Family is a very common theme. Since it's about Naruto being married, there are often stories about building a family, raising children, and passing on the ninja way to the next generation. For example, in many fics, Naruto and his partner teach their kids about the importance of friendship and hard work.
Another theme is the continuation of Naruto's journey. Even though he's married, his adventures don't stop. He might go on missions with his spouse or protect the village from new threats. This shows that marriage doesn't mean the end of his growth as a ninja. In some fics, his marriage actually makes him stronger and more determined.
Love against all odds is also a prevalent theme. Apollo's status as a god might bring many obstacles to his marriage. But in fanfic, love often conquers all. There could be stories where he has to fight other gods or face the wrath of Zeus to protect his marriage. This shows the power of love in the face of great challenges.
One common theme could be love and commitment. Since it's about sakura being married, the story might focus on how she and her partner maintain their love and commitment to each other. Another theme could be family. It could explore how sakura builds a family with her spouse, including having children or dealing with in - laws.
Since I don't know the exact nature of 'chomi', it's hard to say. But in general, married - related fanfics often explore themes like relationship growth, family life, and dealing with in - laws.
One common theme could be redemption. Maybe the banished character has to go through a journey to prove themselves worthy again, especially in the context of their marriage. Another theme might be the struggle against the stigma of being banished while trying to maintain a relationship.
Power dynamics is also a big theme. When Naruto marries a character from another universe, their powers might complement or conflict with each other. They could learn from each other's power - using techniques and grow stronger together.
Another theme is the exploration of love and relationships. Since they come from different backgrounds, the fanfictions usually depict how they learn to understand and love each other. It could involve them learning about each other's likes and dislikes, and growing closer over time. For example, Naruto might introduce Lightning to his love for ramen, and Lightning might share her knowledge of her village's unique fighting techniques with Naruto.
Often, there is a theme of discovery. Since they are from different universes, the fanfiction may focus on how Naruto and Bulma discover each other's worlds. There could also be a theme of acceptance. They have to accept each other's differences, like Naruto's use of chakra and Bulma's use of Capsule Corp technology. And of course, love is a central theme as they are getting married in these fanfictions.
Well, a frequent theme is the integration of their different backgrounds. Ryuzetsu being from a certain group and Naruto from Konoha. Their marriage often involves dealing with cultural differences between their respective groups. Also, there's the theme of power - how their combined power affects the balance in the ninja world. It can be really interesting to see how different writers handle these themes in their fanfictions.
One common theme is redemption. Naruto, despite being banished, often finds a way to prove himself worthy through his new married life. Another theme is new beginnings. He leaves behind the troubles in Konoha and starts fresh with his partner. For example, in many such fanfictions, he learns new skills or ways of life from his new village or his spouse.
One common theme is family. Often, the fanfictions explore them starting a family, having children, and the joys and challenges that come with it.
