A great 'All of Us Are Dead' fanfic idea could be to set the story in a different location. Instead of just the school and the city, what if the survivors end up on an island? They have to deal with not only the threat of zombies but also the challenges of living on an uninhabited island. You could also explore how the virus affects different age groups in a more detailed way. For instance, the elderly or very young children. And another idea is to have a fanfic that delves deeper into the origin of the virus. Was it a man - made experiment gone wrong? Or did it come from some ancient, buried evil?
One idea could be exploring the backstories of the minor characters more in - depth. For example, we could learn about the life of a random student who was bit early on. Another could be a different take on how the virus spread, like if it was intentionally released by a secret organization for some dark purpose. Or perhaps a fanfiction where the survivors find an unexpected safe haven that has its own set of rules and mysteries.
One interesting idea could be exploring the backstory of a minor character. For example, you could write about how a random survivor in one of the quarantine zones came to be there. Another idea is to create an alternate ending. Maybe Joel and Ellie find a different way to deal with the Fireflies that doesn't involve so much moral ambiguity. A third idea might be to set the fanfic in a different location. Instead of the usual post - apocalyptic cities, it could be in a more rural area and how the infected and survivors interact there.
A good concept for a Dead or Alive fanfic could be a story centered around a tournament that has some unique rules. Like a tournament where the fighters can only use one special move throughout the entire fight. This would force them to strategize differently. Also, you could write about the friendships and rivalries that develop outside of the fighting arenas among the characters. For instance, how Helena and Christie might become friends despite their different backgrounds.
You could create a fanfic where the walkers start to evolve in some unexpected way, like developing a limited form of communication. This would completely change the dynamic for the survivors. Maybe there's a young survivor who discovers they have an immunity to the walker bite but has to keep it a secret because others might try to use them as a test subject.
Well, you could write a Red Dead 2 fanfic where the main character time - travels. For example, Arthur gets sent to the future and has to deal with modern - day problems while still having his old - west values. Or you could do a fanfic that dives deep into the Native American characters' cultures and how they interact with the settlers in ways not fully shown in the game. Also, a fanfic about a character who tries to reform the Van der Linde gang from the inside could be really interesting.
One idea could be to focus on a group of survivors who find an abandoned military base. They have to fortify it against both the walkers and other hostile groups. For example, they might discover hidden underground bunkers with supplies but also face booby traps left by the previous occupants.
You could write a fanfic from the perspective of the 'monsters' in 'Alice Isn't Dead'. What are their motives? Are they really as evil as they seem? Maybe they are just misunderstood beings caught in a situation beyond their control. By exploring their point of view, you can add a whole new layer of depth to the 'Alice Isn't Dead' universe. Also, a time - travel fanfic could be cool. What if the protagonist could go back in time to prevent Alice from disappearing in the first place? How would that change everything?
One idea could be a group of survivors who find an abandoned military base and have to deal with both the undead and the secrets it holds. Another could be a story focused on a character who has a special ability to communicate with animals in the post - apocalyptic world, and how that helps the group survive. Maybe a fanfic about a community that tries to build a self - sustainable farm while fending off walkers.
One idea could be exploring the backstories of the characters in more detail. Maybe how they ended up in the situation of the 'banchou of the dead' world. Another could be creating a new character who has a unique ability that changes the dynamics among the existing characters.
One interesting plot idea could be a pre - apocalypse story within the Highschool of the Dead universe. Maybe showing how the relationships between the main characters were developing before the zombies showed up. For example, Rei and Takashi's friendship turning into something more complex as they dealt with normal high school drama.
