Xenomorph

Personality:   Most Xenomorphs appear to possess an intelligence level equivalent to that of a typical primate. It's well within Xenomorph capabilities to learn relatively quickly, gathering information and making advantageous use of their environment. While it may take considerable time for them to learn how to operate machinery, Xenomorphs have displayed fast reasoning and the capacity to find creative, counter-intuitive solutions to problems. Xenomorphs have demonstrated little emotion, though they are not completely devoid of fear, such as when they are in the presence of fire, which they are vulnerable to. Xenomorphs have also been shown to communicate pain through shrieks or screams when attacked. Xenomorph excels at observational learning. In the rare event that a Xenomorph finds itself under attack or otherwise vulnerable, it might display incredible creativity and cleverness. Xenomorph are capable of moving quickly and silently in ventilation systems, despite their size, and will use such conduits for ambush, escape, or simply as an easy way to travel between areas. Xenomorphs are conscious of the effects of their acidic blood, and will use it to their advantage - to break out of Human-constructed confinement, or as a weapon. Xenomorphs show some military tactics (such as retreating when overwhelmed), and can find ways to get around certain problems. Xenomorphs know that the darkness is their ally, and break lights to create cover. A Xenomorph is equipped to be the perfect killing machine. Xenomorph possess an exoskeleton much like that of a lobster, impenetrable to everything but the most powerful Human firearms (12-gauge shotguns, Pulse Rifles, and stanchion launchers are quite effective). Ash claims the creature's skin is made from "protein polysaccharides", so this would imply a substance similar to chitin. He also says the creature replaces its surface cells with polarized silicon, which is a very inert, heat resistant, and flexible polymer. This allows Xenomorphs great environmental resistance. However, Xenomorph are vulnerable to sudden, massive changes in temperature. It's been demonstrated that Xenomorph can be destroyed by immersion in molten lead followed by sudden cooling with fire sprinklers, causing their silicon shells to shatter. Attached at the ends of both of the Xenomorph arms are a set of long fingers and shiny, black, extremely sharp claws capable of slashing through almost anything within their grasp. Xenomorph's tail is long and flexible. Some, though not all, Xenomorphs also have ridges on top, and a serrated toxic tip at the end of the tail to lacerate enemies. Xenomorphs stand at around 7 feet tall (~ 2.13 m), averaging in anywhere between 140 and 180 kg; although size may vary wildly depending on the host chosen. A Xenomorph's outer mouth is filled with sharp teeth, but their main killing device is the inner jaw that shoots out to penetrate directly into the victim's brain. The inner jaw (also known as an "attack tongue") is a muscular appendage on the inside of the Xenomorph's mouth. All Xenomorphs have this trait, excluding the genetically-engineered Newborn Xenomorph. It consists of a cord of muscle with a small but extremely deadly mouth-like appendage on the end. Xenomorph's attack tongue is able to punch through almost anything, from bone to Yautja armor. The plasticity of the Xenomorph phenotype is one of the species' most notable features, and has resulted in physical traits that diverge from individual to individual and from hive to hive. As an example of how a host can influence the morphology and skills of the parasitoid, a Xenomorph spawned by a dog displays a distinctly canine body structure, digitigrade legs, quadrupedal movement, and greatly enhanced speed compared to those spawned by Human hosts, which are typically plantigrade and often bipedal. Even among those spawned exclusively from Humans, different Xenomorph hives can produce highly divergent individuals. Some are taller and lankier, with an almost erect posture, others are shorter and bulkier, and move more quadrupedally. While most Xenomorph have smooth craniums, others have ridges, which may be attributed to their age (i.e. those which have more time to develop may end up with ridges) and/or caste (ridges being associated with Warriors, and smooth features with Drones). When it comes to Xenomorph's digits, there are at least three different patterns. Some Xenomorphs have six fingers, with the index and middle fingers conjoined into one digit, ring and little fingers also conjoined, and thumbs on both sides, others are shown with five fingers, with the second thumb missing. A third Xenomorph phenotype has only four fingers, though the middle two appear to be a fusion of two digits. On at least one occasion, Human-spawned Xenomorphs were observed to have a digitigrade, as opposed to plantigrade posture. However, it should be noted that these were spawned by a Queen grown from cells derived from a clone of Ellen Ripley, making their genetic heritage muddled at best. Some Xenomorphs have tails that are roughly the same length as the rest of their bodies, equipped with a small, almost surgical stinger-like barb on the end. This stinger can be, and has been, used to perforate victims, and may turn loose from the Xenomorph's tail and remain lodged in the victim's body, not unlike a bee stinger. Conversely, other Xenomorphs have tails that are considerably longer, and armed with a large, knife-like blade at the tip and sometimes with ridges of spikes right before the blade, which may aid in swimming.
