Pokemon Online Game: My System Is a Pokemon

(Pokemon + Pokémon + no heroine + System + transmigration + online game + mild changes to the source material. Fans of the original can leave now. This story changes how moves are performed without changing the conditions for Pokémon to learn them, and that's not all.)

A tiny world that originally had Pokémon elements from an anime was suddenly invaded one day by two dark Legendary Pokémon. They erased everything related to Pokémon, and through the influence of their own powers, the consciousness of all humans was corrupted by darkness and forcibly pulled into a game world. This was a crucial step in their plan to conquer the world. Misdreavus was lucky enough to be chosen by a Pokémon and enter the still-unfinished game world before its memories were erased. And so it all began.
