Megumi is a relatively tall and slim young man with fair skin and green eyes (dark blue eyes in the anime adaptation) that slant upwards to denote his harsher and colder personality. He has uniquely styled black hair with long spikes that jut out in every direction around his head, resembling a sea urchin (according to Hakari). When first meeting Megumi, Gojo noted the resemblance to his father Toji Fushiguro and Megumi himself has similar facial features and green eyes.
