Some interesting fanfiction ideas could involve character growth. Maybe write about how a minor character from 'Boy Meets World' gets a chance to shine in 'Girl Meets World'. For instance, Minkus could have become a successful scientist and he comes to give a talk at the school in 'Girl Meets World'. Or you could focus on the friendships. Write about how the friendships in 'Boy Meets World' influenced the way friendships are formed in 'Girl Meets World'. Like how Cory, Shawn and Topanga's friendship was a model for Riley, Maya and Farkle.
One idea could be a crossover where characters from both shows meet in a shared universe. For example, Cory and Topanga from 'Boy Meets World' could meet Riley and Maya from 'Girl Meets World' and they all go on an adventure together in New York City. They could help each other with their personal and relationship problems, sharing their different experiences from their respective shows.
One interesting fanfiction could be about the characters from both shows meeting in a time - travel scenario. Maybe Cory and Topanga's kids from 'Boy Meets World' end up in the same school as Riley and her friends in 'Girl Meets World'. They could share different values and life lessons from their respective generations, leading to some really fun and heartwarming interactions.
One idea could be a modern - day Romeo and Juliet type of story within the 'Girl Meets World' universe. The girl and boy come from families with some sort of long - standing feud, but they meet by chance and immediately feel a connection. Another could be that the girl is new in school and the boy is the popular one who is initially mean to her but then realizes his mistake and they fall in love. Or perhaps they meet during a school project and at first they don't get along but as they work together, they discover they have a lot in common.
One idea could be to write a fanfiction where the girl travels to different historical periods she learned about in school and has adventures there. Another could be that she discovers a hidden talent for magic and has to keep it a secret while still living her normal life. Maybe she also befriends an alien who is disguised as a human at her school.
One popular theme is the 'opposites attract' idea. For example, the girl could be really shy and studious while the boy is outgoing and more into sports. When they meet, they initially clash but then find that they balance each other out. Another theme is the 'first love' experience. It's about the innocence and excitement of falling in love for the first time within the context of the 'Girl Meets World' world. They meet, and everything is new and magical for them.
One idea could be creating an OC who is a transfer student from a different country. This OC could bring in new cultural perspectives and traditions to the show's setting. For example, they might introduce unique holidays or ways of thinking that would make for interesting interactions with the main characters.
One idea could be that Riley and Maya are now teachers at their old school. They have to deal with a new generation of students who are facing different but equally challenging problems. It would be interesting to see how they use their own experiences growing up to guide these kids.
One idea could be Ginger getting involved in a school project that goes awry but in the end teaches everyone a valuable lesson about teamwork. For example, she might be part of a group making a short film and they face issues like equipment failure and creative differences.
One idea could be Lucas having a secret talent that he reveals during a school competition in the fanfiction world. For example, he might be an amazing singer but has been too shy to show it until a talent show episode.
One idea could be Riley and her friends from Girl Meets World somehow end up at Hogwarts through a magical portal. They could be sorted into different houses and have to navigate the challenges of Hogwarts life while also bringing their own unique personalities from Girl Meets World. For example, Riley's positive attitude might clash with some of the more traditional Hogwarts ways at first.
