Savior (Lightning Returns)

Savior is a term encountered in Lightning Returns: Final Fantasy XIII. It is the name given to a female warrior chosen by Bhunivelze to usher in the new world. According to a prophesy stored in the Oracle Drive, the Savior is a harbinger of doom who will attempt to destroy the world, and that a hero will rise up and prevent her from performing her task.

Lightning is the current Savior, and consequently Noel is determined to fight and defeat her, believing himself to be the 'hero' of the prophesy. There have apparently been several Saviors, but Lightning, according to Lumina, is different from the others.
