Okay, so far all we know about KH2 is that it is one year after KH. There are also new enemies called the Nobodies or something like that. Ansem is definetely back. There is a Blonde haired Kid (BHK) that can weild both the Oathkeeper and Oblivion, how he got them we don't know, yet. There are 5 unknowns. One is Ansem and some think that another is Riku. If you saw Another Side Another Story (ASAS) it shows Riku, the bilndfolded one, wearing a trenchcoat similar to the Unknowns. King Mickey is back. So are the heartless. The comfirmed towns so far are Halloween Town, The Colloseum, Hollow Bastion and a town similar to Traverse town called Twilight Town. Auron, Hercules, Meg, Donald, Goofy, Sora, Kairi, Riku, Ansem and , if you played KH Final Mix so is the Enigmatic Man. If I missed anything please reply and tell me cuz i need to know.
