Okay today I learned that flesh flies (which iirc were introduced into Australia by European settlers in the late 1700s, thanks for that) sometimes give birth to living young and when you squash them because they annoy you and you don't want them in your kitchen, they will sometimes explode into a mass of tiny, living maggots, if they happened to have been female and pregnant.
So that means a potential, over-due housefly Pokemon could learn Attack Order/Heal Order/Defense Order, like Vaspiquen.
So yeah, 3 stage Bug/Dark Housefly Pokemon, starting off as a maggot, evolving into a beelzebub like thing that learns Attack/Heal/Defense Order if female.
