Although all Pokémon up to the third generation can be recruited, some have to be unlocked by completing a certain mission first. The version exclusives for each game are those Pokémon whose pre-recruitment missions occur naturally. To obtain the Pokémon in the other version, you must use the Wonder Mail code for the relvant mission.
