One fanfic that stands out for its plot is 'Hotaru's Quest for the Lost Spell'. Hotaru discovers a reference to a powerful lost spell in an old Hogwarts library book. She embarks on a quest to find the spell, but she's not the only one after it. There are other dark characters also in pursuit. The story unfolds with her facing many challenges, from dangerous magical creatures to tricky magical puzzles, all while trying to keep the spell out of the wrong hands.
There's a fanfic that I think fits the bill. In it, Hotaru is suspected of being a spy for a rival magical school. The plot thickens as she tries to prove her innocence while also uncovering a plot by a group of dark forces to take over Hogwarts. This fanfic is full of twists and turns, with Hotaru having to use her wits and new - found friendships to survive and clear her name. It's a great read if you like complex plots.
I'm not sure of a specific one off - hand, but you can often find great ones on fanfic platforms. Look for those with high ratings and lots of reviews. Usually, a fanfic with a strong plot will have a clear goal for the characters. In the case of 'Harry Potter Black Flash' fanfics, it could be about a character using the Black Flash to solve a mystery or overcome a great threat in the wizarding world.
Definitely 'The Enchanted Bond between Hermione and Fleur'. In this fanfic, there's a strong plot centered around a magical mystery that Hermione and Fleur have to solve together. Their relationship blossoms as they work side by side, facing dangerous spells and dark secrets. It's not just about the romance but also about their growth as witches.
There could be a fanfiction where a selkie has been cursed and the only way to break the curse is through a complex spell that requires knowledge from both the selkie world and the wizarding world of Harry Potter. The plot could involve the characters traveling between different magical realms, gathering ingredients, and facing various challenges along the way. This would create a really engaging and complex plot that ties the two worlds together.
One more is 'Among the Durmstrang'. In this fanfiction, the plot focuses on a group of Durmstrang students who come to Hogwarts for a tournament. But there is an underlying plot of a conspiracy within Durmstrang that the main characters gradually uncover. It's a very engaging read with a well - developed plot.
There's a fanfiction called 'Naga and the Dark Prophecy'. The plot is quite strong as it involves a Naga who discovers a dark prophecy that concerns the future of the wizarding world. The Naga then teams up with Harry Potter to try and prevent the prophecy from coming true. The story is filled with twists and turns as they battle against powerful dark wizards who are also interested in the prophecy. It also explores the Naga's own motives and backstory in relation to the prophecy.
A fanfiction titled 'Belgher's Quest with Harry Potter' has a strong plot. In it, Belgher discovers a prophecy that involves both of them and a powerful dark magic artifact. They must journey across different magical locations, from the Forbidden Forest to the hidden chambers of Hogwarts, to stop the artifact from falling into the wrong hands. Along the way, they face numerous challenges and encounter old enemies and new allies.
Yes, there's a fanfiction where the Revelio Zauber is the key to solving a mystery about a series of disappearances in the wizarding world. The main character uses the spell to gradually uncover clues that lead to a powerful dark force that has been operating in secret. It has a really strong plot full of twists and turns.
Another one is 'Magic and Monsters'. Here, the plot is centered around a new kind of monster that is attracted to the magic in Hogwarts. The Supernatural characters come to investigate, and they end up getting caught in a web of Hogwarts politics and magical intrigue. The author does a great job of building the story, slowly revealing the mystery behind the monster and how it relates to both universes, all while the characters are growing and changing in this new and strange environment.
I would recommend 'Blood and Magic: The Blood Bender's Tale'. It has a really strong plot that revolves around a Blood Bender who is actually a descendant of an ancient magical bloodline. The story unfolds as they try to uncover the secrets of their bloodline while also dealing with the normal Hogwarts drama and the threat of dark forces. There are many twists and turns, like when they find out that their blood power is linked to an ancient prophecy that could change the fate of the wizarding world.
There might be a fanfiction where the panther animagus is an outcast in the wizarding world because of their form. They then get drawn into Harry Potter's fight against the dark forces. As the story progresses, the panther animagus discovers their true potential and their role in the grand scheme of things. This would be a strong plot as it involves character development, a sense of belonging, and the overarching battle between good and evil in the Harry Potter world.
