The world you know is gone. Unknown to the masses, both human and Pokémon. Mewtwo, fed up with humanity never seeming to change, and Arceus, sick of humans seeing themselves as superior, combined their powers and tilted the scales. The technology that humans used to trap and contain Pokémon cease function. Every Pokémon in a Pokéball or Box was released and all Pokémon all over the world were gifted with human intelligence. Many turn against humanity, using their powers over the elements to even the score and put humans back in the food chain.
