There's also 'Naruto's Childhood Adventures'. This fanfic delves into Naruto's pranks around the village as a child. It's a fun read as it shows his mischievous side, which was also a way for him to get attention in his own way. It has some really heartwarming moments when the villagers start to see him in a different light.
Naruto Boren's time travel to Naruto's childhood was not officially recorded, so it was impossible to determine the exact time. The plot of Bo Ren's time travel to Naruto's childhood had only appeared in some online novels, and these storylines had not been officially recognized.
Obviously Naruto himself is a central character. Sasuke is also very common as he was an important part of Naruto's childhood, being his rival. Sakura is often included too, as she was part of their team. And of course, Iruka - sensei, who was like a father figure to Naruto in his early days.
One aspect of Naruto's sad childhood in fanfiction could be his loneliness. He was shunned by the villagers because of the Nine - Tails inside him. In many fanfictions, authors explore how he coped with this isolation, like finding solace in small acts of kindness from a few people, such as Iruka - sensei.
In some fanfictions, Naruto and Gaara's childhoods are paralleled. Both were outcasts in a way. Naruto was shunned because of the Nine - Tails inside him, and Gaara was feared for the Shukaku. A fanfiction could explore how they might have found solace in each other's similar experiences, had they known about it earlier.
One interesting aspect of Naruto's childhood in fanfiction could be his relationship with Iruka -sensei. In many fanfictions, they have deeper emotional bonds that are explored more in -depth than in the original series. Iruka was like a father figure to Naruto when he had no one else, and fanfictions might expand on how this relationship influenced Naruto's growth during his childhood.
In many fanfictions, their childhood friendship is the foundation. It makes Hinata understand Naruto on a deeper level. For example, she knows his dreams and his pain from when they were young. This understanding helps her support him better as they grow older and their relationship develops.
Friendship is a common theme. In many fanfictions, it shows how Naruto and Sasuke's bond began as kids. It was a unique friendship, full of both competition and mutual understanding.
One interesting aspect could be the exploration of Naruto's relationship with his friends in childhood. For example, how his bond with Sasuke started to form. It might also show his training with Iruka - sensei in more detail, like the challenges he faced and how he overcame them.
Another reason is that it allows fans to fill in the gaps in the original story. We only got glimpses of Naruto's childhood in the anime and manga, so fanfiction gives a chance to go deeper. For example, we can see more of his interactions with the villagers and how he coped with being an outcast. It gives a more in - depth look at his character development during those formative years.
