Galliard was a young man of average height. He had hazel eyes, and his blond hair was kept in an undercut style which was pushed back. He wore combat trousers and a short coat. He also wore the Eldian armband on his left arm, as required of all Eldians under the authority of Marley. While undercover on Paradis Island, Galliard stole a Scout Regiment uniform to disguise himself as part of the Jaegerists.
