In the original series, Harry doesn't kill Umbridge. So this fanfic takes a very different turn right there. In the original, Umbridge is eventually removed from Hogwarts in a more traditional way, through the combined efforts of the students and the return of Dumbledore. But in the fanfic, Harry taking her life is a huge deviation from the non - violent and more rule - abiding nature of the main character in the original series.
Yes, there might be some out there. However, it's important to note that in the original 'Harry Potter' series, Harry is not one to kill easily. But in fanfiction, authors can take creative liberties. You can search on popular fanfiction platforms like Archive of Our Own. Some fanfics might explore a scenario where Umbridge's extreme actions push Harry to the limit, creating a really engaging and dark story.
One possible motive could be a misunderstanding. Maybe Snape is framed for something really bad, like a dark magic plot against Hogwarts. Harry, in his haste to protect the school and his friends, believes Snape is guilty and takes drastic action. Another reason could be if Snape accidentally endangers someone Harry loves dearly, like Ginny or Ron, and Harry's emotions get the better of him in the heat of the moment.
In the fanfic, perhaps Harry had reached his limit with Umbridge's blatant disregard for the rights and well - being of the students and magical creatures. She was a symbol of the corrupt Ministry at that time. Harry, having a strong sense of justice, could no longer tolerate her presence and actions, especially after seeing how she treated his friends and those he cared about at Hogwarts.
One possible plot development could be that Harry kills Umbridge in self - defense. Maybe she attacks him first with the intent to harm or kill, and Harry has no choice but to use lethal magic in return. This would then lead to a huge uproar in the wizarding world, with some believing Harry was right and others seeing him as a murderer.
Fred and George Weasley are also favorites. Their mischievous nature can be amplified in fanfictions. They could create new and even more spectacular magical pranks specifically aimed at Umbridge, like turning her office into a never - ending maze of trick stairs and hidden rooms filled with various magical creatures that drive her crazy.
In the original 'Harry Potter' series, the relationship between Harry and Snape was one of mutual dislike but also a certain level of respect in the end. However, in this fanfiction, it's a complete break. The fanfiction might change the power dynamics at Hogwarts as well. Snape was a key figure in the school's hierarchy, and his death at Harry's hands would send shockwaves through the staff and students, unlike anything in the original story where his death was a heroic sacrifice.
The 'Snape kills Harry' fanfiction would shatter the relationships that were built in the original series. For example, the friendship between Harry, Ron, and Hermione would be left in tatters. Hermione and Ron would be devastated and likely seek revenge. Also, Dumbledore's plan, whatever it was that involved Harry, would be completely ruined. The whole balance of good and evil in the wizarding world would be thrown into chaos.
Well, it completely flips the dynamic. In the original series, Snape was a complex character with a lot of hidden motives that were ultimately revealed to be on the side of good. If Harry kills Snape in the fanfic, it makes Harry seem more impulsive and less of the heroic figure we know. It also undermines the redemption arc that Snape had in the original story.
Another idea is a time - travel fanfiction. Harry goes back in time and has to deal with Umbridge when she was a student. He tries to change her path so that she doesn't become the horrible person she is in his time. This could involve him befriending her and showing her the value of kindness and freedom.
