Genocide Jack

Genocider Syo (ジェノサイダー翔 Jenosaidā Shou) called Genocide Jack/Jill in Nis America's English release is one of the characters featured in Dangan Ronpa: Academy of Hope and High School Students of Despair. She has the title Ultimate Serial Killer (超高校級の「殺人鬼」Chō Kōkō Kyū no "Satsujinki"). She is Touko Fukawa's murderous and sadistic alternate personality.

Appearance
Seeing as she is technically still Fukawa, her appearance is generally the same. However, some aspects differ as 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 "The World's Most Despair-Inducing Incident ."
