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.
Well, a cool 'naruto x legend of korra fanfiction' could involve a character exchange. For example, some of Naruto's friends like Sasuke or Sakura could visit the world of Korra and learn about bending. Or vice versa, Korra's friends could come to the ninja world and experience the power of chakra. It would be interesting to see how they interact and how their different skills would complement or clash with each other. They could also exchange fighting styles and learn new techniques from one another.
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.
One idea could be exploring Korra's early training days in more detail. Maybe she has a secret adventure during that time that wasn't shown in the original series. Another could be a fanfiction where Korra has to team up with an unexpected ally from the Spirit World to save Republic City from a new threat. A third idea is to write about what would happen if Korra lost her bending abilities for a while and had to learn to fight and defend without them.
One idea could be that Ichigo, through some sort of interdimensional rift, ends up in the Avatar world of Legend of Korra. He could initially be seen as a threat due to his otherworldly powers. But as the story progresses, he teams up with Korra to fight a common enemy that is trying to take over both their worlds. His Soul Reaper powers could be used in unique ways, like using his Getsuga Tenshou to blast away dark spirits that are plaguing the Avatar world.
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.
An interesting Legend of Korra OC fanfiction idea could involve an OC who was born with the ability to control spirits directly, without the need for Avatar - like mediation. This OC could face challenges as people fear their power. Also, an OC that is a bender who has lost their bending due to some accident and has to find a new way to be useful in the world of bending. Maybe they become a great teacher, teaching non - benders how to defend themselves against benders. And then there could be an OC who is a descendant of an ancient civilization and has access to forgotten bending knowledge.
One idea could be exploring the backstory of a minor character. For example, delving into the early life of a non - bender in Republic City and how they coped with living in a world where benders had more influence. Another idea is to create an alternate timeline where Korra fails to restore the balance and how the world descends into chaos as a result. Or perhaps a fanfiction centered around a new romance between two characters that were not paired in the original series.
For a Legend of Korra crossover fanfiction, a crossover with the Star Wars universe would be cool. Korra could be on a planet in the Star Wars galaxy and interact with Jedi and Sith. Her bending could be seen as a new form of 'Force - like' power. She might get involved in the struggle between the light and dark side. Also, a crossover with the world of Studio Ghibli. Korra could find herself in the beautiful and magical worlds created by Miyazaki, like in Spirited Away. She could use her bending to solve the problems in those unique settings.
One idea could be exploring Korra's life after she restores balance. Maybe she travels the world teaching the new generation about bending. Another could be a story where she has to face a new, unknown threat that challenges her in different ways than before.
