Scariest FF moment

I'm probably going to get some raised eyebrows at this, but my scariest moment in FF history was probably a scene in FF13. As a whole, I dislike 13. But one scene in particular really tugged at me.

When the party confronts Dysley, and he turned out to be a Fal'Cie called Barthandelus. It was a pretty big twist, for me. I didn't see it coming. The music that started playing, and the look of fear on the party's face... the hopelessness they seemed to feel. It really got me.
