Dark Unicorns

When a Unicorn and a Nightmare mate, there is a possibility to make a Dark Unicorn. Also known as the Black Unicorn, Battle Unicorn, or a Demon Unicorns, they are to be feared by many.

They look much like both their mothers in a lot of ways. They have the body of a dark horse from the waist down, and the body of a voluptuous woman from the waist up. The woman half always has darker hair that could come in unnatural colors, with a black horn that has some dark colored accents, and eyes that are pure black besides a ring of color, the color mirroring the accents of their horn.

They are naturally gived with several magics, ranging from the more demonic kinds like fire magic and demon magic, to the more unicorn based like earth and nature magic. But the one magic they gain naturally from birth is Dark Light Magic, a magic they only can use. It is a sort of shadow magic that can both blind and cloak. It's major uses are blinding enemies, cloaking yourself and/or others of significant interest, plunging areas into pitch black or blinding light, night vision, and a sort of minor teleportation that plunge the Dark Unicorn from a shadow to another shadow that is in their line of sight.

From there, how they act is determined by their mother. If their raised by a Unicorn, they are more like guardians, watching over the herd and becoming Matrons of the herd in most cases. If their raised by a Unicorn Matron, they become some of the most dangerous futas around, even able to compete with a young dragon or a young Manto-chimera in a fair fight. They are referred to as Battle Unicorns. The ones raised by Nightmares, however, gain a bit more. They are usually prized beasts of the Demons, and also have a bit of fire around their hooves and eyes, and are called Demon Unicorns, they are only rode by the commanders of great demon armies or harems, as they are more feared than even Nightmares by most, to the point Abigors avoid them due to not being able to tame them, and the repeated ruthless ass fuckings they give. The same can be said for the Geryon raised variants, only their flames are blue and their ability to warp time makes them a more dangerous foe even for demon lords.

Geryon and Matron born Dark Unicorns are the most dangerous of their kind. They are known as Void Unicorns and even Demon lords are wary of these time warping, bitch breaking equine monsters to the point most avoid them like the Abigors. Their breeding stud mentalities certainly don't help make them approachable. Not only are they gifted with unrivaled strength and magical might among their kind, they're also born with sizable assets, cocks comparable to those of dragons and chimeras, with curves that put Holstaurs to shame.
