Lt. William Adama, call-sign "Husker" (because of his rough voice) is the 21-year protagonist of the video game, the persona that the character assumes whilst playing. His father had served in the Colonial military with Magus, and had saved his life more than once. When his parents died at a young age, Adama was rasied on Caprica before joining the Academy at the age of 15. After graduating at the start of the Cylon War, he became a pilot on Magus' ship, the battlestar Galactica. Magus became a father-figure to him, and Adama fell in love with his daughter, Iphigenia.
Along with Iphi, his wingmen were Magus' son Paulus, and Lt. Garris Cain.
Cylon scrolls refer led them to believe that Adama will lead the Cylons to discover the Thirteenth Tribe; as such, he drew much interest from the Imperious Leader, Lord Erebus.
