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 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 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.
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.
Well, one aspect to consider in a Tom Riddle and OC fanfic is the portrayal of Tom Riddle himself. If it's well - written, it can show his complex character, his path to becoming Voldemort. The OC in such a fic can add a new dimension. Maybe the OC is someone who tries to prevent his fall into the dark side. However, some fanfics might not do justice to the original lore and make Tom too soft or the OC too overpowered.
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.
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.
One great Tom Riddle and OC kiss fanfic is 'A Darker Shade of Love'. It really delves into the complex relationship between Tom and the original character. The kiss scenes are written with a lot of emotion and tension, making it a great read for those who like this pairing.
Power struggle is also quite prevalent. The OC often has some sort of power or knowledge that either challenges or complements Tom Riddle's own power. For example, the OC could be a seer, and their visions of the future clash with Riddle's plans. This creates a tense dynamic throughout the story.
The storyline of a Tom Riddle and OC Rhurst fanfic might revolve around the power dynamics between them. Since Tom is a powerful and manipulative character, he might try to overpower Rhurst. But Rhurst, being an original character, could have her own strengths and weaknesses. For instance, she might be very empathetic, which could both be a strength in understanding Tom's troubled past and a weakness as he could use her empathy against her.
