorthand for a powerful entrance, and it remains widely used whenever a reveal needs instant superhero weight.
