What are some interesting plot ideas in Hermione and James time travel fanfiction?

One idea could be that Hermione travels back in time and accidentally gets involved with Lucius in his Hogwarts days. Maybe she has to work with him to prevent a dark magic event that would have far - reaching consequences in the future. This could lead to a strange alliance where they start to see each other in a different light.

One idea could be that Hermione and Bill travel back in time to the founding of Hogwarts. They could witness the four founders making their decisions about the school, and Hermione, with her vast knowledge, might accidentally influence some of their choices. For example, she could suggest a different way of sorting students that gets incorporated into the Sorting Hat's initial magic.

One plot idea could be that Hermione and Rodolphus travel back to the time when the Hogwarts founders were alive. Hermione could use her knowledge to try and influence the early magical laws and education system. Meanwhile, Rodolphus, being from a different era, would have a hard time adjusting and his dark magic - influenced mindset might create conflicts. For example, he might try to introduce some of the more extreme pure - blood ideologies which Hermione would vehemently oppose.

A great plot idea would be that when they time travel, they accidentally change something in the past that has a huge ripple effect on the future. They then have to figure out a way to fix it. Maybe they make it so that Sirius was never disowned by his family in the past, which changes his whole life trajectory. This could lead to a completely different future for the wizarding world, and they have to race against time (again) to make sure the future doesn't go completely haywire.

One plot idea could be that Hermione and baby Teddy travel back to the time of the founders of Hogwarts. There, Hermione uses her knowledge to help the founders with some magical problems they are facing, while Teddy, being a metamorphmagus, unknowingly reveals some future magical abilities to the wizards of that time, causing a stir. Another idea is that they travel to a time during Voldemort's first rise to power. Hermione tries to find a way to stop him earlier, with Teddy's unique abilities helping them to blend in and gather information. For example, Teddy could change his appearance to look like a Death Eater's child to get close to their secrets.

Well, perhaps in the fanfiction, Hermione time - travels to Tom Riddle's era and she attempts to understand his early life better. She could try to find the root of his evil and change it. For example, she might discover that a particular event in his childhood was the turning point. As for Tom Riddle traveling to Hermione's time, he could be fascinated by the advanced magic and the different social structure in the wizarding world, which might make him question his own beliefs.

Another interesting plot could be that they are sent forward in time instead. They have to adapt to the future wizarding world which has changed a great deal. They might be shocked by new magic technologies and different social structures, and their reactions to these changes can make for an engaging story.

A good plot could be them trying to solve the mystery of their parents' past. Since Hermione is a Muggle - born in the original story, this fanfiction could rewrite her backstory to be related to James. They could find out that their parents were involved in some sort of secret magical society that was disbanded years ago, and now they are facing threats from remnants of that society. Another plot might be that they both have a special connection to a magical creature. For example, they discover that they can communicate with a Phoenix that has been guiding their family for generations. They then have to protect the Phoenix from dark wizards who want to use its powers for evil.

She could go back in time to the Triwizard Tournament and use her knowledge of future events to prevent Cedric's death. Maybe she figures out a way to expose Barty Crouch Jr. much earlier. Another plot idea is that Hermione travels back to the time when the Marauders were at Hogwarts. She could interact with them, and perhaps try to influence Sirius Black's fate, making sure he doesn't end up in Azkaban. She might also try to learn more about Remus Lupin's lycanthropy from a different perspective.

One idea could be that Hermione accidentally travels too far back in time with the Time - Turner and ends up in Severus' student days. She has to navigate Hogwarts without being detected while also trying to figure out how to get back. And Severus stumbles upon her and at first is suspicious but then realizes she's from the future and they start to work together to fix the time - line.
