Cylon

The Cylon are a race of serpentine organisms whom created by the now-masterless Cylon, from the planet Cylon. They went extinct hundreds of years before mankind ever encountered their deadly creations. They discovered [[Wikipedia:Earth|Earth - as many species before them had - and upon seeing the ancestors of man, decided it to be a perfect form; this is why their robotic creations are bipedal when they themselves were not.
