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.
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.
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.
In addition to Harry, there could be other important characters such as Sinestro. Sinestro could initially be an antagonist, seeing Harry as an outsider in the Green Lantern world and trying to undermine him. But as the story progresses, their relationship could become more complex. There might also be the Guardians of the Universe who play a role in guiding Harry in his new role as a Green Lantern.
I'm not entirely sure as it depends on the specific fanfiction. But it could be the main characters from the original work around which the fanfiction is based.
Obviously, Bella, Edward, and Jacob are likely to be main characters as they are central to the original Twilight story. Their relationships are so complex and full of drama that fanfiction writers often like to explore them further.
The main characters can include the gunsmith, who might be an outsider to the traditional ninja world but has a unique skill set. Another could be a ninja who becomes the gunsmith's protector or partner. For example, Sasuke could be interested in these new firearms as a way to enhance his own power. And sometimes, there are original characters created specifically for the fanfiction, like a rival gunsmith who tries to outdo the main gunsmith in creating the most powerful weapons.
Often, there are also antagonist assassins who are main characters in a sense. They drive the plot by creating conflict. These assassins could have their own motives, like working for a powerful and shadowy organization. Their backstories, which might include things like being orphans trained from a young age to be killers, can add depth to the fanfiction.
Naruto himself could be a main character in such fanfiction. Maybe he gets framed for pickpocketing and has to clear his name while also dealing with the real pickpocket who is causing chaos in the village.
