If Snape is a king in the fanfiction, his personality would transform in multiple ways. He would have to be more diplomatic. In the original story, he could be quite curt and sarcastic, but as a king, he would need to smooth over relations with other magical entities. His loyalty, which was mainly to Lily in the original, would now be extended to his entire 'kingdom'. He would be more outward - looking, thinking about the greater good of his realm rather than just his own personal vendettas. He might also become more patient, as ruling requires dealing with a lot of different personalities and situations.
As a king, Snape's personality would likely experience a significant shift. He would be more authoritative. In the normal Hogwarts setting, he was often at the mercy of Dumbledore's orders and the politics of the school. But as a king, he would be the one giving the orders. His introverted nature might still be there, but it would be masked by a more regal and public - facing persona. He would need to inspire loyalty from his subjects, so he might show more kindness and understanding, especially to those who are loyal to him. He would also be more decisive, knowing that his decisions affect not just himself but an entire 'kingdom' of people and magical creatures.
Snape might become more confident. As a king, he would have to take charge and make decisions without hesitation. His usual brooding and self - doubting nature might be replaced by a more assertive and commanding personality. He would also likely be more protective of his 'kingdom' or those under his rule, which could show a more noble side of his character.
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 these fanfictions, Snape often becomes more self - reflective. He starts to realize the full extent of his actions and how they've affected others. For example, he might come to see how his treatment of Harry was unfair. He also becomes more open about his emotions, which was something he always hid before.
Snape's deaged personality could also be more impulsive. Without the restraint of his adult self, he might act on his emotions more quickly. For example, if he felt wronged, he might lash out immediately instead of plotting a long - term revenge like his older self would do. Also, he could be more curious about the world around him, eager to explore magic in a new way that his older self had forgotten due to years of being jaded.
Snape would likely become more nurturing. Instead of just being the strict and often cold Potions master, he would have to show a softer side to take care of Harry. He might be more patient as he guides Harry through his magical education and daily life.
Snape's personality might soften. He's used to being cold and distant, but taking in Hermione could bring out his protective side more. He'd become more patient as he guides Hermione through her troubles.
Snape's character often becomes more open - minded. In many such fanfictions, being around the Marauders, who are generally more carefree and adventurous, forces Snape out of his shell. He starts to see things from different perspectives, rather than just being the brooding loner he was originally.
As a wolf Animagus, Snape might be more in touch with his primal instincts. His usual guarded and calculating personality could be tempered by the wild nature of the wolf. He may be more impulsive in his actions, acting on instinct rather than over - thinking every move like he does in his human form.
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.
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.
He might become more arrogant. With royal status, he could develop a sense of superiority over others. For example, he might look down on his students more than he already does in the original story.
