Yes, there are likely some out there. Fanfiction often explores unique and unexpected relationships. Some writers might be intrigued by the idea of Harry being Snape's son and delving into the 'dark side' aspects could involve exploring Snape's more complex and perhaps morally ambiguous nature, as well as how that would impact Harry's character and his journey in a different way than in the original story.
I'm sorry, I can't directly recommend a specific one. But you can try searching on fanfiction websites like Archive of Our Own or FanFiction.net. Use the keywords 'Harry is Snape's son' and 'dark side' to narrow down your search. There are likely to be some interesting stories out there waiting for you to discover.
One great fanfiction that explores the dark side in the Harry Potter universe is 'The Darkening of Hogwarts'. It delves into what would happen if dark magic seeped deeper into the school. The characters are faced with moral dilemmas and the story shows how the allure of the dark side can be both tempting and terrifying.
Most likely not. Popular fanfictions in the Harry Potter universe tend to focus on more relatable themes like relationships, adventures, or character backstories. This 'snot' - related concept is so far from the norm that it would probably only appeal to a very niche group, if any at all.
Well, without actually reading this specific fanfiction, it's hard to say precisely. But it could potentially be a humorous or dark exploration of the Harry Potter universe. Maybe it's a satirical piece that uses the idea of Snape's snot as a symbol of something, perhaps his disdain for Harry or some other complex emotion in a really warped way.
If the dark side saves Harry in fanfiction, it could open up a whole new world of story possibilities. Maybe it would involve Harry having to confront his preconceived notions about good and evil and find a way to balance the powers within him.
In some fanfiction, the dark side might help Harry by giving him unique powers. For example, dark magic could offer him abilities that are not available in regular magic, which he can then use to fight against stronger enemies.
Dumbledore could be seen as the main antagonist from Harry's new perspective on the dark side. Dumbledore represents all that is good in the wizarding world, and if Harry has turned to the dark, Dumbledore would be the one trying to stop him, to bring him back to the light. So in this context, Dumbledore becomes the opposition that Harry has to face.
The dark side can offer Harry a different perspective on magic. In fanfiction, this could mean that he starts to see the limitations of traditional 'good' magic and finds new ways to combine or manipulate magic by incorporating elements from the dark side. This can make his magical abilities more versatile and powerful.
Well, perhaps Harry gets tired of being constantly in danger and feeling unappreciated in the wizarding world. He might be lured by the Dark Side with promises of power and safety. Voldemort could offer him a place by his side, showing him a different view of magic that seems more appealing in a warped way.
