Dr. Gaius Baltar

Scientific genius and moral weakling, Gaius Baltar is constantly torn between self-interest and guilt as he climbs his way up the political ladder to become President of the Twelve Colonies—then falls down into the hands of the Cylons—and later becomes the leader of a monotheistic cult. All the while, he carries on an unusual, clandestine relationship with the Cylon Caprica Six.
