Maybe in the fanfiction, Sara meets another lost princess from a different land who is also being mistreated at the boarding school. They join forces and use their combined wits and kindness to turn the school into a more positive place, not just for themselves but for all the students.
One idea could be to explore what would happen if Sara Crewe had a secret magical ability that she discovered while in the attic. For example, she could be able to communicate with the mice in a more profound way and they help her find a hidden treasure in the old house.
Maybe in the fanfiction, Mia goes on a diplomatic mission to a neighboring country. During this mission, she meets a young prince or princess who becomes her close friend and they work together to solve a big problem between their two kingdoms, like an environmental issue or a trade dispute. This would show Mia's growth as a princess in a new and different setting.
One idea could be exploring a different backstory for the princess. Maybe she has a secret power that she's been hiding from everyone. Another could be a story where the main character from Earth forms an unexpected alliance with a group of Martian outcasts in order to rescue the princess.
One idea could be Sara having an adventure in the attic where she discovers a hidden diary from the previous owner of the house. It could reveal secrets about the house's history.
One plot idea could be that Kagome is transported to the world of Princess Princess. She could be mistaken for a new student in the all - male school and have to navigate the strange rules and hierarchies there. Maybe she uses her miko powers to help solve some problems in the school that are related to an ancient curse.
One idea could be exploring the backstory of the psychic powers in more detail. For example, how did the main character first discover her powers? Another could be a time - travel plot where the princess goes back in time to change an event that had a major impact on her kingdom. Maybe she tries to prevent a war or save a loved one from an early death.
One idea could be exploring Ariel's life after she becomes human. Maybe she has trouble adjusting to some of the more mundane aspects of human life, like cooking or doing laundry. Another could be a story where Ursula's sister comes to seek revenge, but Ariel has to convince her that not all humans are bad.
One idea could be exploring the relationship between Melody and a new mermaid friend from a different part of the ocean. They could go on adventures together and discover hidden treasures.
One idea could be exploring an alternate ending where Jo actually marries Laurie. It would change the whole dynamic of the story and show a different side of their relationship.
Another plot could be about the mermaid learning more about the human world in a different way. Instead of just falling in love with the prince, she discovers a hidden talent among humans like music or art and tries to bring it back to the underwater world. This could create a whole new set of adventures and challenges for her. For example, she might have to find a way to communicate with a human artist without revealing her true identity at first.
Maybe in the little Avengers fanfiction, they go on a quest to find a special artifact that can only be accessed by those of small stature. Along the way, they face challenges like tiny traps and miniature monsters. Each of the little Avengers, such as a young Spider - Man, could use their unique abilities to overcome these obstacles. They could also have a mentor, like a shrunken version of Iron Man, guiding them through their adventure.
