Sephiroth is the central antagonist of Final Fantasy VII, first released in 1997, and his battle theme, One-Winged Angel, became one of the most recognisable pieces of video game music ever written. Its Latin choir and dramatic orchestral arrangement were unusual for the time and helped turn a boss fight into a cultural moment. The theme has since returned in remakes, concerts and countless fan edits, which is why short clips of it still work instantly as shorthand for an unstoppable, theatrical villain.
