Laguna Loire is a man whose past and relation to the main characters are revealed slowly throughout the game. Most of the sequences involving Laguna appear in the form of "dreams" experienced by the primary protagonists. Squall always experiences these dreams from Laguna's point of view, although he does not think too highly of Laguna.Laguna attacks with a Machine gun and his Limit Break is Desperado, which involves a swinging rope, a grenade, and a barrage of bullets. During the dream segments, he is a twenty-seven-year-old soldier in the Galbadian army who travels with his companions, Kiros Seagill and Ward Zabac. He is also an aspiring journalist.
