kyurem hidden moves possibly will be used as a movie event, or for the third game.(like victini)
if a new forme/the original one happens to appear in the third game, what should be is type be? in games and anime dragon type is pure power so should the original be pure dragon?
or maybe kyurem isn't the remains of the original one but a new being to balance/oppose the other two, something like palkia dialga and giratina
just brainstorming my mind until the games come out
