In many fanfictions, Naruto shows his protectiveness of Hinata by always being by her side during dangerous situations. For example, when there are enemy attacks, he quickly positions himself in front of Hinata to shield her from harm.
In a certain fanfiction, there was a village-wide competition. During one of the events, another competitor was being too rough with Hinata. Naruto stepped in, warning the competitor to be more careful around Hinata. He then stayed close to Hinata for the rest of the event to make sure she was okay.
The relationship between Naruto and Hinata is a classic case of the strong hero protecting the more gentle and kind - hearted heroine. Their dynamic is very endearing. Naruto's protectiveness in fanfiction heightens the romantic tension between them. It makes readers root for their relationship to develop further, whether it's a slow - burn romance or a more immediate connection. For example, in some fanfics, Naruto's protectiveness is a sign of his unspoken love for Hinata, which is a very sweet and engaging concept.
One example could be a fanfic where during a battle in the Hidden Leaf Village, Naruto immediately stands in front of Hinata when an enemy attacks. He uses his shadow clone jutsu to surround her and keep her safe. His focus is solely on her protection, not even thinking about the battle strategy until he's sure she's out of harm's way.
In some Naruto fanfictions, Hinata could potentially be portrayed as a 'weapon' in a very metaphorical sense. For example, her Byakugan abilities might be exploited in unique ways that make her seem like a strategic weapon for a side or a cause. But in the canon Naruto story, she is a character with her own agency and not really a weapon.
One great source for Naruto and Hinata fanfiction could be FanFiction.net. You can search for stories specifically focused on their relationship there. There are often new and interesting takes on their story, from how they first fell in love to their married life in the future.
Perhaps in the fanfiction, Hinata wears a micro bikini for a special festival in the Hidden Leaf Village. Naruto is really excited to see her in it. They participate in the festival games together and Hinata's new look makes Naruto see her in a different light, more as a strong and confident woman.
One possible plotline could be a story where Naruto has to choose between two versions of Hinata, the original Hinata and a version from an alternate RTN (Road to Ninja) universe. Maybe in this fanfiction, the different Hinatas have unique abilities or personalities that make Naruto's choice more difficult.
One reason could be that he sees Naruto as a younger version of himself in some ways. Both have had their share of loneliness and challenges growing up. Kakashi may want to prevent Naruto from going through the same pain he did. Another reason is Naruto's importance to the village. As the jinchuriki of the Nine - Tails, Naruto is a key asset. Kakashi, being a loyal ninja, wants to protect the village's future which is tied to Naruto.
Well, Naruto has a huge and passionate fan base. People are protective of Naruto fanfiction because it's a way to keep the Naruto universe alive. It allows fans to explore different storylines, relationships, and character developments that they might have imagined while watching or reading the original Naruto. It's like a creative extension of the beloved series.
