Monokuma

Monokuma (モノクマ Monokuma) is the main antagonist of Danganronpa: Trigger Happy Havoc, and Danganronpa 2: Goodbye Despair. He is a strange teddy bear who proclaims himself to be the principal of Hope's Peak Academy and initiates a life of mutual killing among the students, being the manipulator for everyone to experience the dog-eat-dog world and despair within their hearts (except optimistic students like Makoto Naegi's hope are immune to his despair plan).

Prior to the series, this cunning and vile being is actually a model animatronic bear used as an avatar to interact with the students by the mastermind. There are seemingly infinite copies of Monokuma, and he seems to have the ability to teleport also everywhere within the academy compounds. He is Usami's, as "brother", who later renamed as "Monomi".

Appearance
Monokuma's entire face and body splits equally down the center into two sides. It resembles the Yin-Yang symbol of which there's a balance between good and bad. In some occasions, Monokuma would show his good side in regular conversation but would turn to his bad side when he's angry, merciless, or ruthless.

His right side is white in color and has the classic teddy bear expression. His left side shows a more sinister look. It's black in color and has a red slash for an eye and an evil, stretched grin. Although he is entirely split into two opposite sides, the only parts of Monokuma that aren't affected by the split is his muzzle and belly area; which both remain white. He also has a large and obvious bellybutton on the lower part of his belly. His bulging navel has an X mark on it.
