A plot could revolve around a dark force corrupting both Naruto and Hinata. This force might be an ancient evil that has been dormant for years. As Dark Naruto and Dark Hinata, they might target their former friends. Naruto could use his shadow clones in more menacing ways, and Hinata could use her Gentle Fist techniques to cause harm instead of protect. They could form an alliance with other outcasts or villains in the Naruto universe.
There may be some fanfics out there with this disturbing concept, but it goes against the general nature of the Naruto series. One possible plotline could be that Naruto is somehow mind - controlled by an enemy and in that state, he attacks Hinata. But this is really a stretch as Naruto deeply cares for Hinata in the original series.
Perhaps Naruto discovers some dark secrets about the ninja world that make him lose faith in the ideals he once held. He then uses his skills and knowledge to create his own order, ruling with an iron fist as a 'dark master'. He could also form alliances with other anti - hero or villainous characters from the Naruto universe.
There could be a plot where Gaara, as the Kazekage, visits Konoha for some important discussions. Hinata, being part of the Hyuga clan, is involved in some of the events related to the visit. They accidentally cross paths multiple times, and each time, there is a brief moment of connection. Over time, these small moments add up, and they start to seek each other out deliberately. They exchange letters, and through their written words, they learn more about each other's dreams and hopes. This epistolary relationship gradually transforms into a real - life love story as they finally meet face - to - face and realize their feelings for each other are more than just friendship.
One possible plotline could be that Naruto is constantly rejected by the village he is trying to protect. This betrayal and lack of acceptance could gradually turn him dark. For example, if the villagers start to blame him for every bad thing that happens, even when it's not his fault. Another plotline might involve Naruto losing someone very close to him, like Sasuke, in a way that he blames the shinobi world for. This could lead to him deciding to take revenge on the world and turn to darker methods of achieving his goals. Maybe he starts to use forbidden jutsu without hesitation, seeing it as a means to an end.
Maybe they inherit some unique abilities from their Hanyou side. Naruto could gain enhanced speed and Hinata could get some sort of shadow - based power. They then use these powers to face a new, powerful enemy that the regular ninja skills of the village can't handle. This would put them in the spotlight and they would have to prove that being Hanyou is an advantage rather than a curse.
One possible plotline could be that they go on a mission to a far - off land to retrieve a powerful and ancient artifact. Along the way, Hinata's Byakugan helps them detect hidden traps and enemies. Sasuke uses his Sharingan to analyze combat situations quickly, and Naruto with his Nine - Tails chakra provides the brute strength. They face many challenges together and in the process, their teamwork and understanding of each other deepens.
One possible plotline could be that Hinata is under some sort of mind - control. Maybe an enemy uses a jutsu on her that makes her see Naruto as a threat to the village in a false way. So, she kidnaps Naruto to stop him from doing something she believes is harmful. But as the story progresses, Naruto tries to break through to her real self and free her from the mind - control.
One possible plotline could be that Naruto catches Hinata in a compromising situation that seems like cheating, but it's all a misunderstanding. Maybe she was helping a friend in secret and it looked bad. For example, she could be secretly training with another ninja to surprise Naruto with new skills, but he misinterprets it as something more inappropriate.
One possible plotline could be that Batman is tricked into joining the Dark Side. Maybe the Joker uses some elaborate mind - control device or false information to make Batman believe that the Dark Side has the right way to bring true justice to Gotham. For example, he could be made to think that by using more extreme and violent methods, he can finally stop all the crime in the city once and for all.
Perhaps Naruto starts to question his own identity. Since he was abandoned by his family, he could be on a journey to discover his true heritage and in the process, his dark side grows as he faces many hardships and betrayals. He may then use his new understanding to either wreak havoc or find a way to forgive and move forward.
