A descendant of a long - forgotten fire - bending clan that was known for their black fire abilities could be the main character. This character might have grown up not knowing about their special heritage until certain events unfold that awaken their black fire powers.
One idea could be exploring the origin of the black fire in the 'Legend of Korra' universe. Maybe it was a long - lost form of bending that was once used for evil but could be redeemed. Another could be a story where a new character discovers they have the ability to control black fire and must learn to master it while facing discrimination from other benders.
Obviously Naruto and Korra could be main characters. Naruto with his experience with the tailed beasts would be crucial in dealing with the Juubi. Korra, as the Avatar, has the power to bend all four elements and could use her abilities in new and creative ways to fight against the Juubi.
The main character is Korra, of course. She's the one with all the bending powers and the responsibility of the Avatar. But it's not just her. Her friends play important roles too. Mako, the strong - willed firebender, and Bolin, the fun - loving earthbender, are likely to be main characters. Asami, the intelligent and resourceful non - bender, also has a big part to play. She brings a different perspective to the group with her knowledge of technology and business. And there may be other characters from the 'The Legend of Korra' universe that are central to the story in the graphic novel, like Tenzin, Korra's airbending teacher, who could also have a significant role in guiding Korra or being involved in the overall plot.
Korra is surely one of the main characters. She is the Avatar after all.
Korra is the main character. She's the Avatar, a powerful being with the ability to bend all four elements. Asami is also a main character. She's a non - bender but is very intelligent and a great inventor. Mako and Bolin are brothers. Mako is a firebender and Bolin is an earthbender, and they are important characters in Korra's journey.
It could be a new character entirely, someone created by the fanfic writer. This character could be an orphan who has a deep connection with Pokemon from a young age.
It could be a group of rogue ninjas from Naruto's world who have found a way to cross over to Korra's world and cause chaos. They might want to steal the bending abilities for their own evil purposes.
Well, it could be certain political rivals. Maybe there are those who fear that the child of Korra and Iroh will have a strong claim to leadership or influence in the future. So, they become the antagonists, trying to create problems for the couple during the pregnancy. It could also be some dark spirits or entities that sense the special nature of the unborn child and want to prevent it from being born, seeing it as a potential obstacle to their own dark purposes.
Hermione could be a great main character. She's smart and curious, so if she ended up in the Wings of Fire world, she would be eager to learn about the dragons and their society. She could use her knowledge of magic from Harry Potter to interact with the new world and might even try to find a way to combine the two magics.
One way could be through a powerful spiritual ritual. Maybe there's a long - forgotten temple where the spirits are in a state of imbalance. A character from another world or dimension accidentally stumbles upon this place and through some strange energy transfer, they are reincarnated into the Legend of Korra world. The spirits could be trying to correct an old wrong or bring in a new element to help the world, and this character is the key.
