Brett Thompson is an Osean interviewer working for the Osean Broadcasting Corporation, like Albert Gennette. He is most famous for his role as a narrator of the events of Ace Combat Zero alongside the Belkan War veteran Larry Foulke. He (Brett) wanted to learn the true meaning of war and why the Belkans had spread among the world. So he began traveling across the planet, and found out information from the legendary mercenary squadron, Galm. He interviewed many former pilots of the Belkan War & ex-members of A World With No Boundaries, the Belkan Air Force, UAF, Sapin Air Force, the OADF, and the YAF. He traveled to different countries and cities like Oured, Cinigrad, Jackson Hill, Gran Rugido, Holtz, Dinsmark, and Delarus to find information.
