There's a fanfic titled 'Snape's Redemption in Harry's Abuse'. This story focuses on how Snape, who has his own complex past with Harry's father, realizes that Harry is a victim of constant abuse. He decides to use his position as a teacher and his skills in potions and magic to keep Harry safe. It delves deep into the relationship between Snape and Harry, exploring themes of forgiveness and second chances.
I really like 'Under Snape's Wing'. It starts with Harry being in a really bad state from the abuse he has endured. Snape, with his own set of issues, takes Harry in. The story follows their journey as they learn to co - exist, with Snape slowly becoming a protector figure for Harry. It's full of heart - warming moments as well as some tense ones as they navigate their new relationship.
I'm not sure of a specific title, but generally in such fanfics, the abuse Harry faces in Slytherin could be psychological, like being ostracized or bullied verbally. Some might explore how he tries to keep his Gryffindor values while dealing with this difficult situation in a house known for its more cunning nature.
One popular fanfiction with this concept might be 'The Unthinkable' (this is just an example, not an actual well - known title with this exact plot). In many such fanfictions, it explores how Snape's personality would influence Harry's upbringing. Snape, being strict yet intelligent, could instill in Harry a different set of values compared to the Dursleys or even Dumbledore's influence in the original series.
Their relationship usually starts with Snape's reluctant interference in Harry's situation. He might initially be motivated by his own complex feelings towards Harry's parents. As he starts to save Harry from the abuse, Harry is initially suspicious but gradually becomes grateful. This leads to a slow thawing of the coldness between them.
One great fanfiction in this vein is 'The Slytherin Heir' where Harry, having endured abuse, is sorted into Slytherin. It delves into his complex relationships with his housemates and how he overcomes the stigma associated with Slytherin. The story shows his growth and development as he uses his Slytherin cunning to face the challenges in the wizarding world.
One example could be a story where Harry is verbally abused by some of his classmates in Hogwarts. Hermione steps in, using her quick wit and magic skills to defend him. She might cast a spell that makes the abusers' voices disappear when they try to say mean things. In this fanfiction, Hermione becomes Harry's protector, not just from the bullies but also from his own self - doubt that the abuse has caused.
One common element is the exploration of Snape's hidden kindness. Usually, in the original series, Snape is often portrayed as cold towards Harry. But in these fanfictions, his true, more compassionate self emerges when he realizes Harry's situation. Another element is the in - depth look at Harry's trauma from the abuse. It shows how it affects his studies, his relationships with others at Hogwarts, and his overall mental state.
In some versions, Snape might notice Harry's withdrawn behavior or signs of physical harm during Potions class. Maybe Harry flinches when someone gets too close, which makes Snape suspect something is wrong.
One common plot could be Harry being physically or emotionally abused at the Dursleys' and Snape secretly observing. Then, Snape steps in when the situation becomes dire. For example, he might use his magic to scare off the Dursleys when they are about to seriously harm Harry. Another plot could involve Snape finding out about Harry's internal struggles due to the abuse, like his self - doubt and fear. Snape, in his own way, helps Harry build confidence and overcome his trauma. He might start by teaching Harry some advanced magic in private, which not only gives Harry new skills but also a sense of self - worth.
I'm not sure there are a lot of such specific fanfictions, but you could start by looking on major fanfiction platforms like Archive of Our Own. Try searching for the exact phrase 'Harry turned vampire Snape mate' in the search bar. There might be some hidden gems there.
