One idea could be sending Doraemon and Nobita to a parallel universe where the rules of the gadgets are different. For example, the Anywhere Door takes them to a world where time moves backwards. Another idea is to have a new character join their group, a mysterious alien who has a gadget that can nullify Doraemon's gadgets, creating all sorts of chaos and new adventures. And a third idea could be a story where Doraemon loses all his gadgets and has to rely on his wits and the friendship with Nobita and the others to solve problems.
Some interesting Doraemon fanfiction concepts could involve time - traveling to the very beginning of Doraemon's existence. Maybe find out how he was created and the first time he used his gadgets. Another could be a body - swap story, where Nobita and Doraemon swap bodies and have to deal with each other's daily lives. This would be really funny as they have very different abilities and personalities. Additionally, a fanfiction could be written about a world where all of Doraemon's gadgets are real and available to everyone, and how that changes society and the relationships between people.
A cool crossover idea in Naruto and Doraemon fanfiction is having Doraemon help Naruto learn about different cultures and technologies from the future. For example, Doraemon could show Naruto how advanced medical technology could heal even the most severe ninja injuries. And Naruto could introduce Doraemon to the concept of ninja skills and the importance of willpower in his world. This exchange of ideas could lead to some really unique adventures and storylines.
One interesting Doraemon English story is about the 'Anywhere Door'. In this story, Nobita uses the door to go to all kinds of amazing places. It shows his adventures and how he gets into and out of trouble with the help of Doraemon's gadgets. It's really fun to read about his experiences in different lands.
In a Doraemon Hindi story, there is the gadget of the 'Memory Bread'. Nobita uses this bread to quickly learn for his exams. He just has to eat the bread and all the knowledge from the book he places on his head while eating gets stored in his memory. But it has a drawback. If he goes to the toilet, the knowledge goes away. This story is both funny and teaches about the importance of real study rather than shortcuts.
Another concept could be a time - travel - based crossover. Suppose Doraemon crosses over with Doctor Who. They could both explore different time periods and dimensions together. Doraemon's Time Machine and Doctor Who's TARDIS are both means of time travel, but they have different functions and appearances. Their combined adventures would be full of mystery and discovery.
One idea could be exploring what would happen if the Thundermans lost their powers permanently. It would completely change their dynamic and how they interact with the world and villains.
Some interesting Ghostbusters fanfiction concepts could be centered around the ghosts themselves. For instance, a story where a particular ghost has the ability to possess inanimate objects and uses this power to create chaos in the city. The Ghostbusters would then have to figure out how to stop it without causing too much destruction. Another concept could be a time - travel fanfiction where the Ghostbusters go back in time to prevent a major ghost - related disaster from ever happening. This could involve meeting their younger selves or influencing key events in the past related to the supernatural.
One idea could be a story where the zodiac signs are characters in a magical school. For example, Aries could be the brave and impulsive leader of a group of friends, always getting into adventures.

One idea could be to write about the littles' adventure in a new, mysterious land filled with strange creatures. Another could be their attempts to build a huge structure using only small objects they find.

For a 'the wilds fanfiction', you might consider a time - travel aspect. What if one of the characters could go back in time and change the events that led them to the island? Or a story where the island has some sort of magical or supernatural element. Maybe there are hidden caves with strange powers. Additionally, you could write about a character who has a secret skill or knowledge that helps the group in a whole new way, like a character who is an expert in survival techniques that she has been hiding until a crucial moment.
