In this fanfiction, Harry Potter visiting the future would be a wild adventure. He might discover that some of the old magical artifacts he knew have new uses or powers. He could also encounter threats that are different from what he faced in his own time. For example, there could be a new dark wizard or a group of dark wizards who have found a way to use modern technology combined with magic in a dangerous way. And his own legacy in the future could be a big part of the story. People might see him as a great hero or there could be some who misinterpret his actions from the past. Harry would have to navigate this new world while still holding onto his own values and experiences from his time at Hogwarts and during his battles against Voldemort.
Well, he might be shocked by how things turn out. He could see the fates of his friends, like whether Ron and Hermione's relationship endures. Maybe he'd find out if Hogwarts still stands strong or if there are new threats to the wizarding world that he hadn't anticipated.
He might meet the future versions of his friends like Hermione and Ron. Their children or grandchildren could be there, and they might have different personalities and magical skills compared to their predecessors.
In this fanfiction, Harry might see a world where magic has evolved in unexpected ways. For example, there could be new spells that are far more powerful and complex than the ones he knew. He could also find that Hogwarts has changed, perhaps with new buildings or different teaching methods. And maybe he would encounter descendants of his friends, who have their own unique stories to tell.
Perhaps he would find that the wizarding world has finally united with the Muggle world in harmony. Technology in the Muggle world could have influenced magic in strange and wonderful ways. He could be shocked to see flying cars that are now common, or houses that are built with a combination of magic and advanced Muggle construction techniques.
He might also be a bit confused at times. Some fanfictions deviate a lot from the real events in his life. For example, if there's a fanfiction where he has a completely different upbringing, it would be strange for him to read about. He could also feel a sense of flattery that so many people are interested in his story and want to create their own versions of it.
He might be really surprised. Fanfiction often contains different interpretations of the characters and the story. He could be amused by some creative ideas, or perhaps a bit confused if the fanfiction goes too far from the original story he knows.
The idea of Harry Potter with a gun is quite interesting. One possibility is that he gets the gun from the muggle world accidentally. He might initially be confused about how to use it but then realizes its potential. This could lead to new alliances in the wizarding world. Some wizards might be intrigued by this new weapon and want to learn more about muggle technology, while others might be afraid and try to confiscate the gun from Harry.
It would be really strange. He might be very confused as fanfiction often contains different interpretations and sometimes wild ideas that are far from his own experiences. He might think it was some kind of strange magic that created these alternate stories about him and his friends.
Well, he could bring his magic skills to the team. Maybe he'd use spells like 'Expelliarmus' to disarm villains before the Avengers could even react. His ability to apparate could also be useful for quick getaways or surprise attacks on enemies.
He might be shocked. In fanfiction, the future could be full of strange twists. For example, if his friends' children are involved in some wild adventures that are very different from what he expects. He would probably be confused at first, then curious to understand how things got to that point.
