Alistair stands at six feet eight inches tall and weighs in at around 180 pounds, the majority of which is muscle weight. His body is sleek and well-toned; although he doesn't have the same musculature as Ira, he is a somewhat intimidating figure in his own right. He has long, well-kept black hair that falls to shoulder length, his somewhat curled bangs hiding a lined, worn face. Beneath his prominent brow lay a pair of hawkish grey eyes, and his face is never without a permanent halo of stubble akin to a month's unattended beard growth. He has a slight scar running from his right cheekbone to his upper lip.

He dresses in a white silk shirt with a ring collar, black waistcoat, and black frock coat. About his waist is tied a golden sash, in which is stored a sabre, three throwing knives and a pair of pistols. His pants are black trousers with a fine pleat, and his feet are adorned with thigh-high cavalry boots. On his head is a slouch hat with a large red feather plume.
