I don't suppose that every set of time in the KH universe would have different enemies, depending on the Keyblade users/jerks who try to destroy stuff. After all, if all of the enemies from way back when don't appear anymore, and that the enemies of today didn't exist back then, the only possible conclusion is that Jesus did it.
