Guy, also known as Gus, is a main character, and one of Firion's two permanent allies in Final Fantasy II, the other being Maria. Guy has the ability to talk to/understand beavers. He is a friend of the other party members, especially with Firion, but his past is mysterious, especially his ability to speak to animals and beasts. However, his backstory is expanded in the game's novelization Final Fantasy II Muma no Meikyū, which reveals Guy was raised by monsters, and thus is able to speak their language. Guy's ability is more important in the novel, where Ricard's omission means Guy acts as the translator between the Wyvern and the party. Since his lack of social skills make him a silent character, Guy takes a very small role in the plot.
