In a fanfiction scenario, Naruto could bring his ninja skills to the modern Konoha and start a new trend. Maybe he'd teach the modern-day shinobi some of the old - fashioned but effective ninja techniques. Also, he'd be amazed by the new training facilities and the different ways of life. He might struggle with the concept of modern education though, as he was used to the more hands - on ninja training.
He might be really confused at first. The modern world has so many strange things for him like cars and skyscrapers. He'd probably try to use his ninja skills in unexpected ways, like using his shadow clone jutsu to do multiple tasks at once, like shopping and exploring the city simultaneously.
Naruto Doujin novels that traveled back in time to the modern world have not been discovered yet, but there are many Naruto Doujin novels that are based on Naruto's story and characters, telling different stories and worldviews. These novels usually transported Naruto characters to the modern world or continued their stories in the modern world.
In such a fanfiction, Goku might be seen as a very powerful and strange visitor in Konoha. He could start by showing off his amazing strength and speed during a training session with the ninja. Maybe he'd accidentally break some training equipment and leave everyone in awe.
Well, in some fanfictions, Naruto might outsmart Konoha by using his unique knowledge of the village's secrets that others don't know. For example, he could use his understanding of the old tunnels under Konoha to his advantage in a situation where he needs to escape or gain an upper hand in a conflict.
If Naruto travels to the modern world in fanfiction, his character development could be quite interesting. His naivete might initially lead to some comical situations. But as he experiences the modern world, he'd start to question some of his own beliefs. He'd see that the modern world has different ways of achieving peace and justice. His experiences would shape him into a more worldly and perhaps more cautious Naruto. He'd still retain his core values of loyalty and determination, but he'd have a new layer of understanding and wisdom added to his character.
One possible plot could be that Thor arrives in Konoha and is initially mistaken for a powerful new enemy. The shinobi of Konoha are on high alert. But as they soon realize he has no ill intent, Thor starts to learn about the chakra system. He might even share some of his Asgardian knowledge about magic and combat with the ninja. For example, he could teach them new ways of using their physical strength in battle.
Naruto might forgive Konoha because he realizes that holding a grudge won't solve anything. He has seen the destruction that hatred can cause, like during the Pain arc. So, he chooses to forgive in order to move forward and bring about positive change. Another reason could be his respect for the previous Hokages and their ideals for Konoha.
One possible reason could be fear. Naruto has the Nine - Tails within him, and some in Konoha might be too afraid of its power getting out of control. They may not fully trust Naruto to keep it in check.
One popular theme is the daily life in Konoha. It could be about the characters going about their normal days, training, having fun at the local shops, or just hanging out with friends. Another theme is about Konoha during a war or a major threat. How the village prepares, the strategies they come up with, and how the characters, especially Naruto, contribute to the defense. And then there's the theme of Konoha's past. Stories that explore the history of the village, the founders, and how things have changed over time.
