This question was difficult to answer because none of the current Five Shadows could defeat the Nami Feng Shui Sect, Uzumaki Kushina, and Uzumaki Naruto. The current Five Shadows were all very powerful and each of them had their own unique skills and advantages. Therefore, it was impossible for one person to defeat them.
However, if we consider the combined forces of the Water Gate, Uzumaki Kushina, and Uzumaki Naruto, we might have a better chance of defeating the current Five Shadows. These three ninjas were all very powerful existences. If they joined forces, they might be able to use their respective advantages to cooperate with each other to display even more powerful strength. However, the current Five Shadows were also very outstanding, so even if they joined forces, they might not be able to defeat the Water Gate, Uzumaki Kushina, and Uzumaki Naruto.
There was no definite answer to this question because it was impossible to determine which of the current Five Shadows would win.
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.
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.
