Battlestar Galactica: All Human Cylon Models Ranked From Worst To Best
2. Number 3: D'Anna Biers
Appearing in the second season of the show, Lucy Lawless is absolutely fantastic as Number 3, or D'Anna Biers. She initially seems to be a harmless, if slightly invasive, reporter. She arrives in the guise of making a documentary to show to the fleet about life on board Galactica.
However, it is all a ruse and the audience is introduced to one of the most intriguing, and devious, Cylon models. She is ruthless, yet completely captivating. She quickly establishes herself as one of the models in charge, rivaling Cavill for the role of top dog.
Her line runs into a snag when she becomes increasingly obsessed with the identities of the Final Five Cylon models. She works closely with Baltar, freezing out Caprica Six in the process, finally discovering the truth in the Temple of the Five. Cavill then boxes her line.
She returns once more, proving that she is willing to do anything to achieve her ends. She takes Roslin and many others hostage, threatening to execute them unless the Cylon models in the fleet are handed over to her. She is potentially the most individualistic of all of the models, with the exception of Sharon Agathon.
Her final act is to lie down with the remains of the Thirteenth Colony. It is a sad ending for such a fantastic character, but she more than proved herself in the course of the show.
