It could also be a redeemed plotline in a very creative sense. Maybe the baby becomes a symbol of change. The fanfiction could explore how love and new life can transform even the darkest of souls, but this would be a very challenging and controversial take.
In most cases, this is likely to be a dark plotline. Given Tom Riddle Jr.'s nature as a power - hungry and evil character, it's hard to imagine a scenario where Hermione having a baby with him doesn't lead to some sort of moral and ethical chaos in the story.
It could be a dark plotline. Tom Riddle Jr. is Voldemort, and having Hermione have a baby with him goes against so much of what is good in the wizarding world. It might involve themes of manipulation and a fall from grace for Hermione.
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.
One great Tom Riddle Jr and Hermione fanfiction is 'A Twist in Time'. In this story, Hermione somehow gets transported back in time and has to deal with a young Tom Riddle. It's really interesting to see how their different personalities clash and interact. The author does a great job of portraying Hermione's intelligence and Tom's growing darkness.
Their relationship could start off with Hermione being extremely cautious around Tom Riddle Jr. But as she tries to understand him more, she might start to see his potential for good. Tom, on the other hand, could be initially intrigued by Hermione's intelligence and different way of using magic. As time passes, they could develop a mutual respect, with Hermione constantly challenging Tom's darker thoughts and Tom starting to question his own path because of her influence.
It's also about the time - travel or alternate universe concepts often used. For example, if Hermione goes back in time, she has the knowledge of the future. How will she use it to deal with Tom? Will she be able to change the course of history? All these possibilities make the fanfiction really engaging. And the power dynamic between them, with Hermione's magic being more learned but Tom's having a natural, dark power, adds another layer of complexity.
There's a fanfic titled 'Hermione's Shadow Encounter with Riddle'. In this story, Hermione is transported back in time and meets a young Tom Riddle. It shows how her modern knowledge clashes with his ancient, dark magic ways. It's a great read if you like stories that explore the contrast between different magical ideologies.
One common theme is the battle between good and evil. Hermione represents good with her values from the wizarding world, while Tom Riddle Jr is the embodiment of evil. Another theme is the power of knowledge. Hermione's vast knowledge often clashes or combines with Tom Riddle Jr's own understanding of magic.
One plot idea could be that Hermione travels back in time and tries to prevent Tom Riddle Jr from becoming Voldemort. She might use her knowledge and magic skills to change his path. Another could be a scenario where they meet in an alternate universe where the rules of good and evil are more blurred, and they form an unlikely alliance to face a greater threat. Maybe Hermione gets trapped in a magically created world by Tom Riddle Jr, and she has to outwit him to escape and in the process, she discovers some hidden secrets about his past that could have changed his future.
One popular 'tom riddle jr and hermione fanfic' is 'A Different Path'. It explores an alternate universe where Hermione somehow gets involved with Tom Riddle Jr in a rather complex relationship. Another is 'Time's Twist' which plays with time - travel elements to bring them together in an unexpected way.
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.
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.
