Another common theme is Hinata's growth. Many fanfics focus on how she becomes stronger, not just physically but also in terms of her self - confidence, especially with Naruto by her side. For example, she might learn new jutsus or overcome her insecurities.
Love is a very common theme. Since Naruto and Hinata end up together in the original series, fanfics often explore their relationship further, showing their deep love and how they support each other.
Some fanfics focus on the idea of alternate universes. For example, what if Naruto had noticed Hinata's feelings earlier? Or what if Hinata was the one to save Naruto from a difficult situation instead of the other way around? These alternate scenarios allow for different takes on their relationship and add an interesting twist to the traditional Hinata x Naruto story.
Growth is another common theme. Both Naruto and Hinata grow as characters in the original series. In fanfics, their growth as individuals and as a couple is often explored. For instance, Naruto may grow in his role as a leader while Hinata grows in confidence, and these changes impact their relationship.
One common theme is friendship. Just like Naruto values his friends, OCs often form strong bonds with other characters in fanfics. Another theme is self - discovery. OCs usually go through a journey to find out who they are and what their purpose is in the Ninja world. And of course, the theme of power is also prevalent. OCs may strive to become stronger, either to protect their loved ones or to gain recognition in their village.
Power discovery. Since the Uzumaki bloodline is powerful, a common theme is Naruto finding out about his hidden powers. For example, he might discover a new form of chakra control or a special jutsu related to his Uzumaki heritage.
One common theme is family. Since Minato is Naruto's father, many fanfics explore their relationship and how it affects Naruto's growth. Another theme is legacy, like how Minato's actions and reputation influence Naruto's journey as a ninja.
Unity is also a theme. The collar can represent the unity between Naruto and Hinata, not just in their relationship but also in their fight against common enemies. It can be a physical manifestation of their shared goals and the strength they get from each other.
Love and courage are very common themes. Hinata has always been shy, so it takes a lot of courage for her to confess her love to Naruto.
One common theme is power exploration. Since Hinata has this 'futa' aspect, it often leads to exploring new powers and abilities. Another theme is self - discovery. Hinata may go through a journey of understanding this new part of herself.
