(The reimagined series; Caprica and Blood & Chrome)
The Cylons are a race of sentient machines and synthetic organic beings. Their racial nomen and shared characteristics stem from the "Cybernetic Lifeform Node", which was developed by Zoe Graystone. Due to the revolutionary advancement in computer technology Cylons represented, they became widespread over the following decade. They later rebelled against mankind to free themselves of slavery, unleashing a twelve-year genocidal conflict where the total annihilation of the adversary's race was the only chance for continued existence. After the signing of an armistice, the Cylons left the Twelve Colonies of Kobol for a world of their own, dubbed The Colony, where they continued to evolve their designs. Of the fortieth anniversary of the armistice, the Cylons broke the armistice and began a massive-scale offensive within the colonies, killing tens of billions within days. Over the next four years of harassing a human refugee convoy, the Cylons began to develop competing ideologies, which led to a civil war. The only known Cylon survivors of the conflict were a group of sentient Centurions on a rebel Basestar, and Humanoid Cylon colonists on a planet named Earth in honour of a lost colony.
The Cylons themselves are part of a wider cycle of creation and destruction, and other sentient machines were developed independently on Kobol and the original Earth, which are also known as "Cylons" by Colonial humans but for convenience are place on a separate page (see: "Thirteenth Tribe" and "Earth Centurion").
The Cylons were developed from two separate concepts by Daniel Graystone and his daughter, Zoe. Daniel's company was under contract by Caprica's military to mass-produce a series of sophisticated robots which could assess a combat situation and plan countermeasures to new situations, something which at the time had never been done. The U-87 prototype was made functional thanks to the installation of Zoe's AI creation and was, eventually, copied into the bodies of thousands of robots, from military robots like the Centurions, to construction robots, to domestic service robots. The sophistication of the AI, based directly on her brain, resulted in thousands of sentient robots effectively living as slaves.
Eventually these Cylons began a general insurrection against the humans and ushered in a years-long long war against the Colonial military, constantly developing new weapons and technology to stay one step above the humans. After twelve years, the Cylons were contacted by a group of five humanoid Cylons who came from Earth, a planet which was destroyed when their own mechanical Cylons rebelled against them. The Cylons agreed to their plea to end the war, in exchange for humanoid body manufacturing and resurrection technlogy.
In the next forty years, the Humanoid Cylons gained control of their emerging civilisation, with the Number Ones exiling their creators, later dubbed the "Final Five". Afraid of a Centurion revolt as befell the people of Earth, it was voted by representatives of the Seven models that chips be installed to prevent them thinking for themselves, thereby becoming slaves.
After forty years of isolation, the Cylons began a massive assault on the Cyrannus star system, wiping out all human colonies there, and killing tens of billions within several hours. For the next year the Cylons conducted a search for survivors to ensure total eradication, but a revolution spearheaded by "Boomer" and "Caprica Six" led to the operation officially ending. A year later the Cylons made an attempt to co-exist with the humans on the newly-established New Caprica colony, but this failed due to the more fanatical models ensuring its failure through excessively violent responses to a resistance movement.
Following the abandoning of New Caprica, the Cylons began a mission to search for Earth, and interchanged between negotiating a truce with the humans and preparing ambushes to eradicate them. Unrest among the Humanoid Cylons continued, resulting in the entire line of Number Threes being boxed, and new bodies prevented from growing. The Twos, Sixes and Eights launched a general insurrection against the other Cylons in response to the Ones' dictatorial actions, and most of them were wiped out. A damaged Baseship crewed by them allied with the Battlestar Galactica, and the repaired ship, with human assistance, was able to destroy the Resurrection Hub, ending the immortality of all Humanoid Cylons.
Cylon types Edit
Cylons developed into a variety of forms during their evolution. Prior to the Cylon War, Cylons were typically of a humanoid design to allow functions ranging from domestic servants, to construction crews, to soldiers. The military Cylons were known as "Centurions", and at the time of the Cylon War, Model 0005 was the latest build. During the late stages of the war, the Cylons made attempts to evolve into cybernetic organisms, in research that required the amputation of live specimens. This research was ultimately successful, with the creation of the first Hybrid, a Cylon with an organic body, that could be used to interpret computer data and operate a basestar. Following the war's conclusion, the Cylons worked with the humanoid Kobol Cylons to mass-produce new organic Cylons, Hybrids amongst them. The mechanical Raiders of the Cylon War era were replaced with the new 'Raider' and 'Heavy Raider' designs, with the former as a lifeform within a metal case and the latter as a machine used as a troop carrier. New Basestars were constructed with biological material that would grow and harden like bone, allowing ships to repair themselves if damaged. Despite the general push for biomechanical creations, by the Fall of the Twelve Colonies mechanical Centurions were the mainstay of the Cylon ground forces.
