Another plot could be a training - exchange plot. Korra, being a more head - strong bender, could learn from Aang's more spiritual approach to bending. And Aang, in turn, could learn from Korra's more direct and physical combat style. This could lead to some really cool battles and growth for both characters within the fanfiction.
One interesting plot could be a time - traveling scenario where Aang and Korra meet in a different era. They might have to team up to face a new threat that combines the challenges of both their times. For example, an ancient spirit that was sealed away during Aang's time is accidentally released in Korra's era, and they need to use their unique bending skills and knowledge to reseal it.
It's really hard to say. Aang was a very powerful Airbender and the Avatar. He had the advantage of being able to enter the Avatar State more easily due to his spiritual connection. However, Korra was a very physical and aggressive fighter. She had mastered all four elements and was not afraid to take on tough opponents head - on. In a fight, it could depend on the circumstances, like the location and whether they have any outside help.
I'm not really into that kind of fanfiction. However, some popular fanfiction platforms like Archive of Our Own might have such stories. You can search there using the tags 'korra' and 'aang' to find relevant works.
The theme of friendship and mentorship also pops up a lot. Even though they are from different eras, they can still form a bond. Aang can act as a mentor to Korra, guiding her through spiritual challenges that he has already faced. And Korra can show Aang how the world has changed and how she is adapting to new threats in a different time.
One great aang and korra fanfiction is 'The Avatar's Bond'. It beautifully explores the relationship between Aang and Korra across different timelines. They face challenges together and learn from each other's experiences as Avatars.
One interesting plot could be Aang's struggle to rebuild the Air Nomad culture. He might face challenges like finding suitable places for new air temples and recruiting new airbenders. Another plot could involve his relationship with Katara after the war, how they adjust to a more peaceful life together. And perhaps there could be a plot where Aang has to deal with remnants of the Fire Nation who are still bitter about the war's outcome.
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.
If Korra meets Aang in fanfiction, they may have a deep conversation about the role of the Avatar. Aang could share his story of how he had to end the Hundred Years War and the toll it took on him. Korra could then talk about her struggles in the modern world with things like industrialization affecting the balance of the elements. This exchange would be really interesting as they compare and contrast their Avatar journeys.
One interesting plot could be Aang and Katara exploring a new, hidden air temple together. They might discover ancient airbending techniques and secrets that help Aang further his mastery of airbending.
Maybe in the fanfiction, Aang goes back in time and meets his past self. He then has to guide his younger self without disrupting the timeline too much. This could lead to some really cool moments of self - discovery for Aang, as he sees himself from an outside perspective and realizes how much he has grown.
One interesting plot could be a competition between them for a powerful magical artifact. Percy uses his water - based powers, Jason his lightning and flight, and Nico his control over the dead to outwit each other in a race to find it.
