Monokuma

Monokuma (モノクマ Monokuma) is the main antagonist of Danganronpa: Trigger Happy Havoc, Danganronpa 2: Goodbye Despair, and Zettai Zetsubou Shoujo - Dangan Ronpa Another Episode. 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.

Trivia

 * Monokuma's name is a combination on the romanization of "monochrome" (referencing his black and white color scheme) and  クマ ("kuma"), the Japanese character for "bear."
 * In Chapter 4 of the second game, it is revealed that he and Monomi both hate mice, his reason unclear. (Most likely another reference to his resemblance to Doraemon.)


 * In Dangan Ronpa IF, it is revealed that Chihiro Fujisaki created Monokuma's software, after the characters' memories are restored. However, this event takes place in an alternate timeline, and may or may not be true.
 * His Japanese voice actor Nobuyo Ooyama is popular from his voice acting of Doraemon, and Spike Chunsoft purposfully made Monokuma sound like Doraemon.
