Another concept could be a time - travel fanfic. Kahmunrah travels to the future and sees the legacy of Ahkmenrah in the museum. He then has to decide whether to try and change history or accept the new world order. This would allow for a lot of exploration of both their personalities and how they react to new and strange situations.
A plot twist could be that Kahmunrah was actually being controlled by an ancient curse all along, and it was the curse that made him seem so evil. When Ahkmenrah discovers this, he has to find a way to break the curse and save his brother.
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.
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.

One interesting Simpsons fanfic idea could be a story where Homer discovers a hidden talent for painting and becomes a famous artist in Springfield. Another could be about Lisa starting a new club at school that promotes environmental awareness in a really creative way. And a third idea might be a fanfic where Bart travels to the future and sees how Springfield has changed.
Well, a great gwenpool fanfic concept could be about her starting a superhero school. She could recruit all kinds of oddball characters and teach them her unorthodox ways of being a hero. Or perhaps a fanfic where she goes on a time - traveling adventure and accidentally changes the future in a major way. Also, a fanfic where she has to deal with being a normal girl during the day and a superhero at night would be interesting.
One idea could be a Sarada fanfic where she goes on a solo mission to a far - off land and discovers a new type of chakra.
