For their relationships, it could be that Snape initially resents having to work with Harry in any way related to Flamel. However, as they encounter challenges together, such as dark magic threats trying to stop them from reaching Flamel's secrets, Snape realizes that Harry is more than just James Potter's son. Harry, on the other hand, begins to understand Snape's past and the reasons for his coldness. Flamel, with his long life experience, could share stories that make Snape and Harry reflect on their own lives and relationships.
A possible plot could involve Harry, in search of a way to destroy Horcruxes more effectively, seeking out Nicolas Flamel with Snape's begrudging help. Flamel, being an ancient and wise alchemist, has knowledge that could potentially lead to a new method of Horcrux destruction. Along the way, Snape and Harry start to understand each other better as they face various challenges together.
Obviously, Harry Potter and Nicolas Flamel are essential. But also including characters like Hermione Granger would be great. Hermione's thirst for knowledge would make her a perfect student of Flamel's teachings.
It could be in a magical alternate universe. Maybe a place where the rules of magic are different and allow for such a transformation.
Yes, there might be. The 'Harry Potter' universe is vast, and many fans create fanfiction exploring different relationships and scenarios. Nicolas Flamel is an interesting character in the series, so it's not surprising that someone would write a fanfic with this concept.
He is first mentioned when Harry gets a chocolate frog card in 'Harry Potter and the Philosopher's Stone'.
Nicolas Flamel is first mentioned in 'Harry Potter and the Philosopher's Stone'. In the story, it is through the discovery of his name on a chocolate frog card that Harry and his friends start to learn about him. He is an important figure as he is the creator of the Philosopher's Stone, which is a central element in the plot of this first book in the series.
In some fanfics, Nicolas Flamel might be reimagined as a time - traveling character who goes back in time to meet a young Harry Potter. He could then influence Harry's life in ways that change the course of the entire Harry Potter story.
The idea of Flamel's influence on the wizarding world is also common. His knowledge and power are so great that fanfictions may show how he affected events in the past, present, or future of the wizarding world. For example, some fanfics might suggest that he had a hand in the founding of Hogwarts or in the development of certain spells.
The relationship can be developed by having Snape protect Harry in unexpected ways. Maybe in a fanfic, there's a plot where some dark wizards are after Harry. Snape, secretly, uses his skills to keep Harry safe. Later, when Harry discovers this, Snape has to explain his actions. This explanation can be a turning point where they start to trust each other more. Snape can then start to offer words of comfort based on his understanding of Harry's situation. They could also start to work together on some small tasks, like researching a new potion that might help Harry in his fight against the dark side, which further cements their relationship.
