NOTE: THIS IS ONE OF THE FEW ROLES THAT WE WOULD LIKE TO SOUND SIMILAR/CLOSE TO THE JAPANESE VOICE.

Monokuma's personality is one of Junko's personalities which she uses in the First Killing Game when controls him. Despite being an avatar of two vastly different people, Monokuma's personality had been kept consistent with the Junko's, which is divided into two separate parts: his “right”, or “white” personality resembles a normal teddy bear who will act cute, innocent, or even patronizing. As such, during the times where this side of Monokuma is active, he may come off with a polite demeanor. Monokuma's “left”, or “black” personality is a malicious, evil, and a cruel bully who would do anything for the sake of despair. He can switch between these traits at the drop of a hat, making him unpredictable for his students to deal with.

When upset or bothered, Monokuma will attack the cause as an effect, yet most of the time, he may hold himself back, under the claim that he cannot hurt his 'beloved students'. When amused, Monokuma often gives his signature laugh, a sadistic “upupupu”. He takes every opportunity to belittle the students, claiming that they are responsible for everything bad that happens in the school. Monokuma dislikes people who don't obey him and will threaten those who oppose his command.
