One thing that has always bugged me about Sora is that the time he is a heartless has very little influence on his overall character. The only time they bring it up is when they are refering to Roxas. You would think that being a being of darkness would have a profound effect on ones emotions and heart. While you could argue that CoM had Sora as a slightly darker character, I'm more inclined to think Namine messing around in his head would have caused the change, and besides the development that Sora got in CoM is almost a moot point since he forgot it all. However, there was one manifestation that the darkness seemed to take in KH2, Anti-Form. Because Drive Forms are, at least partially, cannon, Anti-Form should be as well. I find it interesting that the manifestation of Sora's darkness started to appear a year after he became a heartless and not immediatly, especially when you consider that his body (and possibly Ven's heart) was running around completly separate from him as Roxas. The only explanation I can think of is that Kairi's shell of light that Sora used may have at least somewhat suppressed that darkness. Now that Sora no longer has that shell, it makes more sense (at least to me) of Anti-Form's existance. This could be extremely important for KH3D. We know that KH3D deals with Sora's data. Theoretically, the darkness could find that data to manifest itself as different people from past games, so yea it basically means that all of the apearences of previous characters (outside of the pre-rendered opening parts and Lea, Ienzo, and Aeolus since I believe that's outside of the RoS) are illusions brought on by Sora's (and possibly Riku's) individual darkness and the data. It does explain how Vanitas poped out of seemingly nowhere at the end of the trailer. I believe that the relationship between the light and the darkness in the RoS might be like the relationship between Nightmares and Spirits. They exist to oppose each other yet are still two parts of the same whole. This may mean that the indiviual light may use the data to manifest itself as other characters as well. I think it would be intersting if we could see how they deal with it differently. Sora's never had to deal with it much and Riku probably thinks the problems been mostly solved
