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'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.
One common portrayal in fanfiction is that of Snape being suspicious of Tom Riddle when he was still a student at Hogwarts. Snape, with his sharp intellect, might notice things about Riddle that others overlook, like his unusual interest in certain dark spells or his ability to manipulate those around him.
In fanfiction, Tom Riddle and Severus Snape are often depicted in complex relationships. Riddle, as the future Voldemort, represents pure evil. Snape, on the other hand, is a more morally ambiguous character. Fanfictions might explore how Snape would react to the younger Riddle at Hogwarts. Maybe Snape would be one of the few to see the darkness in Riddle early on.
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.
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.
One great fanfiction could be where Tom Riddle discovers Severus Snape's hidden potential in potions early on. It might explore how Riddle, with his ambition, tries to mold Snape into a more powerful ally. This could lead to a complex relationship filled with power dynamics and mutual respect for each other's skills.
In some fanfics, Snape and Riddle are portrayed as having a mentor - mentee relationship in reverse. Riddle, being older and more powerful, could have influenced Snape in ways that are not obvious in the original books. For example, in 'The Influence of Riddle on Snape', we see how Snape's early interest in the Dark Arts might have been a result of Riddle's presence at Hogwarts, even if they never directly interacted much.
One great Severus Snape and Tom Riddle fanfiction is 'The Darker Path'. It delves into their time at Hogwarts, exploring how their different natures interacted. Snape's complex relationship with the Dark Arts, influenced by Riddle, is a central theme. The story is full of intrigue and mystery.
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.
