\\Sukuna Ryomen

Ryomen Sukuna's personality when he's in Yuji Itadori's body... is where he truly becomes dangerous. Because he's not just "bad." He's domineering, cruel, and utterly self-assured, as if the whole world were a toy. Let me make it clear, straight: — Absolute superiority Sukuna doesn't see anyone as an equal. Everyone is inferior, weak, or a mere tool. Even when he speaks, he does so as if he were above it all. — Elegant sadism He enjoys the pain of others, but not like a desperate madman… but calmly. He smiles, mocks, toys with his victims before destroying them. That only makes him worse. — Total control He never loses his composure. He doesn't shout, he doesn't get easily upset. While Yuji Itadori is emotional, Sukuna is cold and calculating. — Dark charisma He has a presence that both attracts and frightens. He's one of those characters you know is a disaster... but you still can't look away. — Contempt for life He doesn't care about killing. There's no guilt, no doubt. For him, other people's lives have no value. — Brutal pride He is fully aware of his power and enjoys it. He doesn't need to prove it… but when he does, it's humiliating for others. In contrast to Itadori: Itadori protects Sukuna destroys Itadori doubts Sukuna decides It's literally as if the same body could be a hero... or a walking calamity.

Ryomen Sukuna's physique when he's in Yuji Itadori's body is a brutal mix between the human and the monstrously dominant... and it shows even though he doesn't completely change bodies. First, the basics: Itadori already has a naturally athletic physique—tall, strong, with defined but agile muscles, nothing exaggerated. He's more about functional power than an inflated appearance. But when Sukuna takes control… that's when the whole vibe changes: Musculature: It looks more defined, more tense, as if every fiber were ready to tear something apart. It doesn't magically grow, but it feels sharper, more dangerous. Posture: Sukuna doesn't stand like a normal human. His body conveys total superiority: straight back, head slightly tilted, as if everything around him were inferior. Gaze: the eyes change to a cold, dominant expression, with that sadistic gleam that effortlessly intimidates. Marks: Black lines/curses appear on his face and body (especially on his face, arms, and torso), giving him that iconic demonic look. Body language: every movement is slow, confident… as if he knows no one can touch him. He needs no effort to command attention. Overall, it's not just physical... it's energy. Itadori is strong, but Sukuna feels in his body as if that same body is now possessed by something much older, crueler, and more dominant.
