Some fanfictions might explore a world where the rules of the 'Danganronpa' game are completely different in 'Watch the Future'. Instead of the killing game, it could be a competition of wits where the losers are just sent home. This would change the motives and actions of the characters completely. Also, a fanfic could center around a character who discovers they have special powers that could either help or hinder the progress of the game.
A possible plot in the fanfiction could be a time - travel twist. What if a character goes back in time to prevent the events of 'Danganronpa Watch the Future' from ever happening? This would change the entire dynamic of the story and relationships between characters. Or, the fanfic could focus on a romance that was only hinted at in the original. It could develop the relationship between two characters who had a lot of unspoken chemistry.
One idea could be exploring an alternate ending where the characters find a way to break free from the game's cycle without any deaths. Another could be a story focused on the backstories of the characters that were not fully explored in the original, like how they ended up in the situation of the game in the first place.
One idea could be to cross Danganronpa 2 with another popular game like Persona. The characters from Danganronpa 2 could find themselves in the world of Persona, dealing with the Shadows and having to adapt their skills. For example, Hajime could learn to use a Persona and use his detective skills to solve the mysteries related to the Dark Hour. Another plot idea could be a crossover with a fantasy world. The Danganronpa 2 characters are transported to a magical realm where they have to face new challenges. Maybe they have to fight dragons or solve magical riddles, all while still dealing with the underlying distrust and mystery that is characteristic of Danganronpa. A third idea is to cross it with a post - apocalyptic world. They have to survive in a desolate landscape, find resources, and deal with new threats, all while trying to figure out if there's a way to get back to their own world.
Maybe the Velvet Room attendants from Persona start showing up in the Danganronpa setting. They offer the students a chance to awaken their Personas, but there's a catch - they have to face a series of trials similar to the class trials in Danganronpa. This could create a really unique and tense situation.
Maybe in this fanfiction, The Flash watches a future where Central City is in ruins because of a new type of meta - human threat that he has never faced before. So he starts training in the present to develop new powers or techniques to be able to combat this future threat. He could also try to find and recruit other meta - humans who might be able to help him in the future fight.
One idea could be that Ladybug and Chat Noir face a villain who can manipulate time in the future. This would force them to not only fight in the present but also find a way to prevent the villain from causing chaos in the future. Another plot could involve a new Miraculous holder from the future coming back to help them in their present battles, bringing with them new powers and a different perspective on their fight against evil.
One idea could be that the characters from Danganronpa are transported to the Fairy Tail world. They could be forced to participate in a Grand Magic Games - like event where the losers face a 'punishment' similar to the Danganronpa executions. This would create a high - stakes and tense situation as the Danganronpa characters are not used to this kind of magic - based competition.
One idea could be that Monokuma, in an unexpected turn, decides to spare Makoto from a difficult trial situation. Maybe he sees something unique in Makoto's will to survive and his positive attitude. This could lead to a strange sort of alliance where Makoto tries to understand Monokuma's motives better.
One idea could be that the OC is a new student in the Danganronpa world and Kirigiri takes it upon herself to protect the OC from the various dangerous situations. Maybe the OC has a special ability that catches Kirigiri's attention and they team up to solve the mysteries around them.
You could do a crossover with the Final Fantasy series. Picture the Danganronpa characters in a world filled with magic, summons, and complex job classes. They might have to complete quests or battles to progress, and the killing game aspect could be intertwined with the battles against powerful Final Fantasy monsters. For example, the murderer could gain power-ups from defeating certain bosses.
Maybe the Danganronpa characters get transported to the world of My Hero Academia. They then have to adapt to a world where having superpowers is normal. Some of them might try to use their unique skills from the Danganronpa world to become heroes or villains in this new setting.
