1. クチート Kucheat (Mawile)
The kucheat is a small pokemon that looks cute with its round face and small eyes but it has a giant jaw on the back of its head. This is much like the futakuchi onna.
They appear as beautiful women who seems to not eat anything and is very quiet. You won’t know that she is a yokai. But you will notice that the food supply would slowly start to deplete. Yes, the yokai has another mouth on the back of her head and this mouth would demand food as it has an insatiable hunger. It could also control the woman’s hair and use it like hands.
But lucky for the kucheat, rather than a nuisance, the jaw could be used for fighting.
