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.
One of the main themes is love. Not just the mother - son love between Naruto and Kushina, but also how Kushina's love for Naruto can be a driving force in the story. For instance, in some fanfics, Kushina's love gives Naruto the strength to overcome great challenges. Also, the theme of sacrifice is common. Kushina sacrificed herself for Naruto, and fanfics often expand on this idea, showing how Naruto honors her sacrifice and what it means for his character development. In addition, there's often a theme of discovery, where Naruto discovers more about his mother and his own identity as an Uzumaki.
One interesting fanfiction could be about Mit Uzumaki and Naruto Uzumaki teaming up to face a new, powerful enemy that the Hidden Leaf Village has never seen before. They could combine their unique skills and family powers to protect the village.
In many fanfictions, Naruto might obtain the Uzumaki sword through a hidden inheritance. Maybe it was left behind by an ancient Uzumaki clan member and Naruto discovers it in a secret location, like an old, forgotten Uzumaki shrine.
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.
I recommend the following two novels that describe the dark side of Uzumaki Naruto: 1. " The Darkness of the Heavens Begins from Naruto." This novel told the story of Naruto Uzumaki's dark side after crossing the Naruto World and fighting against other villains. 2. Naruto: The Ominous One also featured Naruto Uzumaki as the main character. It described the story of his struggle against other villains after he turned dark. These two novels are relatively long works. I hope you will like them.
Naruto Uzumaki in fanfiction often has different portrayals. Young Naruto in fanfictions can be shown in various new adventures. Writers might explore his growth in unique ways, like making him face challenges that were not in the original story. This allows fans to see different aspects of his character and how he could have developed under different circumstances.
There's also 'Naruto: The Uzumaki - Uchiha Alliance'. In this fanfic, Naruto forms an alliance between the Uzumaki and Uchiha remnants early on in his journey. It shows how this alliance changes the dynamics of the Naruto universe. There are some really interesting relationships that develop between the characters, and it's a great read for fans who want to see a different take on Naruto's story.
