This strange being is a minor essence fragment of the Alien Energy-being SLAG.
In its natural state is has no form of its own, appearing as a mass of metallic black liquid, typically formed into a pool of puddle, with an average diameter of about 15 ft. Its consistency can vary, but is typically that of quicksand or mud.
If this entity truly possesses an intelligence it seems devoted entirely to hunting, AVERNUS is driven entirely by hunger. It can be a very patient & cunning hunter, setting traps, baiting them, and then waiting for some unfortunate creature to step too close.
It possesses the ability to mimic its surroundings, copying them so as to hide itself from view, and from its prey. Similarly it can meld with inanimate matter; floors, walls, carpets, couches, etc., absorbing into them and assimilating them temporarily. In this fashion it hides itself within said objects, as it lies in wait. It seems quite fond of the executive offices, and is often lying in wait in one of them.
It spreads itself out into a large puddle, or melds with an object, and then just waits for something to come along. As soon as some unfortunate creature walks over its surface, or comes in contact with an object it is melded with, it strikes. It first traps them, and then sucks down them into its seemingly endless depths, where they are absorbed. When it strikes its grip is like cement, as it relentlessly drags its victims down, like a pool of living quicksand. When necessary it can form up tentacles and pseudopods to help subdue more troublesome meals. In short if some hapless creature stumbles into its grasp, say goodbye to them. ;)
Bait: It is capable of creating small objects, seemingly out of thin air, which it uses to lure creatures closer to itself. Typical objects include flowers, candy, jewelry, and small shiny objects.
Other Powers: It's powers & abilities are unknown. It has not demonstrated any powers and abilities aside from those above, & those inherent to its nature.
It is very likely to possess other abilities, which simply have not been seen yet.
-----------
Strictly a predator, especially given its composition(solid energy, indigestable).
Vs Females: Its preferred prey, especially humanoid females. Enjoys willing and unwilling prey equally. With willing prey it can be surprisingly gentle, and usually tries to make the experience as pleasureable as possible for his prey. Even with 'unwilling' prey it usually tries to be as gentle as possible, disliking damaging its food. Almost always leaves its female prey with various gifts & momentos, after it reforms them.
Vs Males: Though it greatly prefers female prey, it will sometimes eat males as well. In the case of male prey, 'unwillingness' is a must, if they do not struggle, or have the taste of fear to them, then typically it won't even bother.
-Always reforms its prey after consuming them.
Note: This form does NOT yiff, so don't ask.
Note: When I say male & female, I refer to the character, not the person playing them. To be honest it doesn't matter to me if the person is of opposite gender to their character. I mean, I'm not exactly an alien energy being in real life.
