One idea could be to explore what would happen if Naruto had a different kind of training, like learning from an ancient sage not known in the original story. Another could be a story where all the characters' personalities are swapped, creating a really unique and comical situation. You could also write about Naruto's journey in a parallel universe where the Akatsuki are actually the good guys.
For a 'naruto legend fanfiction', you might consider a story where Naruto time - travels. He could go back to the time when the Hidden Leaf Village was first founded and interact with the first Hokage. This would give a whole new perspective on the history of the village. You could also write a story where Naruto has to team up with his enemies to fight a greater threat, like an alien invasion or some sort of ancient evil that awakens from a long slumber. This would force him to put aside his differences and work with people he never thought he would.
Well, in this fanfiction, perhaps Naruto's banishment leads to him exploring different ninja techniques from other lands. He could combine these with his own skills, like his shadow clone jutsu, to create something entirely new and powerful. It could also show how he overcomes the stigma of being banished and rises above it.
A plot could also revolve around the idea of the Brutal Legend world influencing the Naruto world in some way. Maybe a strange energy or magic from the Brutal Legend world seeps into the Naruto world, causing chaos. The ninja have to figure out what it is and how to stop it. This could involve a lot of exploration of the differences and similarities between the two worlds, and how the ninja use their own skills and abilities to combat the new threat.
One idea could be a story where Naruto and Korra meet in a dimension where the worlds of their respective shows collide. They could team up to fight a new, powerful enemy that threatens both their universes. Another idea is a time - travel story where Korra goes back in time to the Naruto era and has to adapt to the different ninja world while also sharing her bending knowledge.
Another idea is a fusion of their powers. Maybe Link could gain some of Naruto's chakra and use it in a unique way. He could infuse his sword with chakra to make it stronger or perform new combat moves. And Naruto could learn some of Link's techniques, like using the bow and arrow more effectively in his own world.
One idea could be a crossover where the characters from Naruto gain the ability to summon dragoons. For example, Naruto could summon a fire - breathing dragoon in battle, adding a new dimension to his combat skills.
One idea could be a crossover where Naruto, with the power of the Kyuubi, somehow ends up in the world of Legend of Korra. He could team up with Korra to face a new threat that combines the dark jutsu from Naruto's world and the bending abilities in Korra's world.
One possible plot idea could be a crossover where characters from Naruto and Legend of Korra have to team up to face the Juubi. Maybe the Avatar from Legend of Korra discovers a new power that is linked to the chakra of the Juubi in the Naruto world.
For Legend of Korra fanfiction, you could write about an alternate universe where the Avatar cycle is broken. Korra has to figure out how to fix it while dealing with the chaos that ensues. You might also consider a story where Korra forms an unexpected alliance with a group of non - benders who have developed their own form of combat to rival bending. Additionally, a fanfic that delves into the relationship between Korra and Asami in more depth, showing their daily lives and how they contribute to the rebuilding of Republic City together, would be really engaging.
Another interesting idea is to create an alternate timeline. Maybe in this fanfiction, the main character makes a different choice at a crucial moment, which completely changes the course of the story. For instance, if Dart had chosen not to pursue the Black Monster at the beginning, how would that have affected his relationships and the world around him? This can lead to a whole new set of adventures and character developments.
In a 'legend of the dragon fanfiction', you might explore the idea of a dragon that is the last of its kind. This dragon has the ability to communicate with other animals and enlists their help to survive in a world that has become hostile to it. The fanfiction could follow the dragon's journey as it tries to find a safe place to live. Along the way, it meets a human who at first is afraid but then realizes the dragon's gentle nature. Together, they form an unlikely alliance to protect the dragon from those who would do it harm, and in the process, change the way their world views dragons.
