One great fanfiction could be 'The Unseen Bond'. It explores an unexpected connection between Harry and Grayback. It delves into how their fates cross in a world where the line between good and evil is more blurred than in the original series. The author creates a complex relationship, showing how Harry's presence affects Grayback's actions and vice versa.
There's 'Harry and Grayback: A Forced Alliance'. In this fanfic, due to some dark magic machinations, Harry and Grayback are forced to work together. It's interesting as it shows Harry having to deal with his natural aversion to Grayback while also trying to achieve a common goal. The story is full of action and moral dilemmas.
A lesser - known but very well - written fanfiction is 'Grayback's Redemption through Harry'. Here, Harry becomes the catalyst for Grayback's possible redemption. It's a story that goes against the typical view of Grayback as just a villain. It shows that with Harry's influence, there could be a change in Grayback, exploring themes of forgiveness and second chances.
One popular 'Harry is related to Sasuke' fanfiction might be 'The Unlikely Connection'. It explores how, in a crossover universe, Harry and Sasuke could be related through some sort of magical - ninja bloodline mix - up. It has interesting plot twists where they discover their relation while facing a common enemy.
I'm not entirely sure specifically as it's a fanfiction. But generally, 'mpreg' stands for male pregnancy in fanfiction worlds. It might involve a story where Harry from the Harry Potter series is in a situation related to male pregnancy in a plot created by the author named Grayback. However, without reading it, it's hard to give more details.
One good Petunia - related fanfiction could be 'Petunia's Secret'. It delves into Petunia's hidden emotions and her complex relationship with the wizarding world. In this fanfic, it might show how she really felt about Lily's magical abilities all along and her internal struggle with envy and love for her sister.
I'm not sure about its popularity. There are so many fanfictions out there that it's hard to gauge the popularity of just one. It might be popular among a niche group who are interested in the concept of mpreg and Harry Potter, but it may not be widely known to the general Harry Potter fanbase.
One popular 'Harry Potter' fanfiction that might touch on abuse and boggarts could be 'The Hidden Horrors'. In this fic, the boggart reveals deeper, often abuse - related fears of the characters that are not fully explored in the original series. Another could be 'Boggarts Unleashed' which delves into how boggarts can be manifestations of past abuse experiences of the Hogwarts students.
One possible Harry Potter fanfiction related to 19th September could be one where a significant event in the wizarding world takes place on that day. For example, it could be a story about a new spell being discovered at Hogwarts on 19th September. Maybe a young wizard or witch has a special encounter with a magical creature on this day that changes their understanding of magic.
Well, there's a fanfiction called 'Envy and the Forbidden Artifact'. In this story, envy drives a character to seek a powerful and forbidden artifact at Hogwarts. This could put Harry and his friends in danger as they try to stop this character. Another fanfiction could be 'The Envious Eye on Harry's Inheritance'. Maybe there are those who envy Harry's potential inheritance from his parents or his connection to powerful magic. 'The Envy - Filled Rivalry in Quidditch' is also possible, where a rival team's player is envious of Harry's skills in Quidditch and tries to sabotage him during the games.
One possible fanfiction could be about Snape using some sort of magical force with his fingers to protect Harry in a dangerous situation. For example, in a battle against dark wizards, Snape might use a unique spell cast with his fingers to create a force field around Harry.
Well, there could be fanfictions where Harry discovers new, unknown magical animals. Maybe he stumbles upon a hidden grove where there are tiny, glowing creatures that can heal wounds. Or perhaps he has an encounter with a shape - shifting animal that he has to figure out how to deal with.
Fanfiction often varies greatly in quality and content. However, creating or promoting fanfiction with sexual or inappropriate themes goes against the family - friendly nature of the 'Harry Potter' franchise. It's better to focus on positive, plot - driven fanfictions that explore friendship, magic, and the wizarding world.
