The Cylons are a fictional race in the re-imagined Battlestar Galactica. Unlike the Cylons of the original series, they were originally created by the Twelve Colonies of Kobol as robotic workers and soldiers, but rebelled and warred against their creators, vanishing after the armistice at the end of the conflict. In the time following the conflict, they have evolved into a complex society including a variety of models, some of which are bio-mechanical humanoids, nearly indistinguishable from human beings.
