In these fanfictions, Snape's character often develops from a seemingly cold and unfeeling person to someone with more depth. When he saves Harry, it starts to chip away at his facade. For example, he might initially save Harry out of obligation but as time goes on, he realizes he has a genuine care for the boy. This is different from his canon behavior where his feelings are mostly hidden.
One good example could be a fanfiction where Snape saves Harry from a dark wizard's attack during the Triwizard Tournament. In this fic, Snape might have been secretly following Harry out of his sense of duty to protect him. Another could be a story where Snape saves Harry from a dangerous potion experiment gone wrong in the Potions classroom. He uses his extensive knowledge of potions to counteract the harmful effects.
The idea of Severus Snape saving baby Harry Potter in fanfiction is really fascinating. It gives authors the chance to explore a lot of uncharted territory. Snape, who was so conflicted in the original books, can be shown as more of a hero in this scenario. It can also change the whole Hogwarts experience for Harry. Instead of the initial hostility between them, there could be a sense of respect or even a mentorship. And it might even affect the relationships Harry has with other characters, like the way he views the Slytherin house.
A lot of fanfic writers will create unique storylines for Snape's courtship. They might introduce an original character who manages to break through Snape's tough exterior. His courtship would then involve him struggling with his own insecurities and his reputation. This character might see the good in him that others overlook. There could be moments of tension and misunderstanding, but also deep, meaningful conversations as they get to know each other better.
Often in fanfiction, the ring can be a plot device. It could be that Harry Potter unknowingly has a connection to the ring, and Severus Snape has to keep it from falling into the wrong hands. This creates a situation where Snape has to protect both Harry and the ring, leading to some tense and interesting storylines.
One common theme is redemption. Snape's actions to save Harry are often seen as a way for him to atone for his past mistakes or his association with the Death Eaters. It gives him a chance to be a hero in his own right.
In some fanfictions, Snape might share some of his knowledge about the wizarding world's secrets with Harry. Maybe he tells Harry about certain spells or magical artifacts that could help Harry in his fight against Voldemort. This act of sharing knowledge is a way of being nice as it gives Harry an advantage in his battles.
In the canon story, Snape has a very complex and often antagonistic relationship with Harry. But in fanfictions where he saves baby Harry, it's a huge departure. Here, Snape starts off as a protector, which is completely different from his role in the books where he seems to begrudgingly help Harry at times. It also changes the power dynamics as Harry may grow up with a sense of debt or gratitude towards Snape, rather than the suspicion and dislike he had in the original.
One great fanfiction is 'The Prince's Tale Reimagined'. It delves deeper into Snape's relationship with Harry from Snape's perspective. Another good one is 'Snape's Redemption Arc'. It shows how Snape's actions throughout the series can be seen in a different light, with a focus on his complex relationship with Harry. And 'A Different Kind of Magic' is also a wonderful read. It creates an alternate universe where Snape and Harry have to work together more closely from an earlier point in the story.
One appeal is the novelty. It's not something you'd expect in the normal Harry Potter world, so it grabs attention. Fans like to see familiar characters in new and unexpected situations.
