24Chaos - Final Fantasy
Chaos is at the center of a dubious plan to create an endless cycle of evil and destruction. Four Fiends send the knight Garland back in time, who in turn sends the Fiends into the future in order for them to put Garland in the past first.
It's a little confusing
and does not make a whole lot of sense, but it is a scheme the Warriors of Light must thwart none the less. Garland reveals himself to be Chaos, and the party dukes it out with him, ultimately winning and correcting the timeline.
