The Monster Multiverse

Black Harpy
Harpy Family -- Birdman Type

Habitat: Grasslands, mountains
Disposition: Vicious, ferocious
Diet: Omnivorous, mostly nuts and small animals

A race of harpies with jet-black wings. They are said to be the most intelligent variety. More vicious than normal harpies, they are known to swoop down on passing humans and rob them of food and valuables.

Unlike the other harpy races, this kind is known to bring desirable men back to their nests even outside of mating season. Furthermore, while most harpies release their mates once mating season is over, black harpies "marry" them. The "husband" helps take care of the harpy's other children during her pregnancy and will not be set free until his "wife" gives birth.

Black harpies have a strong sense of community. They are extremely protective of their "husbands" and of others of their kind. If one is attacked, the rest will retaliate as a group.

Black Harpy
Harpy family -- Birdman type

Habitat: Grasslands, mountainous regions
Disposition: Ferocious
Diet: Omnivorous, fruit and wild animals, etc.

A type of harpy that has pitch black wings. Even among the harpy family, they're a highly intelligent and clever race, however, they're ferocious compared to harpies, and they attack humans and human settlements from time to time, stealing food, precious metals and gems, etc., and abducting human men that they like.

The biggest difference from harpies is that harpies fundamentally only assault men during mating season (although they do attack men without hesitation even outside of mating season if they've already established a sexual relationship with them). However, the black harpies will attack whenever they see a man they like and take him back to their nests.

They're ferocious monsters with strong lust for men even outside of mating season. They climb on top and rape men, shaking their hips even more wildly than a harpy in mating season. Most of the harpy family don't keep restraining their men after mating season is over, but they're different because they have a strong sense of “family.” The men that they dragged back to their nests became their husbands at the point when they mated, and as far as they're concerned they're husband and wife, and they always need to stick close together and live together.

And so, when mating season comes, exactly opposite to the harpy, their normally ferocious nature mellows out. Their usual oppressive, overly confident selves are nowhere to be seen. Their bodies flush, and they snuggle up with their husbands, begging for intercourse with wet eyes. During mating season, they're just females that desire to be fertilized by their beloved male.

Black harpies have a strong sense of camaraderie. They treat others extremely well, especially their own family, their husband and children. If a black harpy with friends is being attacked, her friends will appear to help her at once. If her own husband or children are being harmed, she'll exhibit all the ferocity of a monster from the age of the former demon lord as she fights off the enemy.
They're ferocious and rough compared with harpies, but as wives and mothers, they smile gently and softly at their family, their husband and children.
