I love Kingdom Hearts

I'll bet you a million bucks it is. Vanitas wasn't in any part of this game, and yet he was such a huge antagonist in BBS. There's NO WAY he's not in this game, and I guarantee you they wanted to keep him mysterious, and it all pretty much connects. I mean, which other important character in the series has red eyes? And they wouldn't put some random nightmare under that hood, it's gotta be a significant character. It HAS to be Vanitas. EDIT: And it can't be a brand new character because it is far too late in the series.

The red-eyed unknown is Vanitas. When the newborn heart of Sora's came in contact with Ventus's fractured heart, he also directly contacted Vanitas's heart. After feeling a sharp pain in his chest, Vanitas's body fell to the ground of the wasteland near the Keyblade Graveyard and almost lost his consciousness, feeling being engulfed by absolute Darkness. That was when Vanitas heard Sora's voice and then he saw Light. The Light eventually surrounded his whole body. He then heard a voice saying, "Let's open the door". Vanitas then opened his eyes and found out that now he had a normal boy's face. And basically the other person who connected with Ventus's heart, Vanitas would look like that person. And that's why he looked like Sora in BBS. Before Ven's heart came in contact with Sora's, Vanitas's original form was merely a faceless being, much like a heartless, but with red eyes.

Okay I'm slightly confused. So does Sora just get up and walk away like nothing happened and leaves Riku and everyone else behind? Because that would be pretty damn weird. Or did he wake up in the RoD? Because that would be very interesting.
