Please list all the theories that you believed about a specific KH game BEFORE it was released.
KH2:
I believed that the nobodies were white heartless and were the non existant counterpart mention in the secret ansem reports in Final Mix. I also believed that they were the true puppet masters of Ansem SOD. I also (correctly) thought that the blonde kid(Roxas) was Sora's non existant counterpart, that the red haired guy(Axel) was Riku's non-existant, that the red-skinned man(DIZ) was Ansem's non-existant and that Kairi was Ansem's daughter(because she was a princess and Ansem was the king of Hollow Bastion).
KH 358/2 days:
I believed that the game would show Roxas's birth and that Xion was Aqua's nobody
KH BBS:
I believed MX's apprentice was named Chasers and that Ven was Sora's father, Aqua was Riku's mother. Both Ven, Aqua, and Chasers died in the final battle while Terra, Master Xehanort, and Eraqus clashed and there was no victor. Ansem the wise later finds them later haveing lost their memories, except for Terra who remembers the name Xehanort, and takes them in. Later Xehanort discovers that he's really Terra but Braig and Dilan don't remember who they are. That's right I believed the theory that Xigbar was MX and Xaldin was Eraqus.
For Coded and DDD I didn't really care about those games until they came out to come up with any theories about them.
