Some interesting plot ideas could involve the OC being a Muggle - born with an extraordinary gift. Tom Riddle Jr. initially despises the OC for being Muggle - born but then realizes their gift could be useful for his own ends. For instance, the OC might have an uncanny ability to understand ancient runes that hold the key to some dark magic Tom Riddle Jr. wants to access. Another could be that the OC is an Animagus and uses their animal form to spy on Tom Riddle Jr., leading to a cat - and - mouse game between them as he tries to figure out who is spying on him and the OC tries to expose his evil plans.
One idea could be exploring Tom Riddle Jr.'s relationship with the original characters in a new way. For example, how he might interact with Dumbledore when there's an OC involved. Maybe the OC has a special power that Dumbledore is interested in, and Tom Riddle Jr. sees this as a threat or an opportunity. Another plot idea could be the OC coming from a different magical culture and introducing Tom Riddle Jr. to new forms of magic, which could either corrupt him further or, surprisingly, make him question his dark path. Also, a plot where the OC is a time - traveler and tries to prevent Tom Riddle Jr. from becoming Voldemort could be really exciting, full of twists and turns as they battle against fate.
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.
First, think about the OC's motivation. What drives them in the world of Hogwarts? Is it a thirst for knowledge, a desire to fit in, or something else? This will shape their actions and decisions. Then, develop their relationships. How do they interact with other students, teachers, and especially Tom Riddle Jr.? Their magical abilities should be consistent and logical. If they're good at Defense Against the Dark Arts, explain how they developed those skills. For example, did they have a mentor? And don't forget about their flaws. A believable OC has weaknesses, like being too trusting or having a quick temper.
One common theme is the struggle between good and evil. Since Tom Riddle Jr. is on his path to becoming Voldemort, the OC often has to decide whether to support his darkening ways or try to turn him towards the light. Another theme is the exploration of Tom's past. The OC may dig into his family history or his time at Hogwarts before he fully embraced the dark arts.
In this type of fanfic, a really interesting plot might be that Harry and Tom Riddle are in an alternate reality. In this reality, Hogwarts has a different set of rules and magic. They are both outsiders in this new world. They start to rely on each other for survival, and in the process, they discover new aspects of their magic and themselves. Harry tries to use this opportunity to redeem Tom Riddle, while Tom is constantly tempted by his old, dark ways.
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 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.
Well, perhaps in the fanfiction, Hermione as a Veela has the ability to enter Tom Riddle's dreams. In his dreams, she shows him the consequences of his future actions as Voldemort. This makes Tom start to have doubts about his planned path of evil, and he has an internal struggle between his dark desires and the newfound influence of Hermione's Veela presence.
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.
One plot idea could be that Fem Harry, with her unique perspective as a female in a male - dominated wizarding world, catches Tom Riddle's attention in Hogwarts. He's intrigued by her different way of approaching magic. Maybe she's more empathetic and uses magic in a way that he's never seen before, leading to a complex relationship where he both admires and is jealous of her power.
I really like the 'tom riddle jr and oc fanfiction' titled 'Shadows of the Past'. In it, the OC has a past connection to Tom Riddle Jr. that gets revealed slowly throughout the story. It has a great plot with lots of mystery. There's also 'A Different Tom' which shows a more vulnerable side of Tom through his interactions with the OC. It's a unique perspective on his character.
