Ok, but picture this. Mario and the gang walk up to the Peach's Castle. They're locked out. How is everyone gonna get in? Suddenly we see a beam of light come from off screen. It enters the Keyhole and we hear an unlocking sound. Mario and friends look over. Their jaws drop. The camera pans over and we see a familiar gloved hand holding the handle we all recognize. The camera pans outward and we see him fully standing there is all his glory. Sora is wielding the Kingdom Key. We then get his "Joins the battle screen" saying "Sora Unlocks The Battle." We then learn about his move set including using magic, we see his stage which could be a variant of Destiny Islands or the Keyblade Graveyard, we learn what songs they're adding from the series, and finally we see his Final Smash, which could be him in Final Form with every Keyblade being used.
