In Hermione - centered Beauty and the Beast fanfiction, she may also have different relationships with the other characters. The Beast might be more intimidated by her at first because of her magical abilities. And the enchanted objects in the castle could be in awe of her intelligence. For instance, she could use her knowledge of potions to try and find a cure for the Beast's curse, while also forming unique bonds with the talking teapot or candlestick.
The beast is initially portrayed as a terrifying and angry creature. He has a fearsome appearance that scares people away.
Well, Harry in the role of the Beast would be more territorial about Hogwarts, which he now sees as his own 'castle'. He would be hesitant to let Hermione in at first, but slowly open up as he realizes she's different. His scar could be part of his 'beastly' appearance, adding to his sense of being different. Hermione would fit the Beauty role by being the one who brings light into Harry's dark world. She would be patient with him, using her logical mind to try and understand his situation, and at the same time, she would be drawn to his inner strength that she can sense beneath his exterior.
She could be portrayed as a powerful magic - user who aids the Justice League with her unique skills. Maybe she uses her spells to solve problems that the League's normal powers can't handle, like using a spell to break through a magical barrier that's blocking their way.
Often, she is a character full of contradictions. On one hand, she has the potential for great power due to her family lineage. On the other hand, she is determined to be different from Grindelwald. In fanfiction, this can lead to interesting storylines where she has to face challenges from both those who fear her because of her family name and those who want to use her for their own dark purposes.
Another plot twist might be that the Beast is not actually a 'beast' in the traditional sense. In the fanfiction, he could be a wizard under a false appearance curse, and Hermione discovers this. It changes the whole dynamic of their relationship because now they are both magic - users, and she has to figure out how to break the false - appearance curse rather than the typical Beauty and the Beast curse.
In some Hermione fanfiction, the concept of 'erection' might be used in a very discreet and tasteful way to show a character's physical reaction to Hermione's charm or intelligence. For example, it could be part of a scene where a male character is suddenly smitten by her in a more physical sense, but good fanfiction would handle it with subtlety.
Well, in some fanfictions, it might involve a magical or fantastical element that enables the impregnation in a unique way specific to that story's plot.
Often, the Beast courts Belle in fanfiction by sharing his vulnerabilities and slowly opening up to her. This could involve heartfelt conversations or special gifts to win her heart.
In some fanfictions, it might be depicted as a passionate and romantic connection that develops gradually over time.
Maybe Hermione accidentally casts a spell that combines the story of Beauty and the Beast with their world. Harry becomes the 'beast' and Hermione starts to live in the same 'enchanted' area of Hogwarts as him. They gradually develop a deeper understanding of each other. As they explore the magic that binds them in this new situation, they also discover secrets about Hogwarts that were previously unknown.
