One idea could be a 'what if' scenario. For example, what if Midoriya didn't inherit One for All. This would completely change the story's dynamic. He might have to rely on his own intelligence and strategic thinking to become a hero in a different way. Another idea could be a time - travel fanfic. A character goes back in time and tries to prevent a major disaster that happened in the original series. This could lead to a lot of interesting interactions with past versions of the characters.
A fanfic about the characters in an alternate universe where quirks are not used for heroics but for something like art or sports. For instance, Bakugo could be a famous athlete using his explosion quirk to enhance his performance. Or a story where the villains and heroes have to team up against a common, greater threat that neither side can handle alone. This would force them to put aside their differences and work together, which would be full of drama and character development.
You could write a fanfic focused on the daily lives of the students outside of the hero training. Show how they interact with their families, how they study for normal school subjects, and their hobbies. It could be a slice - of - life type of fanfic that gives a deeper look into the characters' personalities when they're not in the heat of battle or training.
