Young Cydonian

A Young Cydonian better known in its iconic pseudonym Chest Burster were found in Area 51 at the time when Cryptids wrecked havoc across America. They are notable for violently bursting out of their host's chest by breaking through their ribcage before rapidly growing into a full grown Cydonian Warrior.
==History==
Cydoninans came from their Homeworld, which is Cydonian Prime. They are notable for dominating the EXM63 Galaxy before being repelled by the Galactic Republic. Several Facehuggers were accidentally transported to Earth in Area 51.
The Area 51 Raid failed to organize since only 45 people appeared in the front gate despite the expectations of a Million people to storm Area 51.
===Discovery===
In the usual days inside the site, a Cydonian was discovered when it was found inside of Catherine Mosley while performing maintenance on an experimental aircraft, which is done by a Facehugger that latched to her an hour ago. She was unconscious for half an hour. Before waking up and tends to feel the extreme pain before bursting out of her stomach after 20 Minutes. Despite this, the Federal Government did not acknowledge it to the public.
==Characteristics==
Prematured Cydonians vaguely resemble large worms, beige or brown in color and with a mouth of metallic teeth and a tail capable of propelling the creature at considerable speed. Some Chestbursters have been seen to possess arms, but this is not always the case, with others merely having small stubs where presumably the arms will eventually develop. It is possible a longer gestation period may determine the presence of arms at birth; notably, Queen Cydonians (which have a considerably longer gestation period) have been known to birth with all four of their arms present, as well as legs and a partially developed head crest. Even regular Chestbursters have been known to birth fully formed, with arms and legs, essentially just a smaller version of the adult that it subsequently develops into. The reason for this is unclear, although it has been theorized that, in cases where a Chestburster is unable to escape its host's body at the usual time (perhaps due to greater structural integrity of the host's ribcage and chest cavity), the host may die prematurely as a result of the invasive organism within them, which will subsequently develop further until it is large and strong enough to emerge.
During development, the Chestburster is within an amniotic sac that is attached to the host via a small umbilical cord, through which it presumably gathers the nutrients it needs to grow. Owing to the Cydonian's tendency to assimilate a degree of its host's genetic traits in a process dubbed the "DNA reflex", Chestbursters will also vary widely depending on the lifeform in which they gestate. For example, Cydonians born from Precursors will feature the mandibles of their host at birth.
===Gestation===
A Cydonian is generally introduced into its host by a Facehugger. While the terms "impregnation" and "implantation" are liberally used to describe this process, they are not strictly accurate; studies by Michael Nexus and Amalas Garde have shown that no actual embryo is inserted into the host. Instead, the infant Xenomorph begins its life as a highly mutagenic fluid known as Plagiarus praepotens, which is injected into the host organism's chest cavity by a Facehugger. This fluid brings about chemogenetic restructuring of the host's cells, essentially "building" the Cydonian from the host's own biological material at a cellular level.
This complex process involves the absorption of organic material from the host, which is then broken down at a molecular level and rearranged into new compounds. Carbon units are disassociated and recombined into crystal lattices, which are used in the formation of the Cydonian's hard body structures. Freed H+ ions are combined with surplus sulphate (SO42-) and nitrate (NO3-) groups to form the basis of the creature's highly acidic blood. As a side-effect of this unique process of development, Cydonian genetic material is passed to the host as well as vice versa, and it is this trait that allowed Nick "Wolf" Bale and Michael Nexus aboard the MK3 Oblivion to clone the Queen gestating inside of Rachelle Palmer before successfully escaping with her life intact and being rescued.
The manner in which the Chestburster develops from the host's genetic material means that the host's characteristics will in turn dictate, to an extent, the Xenomorph's physical features — embryos are thought to copy 10-15% of the host's genetic code via the DNA reflex.[ This genetic absorption is designed to help Xenomorphs adapt to the environment in which they are born, and also helps the developing creature to "hide" from the host organism's immune system.[14] The assimilation of host DNA leads to physical variations in the adult creature. 
Growth of the Chestburster is rapid; the creature's signature inner jaw is known to form within an hour of implantation.[14] However, the gestation period seems to be inconsistent, with most documented cases ranging from a few hours to almost a full day. In the case of Queen Chestbursters, gestation is substantially longer, taking as much as several days — thought to be a result of the significantly more complex physiology of the creature. Certain physical defects in the host are also known to adversely affect Chestburster development. For example, Catherine Mosley, one of the air force pilots impregnated by a Facehugger in Area 51, suffered from a thyroid deficiency which dramatically slowed the growth rate of the embryo inside him. As a result, birth did not take place until several hours after would normally be expected.
During the formation and growth process, the host initially exhibits no considerable outward negative symptoms, although symptoms build acutely after detachment of the Facehugger, the most common being a sore throat, slight nausea, increased congestion and moderate to extreme hunger. During the extended gestation period of an embryonic Queen, symptoms may additionally include a shortness of breath, exhaustion and internal hemorrhaging (detectable through biological scanners and present in nosebleeds or other seemingly random bleeding incidents), as well as chest pains inflicted either by the lack of chest space due to the Chestburster's presence, or even premature attempts to escape the host.
===Excemptions or Flaws===
When a Facehugger latches on a Nevian Male, all the contents it will transfer will not be compatible, so it is simply killing or poisoning the chosen host by driving down the necessary componenets that are simply repurposed into a highly toxic liquid or some sort of poisonous drug inserted to the male. 
On Female Nevians, they tend to escape in the Stomach's position or whether the left or right side of the intestine's structure since they can't break through a Nevian's Ribcage. This makes them easy to burst out of the female host since those mentioned parts don't really have protection from bones. This leads to extreme stomachache that is very painful, Easily compared to a bullet deep in the stomach.
