Galliard had the appearance of a young man of medium height and slender complexion. He had gray eyes, and his blond hair was 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. He also had somewhat of a bitter personality, and was shown to treat others condescendingly. He seemed to be prone to using passive aggressive speech, with a few exceptions.
