In certain fanfic scenarios, Snape may feminize Harry by influencing his appearance. Maybe he gives advice on clothing or grooming in a way that makes Harry seem more feminine. For instance, suggesting a more delicate style of robes or a different hairstyle that is associated with femininity in the wizarding world.
Some fanfics might have Snape feminize Harry in terms of his behavior. He could push Harry to be more nurturing, like taking care of magical creatures in a more motherly way rather than just being the heroic adventurer. This could involve teaching Harry how to soothe and tend to the needs of the creatures, which is a trait often linked to femininity.
One reason could be for the sake of character exploration. Writers want to see how Harry would develop if he embraced different, often 'feminine' qualities. It adds a new dimension to his character.
A great fanfic could involve Harry being bullied by some Slytherins and Snape steps in. He takes Harry to his office and instead of scolding him, he offers him a cup of tea. Snape then tells Harry about how he himself had to deal with difficult situations at Hogwarts when he was young. By opening up like this, Snape comforts Harry and makes him realize that everyone has their own battles. Harry leaves the office feeling more confident and less alone.
One great example could be 'A Different Sort of Guidance'. In this fanfic, Snape takes Harry under his wing in a more private and reluctant way. He starts to teach Harry about advanced potions and also imparts some of his knowledge about the Dark Arts, not to encourage Harry to use them, but to understand the enemy better. Another is 'Snape's Unlikely Apprentice', where Snape is forced to mentor Harry due to a magical decree, and their relationship develops from one of mutual dislike to grudging respect.
One good example could be those that explore Harry's darker side in his interactions with Snape. For instance, a fanfic where Harry, influenced by dark magic, challenges Snape's authority in a more menacing way. Another is a story where Harry discovers some dark secrets about Snape and uses that knowledge to manipulate situations in Hogwarts. There are also fanfictions that show a more complex relationship between them, with Harry having a darker personality due to the traumas he has faced, and Snape being caught in the middle of Harry's internal struggle.
One example could be that Snape secretly helps Harry with his Potions work. He might leave some useful hints or books where Harry can find them. Maybe he gives Harry a potion ingredient that is hard to get when he sees Harry struggling to complete a difficult potion recipe.
One great fanfic is 'The Prince's Tale Continued'. It delves deeper into Snape's life after the events of the original series. It shows his struggle to come to terms with his past and his role in the wizarding world. Another good one is 'Snape's Redemption'. This fanfic focuses on how Snape tries to make amends for his past actions towards Harry and the others. It gives a more in - depth look at his complex character.
One great fanfiction where Snape helps Harry Potter is 'The Unseen Bond'. In this story, Snape secretly protects Harry from a new dark threat at Hogwarts. He uses his knowledge of the Dark Arts to counter the enemy's spells. This shows a different side of Snape, one that is more benevolent towards Harry.
One interesting 'Harry Potter and Snape fanfic' story could be about Snape secretly mentoring Harry outside of Hogwarts. In this fic, Snape realizes the importance of Harry's role in the wizarding world and decides to give him extra training in potions and dark arts defense, away from the prying eyes of the other teachers and students.
I really like 'The Mentor Snape Never Thought He'd Be'. In this story, Snape is forced into mentoring Harry due to a magical bond. As they work together, they start to understand each other's motives better. Snape realizes Harry is not just James Potter's son, but his own person. And Harry sees that Snape has more to him than just being a grumpy professor. It's a story that shows how their relationship could have developed in a different way in the fanfiction world.
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.
