Born between female humans and male demons, doppelgangers appeares as a normal child, but once the child hits the age of 8, other characteristics would begin to appear. This period of time is called "Transference". It is marked by the child's first change of appearance.
In order for a doppelganger to change it's appearence it must first gain the knowlege of who it would like to change into. Doppelgangers are linked to humans while their demonic nature helps intensify this link making them naturally telepathic. It is said that this telepathic ability deteriorates over many years of breeding between doppelgangers until finally the only way to enter a human's mind is physical contact, while before a doppelganger could simply enter a human's mind at will. This physical contact is called the "Doppelganger's Kiss".
The doppelganger must "kiss" the human it wishes to transform into, which may seem unorthadox considering their demonic nature. But it is a necessary action, for the moment the doppelganger's lips touch the human's lips, the information about the human's appearence, thoughts, memories, physical abilities, skills, and talents are transfered to the doppelganger, thus marking the change. Then the doppelganger must kill the human to make the transferrence complete. This is part of the strict code doppelgangers must follow:
Never kill another doppelganger.
Never reveal another doppelganger's identity to any human.
Never reveal oneself to a human.
Never let a human live while simultaneously using their appearance.
These 4 main rules are to ensure the doppelganger race is secret to humans and that the race is kept alive for as long as possible. If this is compromised and if any of the 4 rules are broken, the doppelganger must be hunted down and killed. Usually this is done by a doppelganger who witnesses the other doppelganger's mistake.
Although there have been times in which doppelgangers have revealed themselves to humans, it is very rare. This is because every doppelganger knows the 4 rules and are taught the consequenses at a young age. This teaching is thought to have been passed down over generations starting with the first demons to breed with humans.
Doppelgangers usually travel the earth tansferring from appearence to appearence never being know by humans. Occasionally a doppelganger's path is crossed by another doppelganger. If a male doppelganger meets a female doppelganger, they must produce offspring. It is required to keep the doppelganger line going. A male doppelganger will often kill of any offspring a female had with a mortal or other creature. Though these kinds of offspring are rare occurrences, they are possible and often seen as disgraces among their kind; a female doppelganger will not often fight to stop this murder. This meeting is very rare, which is both the cause and effect of how doppelgangers are rare in general.
Abilities and lessons:
For the first 8 years of a doppelganger's life, he/she is tought everything needed to survive as a doppelganger. These teachings are done by the mother, who usually teaches the child survival techniques. These include acedemic information (liturature, science, math, etc) to better blend into the human society. The doppelganger is also usually taught self defense in case a human were to discover their identity.
At a young age, doppelgangers are taught to kill, usually starting with small animals and moving to more complex adversaries. This is to ensure the doppelganger's survival in adulthood.
Although doppelgangers are taught basics in survival techniques at a young age, it is nothing compared to the knowlege they gain through the years. Each human they take can be used to the full extent. For example, if a doppelganger were to choose a doctor as their next template, they would gain all the medical knowlege the doctor had picked up in his years at college and in the field as well. This would also include any other skills the doctor picked up throughout his life. Perhaps he took a few classes of karate. This skill would transfer to the doppelganger and could be used as such.
Along with the abilities they gain from humans, they also have abilities of their own thanks to their slightly demonic nature. These abilities include enhanced physical strength, agility, speed. and the ability to hide among shadows, scale walls and evaporate into shadows. This, coupled with their extensive knowlege they gained from human victims makes them some of the most dangerous creatures in the world, causing them to underestimate the strength of enemies once encountered..
