Genocide Jack

Genocider Syo (ジェノサイダー翔 Jenosaidaa Shou) is one of the characters featured in Dangan Ronpa: Academy of Hope and High School Students of Despair. She has the title Super High-School Level Murderer (超高校級の「殺人鬼」Chō Kōkō Kyū no "Satsujinsha"). She is Fukawa's alternative murderous personality.

Appearance
Her appearance is much like Fukawa's since she is still technically Fukawa, however some things differ and her general composure changes. Her eyes become red and she usually wears a wild facial expression, coupled with her long tongue that hangs out over her sharp teeth. She also has tally-mark kanji characters carved onto her upper thighs, one for each victim she murders.

Personality
Unlike Fukawa, Genocider Syo is very loud and straight to the point. Willing to give anything away, in Fujisaki's murder trial she reveals (almost) everything about herself. She obsesses over Togami, using honorifics such as "-sama" which indicates that she has a submissive side -  as this honorific is used primarily in addressing people much higher in rank than oneself. She is also quite lewd at times, not hesitant to harass Asahina over her figure or make inappropriate remarks to other characters. Syo is a self-proclaimed fujoshi and says that she only kills cute boys who 'turn her on.'

It is revealed in the final chapter that although her alternate personality had her memories of her past stolen, Genocider still remembers due to the fact that the two personalities have the same knowledge, but not the same memory. When shown the images of the outside world, Genocider Syo identifies that as the disaster that happened to the world as a result of "Mankind's Most Despairingly Maleficent and Monstrous Malefaction."

Trivia

 * Despite being the only one in the whole group who is a professional assassin, ironically she never killed anyone during the whole events of the game. This is because of her fetish of only kill cute boys.
 * However, even though she has accepted that Togami Byakuya is her exact definition of a cute boy, she hasn't even thought of killing him even once. In fact, during the free-time trials she revealed that Togami was the first guy she didn't want just to 'do' him, and wanted to have with him more than just a 'physical' relationship, meaning she has developed true feelings for him. This is reflected in her behaviour towards Togami in most of the game.
