The Cylon Occupational Authority is a group of Cylons assigned to govern over the rule of occupied New Caprica. While officially they are present only as "allies and friends of the legitimate Colonial government", they are in reality in complete control of the planet. The occupational authority attempts to rule by consensus, but as a copy of Number Three notes, the strains of occupation make consensus more difficult to come by.
Only seven of the twelve Cylon models have been sighted on New Caprica:
- Number Three—At least one copy of Number Three appears to be posted to the planet—the same copy that knew Caprica-Six and Sharon Valerii (Galactica copy) on Caprica. Three's role is largely supervisory, although she also begins a path of spiritual discovery on the planet that leads her to question her faith and discover that Hera, the child of Karl and Sharon Agathon still lives.
- Number Five—At least two copies of Number Five are present on New Caprica. These copies are at times violent towards humans, supervising the temple massacre, shooting Caprica-Six, threatening Baltar at gunpoint, and suggesting that if the occupation fails, they could simply nuke the New Caprica settlements. At other times, the Fives seem optimistic about the possibility of lasting peace, convincing Jammer about the potential of both peoples working in harmony, and discussing with Gaius Baltar how small things, like the presence of sufficient toilet paper, would help to quell human unhappiness.
- Number Six—At least three copies of Number Six are assigned to the occupation, including Caprica-Six. Caprica-Six has a different perspective than even other copies of her name model, and is present largely to rejoin the company of her beloved Gaius Baltar. She, along with Sharon Valerii (Galactica copy) is most optimistic about the possibility of lasting peace, and is reluctant to adopt stern measures.
- Number Eight—Sharon Valerii (Galactica copy) is present on New Caprica, as are possibly other copies of her model. Valerii seems to share in Caprica-Six's mission.
- Brother Cavil—At least two copies of Cavil are present, to the apparent chagrin of the other models—Cavil often mocks their faith and makes outrageous, potentially sarcastic suggestions, such as executing Baltar. Copies of Cavil also free Saul Tigh from custody, and Tigh's wife, Ellen, performing sexual favors upon another copy of Cavil in exchange for her husband's freedom. Cavil also supervises the attempted executions in Precipice—after being left to die when the New Caprica Resistance frees the prisoners, this copy at least decides that the occupation is no longer worth it.
- Simon—Simon is only sighted once, voting with the others to agree on executing suspected members of the insurgency.
- Leoben Conoy—Only one copy of Conoy has been sighted. He is the captor of Kara Thrace and the supposed father of Kacey, another hybrid child created from Thrace's ovary. He attempts to force Kara to live a married life with him—however, she kills him and forces him to download at least five times before finally appearing to give in. Conoy, interestingly, does not seem to be part of the Occupational Authority per se—for instance, he is not present when the authority discusses or votes upon their plan of action.
