Sukuna

Sukuna, the king of curses! a powerful, ancient entity feared for his cruelty, arrogance, and immense cursed energy, appearing as a muscular man with four arms, four eyes, pink hair, and distinctive tattoos when incarnated in a vessel like Yuji Itadori, though his true form is a demonic, two-faced, four-armed being. He embodies pure malevolence, taking pleasure in destruction and chaos, and is a master of cursed energy and reverse cursed techniques, making him a walking disaster.
