"Big Boy" Berk is a stubble-chinned, dark haired ratling with stained-glass style tattoos down his right arm of Imperial saints in sharp colors and a belt of bullets tattooed on his left forearm, each marked with the name of one of his cousins in the Guard.  He keeps a confident grin on his face even in the worst weather, and claims he's only a virgin because his family's secret recipe is tattooed on his junk and any girl who sees it has to marry him.
