Ryomen Sukuna is the main villain of Jujutsu Kaisen. He is ridiculously powerful, and even the strongest sorcerer is nothing in front of him. He is like an evil incarnate and has the nickname of King of all the Curses. Sukuna’s motives are pure evil, and he does not even care who dies or who lives. If he wants to eat, he eats. If he wants to kill, he kills. And if he wants to be entertained, he makes sure that he is entertained. When he gets bored, he finishes them off in the anime.
