Dr. Gaius Baltar is a fictional character in the TV series Battlestar Galactica played by James Callis, a reimagining of Lord Baltar from the 1978 Battlestar Galactica series. He is one of the show's primary characters.
Personality Gaius Baltar regularly uses a well-developed acting talent to spin yarns on virtually any subject when he feels the need. He possesses a dry, cynical sense of humour but is prone to bouts of neurosis. A charismatic genius and womanizer, he is initially portrayed as a self-serving opportunist, but becomes a braver and more caring character over the course of the series, expressing regret for having been "a profoundly selfish man." Baltar is initially an atheist, but ultimately converts to the Cylons' monotheistic religion. Baltar is described as "weak", "arrogant" and "a coward" by Lee Adama while Caprica Six describes Baltar as "narcissistic, self-centered, feckless and vain." William Adama once indicated that Baltar consistently sees himself as a "victim," allowing him to escape responsibility for his guilt. Later in the series, his most profound changes begin during his adoption (against his will) as a religious figure, and he begins demonstrating increased compassion and bravery. His eventual self-awareness, love for Caprica Six, and compassion for the Agathons also motivate him to humble himself, serving in the Colonial Fleet during Hera's rescue mission and eventually choosing a quiet life as a farmer.
Character biography
Early life Gaius Baltar claims to be from the colony of Aerilon, and that at the age of ten, finding the Aerilonian dialect to be detrimental to his career dreams, he trained himself to speak the Caprican dialect in hopes of one day being considered a citizen of one of the more respected and wealthy colonies such as Caprica. He also has a very troubled relationship with his father.
The destruction of the Twelve Colonies At the onset of the show, he is involved in a sexual relationship with a blonde woman. Believing her to be working for a corporation in the defense industry, and desiring a more permanent relationship with her, he gives her access to the highly classified Colonial defense mainframe (an act of treason punishable by the death penalty) so her employers can have an advantage in future contract bidding. In exchange for his access to the government mainframe, she helps him design a navigation program used by Colonial warships, covertly creating backdoors in the program. When the Cylons attack the Twelve Colonies of Kobol, they use those backdoors to penetrate software security firewalls, disabling entire fighter squadrons outright and sabotaging vital capital-ship systems. On the day the Cylons attack humanity, the woman reveals she is an advanced Cylon, model Number Six (later known as Caprica Six), and she used the information that Baltar gave her to shut down the Colonial defenses, thus making him responsible for the Cylons' successful genocidal campaign against the Twelve Colonies. Baltar manages to survive the nuclear explosion that destroys his home due to Caprica Six using her body to shield him. As a result of the nuclear blast, Number Six is killed, and as a Cylon her memories are automatically "downloaded" during the blast to be later resurrected, as revealed in later episodes. For the duration of the series, Baltar is haunted by a version of Six only he can see. This woman toys with alternate explanations for her existence, from a Cylon chip in his brain sending signals, to an hallucination created out of guilt over the attacks, and thirdly to her being an Angel sent by God to watch over him, and Baltar finally assumes the latter following a medical checkup and rationalising that her extraordinary information to solve problems cannot simply be his own mind. Having unintentionally brought about the near-annihilation of the human species, Baltar flees Caprica when Karl Agathon gives up his place on a Raptor, feeling that his own life is less important to save than a famed scientist's. The Raptor returns to the Battlestar Galactica, where Baltar attempts to endear himself to Laura Roslin, the new President of the remnants of the Twelve Colonies, and hopes to conceal his involvement in the genocide that has taken place.
