One-Winged Angel originated as Sephiroth's battle theme in Square's 1997 game Final Fantasy VII, with music composed by Nobuo Uematsu. Its choral style and intense arrangement made it one of the most recognized tracks in game music, and later versions appeared in remakes, concerts and crossover games. Online, short excerpts spread through meme edits and boss-introduction jokes because the song instantly communicates final-battle stakes. It still gets used whenever creators want a reveal to feel bigger, darker and theatrically overpowered.
