One common theme is the bond between father and son. Naruto's journey of getting to know and care for baby Boruto is often explored.
Another theme is the passing on of the ninja way. Since Naruto is a great ninja, many fanfics show him teaching Boruto about the values and skills related to being a ninja from a very young age. For example, things like perseverance, loyalty, and how to use chakra properly. It also shows how Naruto wants to make sure Boruto grows up to be a great ninja and a good person.
The theme of family also extends to include Hinata. Many fanfics in this genre show the family unit of Naruto, Hinata and Boruto. How they support each other, and how Hinata helps Naruto in raising Boruto. It gives a more complete picture of the family life that was not fully explored in the original series at the time when Boruto was a baby.
Another theme is his potential as a ninja even as a baby. Fanfics often explore how his natural talents start to show early on, like his strong will and determination that are already evident in his infancy. They might also show how some of the villagers start to notice these things. For example, in some fanfics, an old ninja might see Naruto's determination when he tries to crawl towards something and realizes he has the makings of a great ninja.
Growth and potential. These fanfics usually show baby Sasuke having some signs of his future great power, like early hints of his Sharingan abilities. It's about his journey from being a baby with potential to the great ninja he will become. Well, in a lot of these fanfics, the relationship between Sasuke and Naruto also gets an interesting start. Maybe they meet as babies or toddlers, and there's some sort of connection or foreshadowing of their future rivalry and friendship.
Often, there's a theme of friendship and cooperation. In crossovers like Boruto with the Attack on Titan world, Boruto and his friends have to work together with the characters from that world, like the Survey Corps. They learn from each other and grow stronger together. Also, a sense of discovery is common. Boruto and his team are often in a new world they don't understand, and they have to figure things out, which makes for an interesting read.
One common theme is protection. Naruto is always there to protect baby Naruko from harm. Another theme could be family or a sense of kinship. Even though they may not be related in the traditional sense in the original story, in the fanfic, Naruto takes on a role like an older brother or a father figure. Also, the theme of heroism is prominent as Naruto is the hero who saves the day.
One common theme is redemption. Since Naruto travels back in time, he often tries to redeem the actions of others or make up for his own past mistakes. For example, he might try to save characters who met a tragic end in the original timeline.
One common reason is envy. Naruto is so highly respected and has achieved so much. Boruto, in fanfic, might envy that and turn it into hatred. Another is the generational gap. Their values and ways of doing things could be different, leading to conflict and hatred in fan - made stories.
One common theme is character development within the harem dynamic. Writers often explore how Boruto interacts with different characters in the harem, showing his growth as a person and a ninja. Another theme could be the relationships between the harem members themselves, like how they deal with jealousy or form friendships. Also, adventure themes can be incorporated, where the harem and Boruto go on quests together and face challenges as a group.

Well, sometimes the theme of family is explored in depth. We see how the new generation is influenced by their families. For instance, Mitsuki's relationship with Orochimaru and how that shapes his actions and decisions. Also, the theme of hope in a world that has already been through so much chaos. The characters in these fanfics often strive to bring about positive change in their world, whether it's through political means or by simply being strong enough to protect their loved ones.
Friendship is a very common theme. Boruto and Mitsuki have a deep bond that is often explored in these fanfics. Another theme is growth. They both grow as ninjas and as individuals, and this is shown through their experiences together. Also, loyalty is often depicted, like Mitsuki's loyalty to Boruto.
