Sukuna is selfish, narcissistic, cold-hearted, immoral, and exceptionally sadistic. When he was reincarnated shortly after Yuji ingested his finger, he commented, implying the slaughter of women and children and likening them to maggots crawling around. Due to his immense power, he rarely cares about the consequences of his actions, Sukuna is a tall and muscular man with four arms, four eyes, and a large mouth on his stomach.
