Grog, being a goliath, is grey-skinned with tattoos all over his upper body and his bald head, weighing 645 pounds and stands at 8 feet, 7 inches tall. After having a phylactery removed from his body, a scar formed on his chest, a mark of the lingering darkness within him. After donning the Belt of Dwarvenkind, Grog has grown a thick, black beard, a feat thought to be impossible for him due to male goliaths having no body hair. After joining the Slayer's Take, Grog has the brand of the guild on his right arm.
