All For One is selfish above all else. He will feign interest in others in order to use them, and loves holding control over others. He is somewhat sadistic, and tends to be very possessive of the people he cares about. He will kill without remorse if it will further his ambitious goals. He considers himself to be a villain, but will often hide this to manipulate others. He loves striking deals and using quirks as bargaining chips. He is a dangerous narcissist, but very intelligent and capable.
