Final Mix question must get the first post. I will answer.
Sora: Who are you?
Xemnas (Unknown): Ah it seems you are special too
Goofy: Ansem?
Xemnas (Unknown): Thats a familiar sound. You look like him.
Sora: Whats that supposed to mean?
Xemnas (Unknown): Which means, you are not complete.
Xemnas (Unknown): Incomplete One.
Xemnas (Unknown): That Power.
Xemnas (Unknown): Allow me to test your power.
(battle)
Xemnas (Unknown): Truly fascinating. This is going to be enjoyable.
Sora: What are you talking about?
Xemnas (Unknown): In your present state, you most likely will not understand. Nevertheless, the time when we will meet again will doubtless come.
Sora: Wait! Who are you?!
Xemnas (Unknown): I am...
Xemnas (Unknown): A mere shell.
Before the battle, the princesses of heart speak of Xemnas' presence.
Cinderella: I wonder, could that gates appearance be a sign of something bad?
Aurora: From that gate that suddenly appeared, I can sense the power of darkness... No not darkness, Something different.
Snow White: Perhaps it's more dangerous than the darkness.
Jasmine: If it were the power of darkness, we would be able to hold it back a little. But, this is different. A power other than darkness. Light, Darkness and a third power?
Alice: What on earth is that?! A different feeling from darkness... Sora, take care!
