Well, it could be that in this fanfiction, Snape is written in a way that endangers Harry's friends. Harry is very protective of his friends, so if Snape is portrayed as harming them in some way, Harry would likely try to destroy whatever it is that's causing the threat. Also, it could be related to some prophecy or hidden knowledge in the fanfiction that makes Harry believe Snape has to be stopped.
It could make their relationship extremely hostile. Snape would likely be very angry at Harry for destroying something related to him, which would further strain their already tense relationship.
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.
I'm not sure specifically as there could be many different interpretations in fanfiction. It might involve Harry making choices that have dire consequences for the future in the fictional wizarding world, perhaps through the misuse of magic or making wrong alliances.
There very well could be. Fanfiction writers often like to explore unusual crossovers. Since both Harry Potter and Thanos are extremely popular in their respective franchises, it's a ripe area for creative exploration. However, the quality and availability can vary greatly depending on the fanfiction platforms you search on.
One possible plotline could be that Snape, in his secret attempts to rescue Harry, starts to see a different side of him. Maybe during a dangerous situation in the Forbidden Forest, Snape saves Harry from a dark creature. As they spend time together afterwards, they begin to understand each other's pain and pasts, and slowly romantic feelings start to develop.
No, it's not common. Usually, fanfiction focuses on positive relationships between characters, especially Harry and the Weasleys who are often portrayed as a close - knit family. So this would be a rather unusual and dark theme.
Ron and Hermione would most likely be his allies. They've always been by Harry's side through thick and thin. In this situation, they would use their respective skills, Ron's loyalty and Hermione's vast knowledge of magic, to support Harry in his mission to destroy Snape.
Ron and Hermione are almost surely his allies. They've always been by his side through thick and thin. Hermione's vast knowledge of magic and Ron's loyalty and courage would be invaluable in a mission to destroy the Ministry.
