|Family|| Shannon Adama, wife|
Tamara Adama, daughter
William Adama, son
Sam Adama, brother
His wife Shannon Adama and daughter, Tamara Adama were killed in the MAGLEV bombing. He lives in an apartment at 615 Olympic St in Caprica City with his surviving son, William Adama and his mother in law, Ruth.
Born on Tauron
The Ha'la'tha funded Joseph's education in law. He often helps defend agents of the Ha'la'tha against criminal charges. At the beginning of the series, Joseph's last name was Adams, but after his wife and daughter's deaths, he changed it back to Adama.
Joseph is inexperienced in V-World. Daniel Graystone introduced Joseph to V-World to prove that a recreated Tamara existed in V-World. Joseph immediately rejects Tamara as a fake, but he is crushed when Daniel tells him that Tamara's avatar has disappeared. Joseph buys a holoband in order to conduct a search for Tamara online.
Joseph wants what's best for William. Although he works for the Ha'la'tha, he stays away from the darker aspects of the organization. He's reluctant to kill anyone, even in V-World, but he does have a breaking point, where he will murder several V-World guests to get what he wants. Even during this incident, he gives the other guests a chance to leave Ghosts in the Machine.
Joseph is also fairly naive, which frustrates a number of other characters.
