A possible plot in this fanfiction could be that Dark Naruto and Dark Kyuubi discover a hidden realm that is filled with dark energy. They decide to make this realm their base and start recruiting other dark - minded characters from the Naruto universe. As they grow in power, they start to spread their dark influence across different ninja villages. However, a group of ninja from all the villages join forces to stop them. This group includes some of Naruto's old friends who believe that there is still some good left in him and are determined to save him from the darkness.
One plot idea could be that Dark Naruto forms an alliance with Dark Kyuubi to take over the Hidden Leaf Village. They use their combined dark powers to manipulate the villagers and turn them against each other. Another idea is that they embark on a journey to find a powerful, ancient artifact that can enhance their dark abilities even further. Maybe they face off against the original Naruto and Kyuubi in a final battle of good versus evil.
Well, a plot could involve Dark Naruto being corrupted by the Dark Kyuubi's influence. The Dark Kyuubi might convince Naruto that the village has always been against him and that he should use his newfound dark powers to seek revenge. This could lead to a series of battles within the village as Naruto tries to assert his dominance. Also, there could be a sub - plot where some of Naruto's friends try to bring him back to the light side by appealing to his past memories and relationships.
One idea could be Dark Naruto forming an uneasy alliance with the Kyuubi. They might decide to take on the Hidden Leaf Village together, believing it has wronged Naruto in some way. Naruto could use the Kyuubi's power in a more sinister way than ever before.
Perhaps they are living in a parallel universe where everything is dark and gloomy. Dark Naruto and Dark Kushina could be trying to find a way to break through to the normal universe. They might encounter strange versions of their friends and foes, and have to battle their own inner demons along the way. For example, Dark Naruto might struggle with the darker aspects of the Nine - Tails' power that he has fully embraced in this universe.
One plot idea could be that Dark Naruto, with his newfound power and darker nature, crosses paths with Anko. Anko, being a strong and somewhat mysterious character herself, could initially be on a mission to stop Dark Naruto. But as the story progresses, she realizes there's more to his transformation than just evil. She might try to understand the root cause of his darkness, perhaps related to the village's treatment of Naruto in the past. This could lead to an alliance between them against a common enemy within the village who wants to keep Naruto's power in check at any cost.
Well, perhaps they form a secret society within Hogwarts that promotes dark magic. They recruit students who feel left out or who have a thirst for more power. Dark Hermione could use her knowledge of spells and Dark Fleur her charm and allure to draw in followers. And then there could be a conflict when the other students and teachers start to suspect something and try to stop them.
One plot idea could be a story where in a dark alternate universe, Hinata is forced to become a spy against Naruto. She struggles with her loyalty to her village and her feelings for Naruto. Another could be that a dark force corrupts Hinata's mind, making her see Naruto as an enemy, and Naruto has to find a way to break the spell.
One idea could be a Naruto - style character being trained in the ways of the Dark Jedi. Maybe Naruto discovers an ancient Sith artifact in the Naruto world that gives him access to Dark Side powers, like enhanced chakra manipulation with a dark twist.
One idea could be that Dark Naruto has to face his inner demons while Naruko tries to save him. Maybe there's a villain who is trying to manipulate Dark Naruto's power for evil purposes and Naruko discovers this and has to fight both the villain and convince Dark Naruto to resist the dark influence.
One idea could be exploring Dark Naruto's internal struggle. Maybe he's constantly fighting against the dark chakra within him and how that affects his relationships with the other characters in the Naruto universe. He could be on a journey to find a way to control or purge the darkness without losing his identity.
One plot idea could be that Dark Naruto, who has been influenced by some dark force, sees Ino as a key to unlocking a hidden power within himself. Ino, on the other hand, tries to use her mind - related jutsu to understand what's wrong with Naruto and ends up getting caught in his dark world. She has to fight against his darker impulses while also trying to save him from whatever is corrupting him.
One plot idea could be that Dark Naruto, with his inner turmoil, meets Fuu and they form an unlikely alliance to fight a common enemy in the ninja world. Maybe a powerful and dark force that threatens both their homes or ideals.
