Pieter Hale is a man in his early thirties, with blond hair, blue eyes and a slight Russian accent. He wears glasses not because he needs them, but because he thinks it's something academics should wear. If his hair is not kept cropped short, it quickly grows out of control and seemingly takes on a life of its own, defying combs and styling gel to maintain a naturally frazzled look. As such, Pieter often looks like he's been working with unsafe electrical equipment. Under his shirt, he has distinctive birthmarks across his chest and back, though he rarely reveals them.
