Fives are played by Matthew Bennett. Number Six (Caprica-Six / Shelly Godfrey / Gina Inviere / Natalie Faust / Lida / Sonja) The first model explicitly revealed to be a Cylon in the mini-series, Sixes often use seduction to their advantage. Important copies include Shelly Godfrey, Gina Inviere, Head Six, Caprica Six and Natalie. Caprica Six The first Cylon seen, Caprica Six had a two-year relationship with Baltar on Caprica, during which she used him to gain access and plant the backdoors in Colonial military network software which enable the total success of the initial Cylon attack. She sacrifices her body to save Baltar's life from a blast wave of that Cylon attack. She then exists for the rest of the series in Baltar's imagination as his "Inner Six," in addition to returning in corporeal form which is then known by the nickname "Caprica Six." Caprica Six has a love-hate relationship with Baltar, alternately defending him to other Cylon models or leaving him to suffer at their hands. A reincarnation of Caprica Six commits the first incident of Cylon-on-Cylon violence, killing a Three with a rock to save Anders's life. Caprica Six was imprisoned on Galactica after helping Athena escape from the Cylons with Hera. She offers to testify against Baltar. While in the brig, she has a relationship with Saul Tigh. This results in the first Cylon-Cylon pregnancy in 2,000 years, which ends in a miscarriage. Caprica Six has an "Inner Baltar" which only she sees, similar to how Baltar has an "Inner Six" that only he can see; Inner Baltar serves as a sort of conscience for Caprica Six and as an advisor in times of trouble, as Inner Six does for him. Inner Baltar appears at least once to Baltar himself. Before their true nature is revealed, speculation rises that Baltar is a Cylon. Inner Baltar and Inner Six appear to Baltar and Caprica Six – all four sharing a moment together – as the first part of the revelation that the "Inners" are divine beings (referred to as "Angels") manipulating both the Colonials and Cylons into fulfilling "God's plan" (series finale). Shelly Godfrey Godfrey was on Galactica after the Cylon attack. She accused Baltar of treasonously sabotaging human defenses, and therefore of killing several million people (Six Degrees of Separation). She also appears in Battlestar Galactica: The Plan TV movie.
