One of the weakest, but most numerous of the Pureblood Heartless that exist. The Shadows may be weak, but hardly cowrdly and are usually one of the first warnings a place may get if there is to be a sudden incursion of the dark ones within the area. Quantity has a quality all on its own.
This young-looking short woman has gleaming pale-skin, short black hair, and twisted antenna emerging from the front of her head, twitching and writhing . Her legs end in blackened shadow and her feet have no definable toes, simply a single pointed 'foot.' Her arms likewise end in blackened three-fingered claws. An unsettling grin plays on her lips always, despite the light from her eyes that gives off very little emotion. She costantly adopts a hunched over postion and she jumps and twists her body about in-place like in some frantic dance that she only hears the music towards.
Shadow Heartless are one of the most instinctiually-driven of the Heartless, going more for darkened emotions then Spirit Energy or anything like that. They attack anything with a Heart wildly, reckless abandon apparent without care for their ownselves due to their seemingly invincibility when attempted to be damaged by anything non-magical. For the most part, the inital years of a Shadow's life is spent collecting the Hearts of animals and gaining their power, eventually this power grants them more emotions and intelligence. Usually, the more intelligent a creature is, the more potential its Heart has for emotions and therefore, more power and quicker progression for that Heartless.
Shadows have the unqiue ability to bend their body into a 2-dimensional shape, like a shadow on the ground or floor. This allows them to transverse on walls and makes them immune to most conventional magic weapons and spells, even instruments of Light are unable to destroy them in this form. However, they cannot attack or steal Hearts this way and as such only use this as a evasive maunever and can even be knocked out of it if they aren't 'fully' in the ground yet. They can use this ability to hide within other actual shadows and also in shadows of a living thing, though it requires the person's consent before they can 'invade' another person's shadow.
Generally speaking, whenever Shadows gain enough intelligence to speak and understand most languages, they go after with others, potentially as intelligent as them, potentially not. Whatever the case, other Heartless usually join in these swarms to steal Hearts or find potential mates, perhaps both. It is exceedingly rare to encounter a Shadow alone, but for most people, it is no less dangerous and being sighted by one is a good way to be continously chased by them until caught.
Resisting upon being cornered, will usually result in the man in the situation having their Heart immediately tainted and a quick descent to incubidom. Letting them do what they will, well... won't be any more gentle, but they'll be less aggressive and probably won't taint the man's heart. While Shadows are never one for emotions due to their nature, the esctasy they face causes their face to split into wide lewd grins and shake their hips upon the man's cock over and over again, antenna squirming around at their enjoyment. Complete silence breaks out into raspy moans that eventually turn to a delightful chorus.
Shadow Heartless have no problems with harems and will happily swarm inside their man's shadow, only to pop up when needed to defend viciously against perceived threats, dutifully they serve eagerly to indulge in their vices or virtures to gain more and more energy from their Heart and Spirit Energy. More time spent with their man or others will increase their sense-of-self and make them care more than to consume and fuck, their blank slate makes it so their personality can be just about anything.
Shadows, intially, don't make great 'regular' wives and unless an exception proves itself, will have to be taught more basic mannerisms and such things to fit into normal society. Though in the end, that perhaps, will prove most amusing to others, unless one accidentally starts a Heartless plague, than that would be most worrisome.
