Well, it would be a really chaotic situation. Harry would be able to see his parents again in the Order of the Phoenix time. Hermione would probably be super focused on not disrupting the timeline too much, but Ron might accidentally cause some small changes just by being his clumsy self. And they'd have to deal with the younger versions of themselves as well, which could lead to some really interesting and confusing interactions.
They might try to change certain events. For example, they could attempt to save Sirius earlier. Maybe they'd use their knowledge of future events to outwit Voldemort's plans more effectively in that time period.
The time travel could put some strain on their relationships at first. Harry might be more focused on seeing his godfather again, Ron could be a bit jealous if Harry's attention shifts too much, and Hermione would be constantly worried about the rules of time travel. But as they work through these issues, they'd likely come out with a deeper understanding and respect for each other. They'd also have to hide their true identities from the people in that time, which would require a lot of trust among them.
Well, in the future they could encounter different versions of themselves or their descendants. Maybe they would find that Hogwarts has changed a great deal, with new spells being taught that were unimagined in their time. And they might have to face new dark forces that have emerged over the years, using both their old - school magic knowledge and learning new ways to combat the threats.
Harry's personality is deeply influenced by his experiences with Voldemort. In the past, he might be more carefree initially but would quickly become a protector when faced with threats. His presence could inspire those in the past to be braver. Hermione, being the book - smart one, would try to correct historical inaccuracies in magic theory. This could lead to a revolution in the way magic was taught in the past. Ron, with his down - to - earth nature, would probably make friends easily. He could introduce muggle - like concepts to the wizarding world of the past, which might change their view of non - magical people.
One interesting concept could be how the Golden Trio - Harry, Hermione, and Ron - deal with changing the past and the potential consequences. For example, they might try to prevent certain tragedies from the original story, but in doing so, create new and unforeseen problems.
One interesting Golden Trio time travel fanfiction is 'Back to the Beginning'. In this story, Harry, Hermione, and Ron travel back in time to their first year at Hogwarts. It's really cool as they use their future knowledge to change some small things and also prevent some potential disasters. They have to be careful not to disrupt the timeline too much, which adds a lot of suspense to the story.
Hermione would start by studying all the new things she could find. Ron would follow Harry's lead most of the time. Harry would use his instincts to figure out who to trust in this new future.
There's a fanfiction called 'First Year Redo'. In this story, the Golden Trio goes back to their first year and decides to focus on befriending some characters they didn't get to know well before. They also use their knowledge to prevent some small, but annoying things that happened in their first year from occurring again. It's a heartwarming story that shows how much they've grown since their first year at Hogwarts.
A lesser - known but great one is 'Time - Twisted Bonds'. In this story, the time travel element is used to create unexpected alliances and conflicts between the Golden Trio and the Black Sisters. It starts off with a bang as the characters are thrust into the different time periods, and the plot unfolds in a very thrilling way.
Harry would likely be the brave and impulsive one. He might be the first to jump into action when they face challenges during their time - traveling adventures. His role could also be to use his natural leadership skills to guide the group.
One common theme is redemption. For example, some Black Sisters characters might get a chance to redeem themselves through their interactions with the Golden Trio during time travel. Another theme is the exploration of family secrets. Since the Black Sisters have a complex family history, time travel can uncover long - hidden secrets.
