Sukuna's past form had four arms, two faces, and looked demonic. He initially resembled Yuji Itadori, with pink spiked hair, tattoos on his forehead, nose, cheeks, upper body, abdomen, and a second pair of eyes below his normal ones. Now, as Megumi Fushiguro's host, Sukuna has black hair resembling a sea-urchin with similar tattoos and markings on his wrists, upper arms, shoulders, chest, and stomach. He wears a light-colored kimono with black edges, a black scarf, and black shoes.
