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 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.
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 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.
The theme of legacy also often appears. Hinata comes from the Hyuga clan and Naruto has his own heroic legacy. Fanfics may explore how these legacies combine and influence Bolt's path. For example, Bolt might inherit certain powers or a sense of duty from both his parents, and the fanfic will show how he grapples with and grows from that.
The theme of family also appears often. As they start their own family, fanfics may focus on how they raise their children, pass on their values, and how their family interacts with the rest of the Hidden Leaf Village. There are fanfics that show Naruto and Hinata teaching their kids about the importance of hard work, friendship, and loyalty, just as they learned in their own lives.
Love and sacrifice are common. Naruto's death for Hinata would be the ultimate act of love. Another theme could be grief. Hinata would have to deal with the intense grief of losing Naruto. And also, heroism. Naruto's act of dying could be seen as a heroic one in the context of protecting Hinata or something she holds dear.
One common theme is probably the exploration of their new relationship. Since they are on their honeymoon, it's a time for them to get to know each other in a more intimate way.
Character growth is also prevalent. As Naruto and Hinata navigate their relationships in the harem, they often grow as characters. They learn more about themselves, their feelings, and how to handle different situations. In many fanfics, Naruto becomes more in touch with his emotions, and Hinata becomes more confident.
