Pokémon Mystery Dungeon: Waves of Destruction

Getting turned into a Pokémon and sent to a new world is one thing. Your brother being sent there too is an entirely different matter. But if Agatha has to search every corner of this new world for Jack, she's going to do it. Even if it means having to team up with a shady gang of mercenaries who are bent on making the organizations of this new world look as bad as possible.
