The Xenomorphs are an extraterrestrial race who's origins have yet to be explained. However, what is known is that they managed to land on our world when a ship full of them crashed on our world. It's been discovered that the ship carried a Queen and her offspring as they crashed onto said planet who were being experimented on by the Weyland-Yutai corporation but the Xenomorphs broke out and killed everyone on board.

After the crash, the demonic energy turned them all into monster girls who function differently from what they once were. Most Xenomorphs live in hives which are usually almost always found in subterranean locations, though said hives can be anywhere in the world.

The normal life cycle of Xenomorphs involves being born from their hosts through Facehuggers injecting the egg of the Chestbuster into the host. Later on, the Chestbuster comes out through the chest of the host, which is fatal. These chestbusters later grow up into the many different types of Xenomorphs like drones or queens.

However, the exposure to demonic energy has greatly changed the way the Xenomorphs' lifecycle works.

Xenomorphs can only give birth to more of their kind when their husbands' seed is mixed with a special seed that facehuggers lay. Otherwise, they'll only give birth to facehuggers, and the queen is much more fertile than any other Xenomorph, with the other breeds having been believed to be infertile for a long time due to just how low their birthrate is.

The new Xenomorph reproduction cycle goes as follows. When a facehugger is created, she will happily seek the husband of a Xenomorph and cling to their faces, having the husband lick her pussy until she cums. The special seed is contained in their pussy juice, which the husband will inevitably swallow as the facehugger is clinging to his head. This special seed enters the bloodstream through digestion, eventually making its way to the men's testicles. When said husband cums into a Xenomorph or a Queen, this allows him to impregnate his wife with and give birth to a newborn Xenomorph.

The Xenomorphs are a hive race and they are usually ruled by a Queen for each of their hives. However, these Queens can evolve into an Empress who can command several queens. But these Empresses bow down to a Hive Mother which usually evolves after a hive becomes big enough to rule over a large part of an entire continent. The Hive Mothers, Queens, and Empresses all have a psychic link with the other Xenomorphs which allows for them to communicate telepathically with those below them and between them.

Xenomorphs are always known for their rather aggressive nature, however, some are capable of advanced thought, but none more so than their queens and further evolutions. They do seek husbands and tend to try to avoid other mamanos…but they always have a rivalry with another extraterrestrial race which is the Yaujta (AKA Predators) as they usually engage each other when trying to find a husband.

Xenomorphs have a wide variety of personality traits depending on their host, though they are usually known for being aggressive and very protective of their husbands and hive monarchs.

However, due to the Demon Lord's desire for non-violence among mamanos, the rivalry between the Yaujta and Xenomorphs is much less lethal than in the past. Though it has been noted both parties have known to cooperate with the mamanos on our world to deal with the Order after learning that organization has begun to use Argent Energy which might cause problems for both of their own societies since the Order and their members have begun to kill their own in combat. And many Hive Monarchs, none more so than the Hive Mother ruling the other Xenomorphs in our world, who claim to have "discovered the truth" have become extra aggressive towards the Order.

A typical xenomorph usually appears to have a black carapace-like skin, a domed head, sharp claws, tail, feet, and black smokestacks-looking growths on their backs. Those that reach physical maturity tend to be very tall and well-endowed.

Xenomorphs also have different abilities depending on which hosts they are birthed from. However, all Xenomorphs all have a highly corrosive acid for blood which is capable of instantly melting the toughest of flesh with ease but can't melt the Xenomorph's own carapace.

There are many types of Xenomorph mamanos and below are the most known Xenomorphs:

Hive Mother

Empress

Queen

Drone (also known as Warrior)

Praetorian

Facehugger

A Nameless Scholar's Notes: It's worth noting that the one ruling and commanding the Xenomorphs on this planet is the Hive Mother which she confirmed to be the same Xenomorph Queen who crash-landed on the planet by accident. Though it makes me wonder how many more hives are out there, holding Xenomorph queens that haven't revealed themselves.

A/n: So yes, it was a long time coming but now we have the Xenomorphs. Which are very interesting as a race to incorporate into the setting of FMGE but I have FINALLY done it.
