A great idea for Crooked Kingdom fan fiction would be to focus on the relationships between the characters outside of their criminal activities. For instance, write about a time when Jesper and Wylan have a day off and just explore the city together, having normal conversations and getting to know each other on a deeper level without the pressure of a job.
One idea could be exploring the backstories of the minor characters in the Kingdom Hearts universe. For example, delving into the past of the different Keyblade wielders we only briefly see. Another idea is to create an alternate timeline where Sora makes different choices during his adventures. Maybe he sides with the villains for a while to understand their motives better. Also, you could write a fan fiction focused on the relationship between different worlds in the game, like how the world of Wonderland affects the world of Olympus Coliseum.
One great post 'Crooked Kingdom' fan fiction could be about the further adventures of Kaz and his crew in a new heist. Maybe they take on a powerful merchant guild in a different city. It could explore how their relationships have developed since the events of the book.
One possible plot idea could be a new adventure where the main characters from Kingdom Hearts find themselves in a digital world created by the topless robot. Maybe they have to solve puzzles related to the robot's programming to find their way back to their normal world.
First, re - read Crooked Kingdom to really get a feel for the characters, their voices, and the world they live in. Then, start with a simple idea, like a small adventure for one of the characters. For example, you could write about Kaz going to visit an old acquaintance from his past that we haven't heard about in the books.
First, really understand the characters from 'Crooked Kingdom'. Know their personalities, their goals, and their relationships. Then, think of a new situation or conflict for them. It could be something related to the world Leigh Bardugo created, like a new magical threat or a new criminal underworld plot.
Well, you could write a fan fic where the relationships between the characters are reversed. So if in the original there are certain rivalries, in the fan fic they become allies and vice versa. Also, a story about a character who loses their power but discovers a new way to be strong within the 'unordinary' world would be interesting. Or how about a fan fic that takes place in a parallel dimension within the 'unordinary' universe where the rules of powers are slightly different?
Some interesting ideas for Riverdale fan fiction could be a crossover with another popular teen drama. Imagine the characters of Riverdale meeting the characters from 'Stranger Things'. It would be really cool to see how they interact. You could also write a fan fiction that focuses on the future of Riverdale. What will happen to the town and its residents ten years from now? Will Archie still be in town? How will Veronica's business empire develop?
You could write a fan fiction about a Pokemon trainer who has the unique ability to communicate with Pokemon on a deeper level than others. This trainer goes on a journey to solve the mystery of why some Pokemon are becoming more aggressive. Along the way, they meet different Pokemon species and form strong bonds with them. They might discover that there is an unseen force affecting the Pokemon's behavior, like a new type of pollution or an ancient curse.
One idea could be to write a fan fiction where Bluey and her family go on an adventure to a magical land. They could meet new characters and have to solve puzzles to get back home.
Some cool ideas for Pokemon fan fiction are stories about Pokemon with unique abilities that are different from what's in the games or anime. For example, a Pikachu that can fly. Or a fan fiction about a group of misfit Pokemon who form their own team to compete in the Pokemon League against the traditional trainer - led teams. You could also write a fan fic that delves into the origin of a particular type of Pokemon, like how the Ghost - type Pokemon came to be.
