It makes her seem more powerful. Traditionally, Hermione is seen as the brains of the trio, but in this fanfiction, she's scarier, which implies a new level of power that goes beyond just being intelligent. It gives her an edge that we don't usually associate with her character.
Maybe it's her intelligence. Hermione is extremely smart and could use her knowledge in unexpected and intimidating ways that Voldemort, with his more brute - force and dark - magic - based approach, might not anticipate. For example, she could outwit him strategically in a battle of wits rather than relying on raw power like Voldemort does.
In a fanfic with Hermione as Voldemort's spy, it's a very interesting concept. First of all, Hermione is known for her intelligence and loyalty in the original series. But if she's a spy, her intelligence could be used against the good guys. She could be using her knowledge of spells and magic to deceive her friends. The plot could involve her gradually realizing the error of her ways and trying to turn against Voldemort. Or perhaps she's so deep in the spy role that she becomes a real antagonist, causing chaos and destruction among the characters we love.
She is likely to be defiant. Hermione has always been a strong - willed character. So she would probably not go down without a fight. She might immediately start looking for ways to escape or undermine Dolohov's plans.
Well, if Hermione was adopted by Voldemort in fanfiction, it would completely change the dynamic. First, Hermione's intelligence could be used in very different ways. She might be forced to use her knowledge to help Voldemort's dark plans, but she could also secretly try to undermine him from within. Second, her relationships with other characters would be altered. For example, her friendship with Harry and Ron would be put to the test. They would likely see her as a traitor at first, but later might realize she's playing a double - game. And finally, Voldemort himself might change. Having Hermione around could expose him to different ideas, though he'd probably resist them. It's a really interesting concept for a fanfiction.
Hermione's development in this type of fanfiction is a journey of self - discovery. Initially, she is in a state of shock and despair at being enslaved by Voldemort. But as the story progresses, she discovers inner strengths she didn't know she had. She becomes more self - reliant as she can't always count on her friends to rescue her. Her moral compass may shift slightly as she has to do things she wouldn't normally do to survive. For example, she might have to lie or deceive more often. However, through it all, her core values of intelligence and loyalty still shine through, but they are tempered by her new experiences in this dark world.
It changes the story by adding a new layer of heroism to Snape. In the original, his heroism was more in the background. But here, he becomes Hermione's savior from Voldemort. This could also change Hermione's view of Snape completely.
Well, it could change a lot. For example, Hermione might have some internal conflict about her family connection to Voldemort. Maybe she would try to hide this fact from her friends. Also, Voldemort might have different plans regarding Hermione, instead of just seeing her as an enemy like in the original story.
Hermione would likely become more conflicted. Her usual confidence and surety in her beliefs would be shaken. She might become more withdrawn as she struggles with the implications of her new identity. She may also start to show more signs of ruthlessness, a trait associated with Voldemort. For example, she could be less hesitant to use extreme measures to achieve her goals.
She loses her moral compass. Normally, Hermione is a very ethical character, but in these fanfictions, she may start to see the dark arts as a viable option without hesitation. This could lead to her making choices that harm others, like casting harmful spells on those who oppose her.
She becomes more in tune with nature. As a centaur, Hermione is closer to the natural world, and this makes her more aware of the environment around her. For example, she starts to notice small changes in the forest that she might have overlooked as a human - shaped witch.
