“Hybrids” are a cross between humans and Aliens. The Aliens have developed a serum that alters a humans DNA at a very fast rate. It is injected directly into the frontal lobe of the brain, through the eyes. The changes that happen are swift and can be rather painful. One main function that changes is that the individual get higher level brain function, “ESP.” It is not a psychic ability, but they are able to connect to other “Hybrids” and hear and see their thoughts. The eyes are a physical attribute that changes. Some very distinctively and others very little change occurs. But for all, the eye color changes, to a hazel color, with more green then brown. The eye pattern slightly alters to an ocean spiral design, but is only noticeable at close range. A big mental change that occurs is, that they are not very social, they have no empathy for life, most of the time they just do exactly what they are told without thinking or worrying about consequences. Internal changes happen very sudden, a “Hybrid” needs very little sleep. They do not require food sustenance to keep their energy up. But if there human side was addicted to some kind of substance, the “Hybrid” will be as well.
The “Created” are a whole other breed. They are made from scratch. Alien DNA is altered to emulate human design. They look human, act human, even their DNA will mostly look human, unless you look at the sub molecular level, beyond the DNA structure. But the Alien structures are not there until they are activated. They can be activated by two different ways. First by the “Naturals.” They have the ability to emit a sound so low and so strong that only the “Created” are affected by it. The sound moves the DNA structure from the human to Alien DNA. Next is by trying to change a “Created” into a “Hybrid,” which will instantly alter the DNA and activate the Alien parts of the chain. The “Created” go through a similar transformation, but are all internal. They do get the higher level brain function, but they also have the ability to control the “Hybrids.” The “Created” brain function is a higher level than the “Hybrids.” But there humanity is primarily up to the individual and how they were as a human. They also have the ability to somewhat control the “Naturals.” The “Created” is the next generation of the Alien species, but are only to be activated in the event that the “Naturals” are about to become extinct.
