Notes


Eve symbiote
Highly adaptable alien life form - can form a symbiotic relationship with any mammals.

Stages of life:

Egg state - when an adult Eve gives birth, instead of a baby (or egg in some cases) of whatever animal it forms its symbiotic relationship with, an Eve egg will come out. This egg have a soft, but thick, mucous outer shell that protects an hibernated Eve larva within along with a nutrious fluid. The mucus have adhesive property, allowing for the egg to be placed almost on any surface by the adult Eve, and remains adhesive even underwater. The adhesive mucus also allow debris from the environment to stick on and form a camouflage for the egg. This mucus will eventually harden and form a protective shell for the egg. An egg can last up to 10 years in this state before being spoiled.

Larva stage - When an Eve larva detects a suitable host/mate nearby its egg , it will become active and hatch from its egg. It is still unknown as to how the larva can detects its host/mate from within its eggs, but scientists believe that the pheromones of a fertile host/mate may cause subtle chemical changes within the eggs and cause the larva to be awaken. This is because a mate that already formed a relationship with another Eve will also have a special type of pheromone being coated upon its body by the Eve, and this seems to prevent an egg from hatching. While Eve larvae prefer male host for reasons that will be described later, there has been cases where female host has been chosen when an Eve egg is nearing expiration and its larva become desperate for survival.

A larva Eve is insect-like in appearance, sizes ranging from 10-15 cm, with soft shell - almost skin like, 6 pointed legs that can move at high speed and jump for tremendous height, and a large pair of sharp mandibles. At this stage, its genes is its own, or more specifically, a collection of very long genes that resemble its ancestor, but with significant parts missing - this is to allow it to accommodate to its future host's genes. It has no visible eyes, suggesting that it is blind, however it is able to track down its host/mate by a series of scent receptacles along its body which can detects pheromones. After discovering a host, it will temporarily subdue the host by latching on the host body and inject a powerful sedative with its mandible. Despite having characteristics of a hunting insect such as the mandibles , the Eve larva is not a predator. It has no digestive system of its own, instead most of its body is a crude form of the reproductive organ that an adult Eve has. Thus it cannot hunt and consume preys. Its mandibles is meant to inject the sedative to subdue hosts, and then to make incision on the skin of its host to accommodate burrowing, and they secrete a special anesthesia that also sterilize the wound and promote healing. Although they can burrow anywhere on the host body, they will attempt to choose a part that will not hinder the host during its chrysalis stage. Upon successful burrowing, the larva start fusing into the host's nervous and circulatory system and begins its chrysalis stage.

Chrysalis stage - This is the most vulnerable stage for both the host and the symbiote. The symbiote first copies part of genetic materials of the host, then mutate it into its own to form a complete set of genes similar, but distinctively alien comparing to the host. After this , it hijacks part of the host's own genes and mutate it, causing a benign version of cancer that produce cells very similar to stem cell, which will later grown into the body of the adult Eve. During this process, it also repair any defects that it's host's genes may have. After successfully form its own set of genes and mutate parts of its host's, the symbiote start growing a chrysalis from where the larvae burrowed , made up by part of the host own skin and cancerous cell in control by the symbiote. It then create a clone of the host within the chrysalis, only that it is female. This is due to the fact that the Eve symbiote copies parts of its host's genetic material, including sex chromosomes, through cloning one half , making a mirror copy then mutate that second part , which means it can only be XX or YY, with 1X or Y being the alien copy. As YY is not possible nor suitable for reproduction, those chromosomes will quickly be discarded, thus leaving only XX, causing them to always be female. This alien life form has evolved to adapt to this fact through its behaviors.
The symbiote in this stage is mostly passive, but studies shows distinct behavior changes within the host such as increasing intake of nutrition, forming stashes of food even if it is uncharacteristic for the host's behavior, varied diets - most host will be less picky about what they eat and eat more type of food that they are capable to digest for energy. These changes suggests that the symbiote may have take control part of the host's nervous system to ensure the survival of both.

The symbiote's growth rate is dependant on the host's complexity and nutrition intake.

In the wild, the length of chrysalis stage can be anywhere between 2-3 months for an average size animal such as a horse. Small animal like dogs take about 2-4 weeks. Large animal such as an elephant may take up to half a year or more. In these cases, usually the chrysalis will grow parts of the final body at a time from the chrysalis instead of the whole body at once, which will look almost like a case of joined twins at a glance. As the symbiote is fused with the nervous system of the host's body, the host can actually use these extra body parts until the chyrsalis matured and the symbiote finally sperate from its host, however these uses are very limited without training. Thus, they become more of a liability for the host, and may cause difficulty for survival. Nearing the end of the chrysalis state, the host is forced into hiding and go into hibernation, whether the host is a creature with hibernation behaviour or not, for the completion of the chrysalis stage. As soon as the body is fully formed, the symbiote will awaken and begin to separate from the host. By this time, the symbiote's body has became a near perfect copy of its host body with its own complex nervous, circulatory and digestive system similar to its host, with most of its link to the host severed except for a thin layer of skin cells connecting them, before that too is separated by the awakened symbiote by forcefully ripping itself off the host. The remains of the chrysalis will then form a scar over this wound on both the host and the adult Eve and heal them.

In controlled environments where nutritions are provided abundantly, the symbiote will forces the host into hibernation much sooner, nearing the beginning, only to wake up to eat or get rid of waste, before returning to hibernate. In this case, the grow rate is sped up significantly, almost half the time needed for normal growth. 3 weeks to 1.5 months for average-sized animals, 1-2 weeks for small animals, and 3-4 months for large animals. When growing this way, instead of having parts of the adult body grow separately, the symbiote will form a much larger chrysalis, taking over most of its host's body area as a result and grow the whole clone body at once like a pseudo womb . The end result would be also less messy, as the bodies will fully separated in the chrysalis before the symbiote wakes up. At the final moment of this chrysalis state, the chrysalis will pop itself open, releasing the adult Eve symbiote inside along with some amount of nutritious fluid similar to one inside an Eve egg before withering and peel itself off the host within a feel days if left untouched.

Adult stage - An adult Eve will be almost indistinguishable from another member of its host's species, and easily blend into the rest with its appearance. Although a way to discover Eves are by checking the amount of twins within a population, because Eves create their adult bodies by cloning most of their hosts genetic material, thus their outward appearances will also be very similar to their hosts, like twins.

Most of the organs within the adult Eve will be characteristic to its host's species in term of appearance and functions, with the sole exception of the reproductive system, which remains alien, although there are some minimal resemblance to a normal organ of another female member of its host species. However, they can only bear an Eve egg with this reproductive system.

At the cellular level, Eves are completely different than their hosts. Each of their cells is a microorganism that can act independently, helping the main body altering its shape to suit the host/ mate's preferences. While they cannot do something so insanely complex like shape shifting to a whole different form, this still allow them to dramatically alter their body structures in a short time with their own will, such as increasing/decreasing body mass, changing fat/muscles percentages of their body, reshaping their skeletons (things like widening/narrowing their hips), and such. This allow them to maintain a perfect body shape and a fertile, youthful appearance for most of their lifespan to remains the "perfect mate" for their host/mate.

An Eve lifespan is, on average, as long as its host/mate. Despite its body being able to live much longer than its host/mate all of its cells start their dying sequence soon after the death of its host/mate.There is still no explanation as to why they do this, as they can still survive within the host’s community as a member.

Behaviors

An Eve adapts its host/mate behaviour to live, and thus does not differ much from other members of its host/mate's species. However, it is noted that Eves have much higher libido than a normal female, and will sometime even take initiation in mating with its host/mate even if that species' females are unlikely to engage in such behaviours.

An adult Eve cannot use its own mutated genetic material alone to form a new egg, despite having parts of its host/mate in there. Instead it must takes new material from the semen of its host/mate which then will be broken down and fused with its own broken down genetic material within the alien reproductive organ, creating the basics of the Eve larva's genes. This makes the new larva twice mutated from the host, ensuring the offspring can mate with another normal offspring of its host if needed while preventing the negative effect of inbreeding. An egg can be produced every 2 months if the symbiote mate regularly.

Eves seems to have superior intelligent than most of its simple hosts/mate, capable of learning basic survival skills often taught by parents to child extremely fast, and just through observation. Even with higher intelligence life forms hosts/mates like primates, Eves still have above average intelligence,solving basic problems much faster than most other members of its host/mate's species.
The only exception is with human, where the Eves’ intelligence is limited to that of a 6 years old human child. Apparently their intelligence only serve to keeping themselves alive and breeding but not more.
