One good example could be a fanfic where Snape's daughter becomes friends with Harry. She might help him understand Snape better. For instance, she could reveal some of her father's past that makes Harry see Snape in a new light, like his hidden acts of kindness during the war. Another example could be a story where she has her own adventures at Hogwarts while being in the middle of the conflict between Snape and Harry's side. She might try to bridge the gap between them.
There's a fanfic where Snape's daughter is a brilliant potions student like her father. In this story, she teams up with Harry Potter to find a cure for a mysterious illness that is affecting the wizarding world. Their partnership starts off rocky because of the history between Harry and Snape, but as they work together, they begin to trust each other. This fanfic shows how the two characters can overcome their differences through a common goal.
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.
This fanfiction idea also opens up new storylines regarding Harry's heritage. If she is Snape's daughter, then she might inherit some of his skills in potions and the Dark Arts. It could also lead to a different take on the prophecy. Instead of being the 'Chosen One' in the same way as in the original, it could be related to her connection to Snape and the secrets he has been keeping.
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.
Perhaps she has a special magical ability that is different from her father's. This ability could draw the attention of both good and bad forces. She has to learn to control it while also dealing with the expectations placed on her because of her father. For example, if she has the ability to communicate with magical creatures in a way no one else can, she might be pressured to use it for the benefit of the school or be targeted by those who want to use it for evil.
The plot could involve Snape trying to protect his daughter from the dark forces in the wizarding world without revealing his true relationship to her. He might give her special potions or spells to help her in her adventures at Hogwarts. And as Harry grows, she might start to look more like Snape, which causes some confusion and speculation among the other characters. This could lead to a series of events where Harry slowly uncovers the truth about her father.
One example could be 'The Mentor and the Student'. In this fanfiction, Snape focuses on mentoring Harry in potions without any inappropriate undertones. Another is 'A Different Bond' which explores their relationship in a strictly platonic way, centered around their mutual goal of defeating Voldemort. And 'The Unlikely Alliance' shows them working together for the good of Hogwarts, with no slash elements.
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.
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.
One great Snape fanfiction is 'The Prince's Tale Redux'. It delves deeper into Snape's relationship with Lily. It shows his internal struggles and how his love for her influenced his actions throughout the series. It gives a more in - depth look at his character than what was shown in the original books.
