Well, it would be a very interesting turn of events. Snape adopting Harry would mean that Harry would be exposed to a whole different set of values. Snape, with his own grudges and loyalties, might teach Harry to be more cautious and less trusting. In the magical world, this could have both positive and negative impacts. Harry might not be as quick to make friends like he did at Hogwarts in the original story. However, he could also be more self - reliant. Snape would probably also keep Harry away from Dumbledore to some extent, which would change the power dynamics and the information flow that Harry had access to in the original plot.
If Severus Snape adopted baby Harry Potter in fanfiction, it would completely transform the story. Firstly, Harry would grow up in a very different environment. Snape, being a strict and complex character, would likely raise Harry with high expectations in academics, especially in Potions. Harry might become more introverted under Snape's influence as Snape isn't the most sociable person. Also, Snape's knowledge of the Dark Arts could either protect Harry better or put him in more danger, depending on how Snape chose to use it in Harry's upbringing. The relationship with the other characters would be different too. For example, Harry's relationship with the Weasleys might not be as strong as in the original story since he would be growing up in a more isolated environment with Snape.
Severus would likely become more protective. His personality would shift from being mainly focused on his own grudges and potions work to being centered around Harry's well - being. He might also become a bit more open - minded as he has to consider Harry's needs and wants, which could be different from his own. For instance, he may have to tolerate Harry's love for flying, even though he himself may not be into it. And over time, he might develop a sense of humor as he deals with Harry's childish antics.
Snape's character changes in his relationship with others too. He becomes more involved with the Hogwarts community as he is now responsible for Harry. He might start to collaborate more with other teachers, like McGonagall, who he previously had a rather cold relationship with. His attitude towards the students also changes as he realizes that they are just kids trying to find their way, much like Harry. This is a big shift from his usual strict and often unforgiving self.
Snape's personality would likely soften. He'd have to be more patient and understanding. Instead of just being the strict and often sarcastic Potions master, he'd become more nurturing. He'd still have his sharp edges, but around Harry, he'd show more kindness and care as he takes on the role of a guardian.
The relationship would start off rocky. Snape would be resistant to Harry's kindness as he has always seen Harry as James Potter's son. But Harry's persistent efforts to understand and help Snape would gradually break down Snape's walls.
Snape's parenting style would likely be strict. He is a no - nonsense person, so he would expect Harry to follow rules precisely. He would probably be very demanding when it comes to Harry's studies, especially in Potions. However, Snape also has a deeply emotional side, so he might be protective of Harry in his own way, though he would rarely show it outwardly.
In such a fanfiction, Harry might see the potential in young Severus that others overlooked. He could protect Severus from the bullies at Hogwarts. Harry, having experienced his own share of hardships, would understand Severus's situation to some extent and try to give him a better childhood, perhaps even guiding him to use his magic in a more positive way.
He would become more nurturing. Usually, Severus is seen as cold and aloof, but with Harry in his care, he'd have to show more warmth. He might still be strict, but it would be out of love for Harry's well - being rather than just being his usual harsh self.
Well, it would change the story a great deal. Firstly, Harry would have a more stable home environment with Severus as his guardian. He wouldn't be so alone at the Dursleys'. Draco, on the other hand, might learn different values from Severus rather than just pure - blood supremacy from his family. And Hermione would have an adult figure in the wizarding world who truly understood her thirst for knowledge. The whole dynamic between the three of them would shift from rivalry to more of a sibling - like relationship under Severus' care.
Snape would become more nurturing. He's used to being cold and distant, but with a baby to care for, he'd have to soften. For example, he'd learn to comfort Hermione when she cries.
Snape's character could become more calculating and cold - hearted. Tom Riddle is not exactly a nurturing figure, and being raised by him would expose Snape to a world of power - seeking and self - interest. Snape may lose some of his capacity for love and affection that he had for Lily in the original story. He would be more focused on achieving power and status within Riddle's regime. His relationships with other characters would be more transactional. For instance, he would not form the same kind of complex relationship with Narcissa Malfoy as he did in the original story because his priorities would be different, being centered around Riddle's goals rather than his own personal loyalties and emotions.
