The Creators... their first and foremost trait must always be mystery. No living thing on Earth has ever seen them. Even Archanfel , perhaps the only being to ever live on Earth that they directly communicated with, knows next to nothing of them.
There is no shortage of conjecture. Some say the Creators were not one single species, but a collective of races (Archanfel was told that the delegation that inhabited Earth reported to a central authority). Some theorize the Creators were all part of a hive-mind; others, that they had no actual physical presence on Earth. Others still claim that since they would have had to be bioboosted to interact with their Creator ships , perhaps their consciousnesses were housed entirely in separate control medals, having done away with cumbersome physical bodies. Others say that they did have a physical presence, but were always shrouded and protected by bio-booster symbionts.
What is known is that they are responsible for life on Earth as it is today. Their purposes demanded a life form that could process oxygen, that reproduced fast (compared to them) and that had a versatile genetic potential. And another thing that was clear was the purpose of this creation: to produce a self-supplementing army of biological warriors.
A long time ago - how long ago, no-one knows for sure, although it was more than 250 million years - the Creators landed on Earth, recognizing its unique biochemistry, and made the entire planet their laboratory. Some accounts claim they created all life on Earth, other say they molded the existing life to their designs. All things being equal, it seems most likely that they created the first terrestrial vertebrates, as it is this group on which they have focused their efforts.
And their efforts were grand. Judging from what little knowledge can be gained from the fossil record, and the sporadic facts Arcanfel divulges, the Creators had gone through two major creation phases before entering their final one. If a biological order did not live up to their standards, they wiped it off the face of the Earth. It appears they did so twice on a global scale -at the end of the geological era humans call the Permian, when they decided the huge carnivorous amphibians and primitive reptiles were useless for their ends, and at the end of the Cretaceous, when the Dinosaurs were deemed unsuitable. The same fate would have befallen their third creation, if one stubborn individual had not intervened.
But that´s as maybe. The basic fact is that the Creators, who are also known as the Uranus (The predecessors of Chronos, as Chronos was the predecessor of Zeus), or the Advents, are responsible for the creation of mankind. Setting out with small mammals, they guided several genetic lines into different directions; sometimes favoring strength, sometimes speed, and in one occasion, intelligence. Ultimately, they created a being that combined medium size with superior intelligence and enormous genetic potential, the result of the inclusion of hundreds of millions of years of hereditary information in their DNA. And several thousands of years ago, the Creators begun the final stage of their plans, namely converting the base creature Man into the warrior being the Zoanoid. At the same time, they created one special being... ostensibly from human stock, but superior in every way to the hairy, dim-witted, ungainly primates. This fortunate individual would not only be physically and mentally superior, but would also be possessed of immense psionic powers. His Zoaform would be infinitely superior to those of the Zoanoids that the primitive humans had been turned into. He would serve as the commander of the armies that the human population of the world would be turned into. Gifted and lifted up above the rest of their creation, this being, named a Zoalord, was something of a favorite to the Creators. They spoke to him as a human might to a child.
Everything was prepared. The humans were prepared to be turned into Zoanoids en masse. The Zoalord, named Arcanfel, was prepared to serve his masters to whatever end they desired.
And then, the Creators made their final and greatest mistake, a mistake that did not only compel them to destroy their latest generation of creations, but to abandon Earth altogether. They subjected a human being to fusion with one of the bio-booster symbionts to see whether it would increase it´s innate combat abilities. It did.
The bio-boosted human initially obeyed the commands of the Creators - destroying a Zoa-processed dinosaur, a symbolic gesture more than anything else. But then, when ordered to remove the armor, something unthinkable happened. The human turned on his Creators - unleashing the might of his most potent weapon, he attacked and crippled one of their ships. Shocked beyond belief, the Creators deemed the new being accursed, an abomination: "Guyver".
Charging Archanfel with removing this threat, they outfitted him with a Unit Remover. After their Zoalord had succesfully defused the threat and destroyed the hapless host of the booster unit, they contemplated the situation for a time. They must still have been reeling, and have imagined the worst possible scenarios.
So, a while after the terrifying incident, without further ado their ships drew their roots out of the soil of the planet that had been their home for millions of years, and unceremoniously took off into outer space.
Their favorite, Archanfel, followed them, pleaded with them, begged for an explanation, and when it was given - namely that this experiment had gotten too far out of hand to continue - begged them to take him with them. They refused. He protested. They punished him.
Stricken, tormented, literally crying with the grief of being abandoned by his creators, Archanfel watched helplessly as the beings that were effectively his parents left him, vanishing through spatial warp gates. Seconds later, through another warp gate, a planetoid the size of Earth´s moon appeared on a collision course with the planet. Sent by the central authority of the Creators´ civilization, it would smash the entire world to pieces, killing all life on it - even micro-organisms. This was the last thing, the final thought the Creators devoted to their creation of millions of years.
Embittered and determined, Archanfel managed to deflect their attack and save Earth, before retreating to one of the few remaining ships, left behind because they were damaged goods. Although he no longer loved his Creators, they would never leave his mind.
No Creator, nor even any sign of them has been seen on Earth since.
