A floating bulk of white mist and place less stitches. It's tendrils reach for you, and you are his.
The condensed mass of souls that comprise it's hull give off an aura of sadness and despair. Tendrils reach randomly from stitches that open and close at whim, their color a slightly gray offset of the hull's.
Evil and sadistic, it lives only to wreck and cause havok. The only possible good side to it's personality is it's sick playful sense of humor. It's only long time aquaintances are those it did not kill straight away.
The stitches running in and along the cloud of it's body can open up to allow a variety of tools to form. When in combat (or just for fun) it may produce tendrils of hateful incartation that can be used as blunt mellee weapons, soul grabbing appendages (if no anti-spirit armor is worn), or weapon mimics (anything from lazer weapons to mage staffs). When bored, and wanting to start something, it may open it's stitches to pour out various types of evil aura mists. These include, but are not limited to: A black violence cloud aura, A cold sadness aura, A bright red lust cloud aura.
For deception (or just for socializing in his evil way) it may incarnate itself as a sophisticated-looking victorian man in a top hat. To many this incarnation is known as "The Devil's Buisinessman" as he often will persuade people to sign their souls away in contract.
Borne of the fire of hell and hate, It seeks general absorbsion and assimalation of all manner of creature, robot, or spirit. Only those who are holy in spirit may resist it's influence and attraction.
