I'm wondering, what if Arceus is the villain but it is because he sees what Cyrus will or will try to do in the future? Remember, there is a timeline in the games where the villains win, or are on the verge of winning before being taken by Team Rainbow Rocket and joining them. What if Arceus is trying to hinder the player because the information gathered by the player is later used by Cyrus to nearly bring about the end of the universe?
