Some writers use it as a source of power. For example, they might write that Harry can draw on the magic that was used to create the scar to defeat his enemies. It's like his scar becomes a well of untapped magic.
In this fanfiction, the 'death in his scars' could potentially symbolize the many near - death experiences Harry has had throughout his life. Each scar might represent a moment when death was close, and it could also be related to the idea that Voldemort's attempts on his life, which left the scars, are a form of death lingering within him. It could add a very dark and deep layer to Harry's character, showing how he has been marked both physically and psychologically by the threat of death.
Harry's scars are a physical reminder of his encounter with Voldemort as a baby. In the fanfic, they might be a symbol of his unique identity. It sets him apart from others and makes him the Boy Who Lived. When Snape sees them, it could be a reminder of the power Harry holds, which Snape might both fear and respect in a way.
In this fanfic, Harry's scars are more than just marks on his body. They are a link to his past, his identity as the Boy Who Lived. When the Weasleys see them, it's a moment of connection. The scars could represent the power of love and family that the Weasleys offer to overcome his past traumas. They also might serve as a contrast to the Weasley family's relatively more carefree and happy - go - lucky nature. By seeing Harry's scars, the Weasleys get a deeper understanding of the darkness that exists in the wizarding world and the sacrifices Harry has made. This could lead to them being more protective of Harry or getting involved in his battles in a more profound way.
Well, Hermione is known for her intelligence and rational thinking. When she sees Harry's scars, she might first try to analyze them. Maybe she'd wonder about the magic that caused them, and if there are any lingering effects. This could lead her to research more about dark magic or the spells that left those marks. At the same time, she'd also have an emotional response, perhaps feeling a bit of anger towards those who hurt Harry.
They might be shocked and sympathetic. The Weasleys are a kind - hearted family. When they see Harry's scars, which are symbols of his difficult past, they would likely show concern. For example, Mrs. Weasley might immediately fuss over him, asking how he got them and if they still pain him.
A unique interpretation could be that the scar is actually a key. In a fanfic, it might unlock an ancient magic that was sealed away long ago. This magic could be the key to finally ridding the wizarding world of all dark magic for good. Harry then has to go on a quest to figure out how to use this key - his scar - in the right way.
There could be a fanfic where Harry's scar is magically transferred to another character. This other character then experiences flashes of Harry's memories and feelings related to Voldemort. It creates a whole new dynamic as this character has to deal with the burden of Harry's past and the connection to the Dark Lord, while Harry has to figure out how to deal with the loss of this part of himself.
One great fanfic could be about how Harry's scar has a mind of its own and communicates with him in his dreams. It might show his scar as a sort of magical conduit to the Dark Lord's thoughts, but in a way that's different from what's in the original books.
