Meh, pokemon personification are often very vague.
Yes, we have here a character that appears in the game but for all personification of pokemon they (the pokemon) turned into something humanoid or the character has clothes that matches the pokemon's appearance.
But I can get along with objectification as well but's it's a border case or something like that.
So I think personification counts when the pokemon is turned into an original character.
But cosplay is indeed the best solution
