One reason could be that he sees her intelligence and potential. Snape has always had a soft spot for those who are brilliant in potions and magic, and Hermione is top - notch in that regard. He might also recognize her determination and how she's often an outcast among her peers in a way, just like he was. So, he feels a sense of kinship and thus protectiveness towards her.
Perhaps it's because of Hermione's role in the wizarding world's future as Snape might perceive it. She is a key figure in the fight against the Dark Arts. Snape, being someone who has his own complex relationship with the fight against evil, might feel the need to protect her to ensure the good side has a better chance of winning. He could also be reminded of Lily by Hermione's courage and loyalty, which stirs up his protective instincts.
In fanfiction, Snape may feel protective of Hermione because she challenges the status quo in Hogwarts. Snape, who has always been a bit of an outsider himself, might admire her for not being afraid to speak her mind and go against the traditional ways. This admiration could translate into protectiveness. Also, her thirst for knowledge and eagerness to learn might remind Snape of his own younger self, and he doesn't want her to be crushed by the more rigid elements of Hogwarts society.
Well, it could be that the fanfiction author has created a unique backstory. For example, Snape could have saved Hermione's life at some point in the past, and she now has this deep - seated sense of security around him. Also, he might be a source of knowledge for her, and his presence, while initially intimidating, becomes reassuring as she realizes he won't let harm come to her in matters related to magic and the school.
Perhaps it's because Snape is a complex character in the original story. Fanfictions might explore his character in ways that make Hermione seem protected in those fictional scenarios. For example, some fanfictions could depict Snape using his knowledge and power to shield Hermione from various threats within the magical world they inhabit.
At first, Hermione might be suspicious of Snape's new - found protectiveness. But as time goes on, she starts to see that he has good intentions. Snape, on the other hand, gradually warms up to Hermione more and more, sharing his knowledge and advice with her.
Well, in some fanfictions, Snape might be protective of Harry because he sees a lot of Lily in Harry. Lily was Snape's long - loved friend, and Harry is her son. So that connection makes Snape feel an urge to protect Harry from harm, despite their often - rocky relationship in the original story.
Snape might be protective of Draco in fanfiction because in the original series, Snape has a certain loyalty to the Slytherin house. Draco is a young Slytherin, and Snape could see a bit of his own past self in Draco. Also, Snape was tasked with some difficult and dangerous missions by Voldemort. He might want to protect Draco from getting too deeply involved in Voldemort's dark plans to spare the boy from a similar fate as his own.
Moony might be protective of Hermione because he has a strong sense of justice. In the wizarding world, Hermione is a Muggle - born, and she often faces discrimination. Moony, being a member of the Order of the Phoenix, is against all forms of prejudice. He would naturally want to protect her from any harm, whether it's from Death Eaters or just general bigotry within the wizarding community. Also, Hermione's intelligence and her role in fighting against the dark forces make her an important asset, and Moony would understand the need to safeguard such a valuable ally.
One reason could be that they see her intelligence as an asset. Hermione is known for her brilliant mind, and Slytherins, who value cunning and resourcefulness, might respect that. They could also recognize her strength in the face of adversity and be drawn to protect her as a way to show their own growth beyond the typical Slytherin - Gryffindor rivalry. In some fanfictions, a Slytherin might have a personal connection or debt to Hermione, which leads to their protective nature towards her.
Maybe it's because he admires her intelligence. Hermione is known for her vast knowledge of magic, and Charlie, who has his own area of expertise with dragons, might respect that. He sees her as someone worth protecting because she could contribute a great deal to the wizarding world, and he doesn't want to see that potential lost.
In many fanfictions, Remus might be protective of Hermione because he sees her great potential and intelligence. He could also feel a sense of duty as an older, more experienced wizard. Additionally, he may have witnessed some of the hardships she has faced at Hogwarts and wants to shield her from further harm.
In fanfiction, Harry might be protective of Hermione because of their deep friendship. They've been through so many dangerous adventures together in the original series. Harry values Hermione's intelligence and loyalty, and he doesn't want to see her get hurt. It could also be that in some fanfiction, there are new threats or situations that make him feel the need to be extra protective.
