Monokuma is a stuffed robotic bear and the self-proclaimed Headmaster of Hope's Peak Academy who instigates the Killing School Life. He seems very easygoing and cheerful at first glance, but with a very sinister undertone. However, he always rather quickly reveals his evil nature by describing killing games and his desire for despair, and he is very well known for his habit to say and do whatever he wants to. He loves hysteria, violence, and chaos. He also has his own signature laughs, a sadistic "puhuhu" and a mocking "ah-hahahaha". He can also be immature and childish, often acting sarcastic and mocking towards the students, and occasionally dramatically pretending to be offended when rightfully accused. In general, he cracks a lot of jokes (especially bear puns) and breaks the fourth wall often.
