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.
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.
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.
Another one is 'Time Travel Trials'. The plot here is that the Golden Trio travels back in time due to a dark magic experiment gone wrong. They land in a time when there is a civil war among the wizarding community. They must use their skills and knowledge to stop the war and also find a way to reverse the time - traveling spell. It's unique because it's not just about changing the past at Hogwarts but about a much larger scale event in the wizarding world.
One interesting plot could be that they go back in time to prevent a major tragedy from happening at Hogwarts. For example, they might stop the basilisk from being released in the Chamber of Secrets before it causes any harm. Another plot could be that they travel back to the time of the founders of Hogwarts and get involved in the early disputes and decision - making of the school. Maybe they accidentally change something that has a huge impact on the present Hogwarts they know.
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.
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.
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.
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.
Well, a cool plotline is when the Golden Trio travels back to the Triwizard Tournament. They could use their future knowledge to help Cedric survive. Maybe they can stop Barty Crouch Jr. from impersonating Mad - Eye Moody and causing all that chaos. They might also be able to change how the tasks are completed, making it more of a fair competition. And think about the interactions they'd have with the other champions! They could form alliances and share magical knowledge that wasn't available at that time.
