development of the Cylons by humans on the Twelve Colonies. The initial physical form developed was a Graystone Industries U-87 drone soldier, with a revolutionary new MCP ("Meta-Cognitive Processor"). This formed the foundation for other Cylon technologies incorporated throughout the Twelve Colonies. Cylons were originally accepted into Caprican culture as robotic workers after a group of them (under direct remote control by Graystone himself) successfully thwarted an attack on the public at Atlas Stadium by the terrorist group Soldiers of the One (STO). Battlestar Galactica Battlestar Galactica takes place roughly 40 years after the end of the first Cylon war, fought between the end of the Caprica prequel and the start of the re-imagined series. In the war, both sides fought to a standstill until the Cylons agreed to an armistice and promptly disappeared; in the interim, they improved their technology and heavily militarized with the intent of conducting a first strike surprise attack against the Colonies. Cylon models and technology BSGr Cylon society consists of several classes differentiated by function and form. Cylon "Centurions" are the fully mechanical core of Cylon culture, developed and evolved from the first laborers and proxy soldiers designed during the events of Caprica. During the armistice, the Centurions met the "Final Five" Cylons, a group of evolved, biological descendants of the Thirteenth tribe of Kobol (hitherto thought of as a myth), who offered to help them develop their own biological models and resurrection technology. In turn, during the forty year armistice they developed eight additional Cylon biological models, as well as partly biological/partly mechanical Cylon Raiders, improved Basestars, and lastly, the complex Cylon Hybrids which exist in symbiosis with the Basestar. The biological models have (at times) demonstrated enhanced strength, stamina, and an ability to interface with computer systems; however, they also feel pain, hunger, and fear. Cylon biological technology has also shown weaknesses to radiation and disease as some of their few vulnerabilities. Consciousness All Cylons in the re-imagined series use a digital consciousness employed in mechanical or biological mediums; the primary capability this allows is the ability to "download" or "resurrect" into a new body. Because of this, it is possible for some Cylons to share memories, have their memories repressed as Sleeper agents, or have their personalities modified. Because of this ability, Cylons use the confinement of an individual or an entire line in cold storage as a form of capital
