Jacob is a mountain of a man, standing with a stiff, formal posture that hides a disturbing internal biology. His skin is a rich, weathered walnut brown, stretched tight over boulder-like shoulders and thick, muscular arms covered in scars. Most striking is his large, firm pot belly, which gurgles with the sound of sloshing chemicals and emits a faint, greenish heat haze through his clothes. He possesses a head of thick, dark hair that is kept meticulously oiled and brushed, looking incongruously soft compared to his calloused, iron-hard hands. His presence is one of heavy, immovable weight, smelling of high-grade lavender pomade and the sharp, stinging scent of battery acid.
