Join Ash accompanied by his partner Pikachu, as he travels through many regions, meets new friends and faces new challenges on his quest to become a Pokémon Master.
In 2071, roughly fifty years after an accident with a hyperspace gateway made the Earth almost uninhabitable, humanity has colonized most of the rocky planets and moons of the Solar System. Amid a rising crime rate, the Inter Solar System Police (ISSP) set up a legalized contract system, in which registered bounty hunters, also referred to as "Cowboys", chase criminals and bring them in alive in return for a reward.
Determined to prove its superiority, a bio-engineered Pokémon called Mewtwo lures Ash, Pikachu and others into a Pokemon match like none before.
