The Yautja were in a global tribal war for aeons with all the Clans fighting for world supremacy and each having to quickly engineer new methods of attack and defense. As part of this war they developed the Xenomorph species which have since  spread throughout the galaxy. They often travel to planets infested with the Xenomorphs as part of a great hunt.

Species Name: Yautja

Type: Amphipod Humanoid

Physical Traits: Yautja have great height, arthropod-like mandibles and long, hair-like appendages on their heads. Their bodies are resilient to damage, capable of recovering from multiple gunshot wounds and radiation doses which would be fatal to humans. They are much stronger than humans, having been portrayed as being easily capable of outmatching a conditioned adult human male and shattering solid concrete with their bare hands. They are also skilled climbers and will readily move through trees or across rooftops in pursuit of prey. Though capable of surviving exposed in Antarctic temperatures for an extended period of time the Predators have a preference for hot equatorial climates. Their blood is luminescent phosphor green in colour. Their vision operates mainly in the infrared portion of the electromagnetic spectrum; they can easily detect heat differentials in their surroundings but are unable to easily distinguish among objects of the same relative temperature. They are capable of breathing Earth's atmosphere.

Females being larger and stronger than males and sporting more prominent mammary glands like human females. Both genders give off a strong musk to signify aggression while females can also emit it when in estrus. This musk can be detected by other Yautja and canids though it is imperceptible to humans. They are not monogamous and it is not uncommon for veteran warriors to sire hundreds of offspring (known as sucklings) with multiple mates. Their blood has the capacity of partially neutralizing the acidity of Xenomorph blood.

Yautja possess a gland located between their neck and collarbone which secretes powerful hormones into their bloodstream and which drives them to hyper-aggression. When this gland is over stimulated it sends the creatures into a frenzied rage, causing them to attempt killing any living thing in sight including members of their own species. This "kill rage" can be contagious and spread from one to another driving them all to attack each other. The Yautja species barely survived the wars provoked by their kill glands and they have learned to control the gland's secretions with artificial hormone regulators.

Technology: 9, Yautja technology is unique in many aspects not in the least due to its ornate, tribal appearance masking deadly, sophisticated weaponry. Many weapons use a metal that does not correspond to any element on the periodic table and some weapons have been shown to be completely resistant to the effects of acidic blood belonging to Aliens. Their mask increases their ability to see in a variety of spectrums, ranging from the low infrared to the high ultraviolet, and also filters the ambient heat from the area, allowing them to see things with greater clarity and detail. They also makes use of a light-bending cloaking device.

Culture: Hostile, intolerant and aggressive but held in check by strong social customs. Yautja culture revolves around the hunting and stalking of dangerous lifeforms. After making a kill they typically skin or decapitate the carcass converting it into a trophy. Failure in a hunt results in the Predator involved committing an honourable suicide. The hunt is not for sustenance or elimination of threats but as entertainment as they will only attack life forms that have the ability to provide them with a challenge. Yautja live by their Honour Codes - not hunting unarmed prey, sparing or ignoring the frail and young, prohibited the use of the cloaking device while hunting, and so on. These rules come with severe punishments if broken by their individual Clan.

A caste hierarchy exists with treatment of an individual is determined by their social position with the stronger and most skilled of the group being leader. Their religion is polytheistic, and that their equivalent of the Grim Reaper is the so called "Black Warrior", who is seen as an eternal adversary who eventually wins all battles.
