Personally, my favorite moment was the first time we got to see Kain without his helmet on at the end of Final Fantasy 4 (Spoiler?).
Throughout the game I always imagined him as a cold hearted beast, with an iron will, and a personality befitting of a hardened veteran of battle... then we get to see him on the mountain top, with his helmet off, and his hair blowing in the wind. It kind of reminded me that he was human. I would've personally loved to have a backstory on Kain's life beyond that which was shown in Final Fantasy 4, (Which was essentially no backstory at all.)
