His previous appearance is described as a demon with four arms and two faces. He currently appears similar to the host he is in, but with spiky hair and unique markings on his forehead, nose, cheeks, and torso. He also has a second pair of eyes beneath his normal eyes, which are usually closed. Sukuna also has two lines on both wrists, arms, circles on both shoulders with a dot on each, two segmented curved lines on his chest, and two lines on his stomach while possessing Yuji.
