A good Hermione Granger x Male OC fanfiction should first of all keep Hermione's character intact. She's known for her intelligence, loyalty, and strong - willed nature. So if the story has her suddenly acting out of character just to fit the relationship with the OC, it's not good. For example, she wouldn't easily abandon her studies for a guy. Secondly, the male OC should be well - developed. He should have his own backstory, motives, and personality. If he's just a blank slate or a Mary - Sue type character, it won't be interesting. Finally, the relationship between them should develop naturally. It can't be love at first sight without any real connection or build - up.
One common theme is the clash of cultures. The magical world Hermione comes from and the muggle world of the male character are very different. They have to deal with things like magic being a mystery to the muggle and the muggle's normal life being strange to Hermione.
One common theme is friendship turned into love. In many of these fanfics, Harry and Hermione start as friends, as they are in the original series, and then their relationship evolves into something more romantic over time.
Hagrid can be characterized as his usual kind - hearted self, but with a newfound fascination for the lemons. He might be a bit clumsy with handling the lemon - related magic at first. Hermione, on the other hand, is her studious and inquisitive self. She is eager to learn all she can about the lemons and how they fit into the wizarding world. For example, she would be constantly taking notes and making theories.
Well, Harry Potter is likely to be one of the main characters. He's always been an important part of Hermione's life in the original series, and in this fanfic, he might play a crucial role in the events related to the Half - Blood Prince. Maybe he and Hermione are on a joint mission to uncover the secrets of the Half - Blood Prince.
The contrast between the two characters. Hermione is a brilliant, studious witch, while Fenrir is a savage werewolf. This contrast can lead to some really interesting character dynamics in fanfictions.
Romantic plotlines are also popular. For example, Hermione could end up in a relationship with Shepard. Their different backgrounds - one from a world of magic and the other from a high - tech space - faring civilization - can create a lot of interesting dynamics in the relationship. They might teach each other about their respective worlds and grow together.
