Another plotline might involve Harry facing the challenges of being a Snape in a world that still has some lingering prejudice against Snape's actions during the war. He would have to prove himself not only as a powerful wizard but also as someone different from the image people have of his father. This could create a lot of internal conflict for Harry as he tries to carve out his own identity while still respecting his father's legacy.
One interesting plotline could be Harry growing up with Snape's guidance and inheriting his potions skills at an early age. He might have a different dynamic with the other Hogwarts students, being more of an outcast due to his connection to the often - misunderstood Snape.
One interesting plotline could be Snape and Harry having to work together on a secret project for Dumbledore. They start off distrusting each other but as they face challenges, they gradually become friends. For example, they might be researching a powerful dark magic spell that Voldemort is after, and in the process, they learn about each other's past traumas and start to empathize.
Some fanfictions have a plotline where Snape survives the Battle of Hogwarts and he and Harry have to deal with the aftermath together. They might have to face the wizarding community's reaction to Snape's past actions and also work on rebuilding Hogwarts. There are also stories where Harry, while still at school, starts to understand Snape's difficult position between Dumbledore and Voldemort and tries to help him in some way, which creates a whole new dynamic between them.
Yes, in certain fanfictions. Fan writers like to play with the established relationships in the original 'Harry Potter' series. They might decide to make Harry Snape's son to add a new layer of drama and mystery. For example, it could change the way we view Snape's actions throughout the series, as his protectiveness towards Harry could then be seen as a fatherly instinct.
Another idea is that after Snape sacrifices himself, his spirit somehow remains bound to Harry. He becomes a sort of spiritual guide for Harry, like a father figure from beyond the grave. Harry has to learn to communicate with Snape's spirit and in the process, they heal old wounds and form a deep bond.
One possible plotline could be that Harry breaks a major Hogwarts rule, like sneaking into the Forbidden Forest. Snape catches him and decides that a severe punishment is in order, which in this case is spanking. Another could be that Harry fails a very important Potions test repeatedly, and Snape, frustrated with his lack of progress, resorts to this extreme form of discipline. However, these are all just fan - created ideas and not part of the official story.
One interesting fanfiction could be about Snape secretly mentoring Harry outside of Hogwarts. In this story, Snape realizes the importance of Harry's role in the wizarding world and decides to give him extra training in potions and defense against the dark arts without Dumbledore's knowledge. It shows a different side of their relationship, less adversarial and more collaborative.
There are fanfictions that focus on Snape's role in the wizarding war from a different perspective. For example, how he secretly influenced certain events to protect Harry without anyone really knowing. He could have been involved in undercover operations that are not mentioned in the original books.
A great plotline might be Snape teaching Lily Luna Potter some of his signature potions in a private tutoring session. Through these interactions, they develop a unique bond. Or perhaps Lily Luna Potter gets into a dangerous situation, and Snape is the only one who can save her because of his in - depth knowledge of the dark arts. This would create a scenario where she has to trust him completely, despite his often - misunderstood reputation.
Perhaps a plot where Severus discovers his demigod heritage and has to balance it with his life at Hogwarts. He could struggle with how to use his new - found powers without drawing too much attention, while also dealing with his complex relationships with other characters like Harry Potter.
One interesting plotline could be exploring Snape's early interactions with the Marauders. Maybe it shows how his enmity with them truly began. For example, it could focus on a particular incident in their school days that was a turning point.
