The unlikely relationship might evolve when Voldemort recognizes something unique in Hermione and decides to mentor her secretly. This could result in a divided wizarding community, with some fearing her newfound influence and others seeing it as a potential for change. But it's all up to the author's imagination!
At first, their relationship is likely to be very tense. Harry is used to seeing Snape as an enemy. But as Snape starts to mentor him, Harry begins to see Snape's knowledge and skills. Snape, on the other hand, might start to see Harry as more than just James Potter's son. As time goes on, they develop a mutual respect. Harry respects Snape's magical abilities and Snape respects Harry's determination. Eventually, they could become something like a reluctant teacher - student duo that also has elements of a father - son relationship, especially considering Snape's love for Harry's mother.
Their relationship develops in a rather interesting way. Snape, being a strict mentor, forces Harry and Draco to look past their differences. Harry begins to understand Snape's past and the reasons for his actions, which in turn makes him more open to Draco. Draco, who has always been in Snape's good graces to some extent, has to adjust to sharing Snape's attention with Harry. This causes some initial jealousy but later leads to a sort of rivalry - turned - friendship as they both grow under Snape's tutelage.
It could start with a lot of animosity on Harry's part, but as he is trained, he might start to see Voldemort in a different light. Maybe he begins to understand Voldemort's motives, though not necessarily agreeing with them.
The wizarding world would be in shock. The two most polarizing figures being mates would shatter the existing power dynamics. The Death Eaters might split, some following Voldemort's new path with Harry, while others would rebel. The Order of the Phoenix would also be divided, with some believing in the power of love and this strange bond, and others seeing it as a trick by Voldemort.
Well, the pure - blood families who were on the fence about Harry might finally accept him wholeheartedly. They would see that he was the one who could truly rid the wizarding world of Voldemort. However, there would also be those who would be critical. Some of the more traditional wizards and witches might think that using a shooting method was too violent and un - wizard - like. They might worry that this sets a bad precedent for future conflicts in the wizarding world. But overall, the general public would be relieved that Voldemort was finally gone and would likely celebrate Harry as a savior.
At first, it's often rocky. Harry is used to seeing Snape as an enemy, so he's very distrustful. Snape, on the other hand, has his own grudges against Harry's father. But as the mentoring progresses, Harry starts to see Snape's knowledge and skills. For example, Snape might teach Harry a difficult potions technique, and Harry realizes Snape is a great teacher. Snape, in turn, may start to see Harry as more than just James Potter's son, and their relationship slowly improves.
It could become very close and trusting. They'd know each other inside out and have a deep bond from childhood.
If Harry Potter is a vampire and meets Voldemort, it could send shockwaves through the wizarding world. Wizards might start to question the boundaries between different magical beings. For instance, they might wonder if more vampires could become involved in wizarding affairs. This could lead to new laws or regulations regarding vampires.
It might start with Voldemort's initial curiosity. He realizes Harry is more than just a threat. So he begins to observe Harry closely. As time goes by, Voldemort may start to feel a strange sense of connection, like he's the only one who truly understands Harry's power.
He could bring about major changes in the way magic is understood. His time - related powers might introduce new spells or magical concepts that are based on time manipulation. For example, a spell that can age an object rapidly or restore it to its former state in time.
