A common theme is the exploration of Hinata's family heritage in relation to her strength. Maybe she discovers some ancient Hyuga techniques or a special bloodline trait that makes her strong. And there's also the theme of female empowerment, as Hinata's journey to strength is a great example of a female character taking control of her own destiny in the Naruto world.
One common theme is Hinata's growth. She goes from being a shy and somewhat underestimated character to a powerful force. Another theme is her relationship with Naruto in the context of her new - found strength. Sometimes it's about how Naruto starts to see her in a new light.
Another common theme is the exploration of their powers in relation to each other. For example, how Hinata's Byakugan and Naruto's Nine - Tails power could be combined in some way during battles or training. Also, the theme of family and legacy, especially as they start their own family, is quite popular in these fanfictions.
One common theme is love and relationship development. Since their relationship in the original series is a significant part of the story, fanfictions often expand on it. They show how their feelings for each other grow over time, from Hinata's initial shy admiration to a deep, mutual love.
The theme of loyalty is quite common too. Hinata has always been loyal to Naruto, and Naruto is loyal to his friends and the village. In fanfictions, this loyalty can be tested in different situations. For instance, when the village is in danger, how do they stay true to each other and their values? And there are also themes related to the ninja world, like exploring new jutsus together or uncovering secrets about the history of the Hidden Leaf Village.
Growth and self - discovery are also typical themes. Hinata might discover new powers or a stronger sense of self. Naruto, too, might learn more about himself through his relationship with Hinata. For instance, he could learn the importance of being more in touch with his emotions, which Hinata helps him with.
One common theme is possessiveness. Yandere Hinata in these fanfictions often wants Naruto all to herself and will go to great lengths to keep others away from him. For example, she might sabotage any potential relationships Naruto could have with other characters.
The theme of adaptation is also quite common. Both Naruto and Hinata need to adapt to the existence of mecha in their world. Hinata might have to overcome her shyness in a more high - tech and dangerous environment, while Naruto has to figure out how to use his brash and bold style in mecha combat. This process of adaptation often leads to character growth in these fanfictions.
Self - discovery is also a frequent theme. Both Naruto and Hinata are complex characters. In crossover fanfictions, they might be placed in unfamiliar settings or situations that force them to re - evaluate who they are. This can be related to their ninja identities, their personal values, or their relationship with each other. For instance, in a crossover with a different ninja world, they may have to adapt and in doing so, learn more about themselves.
One common theme is Hinata's understanding of Naruto's loneliness. Since Naruto has often been alone in his life, Hinata's presence to comfort him fills that void. For example, in many fics, she simply sits and listens to him talk about his problems.
One common theme is redemption. Pain is often depicted as a character who can be redeemed through his interactions with Hinata. For example, Hinata's unwavering belief in the good of people might make Pain question his own actions.
Love and friendship are common themes. Since Naruto and Hinata have a relationship in the series, fanfictions often explore how their relationship develops further, especially in the context of them being at a desk, which could be a place for study or just chatting. Another theme is growth. They both grow as characters, and the fanfictions might show how their time together at the desk contributes to their personal growth as ninjas and as individuals.
