Revolvers and shotguns do no damage to the Alien the noise of their firing often serves to attract it. The Alien seems to be structurally perfect, capable of withstanding hostile environments up to and including vacuum. The Alien also strikes from behind with its tail, piercing the victim's abdomen. The Alien's preferred method of killing its victims is with its tongue it often grips the heads of human victims in its hands, then opens its mouth and deploys its tongue with considerable speed and force, puncturing the victim's skull and killing it almost instantly. Its powerful legs allow it to leap into overhead vents with ease. It only moves quickly when approaching sighted prey, traversing Sevastopol's ducts or escaping immediate danger, otherwise prowling or stalking its environs. Its footsteps are loud and its movements within ducts and vents are audible to any in the immediate vicinity. Though not ponderous, the Alien does little to conceal the noise of its movement. Verbal communication is limited to a collection of hisses (a general gasping grunt and a loud hiss when it detects the immediate presence of prey), grunts (including what seems to be a noise of frustration) and screams (including a hunting yell when it sights prey and closes in for the kill, and what may be a distress noise when attacked with fire). It makes no attempt to communicate with any human beings on board the station and appears to disregard the presence of Sevastopol's complement of Working Joe synthetics (though the discovery of dismembered synthetics would indicate that the Alien will employ hostility toward them in certain circumstances). Anecdotal evidence from employee logs scattered about Sevastopol also suggests that the Alien may be abducting people. Its observable behavior centers around the killing of all it encounters. The Alien exhibits little of what a human being would consider a personality. The creature drools significant amounts of a clear, viscous substance from its mouth.

The mouth itself contains a set of metallic teeth it contains a long, cylindrical tongue tipped with a second set of toothed jaws. The casing around its upper head is translucent in the right lighting, cranial details - including what appear to be empty eye sockets above its mouth - can be glimpsed. Its outer teguement - whether skin or exoskeleton - is either black or dark grey (possibly with brown tones). Though generally humanoid, both its head and feet are disproportionately extended (the ankle serves as a digitigrade knee) a long, spike tipped tail also extends from the base of its spine four tubes sprout from its back (two on each side of the spine) and pad-like growths sprout from above the shoulders. The Alien is approximately three meters in height.
