>>46548152If this is a trainer/Pokemon relationship, then consent becomes extremely ethically dubious, for similar reasons as a teacher/student or doctor/patient relationship. There's an inherent power imbalance there which makes it all too easy for one party to take advantage of the other.
If a Pokemon is an emancipated being you're able to meet as an equal? Then consent is possible. If you have its Pokeball and the ability to stuff it into a computer should it displease you? That threat of coercion, even if you would never act upon it, erases the possibility of meaningful consent.
