Gaius Baltar is a fictional character in the TV series Battlestar Galactica played by James Callis, a reimagining of Count Baltar from the 1978 Battlestar Galactica series. He is one of the show's primary characters.

Gaius Baltar was from the colony of Aerelon, a largely agricultural world known as the "food basket for the twelve worlds". He was born and raised on a dairy farm outside of the town of Cuffle's Breath Wash. At the age of ten, finding the Aerelon dialect (demonstrated by James Callis to be a coarse Yorkshire accent) to be detrimental to his career dreams, he trained himself to speak with a Caprica dialect (Callis' usual Received Pronunciation) in hopes one day he might be considered a citizen of one of the more respected and wealthy colonies, Caprica specifically.

At the onset of the show, he is involved in an intense sexual relationship with a beautiful 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 Colonial defense mainframe so her employers can have an advantage in future contract bidding. In exchange for his access to government mainframes she helps him design a navigation program used by Colonial warships, covertly creating backdoor in the program. When the Cylons attack, they are able to penetrate software security firewalls, disabling entire fighter squadrons outright and sabotaging vital capital-ship systems. On the day the Cylons attack humanity, she reveals she is an advanced Cylon, model Number Six (later known as Caprica Six) and she used the information given to her to shut down the Colonial defenses. Baltar manages to survive the nuclear explosion that destroys his home due to Caprica Six using her body to shield him.

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 endears 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.

Gaius Baltar has not been a contender in any CBUB matches.
