Perhaps Tom Riddle discovers a time - traveling spell and travels to the future to meet Harry Potter. He sees the power Harry has and tries to manipulate him into joining his dark side in the past. But Harry, being aware of Tom's true nature, resists and tries to find a way to stop Tom from ever becoming Voldemort. This could involve a lot of battles of wits and magic between them.
One idea could be that Harry accidentally travels back in time and meets a young Tom Riddle before he fully turns evil. He tries to change Tom's path by befriending him and showing him kindness, which leads to a series of events where the future of the wizarding world starts to change in unexpected ways.
In a time - travel scenario, Harry could go back to Tom's school days at Hogwarts. He might try to prevent Tom from opening the Chamber of Secrets. Harry could team up with the young Dumbledore at that time, and together they try to influence Tom's choices. This would not only change Tom's fate but also the history of the Chamber of Secrets incidents and the future threats to the wizarding world.
A possible plot is that a young wizard, who is a huge fan of Harry Potter stories in his own time, somehow gets transported back to Tom Riddle's era. He initially just wants to see the famous Hogwarts of that time. But then he crosses paths with Tom Riddle. He decides to use his knowledge of the future to try and befriend Riddle and change his path. However, he soon realizes that Riddle is far more complex and dangerous than he expected, and his actions start to have unforeseen consequences on the future.
One idea could be a time - travel fanfic where Harry goes back in time and tries to prevent Tom Riddle from becoming Voldemort. He could try to befriend the young Tom and show him a different path. Another could be a fanfic where Harry and Tom are somehow trapped in an alternate dimension together and have to work together to escape, all while Harry tries to understand what made Tom turn so evil. A third idea is a fanfic where Tom Riddle actually has a change of heart early on due to some magical accident that makes him experience a different kind of love and kindness, and Harry has to deal with this new Tom in Hogwarts.
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.
Perhaps Ginny and Tom both travel to a different time period, like the Middle Ages. There, they have to work together to survive in a world full of magic they don't fully understand yet. Ginny could use her modern knowledge of magic, while Tom's natural cunning helps them navigate the social and political aspects of that time. This could lead to a strange alliance and a re - evaluation of their relationship.
In a 'Harry Potter meets Tom Riddle' fanfiction, a really unique plot could be that Tom Riddle is reborn as a normal wizard without the dark desires due to some powerful magic. Harry Potter meets this new Tom and they become friends at Hogwarts. However, there are still some remnants of the old Tom's power that attract dark forces. So, Harry and Tom have to work together to fend off these threats while also exploring Tom's new identity and how it affects the future of the wizarding world.

One idea could be a time - travel plot where Harry goes back in time and tries to prevent Tom Riddle from becoming Voldemort. He could try to befriend the young Tom and show him a different path. Another could be a scenario where they are both put in a magically created alternate reality where they have to work together to escape.
The exploration of their relationship is also a major theme. In many fanfictions, Harry tries to understand Tom Riddle, and they develop a complex bond that may range from enmity to a strange kind of understanding. For example, in some stories, they might start to see each other's points of view, which changes their relationship dynamics. This is especially interesting considering their roles in the original series. They are enemies, but time - travel gives an opportunity to rewrite that narrative in a way.
A possible plot is that Harry travels back and accidentally disrupts the timeline. As a result, things start to change in the present he came from. He has to figure out how to fix it while dealing with Tom. Maybe he tries to mentor Tom in a positive way, showing him the value of Muggle - born wizards. This could create a ripple effect where Tom doesn't grow to hate Muggles and non - purebloods. Also, Harry could discover new spells or magic that was lost over time while in Tom's era and bring that knowledge back to his own time if he manages to return.
One interesting plot could be a time - traveling character going back to Tom Riddle's school days at Hogwarts. They might try to prevent him from becoming Voldemort.

This could change the entire future of the wizarding world.
There's also 'Time's Twist'. In this fanfiction, time - travel is used as a means to change the future by interfering with Tom Riddle's past. Harry's character development throughout the story as he tries to deal with Riddle is really engaging.
