In a Konoha 12 see the future fanfiction, many things could occur. They might see the destruction of Konoha and strive to prevent it. For example, Naruto could use his future knowledge to better train and unite the village. Sakura might focus on advancing her medical skills even further to deal with future threats. And Sasuke could use the knowledge to avoid certain paths that led to his past miseries.
In this fanfiction, the Konoha 12 might see various things in the future. They could witness new threats emerging to the village. For example, a powerful enemy that they have never faced before. Maybe they'll see changes in their relationships as well. Some of them might become closer, while others could grow apart due to future events.
Well, they might see a future where they have a big family. Since Naruto always wanted to be acknowledged and have people around him, he could see himself surrounded by his children and Hinata in a happy home. And for Hinata, she might see herself as a strong kunoichi, still supporting Naruto in his Hokage duties.
In the fanfiction, they might gain valuable insights. For example, Naruto could learn from his future self how he has truly changed the village. Sakura might see her future medical achievements and be inspired to work even harder in the present. And Sasuke could get a glimpse of whether he has truly found peace or not, which could potentially change his current actions and decisions.
If they saw the future, perhaps Naruto would see himself failing to save Sasuke. This could make him change his approach towards Sasuke, trying to understand his friend's pain more deeply and find a better way to bring him back to the right path. They might also foresee new and powerful enemies emerging, and start to search for allies or new jutsu to counter them.
If the Konoha 12 saw the future, their relationships would be greatly affected. Naruto and Sasuke's bond might strengthen as they work together to avert future disasters. Sakura might become more understanding of Sasuke's actions in the future she saw. Shikamaru and Choji could start training together more intensively, preparing for what's to come.
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, if Konoha 12 watches the future 7th Naruto in fanfiction, they would probably have mixed reactions. Some, like Shikamaru, might immediately start thinking about the implications of Naruto's future actions on the present. Others, like Kiba, might be more excited to see Naruto's new jutsu or how he has become even stronger. And Sakura might be emotional, seeing how Naruto achieved his dream and how much he has changed from the boy she once knew.
It could lead to some really interesting plot twists. Maybe Goku could prevent major disasters before they happen and change the course of events in the Dragon Ball universe.
In this fanfiction, the Naruto family might be welcomed back with great joy. The villagers could hold a big celebration to honor their return. Naruto, as a hero, would finally be home with his family in Konoha, and his kids might start exploring the village that their father has so many memories of.
One possibility is that Naruto is being captured for a misunderstanding. Maybe Konoha has received false information about Naruto being a threat. In the fanfiction, this could lead to his friends having to prove his innocence.
