Ive been watching some of the Pokemon movies mainly the first one and I noticed that the story of Mewtwo in Red and Blue VS. the first movie is somewhat different and the games are much more darker. I also noticed that in Movie 14 they had all this dragon aura stuff that is never mentioned in the game at all and the story behind Kyurem and Resh/Rom is completely different. Same goes for Deoxys. I was wondering if maybe the anime and the games take place in different universes with different backstorys or Nintedo just markets the anime towards kids with no dark tales like in the game.
