The story could take many directions. Fem Harry might try to find out what went wrong in Tom's early life that led him to become Voldemort. Maybe she discovers some family secrets or hidden traumas. And as Tom grows up under her care, he could start to develop a different personality. He might become more empathetic and less power - hungry because of the loving environment Fem Harry creates for him.
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.
One common theme is redemption. Since Tom Riddle later becomes Voldemort, the idea of fem Harry being able to change his path and redeem him is often explored. It gives a sense of hope that even the darkest of characters can be saved.
At first, it might be rocky. Tom would be suspicious of Harry's intentions. But as Harry shows him genuine care, Tom would start to open up. Eventually, they could become like family, with Tom looking up to Harry as a role model.
I think the story could take many turns. Harry, as Tom Riddle, might try to change the course of events he knows led to evil. Or he could be tempted by the power that Tom once craved. It would be a complex web of internal and external challenges.
One popular 'fem Harry adopts Tom Riddle fanfiction' is 'A Different Kind of Family'. In this story, the female Harry takes Tom under her wing in a really interesting way. It explores how their relationship develops over time, with some unique twists on the magic world we know from the original series.
Hermione would probably be very cautious at first. She would be worried about the potential danger that Tom Riddle could pose, even as a child. But she might also see it as an opportunity to study the roots of dark magic and how to prevent someone from turning to the dark side.
At first, it would probably be really tense. Tom is used to being on his own and having his own dark thoughts. Harry would be super cautious. But as time goes on, Harry's kindness might start to break through Tom's barriers. They could become like brothers, with Harry teaching Tom about the good in the world and Tom starting to trust Harry.
One unique way is through a shared secret. For example, Fem Harry discovers a hidden part of Hogwarts that is related to a powerful and ancient magic. Tom Riddle also stumbles upon this secret. Instead of fighting over it, they decide to explore it together. During this process, they rely on each other's skills and knowledge. This shared adventure builds a deep bond between them, and they start to see each other in a new light, far from their initial impressions.
Harry would likely use his own experiences of facing inner darkness. He could talk to Tom about his struggles with the part of Voldemort that was in him. By sharing his own story, he hopes to make Tom understand that he has a choice and doesn't have to give in to any dark desires.
As the story progresses, their relationship could become more complex. Harry might become a father figure to Tom, teaching him right from wrong. Tom, on the other hand, could start to see Harry as someone he can rely on, but also struggle with his own inner demons that might pull him away from Harry's influence.
