Number Six is a seductive, statuesque Cylon infiltrator. Most, but not all, versions of Six have platinum-blonde hair. She was the first example shown of a new generation of Cylons capable of adapting to human form and emotions. Little else is known of her earlier years. She can, like other Cylons, retain memories and be downloaded into another body if the original body is killed. Like her counterparts, her body was designed to mimic the human body at the cellular level, making her almost undetectable to testing procedures, and there are many copies of her in existence.
