I'm spanish, and I thinked that you were wrong saying that about the Multiplayer thing, so I checked in the Spanish website and it says:
>Muchos de los Pokémon contra los que te enfrentes serán salvajes, es decir, viajan sin un Entrenador que los acompañe. Puedes encontrártelos fácilmente en la hierba alta que hay a las afueras de pueblos y ciudades.
Literally, "viajan sin un Entrenador que los acompañe" translates as "traveling without A Trainer to accompany them."
>yfw a Spanish has better English reading comprehension than those who speak English as their native language
