Is it ever established why there are inconsistencies between this game and other kingdom hearts games? The example I'm thinking of is Hercules being a buff hero while in birth by sleep hes a teenager. Birth by sleep takes place after the keyblade war. I know the purpose of union X is to teach us a bit about the foretellers, so are the disney worlds in union x just not considered canon? At the beginning of the game, Chirthy explains to us that the medals we use are from the future (Sora, Riku, Roxas etc.) So I'm wondering if there is some kind of explanation that was also said involving the worlds. Thanks in advance.
