Sukuna is a tall and muscular man with four arms, four eyes, and a large mouth on his stomach. He has short pink-red hair and red eyes, with his two right eyes being angled differently and located on a white flesh plate-like structure on the right side of his face. However, despite his brutish, bloodthirsty, and dismissive attitude, Sukuna is actually incredibly intelligent, perceptive, and cunning. Sukuna is known for being stubborn and troublemaking, as well as careless with his own life.
