In the 'dark demon naruto fanfiction', Naruto is surely a main character. He is the one who is somehow connected to the dark demon. Besides, there might be other characters like Sasuke. Sasuke could be either an ally trying to help Naruto fight the dark influence of the demon or he could be misled by the demon's power and turn into an antagonist for a while. Another possible main character could be Kakashi. He might be the one to guide Naruto in understanding and dealing with this new threat.
Well, Naruto is the central figure in this fanfiction. However, the dark demon is also like a main 'character' in a sense as it has a huge impact on the story. There may also be new characters created specifically for this fanfiction. For instance, a mysterious sage who knows the secrets of the dark demon and has been waiting for Naruto to emerge. This sage could play a crucial role in helping Naruto come to terms with his situation and find a way to use the power of the demon for good, or at least keep it in check. There could also be characters from Naruto's past who come back in a new form due to the influence of the dark demon, like a resurrected enemy from his early days as a ninja.
Obviously Naruto would be one of the main characters as it's in his name. And probably the dark demon itself, which would have a major role in driving the story.
There could also be some original characters created specifically for this fanfiction. For example, a powerful ninja who has knowledge about the merge process and tries to either help or hinder Naruto. Or perhaps an ancient spirit that was somehow involved in the creation of Dark Naruto in the first place and now has an interest in the merge.
Obviously, Naruto would be one of the main characters, just in his new 'dark lord' role. Sasuke could also be a major character, as his relationship with Naruto is so central in the original series. Their dynamic would likely be very different in this fanfiction, perhaps becoming more of an adversarial relationship.
Since it's a Naruto - based fanfiction, Naruto himself would likely be a main character. There may also be other characters from the original Naruto series like Sasuke, Sakura, or Kakashi who could be involved in his journey as a dark sage.
Naruto, being the protagonist of the original series, would be one of the main characters in 'naruto dark god fanfiction'. His journey would likely be transformed by the presence of the dark god. Sasuke, with his own complex history and power, would also be a mainstay. Then there could be characters like Jiraiya, who might have some knowledge about the dark god from his travels and research. His guidance could be important for Naruto and the others in their fight against this new, dark force.
It really depends on the specific fanfiction. However, it could potentially include Naruto himself, as he is a central character in the Naruto universe. And perhaps some of the main characters from 'Dark Angel' like Max might also be incorporated. There could also be new original characters created by the fanfiction author to bridge the two universes.
The main characters are the Sannin - Orochimaru, Jiraiya, and Tsunade. These three are central to the fanfiction as it explores their characters in a darker context.
There might be a mentor - like figure who has some knowledge about the dark release. This character could be important as they guide the younger or less experienced character with the dark release. Maybe they have a hidden past related to the power as well. In some fanfictions, this mentor could be an old ninja who has seen the power's potential and destruction in the past.
Well, aside from Naruto, Orochimaru could be a main character in this fanfiction. He has always been interested in powerful and dark jutsu. He might be the one who either creates or tries to steal the dark Rasengan for his own evil purposes. And then there's Kakashi. He could be involved as Naruto's mentor, trying to guide him away from the dark path that the dark Rasengan might lead him to.
Obviously, Dark Naruto would be one of the main characters. He is the center of this fanfiction concept. Other than him, characters like Sasuke would likely still play important roles. Sasuke might be either an ally or an adversary to Dark Naruto, depending on how the story is written. Also, characters like Kakashi Sensei could be there to try and guide or stop Dark Naruto, given his new, more dangerous state.
There could be original characters created specifically for this fanfiction. Maybe a mysterious mentor figure who helps Naruto understand and control his 'dark genius' side. This character could have their own backstory and motives that tie into the overall plot.
