A modern day world where alien bio-armored warriors defeated monstrous beings that unleashed destruction upon Earth in retaliation
Type: BudAlthough this Earth is dead, it is possible that There could be other Survivors. When Archanfel had been killed at the end of the ward there were 22 Guyvers in total active.
Guyver I AKA Sho Fukamachi
Guyver II AKA Oswald A. Lisker (destroyed)
Guyver III AKA Agito Makishima
Guyver IV AKA David Jackson.
This Leaves Guyvers 5 - 24 Open for OC characters. The unit would have been handed out from David. But all are activite and may have been pulled into the Metaverse in different locations and different times.
David Jackson found 21 Guyver units in the Relic ship of North Dakota, and after Chronos had taken over the Earth he had handed out 19 of the remaining units to various people to fight the Zoalords and Chronos. So it is possible that Other Guyvers survived, allowing someone to app Either Sho or Agito, or an OC Guyver. Though David made sure to hand out the units to people who knew who truly hated and lost a lot to Chronos.
It is also possible that some of the Zoanoids/Hyperzoanoids may have survived and escaped like David, and could be antagonists.
Millions of years ago, Aliens known as the Ouranus arrived on Earth and after discovering it's planetary evolution was only just beginning, they claimed the planet and began the process of Manipulating the planets Bio-Sphere and natural evolution to produce one thing. The Ultimate living weapons. Twice in the history of the Earth, they caused mass extinction events. All because they were not happy with the results of their creations.
With the Rise of Mammals, they looked upon their creations with favor at long last. Millions of more years one stood out above all else. A species rose from primates.,Homo Sapiens.
Taking about half of these primitive humans they bioengineered them to be able to assume a powerful set battle form. And thus the first Zoanoids were born. Then taking some human DNA as the Base they made him; Archanfel, The One True Zoalord, to be their great general of this endless army. And Archanfel looked upon the advents with love, affection, they were his parents, his gods!
Through all these experiments The Advents were happy, but a question was poised, One experiment remained. How would an unprocessed Human respond to one of their Bio booster suits?
The Result was DISASTER!
The Bio booster, designed to adapt, conform, enhance and maximize the genetic potential of the host produced a creature that was beyond even the Zoanoids. But when they ordered the Human to remove the armor, he turned on the Ouranus. All Ouranus Creatures had the genetic coding that made them obedient to their master's telepathic powers. The Bio-booster Not only deleted that genetic code but also had developed a Psychic shield that blocks all telepathy from reaching the host.
This they named. GUYVER: OUT OF CONTROL
They dispatched the Zoanoid army, Guyver 0 slaughtered his way through them. After much pleading from Archanfel, He was finally dispatched with a Unit Remover to destroy the Guyver. And so he did. But fear had Gripped the Advents. If one of their bio-boosters had transformed an unprocessed human into a Killing machine that they could not control why enhancing his abilities to such a degree. What would happen if A zoanoid or worse Archanfel was bonded to a Bio-Booster and Became Guyver?
The sheer level of power he might have was beyond their ability to predict or comprehend. Panic ripped through the Ouranus. On mass in a rush to get away they boarded their ships and fled, leaving some behind. Archanfel attempted to follow them and despite being ordered to remain on the planet through sheer force of will broke The Ouranus control over him to follow. They attacked Archanfel Psychically Crippling him. Maybe even fatally wounding him.
As they fled they sent a Mars-sized Planetoid on an impact course with earth. To utterly destroy their creations. Archanfel betrayed and hurt, refused to let Earth be Destroyed. Even crippled as he was erected a Psychic shield around the planet, and obliterated the planetoid at great cost to him. Wounded, drained Archanfel returned to his island and the chamber that gave birth to him to hibernate and recover.
Eventually, Archanfel would awaken when a human Hamilcar Barcas arrived on his island and transform Hamilcar into the first of 11 Zoalords to take over the planet. And thus Chronos was born and for 400 years they began working to make more Zoanoids, and take over the planet. Eventually, in Japan, three bio-boosters were recovered and lost.
But the Guyver units of Japan were not the only Guyvers left behind, nor was the vessels in Arizona or Relic Point. There were others.
After many years the Guyvers succeeded in Destroying Archanfel, and the remaining Zoalords. With their Loss of control, they chose to sterilizes the earth and made sure a contingency plan ensured the Guyvers would fail no matter what. And when the Heroes were needed most... they Failed. Leaving only one known Guyver alive to watch the world descend into chaos and burning hellfire.
