Ghost - Spirit
According to the most recent anime ending “Super-Effective Type,” Dark-type Pokémon are classified as such due to their desire to prank and deceive others:
>Dark is super effective against Ghost. They can play pranks even on things they can't see.These Zorua and Zoroark do not prank people for fun; they only cast illusions now out of their malice of having been killed by humans and Pokémon, the same malice that brought them back from the dead and resulted in them incorporating ethereal corpses. The Dark energy is now Ghost energy. The corporeal bodies they have now are because the Dark Zorua is dead and they are just a corpse, being Normal.
Normal is the body, and Ghost is the spirit. Spiritomb, an actual Ghost/Dark Pokémon, does not have a proper body and it is just a collection of spirits.
