Team Starfall and the Crystal Legend (Pokémon Mystery Dungeon x Lucario reader)

A/n: So, I played Pokémon Super Mystery Dungeon and thought of making my own story for it, just for fun. Pokémon and Pokémon Mystery Dungeon are owned by Nintendo, Game Freak, and other companies, please support the official release.

Darius, a boy who was sent to the Pokémon world, and turned into a Riolu, by a legendary to help the world from an impending doom. He meets a Fennekin name Serena and a Buneary named Cotty. Together, they meet new friends and rival and stop evil organizations, threatening to rule/destroy the world. What adventures will they have.....and what is the crystal legend...?
