Sig Curtis

The husband of Izumi Curtis, an enormous muscular man who works as a butcher in the town of Dublith. He is a man of few words and does not question the judgment of his beloved wife, even after she tried to resurrect their infant son when the child died. Like Izumi, he cares deeply for the Elric brothers and also dislikes the military. In the manga, when greeted by Fuhrer King Bradley, he ignores the Fuhrer's inquiries and offer for Izumi to become a State Alchemist, but ends up befriending Major Alex Louis Armstrong in a muscle flexing contest. Strangely, in one episode of the anime, he is seen sleeping with both eyes open.
He also becomes friends with Winry Rockbell.
