The Xenomorphs were created by an ancient race (The Jockey Race) tens of thousands of years ago. They were fighting among themselves in a brutal civil war. Their technology was organic in nature and was so powerful, the death toll ran into the millions. For decades, the war never saw twilight. It seemed to go on forever...until one side got an idea.

It was an experiment to create a biomechanical weapon. It would adapt to its environment, be completely independent..and finally...it would be viscous. This creature would be a living machine with the most grotesque combination of science and nature. They created a species bent only of the art of killing. The experiment was placed on a distant world ("Alien-Proteus"). They designed the species with a hive structure to keep the infestation from running out of control. The "ant" methodology was promoted. The object: To keep the infestation under control by keeping the creatures close to their "Queen."

The experiment was a success. The creatures we know as Xenomorphs were created. The standard infiltrator mission was as follows: An egg is deposited in a populace, it impregnates, and an alien bursts out of the host and soon finds more hosts which it can convert into eggs which will also hunt down hosts to impregnate. The creature will kill anything threatening and convert the rest. Soon, the populace is destroyed and the aliens are left alone on the world or spacecraft where the infestation was released. It is assumed the Jockeys that created the Xenomorphs had a procedure to eliminate the new infection.

The Jockeys were ready to unleash their creation on their enemy. The Proteus planet was still under control. The experiment seemed safe. The mother species deposited many life forms to keep their hives intact. These life forms seemed to reproduce in large numbers. When needed, a transport would simply set down and pick up a queen, a drone, an army, or just a bunch of eggs as the mission profile specified. The weapon proved useful and the war ended quickly.

The Xenomorphs were designed to adapt to current situations but their basic morphology was not to change...it did. Before the Jockeys could stop their "children", they had evolved. One small little change, something seemingly insignificant connected to the "ant" structure but not included in the alien design Royal Jelly—the strange substance used to generate a queen. When the Jockeys discovered infested worlds where there shouldn’t be, they got worried.

Given the capability to create their own queens, the infestation could not be bottled. It soon broke out of control. The Jockeys found their experiment turning against them. They tried to find a weapon to defeat their own creation but they were already demoralized from a past war. They sent one last ship to pick up "evolved" egg samples from the Proteus planet to study...it never came back.

The Jockey race vanished. After thousands of years, without transportation, the Xenomorphs quickly overran the planets they were on, then promptly died out. They might be long lived, but after ten thousand years, even their lifespan ran out. The eggs fossilized, the bodies disintegrated and the last legacy of the alien species vanished. The ship from the proteus world crashed landed on a world far away from their Homeworld.

The technical term for the Jockey Race were the Biomechanoids. They were a synchronizing of man and machine which was the natural evolution of their growth rather than a side effect. No one can truly be aware on how alien a non-terran intelligence can be. As theorized throughout history, there is virtually nothing distinguishable between them and us. Yes, they maybe have two arms and two legs with one mouth and two eyes but that’s where it ends. Two arms and two legs makes sense as do two eyes. Everything else is foreign. They are tall when standing (12 – 17 feet tall) with extremely strong arms and legs. They have dead eyes--seeing and not seeing. Very weak in comparison. Their mouths are virtually useless to them as well. Their bodies are Sepia colored although most are found jet black, like the technology surrounding them.

Their minds operate on a totally different level, utilizing powers never before even imagined. The technology is so totally integrated into their lives. Although they are themselves organic, they seem to have the capacity to merge with their devices. In many ways, all their tools, whether a hammer or a massive spacecraft, became part of their body when they use their--their tools become extensions of their own mind. Surviving Biomechanoids exist but they have gone nomadic across the cosmos. They keep to themselves and usually wait to die. Some are actively searching for all remnants of their technology in order to eliminate it. Some want to rebuild their race from the ground up. All have either a morbid fear of a all out dying hatred for the xenomorphs they created. They are also long lived. It is quite possible the ones still roaming through the cosmos actually bore witness to their species’ own destruction. Shy. Secretive. They value no one and nothing. Very selfish. Isolationist.
