One common theme is loneliness. Naruto already felt lonely in the original story, but losing his family in fanfiction magnifies this. Another theme is revenge. He might be more driven to seek revenge against those who he believes are responsible for his family's death. Also, self - discovery is a big theme. Without his family, he has to figure out who he really is on his own.
Well, in Naruto fanfictions where he loses his family, it often makes his journey even more poignant. It can intensify his drive for power and recognition. He may become more determined to prove himself, not just for himself but also in memory of his lost family. This could lead to different interactions with his friends and mentors, as he might be more guarded or more desperate for a sense of belonging.
It could be an orphan who has been living on the streets of the Hidden Leaf village. This child might have some hidden potential, like being a descendant of a powerful ninja clan but unaware of their heritage.
The theme of survival is often present. Being lost in the Naruto world can be dangerous, so characters have to find ways to survive. They might have to deal with hostile ninja clans or dangerous beasts. Another common theme is the search for a way back. Whether it's back to their own time, place, or to their friends, the character is constantly striving to return to what they consider 'home' in the Naruto universe.
There could be. Fanfiction is a vast realm of creativity. Since both Harry and Carlisle are characters that are likely from different fictional universes (I'm assuming Harry from Harry Potter and Carlisle from Twilight, for example), some fans might have decided to cross - over and create a story where they are long lost family. To find it, you should look for crossovers between the relevant fandoms and then specifically for this family - relation concept.
It could be about Naruto finding and reclaiming a lost child within the Naruto universe. Maybe it's a story where Naruto stumbles upon a child who has lost their way, either literally in the Hidden Leaf village or metaphorically in terms of their ninja path, and Naruto takes it upon himself to help the child find their place again.
One great 'Naruto Lost Tower' fanfiction is 'Time's Echo in the Lost Tower'. It delves deep into Naruto's emotions as he navigates the mysteries of the Lost Tower. The author does an amazing job of exploring Naruto's character growth during this adventure, and the plot twists keep you on the edge of your seat.
A 'lost naruto fanfiction' might involve Naruto being lost in an alternate reality where the Akatsuki are the good guys. He is completely confused at first, but as he spends time there, he starts to understand their motives. He has to decide whether to try and change this reality back to what he knows or accept the new order. It could be a story full of moral dilemmas and exciting battles.
The Hokage, like Kakashi or Tsunade, could also be important characters in this fanfiction. They would have to deal with the political implications of Naruto being a lost prince. Their reactions could range from trying to protect Naruto and use his new status for the good of the village, to being worried about how it will disrupt the existing power structure.
It could be about various things. Maybe it focuses on an alternate story within the Naruto Shippuden: The Lost Tower setting. It might explore different relationships between characters that were not fully developed in the original movie. For example, it could expand on the backstory of some minor characters or create new adventures for Naruto and his friends in that particular time and place.
