One interesting plot could be Severus initially struggling to connect with Harry. He might be overbearing in his attempts to protect Harry from the dark forces, given his own experiences. For example, he could be overly strict about Harry's magical studies, thinking it's the best way to keep him safe.
Another plot could involve Severus trying to make up for the years he wasn't there for Harry. He might take Harry on secret trips to places he knew from his own past, like the Forbidden Forest, to teach him about the hidden dangers and magic within. He could also introduce Harry to potions in a more personal and in - depth way, sharing his own knowledge and love for the subject.
There are many fanfictions that explore Severus Snape's father. Some might depict him as a cruel man who had a negative impact on Snape's childhood. In some fanfictions, he could be an absent figure, which might have contributed to Snape's rather solitary and often bitter nature.
One interesting plot could be Snape raising Harry while secretly training him in advanced potions and dark arts defenses. Harry would grow up with a different perspective on Snape, seeing him as a strict but caring father figure. Another plot might involve Snape having to protect Harry from other dark wizards who suspect Harry's true potential. This could lead to some intense magical battles and Snape using his knowledge and skills to keep Harry safe.
A really unique plot could be Snape adopting Harry during a time when Voldemort is still a threat. Snape has to balance protecting Harry from Voldemort's followers and also from the prejudice within the wizarding community. He might train Harry in Occlumency more intensively, and in the process, they develop a deeper understanding of each other. Harry starts to see Snape not as the mean professor but as a complex person with his own traumas and reasons for his actions.
Another plot could involve Severus training Harry to be a better Occlumens. As Harry delves deeper into this art, he uncovers some of his own hidden memories and emotions. This could lead to a better understanding between Harry and Severus as they share their experiences with mind - protecting magic. It also might put Harry in a position where he can better defend himself against Voldemort's attempts to invade his mind.
A theme of abuse or neglect often appears. Given Snape's rather troubled childhood that is hinted at in the original books, fanfictions may explore how his father's behavior, whether it was physical or emotional abuse or simple neglect, shaped Snape into the person he became. This can add a layer of understanding to Snape's complex character.
One common plot is the discovery. Harry might find out through some hidden letters or a magical revelation that Snape is his father. Another plot point could be the reaction of the wizarding community. Some might be shocked, while others might see it as a way to redeem Snape's image.
One interesting plot could be that Snape secretly follows Harry during a dangerous wizarding tournament task and intervenes when a dark creature is about to attack Harry without revealing his identity. This would add a layer of mystery and show Snape's hidden care for Harry.
Well, one interesting plot could be Harry seeing Severus in a new light. He realizes that Severus was actually a complex and misunderstood character. So, he decides to adopt him to give him a new start in life. Another plot might involve Severus initially being resistant to the idea of being adopted by Harry, but over time, he warms up to the concept as he sees Harry's genuine kindness.
One interesting plot could be Severus having to deal with Harry's fame at Hogwarts while trying to keep their new family relationship a secret. It adds a layer of mystery and tension.
Some unique plots include a fanfic where Snape and Harry are magically bonded and can feel each other's emotions. There's also a story where Snape is turned into a cat and only Harry can understand him, leading to some really interesting interactions. A different one is a fanfiction where Harry discovers that Snape was actually protecting him all along in a much more elaborate and secret way than in the original books, and they have to team up to expose a greater conspiracy within the wizarding world.
