past sanegiyuu meets their future selves

One interesting scenario could be that their future selves are not what they expected at all. Maybe Naruto's future self is not as happy as he thought he would be. Sasuke's future self could be facing new challenges that he didn't anticipate. Sakura might find that her future self has made some sacrifices she hadn't considered. This would make them re - evaluate their current paths.

The answer to the question that humans would travel to the past and meet their past selves in the future was not absolute because there was no scientific evidence to prove this. However, according to some novels and science fiction works, humans might encounter their past selves in the future, but this depended on many factors such as whether the technology of time travel was available, whether the time they traveled to the past was close enough to their past selves, and so on. In some novels, humans travel back in time to meet their past selves. These plots often involve some mysterious scientific principles such as "time tunnel" or "time warp", which may allow humans to travel through time and meet their past selves. But in reality, we currently have no scientific evidence to prove this possibility. In short, it was still unknown whether the future could travel to the past and meet the past. More scientific research and evidence were needed to confirm it.

The relationship between Naruto and Sasuke could become more complex. If Sasuke's future self has accomplished great things but at a cost, Naruto might question his own ideas of success. For Sakura, seeing her future self might make her more assertive in her relationship with the boys, especially if she has become a very respected ninja.

Captain America would probably be very reflective. He might see his past self as a reminder of his long journey and how much he has changed. He could try to offer some words of wisdom to his younger self.

Another theme is the exchange of knowledge. For instance, a character from the past might have some unique skills or knowledge that is valuable in the future, and vice versa. They then share and learn from each other, like an ancient herbalist teaching future doctors about natural remedies that have been forgotten.

The main characters in the 'httyd meet their future selves fanfic' would be those who are crucial to the story of Berk. Hiccup, as the protagonist, is a given. Toothless, his dragon companion, is also essential. Astrid, being Hiccup's love interest and a strong warrior in her own right, would be there. And then there are the other members of the Dragon Riders like Fishlegs, who is known for his knowledge, Snotlout, who is full of bravado, and the Twins, who bring their unique brand of humor and chaos. All of them together form the core of the How to Train Your Dragon universe and would be the main characters in this fanfic.

In this fanfic, they might discover amazing things about their future. For example, they could see how their relationships have evolved, like Hiccup's leadership in Berk might have reached new heights in the future. Maybe Toothless would have some new abilities or a different role in the future Berk.

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.

Past Percy is likely to be more impulsive. He hasn't faced as many challenges yet and might act before thinking. Future Percy, on the other hand, would be more cautious and calculating, having learned from past experiences.

One way is through time - travel jutsu. A character could accidentally or intentionally use a jutsu that sends them to the future or past. For example, Naruto might find a hidden scroll with a time - travel jutsu and end up in the future where he sees how his friends and the village have changed. This could lead to interesting storylines where he tries to fix things or learn from the future.
