Another character could be a new, original character created specifically for the fanfic. This character might be the one who has a special connection to the black fire, like it was passed down in their family. They then get involved in the Naruto universe, interacting with the well - known characters and causing a stir with their black fire abilities.
Another character that could be prominent in 'Naruto Green Fire Fanfiction' is Kakashi. He could play the role of a mentor, guiding Naruto and the others in understanding the new and potentially dangerous green fire. His experience and wisdom would be valuable in dealing with this new element in the ninja world.
Often, Naruto himself can be a main character. He might be exploring the new power of dark fire, either trying to master it for the good of the village or facing the internal struggle of whether to use such a dangerous power. Sasuke could also be a main character. Given his own complex relationship with power and his past, he could be drawn to the allure of dark fire and how it could help him achieve his goals.
Sasuke is also commonly involved. His rivalry with Naruto can be further explored when blue fire is added to the mix. He might try to master the blue fire himself or be in conflict with Naruto over the power it represents.
Sasuke can also be a main character in Naruto Fire Temple fanfictions. His complex personality and his own journey of redemption or power - seeking can intersect with the events at the Fire Temple. Maybe he goes there to find a way to control his new - found powers or to seek answers about his clan's past that are somehow related to the temple.
There could be a whole new set of characters in the 'naruto frozen fire fanfic'. It might be a group of rogue ninjas who have discovered the secret of frozen fire and are using it to their advantage. Or it could be a young apprentice who is learning to control this strange power under the guidance of an old sage. Without reading the actual fanfic, it's all speculation though.
Sasuke can also be a main character in some fanfics. For example, there could be a story where Sasuke finally comes back to the village and Naruto takes him to Ichiraku to have some ramen as a way of welcoming him back. Kakashi might also make an appearance in such fanfics, as he is Naruto's teacher and might join them for a bowl of ramen.
Some fanfics might also feature Naruto himself interacting with a Ryugan user. Naruto could be curious about this new and mysterious eye - power, and they could end up becoming friends or allies.
In some 'naruto yoton fanfic', there are original characters created specifically for the story who possess the Yoton power.

They could be from a long - lost ninja clan that has been hiding their Yoton abilities and now come out into the open due to certain events in the fanfic's plot.
Obviously Naruto is often a main character in 'Naruto Crystal Fanfic' as it is related to the Naruto universe. Sasuke can also be involved, perhaps having a different view on the power of the crystal compared to Naruto.
Sasuke is often a main character in 'eye naruto fanfic'. Since he has the Sharingan, many fanfics explore different aspects of his eye power, like how he might develop it further or use it in new and unexpected ways. Another one is Hinata. With her Byakugan, fanfic writers can create stories about her using it in battles or for some other special purposes, like finding hidden secrets in the ninja world.
