If Hermione adopts Tom Riddle, it could potentially prevent the rise of Voldemort. This would mean a much more peaceful wizarding world. There would be no First or Second Wizarding Wars, and countless lives would be saved. Families like the Potters and the Weasleys would not have to endure the pain and loss they suffered in the original timeline.
It could also change the way magic is taught. Hermione, with her experience in teaching Tom, might introduce new methods of magical education. For example, she could emphasize the importance of ethics and morality in magic from an early age. This could lead to a new generation of wizards and witches who are more responsible and less likely to use magic for dark purposes.
It would change the future of the wizarding world a great deal. Hermione is a smart and kind - hearted witch. With her as Tom's mother figure, she would likely encourage his academic pursuits in a positive way. He might grow up to be a great wizard who uses his powers for good instead of evil, thus changing the whole power dynamic in the wizarding world.
The story could also involve Hermione using her magical knowledge to help Tom control his powers. Since Tom is a powerful wizard from a young age, he might have difficulty handling his magic properly. Hermione, being a brilliant witch, could guide him. This could lead to a unique bond between them, where Tom respects Hermione for her abilities and Hermione sees the potential for good in Tom.
The wizarding world would be in shock at first. But over time, if Fem Harry is successful in raising Tom right, it could lead to a more peaceful future. There might be less fear and prejudice as Tom doesn't become Voldemort.
Well, in fanfiction, anything can be possible. It could be possible through some dark magic or a complex time - travel plot. Maybe a spell went wrong and created a connection between Hermione and Tom Riddle that led to her being his daughter. However, in the original "Harry Potter" lore, it's completely against the nature of good and evil as Hermione is on the side of good and Tom Riddle is the evil Lord Voldemort.
Hermione would likely approach Tom's dark past with a great deal of research. She'd probably dig into the history of Voldemort's early years to understand what led him down that path in the first place. By knowing the root causes, she could try to prevent the same things from happening to Tom. For example, if she found out that loneliness and a sense of being an outcast were factors, she'd make sure Tom had a strong support system at Hogwarts.
One possible plot twist could be that Tom Riddle's dark tendencies start to resurface despite Hermione's positive influence. Maybe he begins to secretly manipulate those around him at Hogwarts while still maintaining a facade of being a reformed child. This could lead to a rift between Hermione and some of her friends who suspect Tom but don't understand why Hermione is so trusting.
She would face the challenge of dealing with Tom's own nature. Even as a baby, he might have some of the traits that later led to his dark side. Hermione would have to find ways to nurture his good side and suppress the bad. Also, she has her own life and studies. Balancing taking care of a baby and her own development would be difficult.
It can make her more involved with the pureblood families. She might have to attend more pureblood - related events, which could be both good and bad. Good because she gets to understand them better, but bad as some might still be prejudiced against her.
One interesting aspect of Hermione Granger and Tom Riddle fanfiction is the exploration of what could have been if they had met in different circumstances. Some fanfictions might depict Hermione as a force for good trying to redeem Tom Riddle before he becomes Voldemort. For example, she could use her vast knowledge of magic and her strong moral compass to guide him away from the dark path. This creates a really fascinating dynamic as it pits Hermione's light - filled values against Tom's budding darkness.
The wizarding community would be horrified. Hermione is seen as a hero, and Tom Riddle Jr. is the most feared dark wizard. It would be a scandal that would rock the community to its core.
