Gilbert G.P. Guilford was known for his slender physique, dark hair, glasses, and role as the Spearhead of the Empire's personal knight to Princess Cornelia. He commanded her Glaston Knights and initially flew a Gloucester before switching to the Vincent model in the second season. After informing Jeremiah Gottwald about his demotion, he helped end the Black Rebellion with the assistance of the Glaston Knights. Following Princess Cornelias disappearance during the rebellion, Guilford remained in Area 11, waiting for her return. In the absence of Viceroy Carares, Guilford served as a temporary replacement before Nunnally assumed the position.
