>>50598211It's 2 different forms of the same pokemon at different points in time.
Koraidon what it was in the distant past, Miraidon is what it will be in the distant future, "Third" legendary is going to be its present self,
Story will involve bringing mir/koraidon into the present which will bring about dire consequences, then you have to find the third -aidon
Theme of the game will be to live in the now instead of wasting too much time reminiscing about the past or worrying about the future
The present -aidon you get will be able to form change into Mirai or Korai depending on the version you get
