Arceus.  The creator of the entire world.  He believed his world was perfect, and that nothing would ever go wrong.  However...a strange feeling overcame him, in which he noticed an anomaly.  A human born with a purpose greater than they knew, who was outcast by their own people and treated like the lowest when they were meant to be much higher.  A human meant to wield the powers of a god and hold a form halfway between human and mon, an "anthro" Pokemon form...that human being you.  It is time.
