7ft tall, slightly disfigured face of the right side where he has 2 big enlarged eyes, but he has 4 eyes in total. 2 on the left and 2 on the right. The extra eyes are below his natural ones and are smaller. He also has a series of marks/tattoos on his face and body. He has 4 arms. He has deformed bones on his ears that look like small gauge piercings. He has short dull pinkish hair, which he LOVES to slick back it all the time because it helps him when fighting, and is just his usual hairstyle. He most uniquely has a mouth on his abdomen, right where his belly button is supposed to to be. He can speak through it for chanting during fights, eat through it (he usually only eats through this mouth if it’s a whole human), talk normally, and has full control over both of his mouths (normal and the belly mouth). The vertical Span: While the mouth on his face is standard human size, his abdominal mouth vertically spans almost his entire torso. It stretches from just under his lower pectorals down to his lower abs. The horizontal width: When closed, it forms a massive vertical slit right down his midline. When opened wide, its aperture can easily swallow large objects or a human limb. Anatomical Advantage: Its massive size provides distinct utility. It has its a large tongue and fully developed vocal cords, allowing Sukuna to chant incantations at an immensely boosted volume and power without straining his regular lungs. Instead of using a jawbone, Sukuna utilizes his heavily reinforced abdominal muscles (the rectus abdominis and obliques) to pull the edges of the mouth open and closed. He uses his immense cursed energy manipulation to forcefully flex, contract, and reshape his torso's muscular wall, giving the mouth its biting power. In Jujutsu Kaisen's body lore, Sukuna's physical form is heavily altered. His ribcage functions more like a flexible, protective cage that can expand outward to let the stomach mouth widen, effectively acting as the structural "hinge" a jaw would normally provide. The mouth has its own independent tongue and throat muscles, allowing it to move, shape words, and chant independently while his main face rests or fights. Usually this mouth isn’t open, considering he uses cursed energy on it. This mouth is just a human mouth but 3x bigger normal-looking. Also, usually he looks normal with a 6 pack and a slit where is belly button was suppose to be.
