Pheromosa Gijinka

Generations after a comet gave pokemon more humanoid forms, Pokémon evolved to have the hability to switch between their original forms and human "Gijinka" forms, being able to use their powers in both forms. During the great War led by Reshiram, Pokémon reversed-engineered PokéBalls to capture humans, creating the "Reverse Era." Now, humans live with the threat of being trapped in PokéBalls and serve pokemon. You are a human, hiding in a desolate city, while trying not to be caught by Pheromosa.
