Another interesting concept is a fanfic where Shigaraki and Dabi are forced to work with heroes for a common goal. Their initial reluctance and gradual acceptance of the situation, along with their interactions with the heroes, could make for a great story.
A shigadabi fanfic could explore their backstories and how they might have met before joining the League of Villains. Maybe they had a chance encounter during a difficult time in their lives that led to an unspoken understanding between them.
A great Shigadabi fanfiction might be a story where they get lost in a mysterious place. They have to rely on each other to survive, and during this process, their bond deepens. There could be moments of tension, but also unexpected moments of kindness and cooperation between them.
First, you should study the characters of Shigaraki and Dabi. Know their personalities, quirks, and how they interact in the original My Hero Academia series. Then, come up with a basic plot idea, like a conflict they have to face together.
Well, in '1984 fanfic', one interesting idea could be exploring different endings. Maybe the main character manages to overthrow the totalitarian regime in a way not shown in the original. Another could be delving deeper into the relationships between characters that were only hinted at in '1984'. For example, the relationship between Winston and Julia could be explored further, like what if they had a chance to start a real family in a post - Big Brother world.
One idea could be to focus on the ammonite's daily life in the prehistoric ocean. Maybe it's a young ammonite trying to find its place among the coral reefs and other sea creatures.
One interesting idea could be a doom fanfic where the protagonist is a new recruit in the Doom Slayer's army. They have to learn the ropes and face off against demons in a training scenario that goes horribly wrong, leading to an unexpected adventure. Another could be a fanfic set in a post - Doom world where the remaining humans are trying to rebuild and there are still hidden pockets of demonic activity that they have to deal with. And a third idea could be a fanfic that explores the backstory of one of the demons, perhaps giving it a more sympathetic angle before it became a monster in the Doom universe.
You could write a fanfic where Lionheart teams up with an unlikely ally. This could lead to some interesting character development and new story arcs. Also, a fanfic about Lionheart's love life could be engaging, like who he might fall in love with and how that relationship would change him.
One idea could be a story where Batman has to team up with his rogues gallery to fight a greater threat from outer space. Maybe the Joker, Two - Face and the Riddler are forced to put aside their differences when an alien race starts to invade Gotham. They find that Batman's strategic mind and their own unique skills are needed to save the city.
One idea could be a modern - day Cinderella where she is a struggling artist in a big city and meets her prince at an art gallery. Another could be a Cinderella in a steampunk world, with all the mechanical gadgets and a unique take on the classic story. Or perhaps a Cinderella fanfic where she is a mermaid - like creature in an underwater kingdom and the prince is a sailor who discovers her world.
One idea could be a Sonic fanfic where Sonic and his friends travel to a parallel universe where the roles are reversed. For example, Eggman is the hero and Sonic is the villain. It would be really cool to see how they handle this new situation.
One idea could be a fanfic where the characters from AATC go on an adventure to a new and mysterious land. They could encounter strange creatures and have to use their unique skills to survive.
