The dark races leader in the fanfiction could be from a race that has been misunderstood. Naruto, being the empathetic character he is, tries to bridge the gap between the dark race and the rest of the ninja world. In the harem aspect, this could lead to a situation where the leader of the dark race, along with some of Naruto's existing female friends, form a sort of alliance. They all start to rely on Naruto in different ways, and a harem - like dynamic develops as they all grow closer to him.
In this fanfiction, the dark races leader might have a tragic past that Naruto tries to heal. As he does so, the leader starts to fall for him. In the context of a harem, the other female characters could be initially suspicious of the dark races leader. But as they see Naruto's positive influence on her, they might start to accept her. This could lead to a complex web of relationships where Naruto is at the center, trying to balance the different emotions and needs of all the women in his life.
One idea could be Naruto using his unique skills and values to reform the League of Shadows. He might introduce a new code of honor that focuses on protecting the weak rather than just causing chaos. His Rasengan could be modified into a more stealthy and strategic attack for the League's operations.
Sakura could be in Naruto's harem. In the original series, she had a long - standing relationship with Naruto. In this fanfiction, with Naruto being 'dark godlike', she might be drawn to his new power and the mystery surrounding him. Also, Hinata would be a likely candidate. Her long - held feelings for Naruto could intensify with his new status, and she would be part of his harem due to her loyalty and love for him.
Often, 'dark naruto' in this type of fanfiction could have a more complex set of motives. He may not be as straightforward as the original Naruto. His relationships within the harem might be filled with power dynamics, where he uses his newfound 'dark' qualities to either protect or control the characters in the harem. It could also mean that his moral compass is a bit skewed, leading to more morally ambiguous decisions.
Often, Naruto himself in his 'dark' form is a central character. Hinata might be a part of the harem as she has strong feelings for Naruto in the original series. Sakura could also be included, perhaps with a different take on her relationship with Dark Naruto. And then there could be some original characters created specifically for the fanfiction to add more variety to the harem.
One idea could be that Naruto characters are transported into the Dark Souls 3 world. For example, Naruto with his high energy and determination could be seen as a sort of chosen undead. He might use his shadow clones in a unique way to fight the various demons and bosses in the game world. His chakra could be translated into a form of 'soul energy' in the Dark Souls 3 context.
Sakura could be in the harem. She has always had a connection with Naruto, and his new godlike status might make her see him in a different light. Hinata is also a likely candidate, as she has always been in love with Naruto. And perhaps some new female characters could be introduced, like a powerful kunoichi from a far - off land who is drawn to Naruto's power.
Well, a plot might be that Dark Naruto in the fanfiction is on a journey to change the ninja world with his harem by his side. They could be facing off against the established shinobi villages' old ways. For example, they might try to create a new system where power is more equally distributed among all ninjas, not just the elite families. And the harem members could each have special skills that contribute to this goal.
In many 'dark naruto harem' fanfictions, Naruto's growth as a character is a central plot. His journey from being an outcast or having a difficult start to becoming a powerful figure is explored.
