A great fanfiction idea could be a story where Korra loses her bending abilities completely and has to learn how to fight and defend the world without them. This would force her to rely more on her wits and leadership skills. Another option is to write about a group of benders who form an underground resistance against a new threat that the official authorities are ignoring. They could have their own unique bending styles and strategies. You could also do a fanfiction where the spirit vines take over Republic City in a more extreme way than in the show, and Korra has to find a way to coexist with them rather than just fighting to control them.
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.
Well, you could write a fanfiction about a new Avatar emerging during Korra's time. This new Avatar could be from a different nation and have a completely different approach to bending and maintaining balance. It would be interesting to see how Korra and this new Avatar interact. Also, a story about the spiritual world becoming more accessible to non - benders could be really cool. Maybe there's a non - bender who discovers a way to enter the spirit world and has to learn how to navigate it without bending abilities. And of course, a fanfiction focusing on the rebuilding of the Air Nomad culture with Korra's help could be full of great story possibilities.
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.
One idea could be a crossover with another popular fantasy world like 'Harry Potter'. Korra could end up at Hogwarts and have to deal with magic in a completely new way. Maybe she'd use her bending to enhance or counter some spells.
One idea could be a crossover with another fantasy world where Korra has to learn new bending techniques from that world's magic users. This would bring a fresh dynamic as she struggles to adapt to different power systems.
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 plot idea could be that your OC discovers a long - lost bending technique. This could attract the attention of both good and bad forces. For example, the Red Lotus might want to use it for their own purposes, while Korra and her friends would try to protect it. Another idea is that your OC is an ambassador from a small, previously unheard - of tribe. They come to Republic City to establish relations, but face many challenges due to cultural differences and political intrigue. Or perhaps your OC has a prophecy about the future of the Avatar world and has to convince everyone, including a skeptical Korra, that it's real.
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.
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 a struggle for power between Korra and the Dark Avatar. Korra, being the Avatar, has to fight against the Dark Avatar's malevolent plans to bring chaos to the world. Another could be a story where the Dark Avatar tries to corrupt Korra, using her insecurities against her.
One idea could be that the reincarnated character has memories of their past life. They could use this knowledge to predict events in the Avatar world. For example, they might know about an upcoming threat and start preparing for it much earlier than anyone else. This could lead to some interesting interactions with Korra and the other characters as they try to convince them of the danger.
