Genocide Jack, known as Genocider Syo (ジェノサイダー翔 Jenosaidā Shō) in the original Japanese version, is one of the characters featured in Danganronpa: Trigger Happy Havoc.

Genocide Jack has the title Ultimate Murderous Fiend (超高校級の「殺人鬼」chō kōkō kyū no “satsujinki”). She is Toko Fukawa's murderous and sadistic alternate personality. She also once referred to herself as Genocide Jill as a joke, making a nod to her true gender.[1]

Genocide Jack also appears in Danganronpa Another Episode: Ultra Despair Girls as a second playable character in order to aid Komaru Naegi's adventure.


Genocide Jack's appearance is generally the same as Toko's, since they share the same body. However, some features differ: her eyes become red, and she wears a wild facial expression. She has a long tongue that hangs out of her mouth over her sharp teeth.

She has tally-marks carved onto her upper thighs, a count of how many people she has killed. Jack's reference art reveals that she has a container for her scissors attached to her right thigh. In the Danganronpa spin-off game, her hair flows freely instead of being kept in braids and is slightly messier than Toko's.


Genocide Jack is blood-thirsty and potentially very dangerous, but she is mostly portrayed as a comic relief. She laughs a lot and sometimes pretends to be serious only to reveal that she is just joking.

Unlike Toko, Genocide Jack is very loud and outgoing. During Chihiro Fujisaki's murder trial she reveals everything about herself. She obsesses over Byakuya Togami, calling him "Master" in the English version. In the Japanese version, she uses honorifics in 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 quite lewd at times, not hesitant to harass Aoi Asahina over her figure or make inappropriate remarks to other characters. Jack is a self-proclaimed fujoshi and says that she only kills cute boys who 'turn her on'. She also seems to like yuri, though she says that she's not into girls. She has also been portrayed with both sadistic and masochistic traits.

She has a habit of giving nicknames to others; for example, she calls Makoto Naegi "Big Mac", "Mahkyutie" and "Macoco Chanel."

It is revealed in the final chapter of the first game that although Toko had her memories stolen, Jack 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, Jack identifies it as the aftermath of “The Tragedy”.

It is also revealed in Chapter 4 of Ultra Despair Girls that she shares the same emotions and feelings with her alter. Their relationships with their peers are shared between them.

She occasionally has a much more serious side in Ultra Despair Girls. According to the limited artbook, "her attitude can switch between serious and crazy in an instant."


Prior to the Tragedy

Genocide Jack is a murderous fiend who killed any man she found handsome. She murdered all of her victims by crucifying them with her Genoscissors. Her victims were also written about in the Genocide Jack's secret book. In one of her free time events she revealed that her very first victim was her/Toko's first love, one of her elementary school classmates who moved to Shikoku.

She states Toko's life in a repressed modern society caused an unexpected reaction that created Jack, the polar opposite of Toko. In Ultra Despair Girls, Toko revealed that Genocide Jack was the result of her rough and often neglectful home life.

Danganronpa: Trigger Happy Havoc

Chapter 2 - Boy's Life of Despair

Genocide Jack first appeared in the second trial after Toko was forced by Byakuya to reveal her alter. Byakuya intended to frame Genocide Jack for the murder of Chihiro, but the murderous fiend pointed out that the apparent mimicry of her killing methods was "shoddy", as she refused to use anything other than her signature Genoscissors to murder and crucify her victims. She was further vindicated by the fact that she only targeted men she considered "handsome" - since Chihiro's secret had not yet been revealed to her at the time of his death, Genocide Jill would not have targeted him in the first place.

Chapter 3 - A Next Generation Legend!

Throughout the game, Genocide Jack would appear after Toko sneezed or fainted from the sight of blood, as noted when she follows the other students to investigate the third floor, the murder investigation and the third class trial.

Chapter 4 - All●Star●Apologies

She appeared again in Chapter 4 after Toko lost consciousness due to shocked by the appearance of injured Sakura Ogami who previously attacked by Yasuhiro Hagakure with a Monokuma bottle. Jack then take the same action with Hiro, she hit Sakura with a Monokuma bottle and it allow Sakura to lost consciousness again. Before she left the rec room (the crime scene), She cleaned the bottle fragment to the nearby trash can. During the trial, her honesty and the evidence presented on the several crime scenes proved her innocent.

Chapter 6 - Ultimate Pain, Ultimate Suffering, Ultimate Despair, Ultimate Execution, Ultimate Death

She and Toko survive the last trial and escape with other survivors at the end of the game.

Danganronpa Another Episode: Ultra Despair Girls

Toko/Jack appear as the deuteragonists who aid Komaru in her journey to rescue Byakuya, utilizing their beloved Genoscissors in defeating Monokuma.

Chapter 1 - Crying for Love in Hell

Genocide Jack appears for the first time when Komaru lands on a building rooftop which was later revealed as a hospital after she fell out from the Warriors of Hope's base. She immediately defeated the Monokumas who came after Komaru and asked the person who she just saved whether she was "Komaru Naegi" or not.

After Komaru confirmed that she was Komaru, more Monokuma Units appeared from every side of the building. Jack then decided to bring Komaru to a safer place. She asked Komaru whether she knew Byakuya or not because she could smell his aroma from Komaru's Megaphone Hacking Gun. When a confused Komaru didn't answer fast enough, Jack begins a countdown. Before she could do anything, she suddenly switched back to Toko.

Toko, who could now manage Jack, confirmed they were allies and that she would help her escape from the Monokuma unit. She explained that Genocide Jack had been completely tamed by her using a stun-gun and would not commit murder again like in the past, but she would only would use the stun-gun when the circumstances were right, because if she used it too many times, it would fry her brain.

Chapter 2 - Legend of the Revolution

During Toko and Komaru's journey in the tunnel, suddenly an earthquake struck and made the ceiling collapse. Toko who collapsed after a big cracked rock hit her switched to Genocide Jack who quickly dashed back to the entrance followed by Komaru.

On the way, Monokuma Kids appeared and blocked their escape route. But they repeatedly withdrew from one point to another point after Genocide Jack defeats the Monokumas around the tunnel. At the very last second Komaru and Jack managed to escaped the destroyed tunnel. Komaru questioned why Toko's personality suddenly switch and Jack answered that when they go unconscious and sneezing could switch her personality.

After Jack sneezed and switched to Toko again, Komaru suddenly depressed and wonder if she couldn't really escape from Towa City. Just before Toko could rally Komaru again like she did after Yuta Asahina's death, two Monokuma Kids approached them with a TV that connected to the Warriors of Hope headquarter and Jataro Kemuri, one of the Warriors of Hope's member appeared on the screen.

Chapter 3 - Cute Girl's Battlefield

Toko switched to Genocide Jack when she was being apprehended by the Resistance inside a cell in Resistance secret base. She quickly broke out and visited Komaru's cell, only to find out that she was already gone. She encountered Monokuma Kids who gave her Komaru's hacking gun, her own stun gun, and a wristband GPS which led to Komaru's position.

Jack quickly arrived on the surface and wondered why the GPS moved so fast until she found a train driving fast on the monorail. She then broke inside the train in order to save Komaru.

Finally, Jack arrived at the room where Komaru was being tortured by Kotoko and she was able to defeat Kotoko. The train then flew off the track and hit a building. Komaru hugged Jack and apologized for the fight she had with Toko. Jack said that she has no right to accept the apology. She eventually sneezed and switched back to Toko.

Genocide Jack appeared again when Kotoko was about to be executed by Monokuma Kids after losing her fight with Jack and Komaru. Her reason to save her was to get some information about Byakuya's whereabouts.

    • Her blood type is O,
    • Her chest is 31 in.

  • In Ultra Despair Girls, one of Jack's "smiling" sprites is awfully similar to that of Nagito Komaeda from Danganronpa 2: Goodbye Despair.
  • Her usage of scissors and superhuman skills with them may be a reference to Mikoto Urabe of Mysterious Girlfriend X. The marks on her upper thigh revealed when she shows off her scissorwork also mirrors the technique of this character.
