Tamara Adama Tamara (portrayed by
Genevieve Buechner) is the teenaged daughter of Joseph and Shannon. She is among those killed in the train bombing portrayed in the
Caprica pilot. After her death, Daniel Graystone uses a computer program written by his daughter Zoe to create Tamara's virtual avatar, Tamara-A, who later finds her way into the V-Club. Tamara-A is initially unaware that the real Tamara has died, and believes that she is the real Tamara and just needs to be woken up. A gamer named Vesta eventually breaks the news to the devastated girl. Tamara-A shoots Vesta and asks Heracles to find her father and tell him that she still exists in the V world. Learning that his daughter Tamara is still alive as an avatar, Joseph attempts to seek her out in V-World no matter what, even if it means ignoring his responsibilities as a father to William and refusing to move on with his life after granting Tamara's soul passage to the afterlife. Realizing her full potential and invulnerability against all odds, Tamara becomes an influential icon in New Cap City stirring a cult following of her undying stature. Her father Joseph becomes a player in New Cap City and discovers her initials all over the city, the same initials she used to draw when she was a child. Tamara unexpectedly receives a visit from a stranger named Emmanuelle, who is actually Evelyn in the real world, delivering the news that her father Joseph is desperately searching for her. Emmanuelle persuades Tamara to kill Joseph's avatar for the sake of his well-being, to help him finally let go of his grief. Shortly after, Joseph is at long last reunited with Tamara in her apartment. Instead of being greeted with a loving father-to-daughter moment, he is met with protest and disgrace. Tamara tries to convince her father that he is killing himself in V-World by taking virtual amp drugs, ignoring his responsibilities to her brother William, living little of his actual life, and unable to let go of the memories that was his real daughter. Tamara then shoots herself. Before she can recover from her injury, she turns the gun on Joseph and pulls the trigger, killing his avatar and banning him from V-World indefinitely. Tamara utters that she'll always love her father. Over the next three weeks, Tamara's cult status in V-World grows, eventually catching the attention of Zoe Graystone's avatar, now known as the "Dead-Walker." Zoe encounters a group of thugs on the streets of New Cap City fighting them off one-by-one with a katana sword. The gang members turn out to be followers of Tamara, each of them marked with tattoos of Tamara's 'T' initials on their foreheads. Before Zoe kills the last gang member, she tells him that she is searching for the other "Dead-Walker" that is Tamara. Zoe tracks Tamara's whereabouts to the virtual sword fighting arena, only to be ruthlessly stabbed & gunned down by both Tamara & her people. When Zoe recovers, Tamara then fights her on a one-on-one sword fighting match. Zoe gains the upper hand and defeats her in the ring. Despite her defeat, Tamara constantly blames Zoe for killing both her and her mother on the Mag-Lev Train. Zoe tries to get Tamara to understand that she had nothing to do with the bombing and that the real Zoe Graystone is dead. That no matter how many times they fight, they cannot be killed. Tamara finally lays down her contempt for Zoe and the two of them set off to use their abilities to clean up New Cap City of its decadence and corruption. It was later revealed by showrunner Kevin Murphy that Tamara eventually became the basis for the
Number Eights.
