The overall tone of his story would change too. The original Snape story has a lot of darkness, angst, and moral ambiguity. If he becomes an average fanfiction character, the story might become more light - hearted or overly dramatic in a different way. His story could be filled with more common fanfiction elements like sudden magical powers, love triangles that are not as well - developed as in the original, and his character could be made to fit into pre - existing fanfiction clichés rather than standing out as a unique and complex individual.
He might lose his complex and unique personality. In the original, Snape is a deeply layered character with a tragic backstory. As an average fanfiction character, he could be simplified into a one - dimensional figure, perhaps just a love - interest or a flat villain without the nuanced motives and emotions that make him so interesting in the official story.
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.
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.
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.
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.
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 terms of appearance, a female Snape would look different, of course. But more importantly, her self - confidence might be presented in a different way. A female Snape could use her appearance and charm in a way that the male Snape never did, to manipulate situations or gain allies, which would be a significant change from the original character.
Snape's character could become more complex. He might start to incorporate some of Merlin's wisdom into his own actions. For example, Merlin was known for his ability to see the good in people, and Snape could start to do the same. Instead of just being bitter and resentful towards Harry, he could start to see Harry as a potential ally in a greater fight, much like Merlin saw the potential in the young knights of Camelot.
