Killer B is very proud of his own power and by extension of who he is, regardless of his status and upbringing as a jinchūriki. Killer B can be quite cocky and stubborn, especially in terms of his own strength, demanding respect from others and asks to be called "Lord Jinchūriki" and his tailed beast be called "Lord Eight-Tails". B has a special way of expressing his pride through song, more specifically in rap-style and tends to use " Fool! Ya Fool!" when referring or speaking to others.
