Hybrida: Taken at a young age of three to five, human children go through rigorous genetic rewrite and combat training. The Process is agonizing to the subjects undergoing the rewrite, as their whole skeletal system is being rebuilt by the mutation.
Due to the genetic rewrite from being inject numerous times with a human engineered Retrovirus made up of Celestian DNA and RNA, they became extremely intelligent and adaptive to environments, and can access and adapt Celestian tech to their own use.
Not all Hybrida are created artificially, as quite a few mate and bring into the world what are called "True Hybrida" by their peers and scientists.
Their eyes take on a silvery look, taking up the iris and pupil. They tend to grow a head taller than the average human, and their legs become bowed at the shins. Their canines become fanged, and their skin get a scaly like feature.
Hybrida have only one blood type, and can not have human blood infused with theirs. They can only accept blood from their own due to the rewrite and mutation. Their cells develop a nucleus, much like most of Earth's avian species. Their blood is also blue instead of the usual red, also a factor of the mutation/rewrite.
Although, being artificially created, they still have the ability to reproduce, allowing them to have true Hybrida. Mating is the same as humans, except it's more of a sacred manner to them. There is no casual sex. When they mate, it's for life, and is a trust matter. Now mates can still have sex for pleasure, but never with others, unless consented by their mate. it's a more emotional connection than a physical.
Hybrida are also able to mate with humans making their offspring stronger. The father's antibodies and traits are passed on. Although the offspring has both human and hybrida traits, they are known to be called "Halfbreeds" or "Psudo-hybrida"
As for the Muscular system, they are considered weaker than the average soldier, but make up for it in agility, Adaptability, and endurance.
Because of their genes being rewritten, they are considered their own race, and relationships between humans and Hybrida are considered taboo. The thought of loving a being that resembles a threat to humanity tends to be daunting.
Hybrida are very emotional, and tend become attached to their loved ones and friends. They also show an Undying loyalty to their friends and loved ones, and are willing to jump on a grenade if ordered to by one they trust. When a Hybrida sees a loved one being threatened or attacked, they go into a rage that tends to be fatal to the attacker.
Hybrida form tight nit groups called Prides that can consist of humans and their own. Prides tend to range from 5-12 members. Now most Prides tend to be made up of Hybrida, but well trusted and loved humans can join their ranks, though it is rare, due to being isolated from public cliques.
Culturally, the Hybrida are well respected, even though they are avoided out of fear and lack of understanding. Hybrida also speak two languages, English and Latin. But what sets them apart, is how most speak in an archaic form of English around humans, while amongst their own, they speak latin to keep conversations private and confuse the hell out of humans that don't speak the near dead language.
Hybrida have been known to be vengeful towards those who betray their trust and loyalty, to the point where they will hunt you down, no matter how far across the galaxy you are, and strangle you. If a member of the Pride has been betrayed, the whole pride takes part in the hunt, and by law are allowed to kill traitors.
Ex: A human general that is a part of a Pride betrays a member (Brother or sister), then the whole pride is allowed to kill him, no matter the rank.
Those who betray their mate, have signed a death warrant. The Hybrida will go into a blind rage and hunt down the traitor, killing any who get in their path. That is when a Hybrida is most dangerous, for the only way to stop them is to either let them kill their ex, or several bullets to the head. The Former is usually the preferred choice , cause shooting them only makes matters worse.
Hybrida that are not born within a Pride are usually called untouchables, Prideless, and Misborns. They are typically avoided by others, and very few get to join Prides, unless in military service, where they form their own most of the time, but there are still outcasts among the ranks. They are looked down upon by others of their species, and 25% commit suicide at the age of 15.
Those that don't kill themselves, tend to have stronger bonds of friendship and loyalty when they are accepted into a Pride or create one. This comes to an advantage on the battlefield, as seeing their loved ones and friends under attack cause them to fight harder and not break moral. Most of the time they become commando units in the armed forces if they are an effective group as well.
Psudohybrida: The taboo offspring of a human and True Hybrida. Although rare due to social views, They are some of the more beautiful of the two races.
Psudohybrida, commonly known as half-breeds, take on both their parents traits. They're typically a couple of inches shorter than the average Hybrida, and are stronger due to their human genes. Like their hybrida parent, they share the same features but the eyes; while Hybrida have no visible pupils, Half-breeds do due to their human genes. due to being half human, they are not as adaptable as their Hybrida parent
Depending on their upbringing, Very similar to the typical hybrida/human
