Another great storyline could be about a character from Naruto ending up in the world of The Legend of Korra and having to adapt. Maybe Sasuke somehow gets transported there and has to learn about the new bending techniques and how to fit into this different society. He could end up sharing his ninja skills with the benders and creating a whole new form of combat.
Well, in some fanfictions, there are storylines centered around Korra's relationships. Maybe she falls in love with a non - bender, which causes a stir in the bending community. Or perhaps she has to repair a broken friendship with one of her old allies. Also, a great storyline could be Korra having to deal with the political unrest in the Avatar world. She could be in the middle of a power struggle between different nations, trying to bring peace through her avatar powers.
A great storyline might be a pre - Korra story in the Legend of Korra world but with a Star Wars - like epic space battle feel. Imagine the Water Tribes having a large - scale naval battle against an invading force, with ships and strategies inspired by Star Wars, but with the unique bending abilities of the Avatar world thrown into the mix.
One possible storyline could be Yugo getting transported into the world of The Legend of Korra. He might struggle to understand the new bending powers and the complex political situation in that world. Maybe he teams up with Korra to fight against a new threat that is using some sort of dark magic similar to what he has faced in his own world.
Some fanfictions focus on Naruto having a different upbringing. For instance, if he was raised by a different clan, like the Hyuga. This would give him access to their unique abilities and fighting styles. He could also have a different set of friends and rivals, which would completely reshape his character development and the overall plot of the story.
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.
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.
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 possible storyline could be about how they prepare for the new arrival. They might have to adjust their living situation, like finding a bigger place to live. Maybe Korra is worried about how being a mother will affect her role as the Avatar. And Mako could be thinking about how to provide for the family while still being involved in the city's affairs.
