Well, in this fanfiction scenario, Severus' personality would undergo a significant transformation. His typical bitterness might fade away as he focuses on Harry's growth and development. He would start to show more empathy, which is not something he often displays. He'd have to be more open - minded as well, because he's now responsible for a child with his own unique experiences and needs. For example, he might have to learn to tolerate Harry's more Gryffindor - like tendencies instead of always trying to enforce Slytherin values. This new role of being an adoptive father would make him a more complex and rounded character, with a heart that slowly unfolds as he bonds with Harry.
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.
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.
His personality also becomes more open. He has to communicate with Harry in a more honest and open way. He can't keep all his thoughts and feelings bottled up like he used to. He has to share his wisdom and experiences with Harry, which in turn makes him more approachable and less of the brooding, closed - off person he was before in the official story.
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.
In this scenario, Severus' character experiences a significant transformation. He has to shed his cold exterior to a large extent. He becomes a father figure, which means he has to be there for the boys emotionally. He starts to show emotions more openly, whether it's pride when they do well in their studies or worry when they are in danger. His sense of loyalty also shifts. Before, it was mainly towards certain people or causes, but now his loyalty is first and foremost to Harry and Draco. This new - found loyalty makes him a more rounded and likable character in the fanfiction, as he is no longer just the brooding potions master but a loving and dedicated father.
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.
Severus' character undergoes a major transformation. He begins to value relationships more, especially his newfound father - son relationship with Harry. He may start to interact more with the other students in a less intimidating way because he realizes that being harsh all the time isn't good for anyone, especially Harry. He also becomes more involved in the non - potions aspects of Harry's life at Hogwarts, like helping him with his other studies or dealing with bullying from other students. This shows a side of Severus that was previously hidden, a side that cares deeply for someone other than himself.
One possible plot could be that Severus discovers the extent of Harry's abuse at the Dursleys. He decides to take Harry in out of a sense of duty or perhaps a hidden soft spot for the boy. He then has to teach Harry about magic in a more personal and nurturing way, different from Hogwarts. They might also face opposition from the wizarding community who question Severus' motives.
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.
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.
The relationship may become more complicated. Severus might struggle with his own emotions. He might feel an urge to protect Harry from this fictional abuse, but at the same time, he has to deal with his long - standing animosity towards Harry. So, it could lead to a very strange and tense dynamic between them, with Severus trying to balance his new - found protectiveness and his old grudges.
