How would the characters of Harry, Ron and Hermione be different if they go back in time in fanfiction?

Well, they could change their own relationships. Perhaps Hermione would be able to help her younger self be more confident. Ron might stop himself from making some of the silly mistakes he made in the past. And Harry could get to know his parents better. They could also influence the development of magic in Hogwarts. For instance, introduce some new spells or magical concepts they learned in their original time.

The main characters are Harry and Hermione, of course. Harry, the Boy Who Lived, with his Gryffindor courage and his special connection to Voldemort. And Hermione, the brilliant and studious witch, always full of knowledge and quick thinking.

Their relationships might become more complex. In Slytherin, there's often a sense of competition and self - preservation. Ron and Harry's friendship could be tested as they might be vying for the same opportunities or recognition within the house. Hermione might be more on her own as she tries to uphold her own values while also fitting into the Slytherin mold. The three of them might not have the same tight - knit bond as in Gryffindor since Slytherin values can sometimes promote individualism over group loyalty.

Maybe they miss their old school days. Hogwarts was such an important part of their lives.

If Naruto and the Bijuu go back in time, Naruto's relationship with Madara could be completely transformed. Instead of being enemies in the future timeline, Naruto could try to understand Madara's motives from the start and perhaps prevent him from going down the dark path. The Bijuu, on the other hand, might have a different relationship with the Uchiha clan in general. They could offer their power to the Uchiha in a more positive way, rather than being something the Uchiha might try to control in the future.

Hermione would probably be deeply hurt at first. She trusts Harry and Ron so much, and being abandoned by them would be a huge blow. But she's also very determined. So, she might throw herself into her studies even more, using her knowledge as a way to cope and also to find a solution to the situation.

Well, they might change some important events. For example, they could prevent certain tragedies from happening in the wizarding world. Maybe they'd save some characters who died in the original timeline.

If they joined Voldemort, Harry might lose some of his natural courage. He'd be in a world where his usual values are flipped, and this could make him seem more hesitant. Hermione would probably have to hide her intelligence more. Voldemort doesn't like those who are too smart or independent. So she might act more subservient in public, but in private, she'd be devising plans to break free and expose Voldemort's true nature.

At first, Harry might be confused. He would try to figure out what went wrong. He might search his memory for any signs that could have led to this betrayal. Then, he would likely experience a range of emotions from sadness to rage. Depending on the nature of the betrayal, he could either try to win them back by showing them the truth or decide that they are no longer worthy of his friendship and focus on his own path, maybe even leaving the wizarding world for a while to clear his head.

Their presence could change history in many ways. If they introduced modern spells or magical concepts, it could accelerate the development of magic. For example, Hermione's knowledge of advanced spells could be passed on. Ginny's boldness might inspire students of that time to be more courageous. Luna's open - mindedness could change the way people think about magic and the unknown. They might also accidentally change the course of important events, like the outcome of a wizarding duel or the selection of a Hogwarts headmaster.
