Alien (xenomorph)

The "xenomorph" type, or aliens, is one of the life forms in the Galaxy. They include many subspecies. They live in different parts of the Galaxy, subdividing into closed cells - hives. According to scientists, each hive has a collective mind that unites all members of the community into a single telepathic network. According to observations, individual xenomorphs are endowed with adaptive intelligence and are capable of learning. This type of aliens is extremely dangerous for most other races, since it reproduces by parasitism with the subsequent destruction of the host and partial borrowing of its morphology. Suitable species of fauna are nothing more than a consumer product for aliens. Most of the bodily fluids of xenomorphs are toxic, and their blood is a molecular acid that corrodes even very chemically resistant materials. Xenomorphs are not a highly evolved alien race: they are creatures with strong predatory instincts, with no higher purpose beyond spreading their presence and destroying any life form that threatens their existence. Despite this, xenomorphs do have a clear social hierarchy in the form of castes, similar to that of wasps or bees. Another feature of this race is the presence of acidic blood and a pharyngeal jaw. When alone or in small numbers, xenomorphs act stealthily, preferring to ambush their victims, but in large numbers they successfully employ swarm tactics, attacking hostile life forms outright. Despite their seemingly insatiable thirst for killing, the creatures often take the opportunity to take their victims alive in order to make them hosts for new xenomorphs. Captured creatures are taken to the Hive (or any secluded location if there is no Hive), where they are immobilized for easier entry into the xenomorph embryo.

When upright, Xenomorphs vaguely resemble bipedal creatures standing 2-3 meters tall, though they often adopt a hunched quadrupedal stance for rapid movement. Their bodies are given a perfectly biomechanical skeletal appearance, and are covered in skin with muted shades of colors such as black or blue. Xenomorphs do not emit excessive heat. In most of their appearances, Xenomorphs can sneak or even run along ceilings and walls. They possess great physical strength, with which they can break down air vents, smash through steel doors, or even destroy reinforced sealed doors. As predators, Xenomorphs are given an arsenal of deadly devices, the most dangerous of which is their second, intrapharyngeal, jaw, which can shoot out of their mouth like a piston; the force exerted is so great that the jaw can easily pierce bone and metal. In practice, before killing a victim in this way, the xenomorph will often grab it with its hands, depriving it of the ability to move, after which it will deliver a precise blow to the head with its intrapharyngeal jaw, piercing the skull and penetrating the brain tissue; this type of killing is often called a "head bite". In some cases, they have killed victims by delivering such blows directly from the ceiling. The next device for killing xenomorphs is their segmented tail with a blade-shaped tip. The tail can be used by xenomorphs not only as a stabbing and cutting weapon, but also as a blunt weapon with which to knock opponents off their feet and even beat them to death.

In addition to developing their own intelligence, xenomorphs are capable of inheriting at least the most basic behavior patterns of their hosts. Xenomorphs are capable of learning to overcome difficulties and obstacles that they face. They are potentially capable of learning to operate various mechanisms at an extremely simple level. The means by which xenomorphs are able to communicate with each other is still unclear, although all their behavior indicates that they are capable of it. Despite the ability to make hissing and screaming sounds, their primary method of communication is not these at all, but another method of interaction - it is assumed that it may be related to pheromones or even some form of telepathy or empathy.
