A killing machine, plain and simple. Perfect hunter and adapter. Skin was slick and had a slimey quality, almost like orca skin. Ebony all over, perfect for blending with the darkness that inhibits so many creatures. Slick head was elongated and smooth, no eyes or ears visible. Sightless, the alien hunted by scent and vibration. Movable lips harbored silver teeth, jaw able to crush bone like it was paper. Within the maw no tongue would be found, only a second extendable maw found, considerably smaller yet still with silver teeth. Exoskeleton that held the alien together was impervial to fists, only weapons with a good projectile force could penetrate. Having slight humanoid build it stood upright, arms slender yet strong. Hands were long fingered, only four visible. Thumb and pinky were short while index and middle were very long, ending in talons. 'Spikes' portruded from its back, easily three feet long, the alien itself standing about six feet tall. Legs were bent like a birds almost, feet ending in long blunt toes. Most dangerous external weapon was its tail. A good five feet long it was whip-like and ended in a spade sharper than any dagger man, beast, or ungod immortal had crafted thus far, it could slice steel easily. Most were not keen to penetrate the creatures exoskeleton for what ran through the alien's veins. Its blood was acidic, thus assuring the predator would not become prey easily unless by its own kind. The acid could melt anything but glass, as is the usual manner of acid.
