"One-Winged Angel" is one of the most popular tracks of the Final Fantasy series. The song's name refers to Safer∙Sephiroth, who has six white wings where his legs should be and a grotesque black wing where his right arm should be, but since its original appearance, this title is commonly used to refer to Sephiroth himself and serves as a motif for the character (Sephiroth's original character theme from Final Fantasy VII is "Those Chosen by the Planet"). With Sephiroth's popularity, "One-Winged Angel" has received several arrangements and had several appearances outside Final Fantasy VII, never far from the presence of the villain it is associated with.
