One possibility is Neville. He has always been a kind - hearted and brave character. In the fanfiction, he could be a knight or a nobleman who has a secret admiration for Hermione. As she becomes a princess, he might finally gather the courage to approach her. Or perhaps a wizard from a far - off land, who has heard of Hermione's intelligence and beauty and travels to court her. This wizard could bring new magic and different perspectives into Hermione's life, and a potential love story could unfold between them.
Perhaps a mortal with a special gift for metallurgy or some other craft related to Hephaestus' work. This mortal could be seen as an equal in terms of skill, at least in a way that catches Hephaestus' eye. They would bond over their shared love for the craft, and over time, this bond could turn into a deep, loving relationship. Hephaestus might be drawn to the mortal's unique perspective and the way they approach the craft despite not having the same divine powers as he does.
Hinata is a very obvious choice. She has always had deep feelings for Naruto. In a fanfiction, their relationship could spiral further, exploring more of their shared interests, like their love for the village and their dreams for the future of the ninja world.
One potential partner could be Neville Longbottom. He has grown a lot throughout the series, and in a fanfiction, they could secretly marry. Maybe they discover a deep connection during their post - Hogwarts adventures. Another could be Draco Malfoy. It's a popular choice in fanfictions as they start to see different sides of each other after the war and end up secretly getting married.
If it's a crossover with the Percy Jackson universe, Percy himself could be interested in Ruby. They both have a sense of adventure and a desire to protect their friends. Annabeth might find herself drawn to Weiss because of their shared intelligence and strategic thinking. Leo Valdez could have a crush on Yang due to her mechanical skills and fiery personality. And Nico di Angelo might be intrigued by Blake because of her mysterious nature. These could all be great potential love interests in a RWBY - Percy Jackson crossover harem fanfiction.
Ezra might also be a possibility. He could be involved in a complex relationship with Spencer where he has to deal with her pregnancy and all the emotions that come with it.
There could be an older, more mature character, like a college student who she meets by chance and who is drawn to her unique charm and innocence.
It could be a figure skater. Maybe a rising star in the skating world who Bella meets at a competition and they strike up a connection. He might be drawn to her passion for the sport.
She might meet a young and talented French wizard who is a master at transfiguration. He could teach Hermione some advanced techniques and they could become good friends or even rivals in the field of magic.
The potential kidnappers could be a secret society within the wizarding world that has its own agenda. They might believe that Hermione has a special power or connection that could either help or harm their cause, so they took her at birth to control that. It could also be a non - human magical being, like a centaur or a goblin, who thought that Hermione's birth was a sign of something significant in the magical world. They kidnapped her to study her or use her in their own cultural or magical practices. Or perhaps it was a wizard who had a grudge against Hermione's parents and took their child as revenge.
Sakura could be a potential love interest. Since Naruto has always had a connection with her, as a girl, that connection could turn into a yuri - like romantic relationship. They already know each other well, and Naruto's new form could make Sakura see her in a different light.
