That said, girlish machine thing = Steel/Fairy shouldn't be that much of a surprise. Obviously, they are promoting the Fairy-type and so on, but hopefully it doesn't just do that. Because it's quite a finnicky type, they're likely to have to adapt to this in the present circumstances, however. It might make more sense to have it be later-game, because of the resistances meaning that it might be a bit peculiar if you aren't given time to adapt to such things first.
