What is a Cylon? Depends on how you view it and from what series. To our left we have our typical "Toaster" Cylon from the orginal Battlestar Galactica. To our right we have the new and improved Cylon that takes the shape of the human form. True one might look intemadating with their chrome armor and red eyes, but on the other hand, Number Five, as this model is called, doesn't seem to fearful. Cylons where created by man. The Cylons didn't like their masters so they revolted. Started and keeped in conflict with humans for years. Then they dissapeared and then one day reappeared doing battle once more. When being refered by a character they refer them as "it" or "thing" because Cylons are not alive. Because Cylons can take any human shape now, everyone is now a suspect and being disquilfied as one is extremely tough.
