If the original Danganronpa franchise didn't contain enough characters to feel sorry for, the Adaptation Expansion not only shook things up with the canon characters a bit, but also includes many OCs that have their own tragic backstories and share their places in the Despair-wracked world.
A New Hope
- The mastermind of the Killing Game, the original Makoto Naegi, who crosses over with Woobie, Destroyer of Worlds. Ever since he was Forced to Watch as a clone of himself stole his identity, he fell into Despair and lost the last of his humanity. He ran the Killing Game as a Roaring Rampage of Revenge, and ended it by blowing up the building to kill all of the remaining survivors until Kokichi and Usami came to save the day, even stabbing his clone when he was trying to forgive and reform him. Eventually, he accepts his fate as the building collapses around him. However, he turns out to have survived, and there's a good chance that he'll be seen again.
OC fics
Sea of Tranquility
- Rene Musil, who crosses over with Jerkass Woobie. After Miyaki and Mikhail were killed inside the greenhouse, Rene was sent a message about the event, resulting in him pointing out then-unknown evidence of the crime. He then goes into a Villainous Breakdown and gets voted guilty, with his final words being "I want to go home". It's later established that despite being an unlikeable jerk, he was still innocent and was unfairly framed. Is it any wonder he freaked out?
- Ren Seishin and Evan Drakon: These two go together for similar reasons. Ren had a cruel mother who abused him both physically and verbally, leading him to believe that his real voice was disgusting (until he opens up when Misuzu was nice to him). Meanwhile, Evan had a horrible father who raised him and his siblings when their mother died from childbirth. His father was an assassin who wanted his sons to follow in his footsteps, but killed them and left Evan all alone, initiating him to kill a family without hesitation, while threatening to kill his grandmother to make him colder, he ended up being killed by his outraged son. In the Killing Game, both Ren and Evan lost someone they formed a bond with (Miyaki for the former, and Hikari for the latter) only to be tricked into killing each other, then being brought back to life only to be mutilated horribly and relive their deaths all over again. And if that wasn't enough, the real killer Dylan defiled both Evan's identity and Ren's body as he evaded karma once more.
- Mallory Walsh: A Pollyanna with a childish demeanor, only to become an Iron Woobie as she has to cope with the Killing Game, and eventually the poor sweetheart is horribly killed by Dylan, who defiled the memorial and pulled his knife out on her (even when she trusted him) before carving a Glasgow Grin on her corpse's face. It's hard to see her crying for her parents as Dylan brutally murders her, one of his many atrocities. Sadly, even the omake isn't kind to Mallory either, as she's mentioned to be suffering from leukemia!
Kuma-Kuma Land
- Haruto Shinta: Despite being an Ultimate Parental Figure and a Nice Guy, he was the victim of an obsessive stalker who abused him both mentally and physically, which gave him PTSD and an aversion to touch. Since that moment, he's provided help and support for lots of kids including Kitai Riveros. With 9-year-old Annabelle as his new responsibility, he's fretted over her since Nagito's clone tried to kill her, to the point where seeing her traumatised caused him to snap and make an angry rant from his own worry, even calling Tomoko an inhuman monster, just like her. It really makes you think, just what did this girl do to Haruto to make him like this?
- Laris Nevermind: The illegitimate child of the King of Novoselic and Kirumi Tojo's mother, raised to be a knight. When Novoselic was attacked by Despair, Laris left under the king's order, and regrets leaving the kingdom to be destroyed. In the game, the Knight often engaged in Heroic Self-Deprecation out of guilt, which worsened with Haruto's breakdown.
- Kaizoku Dokuro: When he was little, he always wanted to impress his father Kokai Dokuro, the Ultimate Naval Mechanic. He tried to make a motor to get Kokai's attention, but accidentally caused an explosion that ended up killing him instead, while Kaizoku was left with permanent scars all over his body. When confronted, he tried to blame his father for the explosion as he was afraid of taking the blame, yet his mother grew bitter and said it was his fault.
- Dolly Dewitt: Abused by her drunken parents and relentlessly bullied by other kids, she became misanthropic and distrustful towards people, while believing that dolls can be her only friends. Her doll Becky's Jerkass personality can be interpreted as her lashing out at the world. Thankfully, Dolly finally gets a chance to experience kindness in the park, with Haruto comforting her on the rollercoaster and Naruhiko empathising with her and considering her as a friend, which lets Dolly show a sincere smile.
- Patrick Walsh: The cousin of Mallory Walsh, he was abandoned by his father and forced to look after his little sister Sarah. He is blackmailed into murder when he is threatened with a ransom for Sarah's life, while being shown a picture of Mallory's corpse to show what they're going to do with her. He is eventually found guilty and executed, with his last words showing his regret for failing to save Sarah. And going by what happened to Kanon...
