The Yautja has a Code of Honor that it expects all members of the species to adhere to on pain of not being seen as a "true Yautja" and therefore subject to being destroyed. Therefore most Yautja is molded around that code, being ruthless but honorable, except for Bad Bloods. Aggression and arrogance seem to be innate in Hunters, especially the young males.

Yautja or Predators, are humanoids physically distinguishable from humans by their greater height, the long, hair-like appendages on their heads, reptilian skin, and their faces, which feature arthropod-like mandibles and no visible nose.

Yautja height and physical appearance vary; they're typically over 7 feet tall but some can grow 8 feet or even taller. There can be short Predators who have the same height as humans, but they are ridiculed for that in the Yaujta society.

The Yautja's reptile-like skin can range in color from light to dark, be mottled or clear and appear dry or moist and clammy.

The Yautja is highly resilient to physical damage, capable of healing from multiple gunshot wounds with minimal or even no medical attention, and surviving fatal radiation doses lethal to humans. Resilient to most bacteria and viruses.

They are extremely strong, skillfully
eligible to outmatching a conditioned adult male human in unarmed combat, landing blows capable enough to shatter solid concrete. Yautja can tear a human head and spine from the body easily and some have been able to tear a human body in half with bare hands.

Their strengths extend to their lower bodies as well, making them able to jump three times their height and falling ten times their height, perfectly landing on their feet. They are skilled climbers and can survive freezing temperatures though they prefer hot climates.

THE RANKS: Normally based on an individual's hunting experience and prowess.

•Un-Blooded: The un-refined hunters of the future, Unblooded Yautja are young predators who haven't completed basic training. They are or are close to, physically mature adults. Most Unblooded, and therefore subsequent classes, are male but female hunters do exist, implying a minority of them within the hunting body.
•Young Blood: Young adult Yautja who are yet to be seen as "men" and "true hunters" in the eyes of the clanmates. These hunters are refined enough to overpower a skilled human fighter, however, their skill against a Xenomorph varies. Once they kill one, Yautja marks themselves with Xenomorph blood, completing their initiation into Adulthood.
•Blooded: These Yautja have successfully killed their first Xenomorph and given it is such a broad title, skills vary. Once a Yautja is blooded, females will begin to pay him mind and his rank could deviate into more specific ones.
•Elite: The Elites encompass the more dangerous of the Yautja race. They have the skill to take on several Xenomorphs at once, including large, dangerous castes such as Praetorians, Predaliens and even Queens. Elites seem to take on some of the more nuanced, lengthy, and taxing problems and missions. This can be assigned or self-volunteered.
•Leader: A Leader is a Yautja who has been selected or volunteers to lead and teach
•Elder: The Older, wiser members of the Yautja race. Many of them are Clan Leaders.
•Ancient: Ancients are very old Yautja, some of which are responsible for creating the laws by which the species abides. To this end, they use Enforcers to put an end to crime, both within and without the species.
•Matriarch: A Matriarch is a female counterpart to a Clan Leader. While Clan Leaders rule in off-world affairs, Matriarchs rule and command Yautja Prime and presumably any other world they inhabit. Among one of the highest titles in the species.
