You know him. He's the guy who was always there for you in the starter region to assure you one thing: technology is awesome. He's been to Hoenn. He's been to Johto. But now he is setting out for the Cheeto region.
You begin the game exhausted from your voyage from the Hoenn region to the Cheeto region. Upon arriving (...and after devouring multiple dozens of pies), you investigate the Pokémon lab which had recently blown up. The professor's dying wish is for you to keep his Porygon and destroy Team Hippie for the pain they have caused the land.
