A third storyline could be a fusion of the two worlds. A powerful villain finds a way to merge the two universes and chaos ensues. Yugo and Korra must then gather a group of heroes from both worlds, including their friends, to stop this villain and separate the worlds again. They would have to overcome differences in culture, power systems, and beliefs to succeed.
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.
Another storyline could involve a character from The Legend of Korra traveling to Yugo's world. For example, Bolin could end up there and be amazed by the different magic and creatures. He and Yugo could form an unlikely friendship and learn from each other's skills. Yugo could teach Bolin about the Wakfu energy, and Bolin could show Yugo how to use earthbending in unique ways.
Yugo could fit in as a unique foreigner. His Wakfu - based powers would be a new and strange concept in the Legend of Korra world. He might initially be seen as a threat because of his unfamiliar powers, but as he shows his good intentions, he could be accepted. For example, he could use his powers to help Korra in her fight against the Equalists, as his abilities could provide an unexpected advantage against their technology - based attacks.
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.
In a 'Korra meets Aang' fanfiction, a storyline could be that Korra is having trouble with her connection to the past Avatars. Aang then comes to her as a sort of mentor, guiding her through the process of strengthening that connection. They could also face a common enemy that is trying to sever the Avatar's connection to the past altogether, which would force them to fight side by side and use their combined powers and knowledge to overcome the threat.
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.
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 good experience could be finding fanfictions that expand on the relationships between the characters. For example, those that explore the friendship between Korra and Asami in more depth. It gives a new perspective on their bond.
