Characters from the spirit world, such as Raava and Vaatu, might also be popular in Korra Dark Avatar fanfiction. Since the concept of the Dark Avatar is closely related to the balance between light and dark in the spirit world, these spirit entities can be used to drive the story forward, either as allies or foes of the Dark Avatar.
The origin of the Dark Avatar in fanfiction can also be very captivating. It could be a result of a corrupted spirit world influence, or perhaps a dark ritual gone wrong. Exploring how this new Dark Avatar came to be can add depth to the story and explain their motives and actions.
The relationship could be shown as a mentorship of sorts in fanfiction. The Dark Avatar, having a different perspective on power and the spirit world, could teach Korra things she never knew. At the same time, Korra could try to reform the Dark Avatar. It would be a complex relationship full of give - and - take, with both characters growing in different ways. For example, the Dark Avatar might learn about compassion from Korra, while Korra could learn about the hidden aspects of the spirit world from the Dark Avatar.
I've heard of a fanfic where Dark Avatar Korra is on a journey to restore balance in a world that has turned against the Avatar. It's a great read as it shows her using her unique powers in creative ways. The author really captures her new, edgier personality.
Korra is definitely one of the main characters. She is the Avatar and her journey is central to the story. Asami is also important. Their friendship and the things they do together play a big role in the graphic novel.
One interesting Dark Avatar Korra fanfiction could be one where she uses her newfound 'dark' powers to fight against an ancient evil that the normal Avatar powers couldn't handle. It might show a different side of her character, more ruthless yet still with a sense of justice.
Jake Sully is often a popular character in fanfiction. Writers like to explore his journey further, such as his time adjusting to life as an avatar before the events of the movie. Another popular one is Neytiri. Fanfic writers might write about her training as a warrior in more detail or create scenarios where she has to make difficult decisions without Jake's help.
Asami could be a key character in many crossovers. Her engineering skills could be valuable in different settings. For instance, in a crossover with a steampunk world, Asami could collaborate with the local inventors, using her knowledge to upgrade their machines and also learn from their technology while still being able to use her martial arts skills when needed.
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.
Korra is surely one of the main characters as it's in her name. Also, Mako and Bolin, her friends from the series, might be important characters in the light novel too.
I think Mako and Bolin could be main characters too. They are Korra's friends and often accompany her in her adventures. Mako is a firebender and Bolin is an earthbender, and they bring different skills and personalities to the story.
