D'Anna Biers (Number Three) is a fictional character from the re-imagined Battlestar Galactica television series, played by Lucy Lawless.

Three first appeared in the episode "Final Cut" as D'Anna Biers, a reporter for the Fleet News Service. In this episode, she is given full access to Galactica by Commander Adama to film a documentary about the military. During filming, D'Anna comes across the Cylon prisoner Sharon "Athena" Agathon and discovers she is pregnant when Dr. Cottle rushes to save her baby from miscarriage. D'Anna is ordered to remove the evidence by Adama on the grounds it could jeopardize fleet security. The episode concludes with a group of Cylons watching the documentary as well as the removed footage—it is in this scene that D'Anna's identity as a Cylon is first revealed.

"The duality of my role is very fun to play as an actor because she is saying one thing, she looks like a friend, but there is something cold about her. I’ve been reading a book called The Fantastic Bond and it talks about cold mothers who may have physical proximity but no warmth towards their child. There is something about that which is one of the most malignant types of mother love there is. I kind of wanted an element of that in this woman, which is why on some level she is really creepy."

"She was a zealot, she was an outlaw, she was a betrayer and yet she saw herself as a great patriot in a way."

In the episode "Downloaded", D'Anna debriefs newly resurrected Caprica Six and Sharon "Boomer" Valerii and helps them to integrate back into Cylon society. When the two begin to show sympathy towards the humans, D'Anna reacts with disgust. Ultimately she is killed by Caprica Six to protect Anders, a resistance fighter. After D'Anna has resurrected (offscreen), she claims this to be the first act of Cylon-on-Cylon violence in their history. Ironically, Caprica actually averted Three's own unwitting act of Cylon-on-Cylon violence, patricide in fact, as Anders is later revealed to be one of the Final Five, the creators of D'Anna and all other Humanoid Cylons. Three is also unaware of Boomer destroying a Basestar filled with copies of herself, as well as Athena gunning down on two separate occasions a Number Six and a Number Eight who threatened Karl "Helo" Agathon on Caprica.
