What if this is how KH3 ended? They finally defeat Xehanort and then suddenly when they go up to Kingdom Hearts, Oswald appears holding the X-Blade. And then he says to Mickey that he has used time travel to create Kingdom Hearts in the past and created light and darkness over his jealousy of Mickey stealing his spotlight from back in the thirties. Then Oswald becomes the final boss and since he is the creator of Kingdom Hearts and all keyblades he is practically badass and nearly unbeatable.
