Zangetsu appears as a tall lean-built, and stoic middle-aged man. He has pale skin, high cheekbones, stubble, and long ragged black hair with brown highlights. His attire consists of a tattered white dress shirt with an upturned collar and cuffs, black pants, low-heeled boots, and a long, amorphous black overcoat with a burgundy highlight that flares out into ragged ends. He wears brown-tinted, semi-transparent wraparound sunglasses.
