In fanfiction, Naruto's Uzumaki bloodline often gives him enhanced chakra reserves. This allows him to perform more powerful jutsu for longer periods. For example, he can spam his Rasengan more frequently without getting exhausted quickly.
One possible plot could be that Naruto and Naruko (assuming it's an alternate universe where there's a female version of Naruto) discover a new and powerful bloodline ability within their Uzumaki lineage. They might have to train together to master it and then use it to protect the village from a new threat. Maybe it's a bloodline ability that allows them to manipulate time on a small scale, like slowing down an enemy's attack.
The Uzumaki bloodline can also affect his relationships with characters from other villages. In fanfiction, ninja from other villages who know about the Uzumaki's power might either fear or respect Naruto more. This could lead to different diplomatic situations. For example, a village might be more willing to negotiate with the Hidden Leaf because of Naruto's Uzumaki bloodline. On the personal level, he might meet other Uzumaki descendants in other villages, and they could form a strong bond based on their shared bloodline.
In the fanfiction, Naruto and Naruko could start off as strangers who are brought together by the mystery of their Uzumaki bloodline. They might be curious about each other's abilities and start to train together. During this process, they would have small arguments because of their different ways of using the bloodline powers. However, these arguments would actually make them understand each other better. As time passes, they become closer and closer, and the relationship develops from acquaintances to friends, and finally, lovers. Their Uzumaki bloodline would be like a thread that ties them together throughout the development of their relationship.
The Legend of Uzumaki Hiroto was a derivative work of Naruto, which told the story of Uzumaki Hiroto's growth and the stories of other characters. Uzumaki Boto Legend was different from the original Naruto Naruto Shimbun Legend, so it was considered an independent manga.
It depends on the specific plot of the fanfic. Sometimes he could be on a secret mission, in a hidden village, or facing a new challenge in an unknown location.
Well, he could start a family with Hinata and have lots of kids, passing on his Uzumaki bloodline. Then, he could encourage his friends who have some Uzumaki connection, like Karin, to also have families and pass on their Uzumaki genes. He could also set up a school or training center in the Uzumaki land, teaching the Uzumaki ways of life and ninjutsu, which would attract orphans or those who want to be part of the Uzumaki clan.
One possible plot is that Naruko discovers her vampire bloodline after an encounter with a powerful and ancient vampire. This newfound heritage causes chaos in her life as she is both feared and desired by different factions. Some might want to use her power for evil, while others see her as a key to a greater good. She has to navigate this complex web of relationships while coming to terms with what she is.
They are not appropriate. The Naruto series is known for its action, adventure, and positive themes. Lemon fanfics that may contain sexual or explicit content are not in harmony with the family - friendly nature of the original Naruto work. It's better to focus on fanfics that respect the original themes and values of the series.
A really interesting plot could be Naruto traveling back in time to the era before he was born. He could meet his parents and other important figures in the village's history. This would give him a chance to understand the roots of the village better and also learn some new jutsu or strategies that he could bring back to his own time to make the Hidden Leaf even stronger as a Hokage.
