A member of the reformed Band of the Hawk, and an exceedingly strong apostle. He is a giant, red-haired man in scale plate armour that resembles a dragon. Armed with a warhammer and a cannon hidden in his shield, he is renowned as a famous war veteran in the northern part of the continent. He had apparently held ground against a superior, overwhelming force of three thousand from Chudor, lasting for months on end. He fought Guts at Flora's manor; easily defeating his already weakened body. Later, after Guts' acquisition of the Berserker Armor, he was forced to reveal his true Apostle form. In his apostle form Grunbeld is a quadruped dragon whose outer shell is composed of stylized corundum crystal formations harder than steel and is able to exhale flames from his mouth.
