In the 'naruto everyone has darkness' fanfic, Naruto and Sasuke are probably the main focus. Naruto, who always tries to be the hero, might have a side of him that is full of self - doubt and anger due to his past. Sasuke, on the other hand, is already quite dark with his vengeance - driven motives. Additionally, characters like Sakura could also be important. She has her own insecurities and jealousies that could be explored as part of her 'darkness'. And then there's Itachi, whose actions were clouded by a complex set of reasons that could be delved into deeper in this fanfic.
Most likely Naruto and Sasuke would be main characters as they are central in the original Naruto series and their stories can be easily explored in terms of having a 'dark side'.
I think Naruto would be one of the main characters. Given his backstory of being an outcast as a child, there's a lot of potential for exploring his darker emotions. Also, Sasuke, with his quest for revenge, is a prime candidate. And perhaps Kakashi as well, considering his past traumas and the secrets he holds. These characters have complex personalities that can be further developed in the context of this fanfic to show their darkness.
This fanfic could be about uncovering the hidden and often repressed aspects of the Naruto characters. It might explore how the shinobi world, with its constant wars and power struggles, has affected everyone in different ways, leading to the presence of darkness in all. It could also look at how characters deal with this darkness - some might struggle against it, while others might be more in tune with it. There could be interesting character developments as they face their own and others' darkness throughout the story.
It might focus on Naruto and an antagonist who is deeply entrenched in the darkness. This antagonist could be a new character or an existing one from the Naruto series who has turned to the dark side. Other main characters could be the members of Naruto's team, who support him in his journey to understand and combat the darkness. They could provide different perspectives on how to deal with the dark elements in the story.
Since I haven't read it, I can't say for sure. But it could feature Naruto as a main character, as he is often central in many 'Naruto' fanfics. He might be the one guiding or inspiring the character who is rising from the darkness. Or it could be an original character created specifically for this fanfic who is on their own journey of self - discovery and redemption.
It might explore how each character in Naruto, despite their heroic or villainous facades, has an inner darkness. For example, Naruto himself, who is usually seen as a bright and determined hero, may have a hidden side of self - doubt and fear of being alone again. This fanfiction could dig deep into the psychological aspects of the characters, showing that no one is truly pure of heart and that everyone has to battle their own internal demons.
It's difficult to say without reading the 'a taste of darkness fanfic'. However, it's common for fanfics to either focus on the original protagonists and give them new challenges related to the darkness theme, or introduce new characters that are embodiments of the darkness. For instance, if it's a fanfic based on a superhero story, the main characters could be the superhero facing a new, more menacing villain who represents pure darkness, or it could be about the superhero's sidekick who gets lured into the dark side and becomes a central character in this darker narrative.
Often, there is a brave hero or heroine who stands against the darkness. They might be an ordinary person at first but discovers they have some special power or ability.
There might be a character who is an expert in a particular field relevant to survival, like a former military person with combat and survival training. And there could also be a more vulnerable character, perhaps a young person or someone with a disability, who the group has to protect. This would add an extra layer of complexity to the story and the relationships between the characters.
Obviously, Naruto would be one of the main characters since he has the Omnitrix. But we could also expect to see his usual friends like Sasuke and Sakura. They would be involved as Naruto uses his new powers. And perhaps some of the alien forms from the Omnitrix could be considered 'characters' in a way, as they would influence Naruto's actions and decisions.
Well, Naruto is surely a main character. And depending on the plot, characters like Kakashi could be important. He's Naruto's teacher and might try to guide Naruto away from the allure of darkness. Also, Orochimaru could be a key figure. He's always been associated with dark arts in the Naruto series, and in this fanfiction, he might play a role in Naruto's exploration of the darkness, either as an ally or an enemy.
The main characters would surely include Naruto. Then, depending on the direction of the fanfiction, characters like Jiraiya could be important as he might be the one to help Naruto understand and control his dark side. There could also be some dark - themed characters that are part of Naruto's heritage or the source of his 'son of darkness' status. And of course, his friends, even if they are initially wary of him, would still be key characters as they react to Naruto's transformation or discovery of his new identity.
