I would recommend 'Harry's Solitary Stand'. In this fanfiction, Harry finds himself isolated from his friends due to a misunderstanding. Instead of waiting for them to come around, he stands up for himself and his actions. He embarks on a solo adventure where he discovers new aspects of his magic and his own strength. It's a really interesting read as it shows Harry's growth outside of his usual support network.
One scenario could be in the Hogwarts corridors. Maybe some Slytherins are taunting Harry about being a half - blood. In the fanfiction, Harry decides he's had enough. He stands up straight, looks them in the eye, and firmly tells them that his blood status doesn't define him. He uses his skills in magic, like a well - executed non - verbal spell, to show he's not to be trifled with.
One great 'Harry Potter stands up for himself' fanfiction is 'The Power Within'. In this story, Harry decides he's had enough of being pushed around by the Ministry and starts to take matters into his own hands. He uses his knowledge of magic in unexpected ways to fight against the unjust rules. Another is 'Harry's Rebellion' where he rebels against Snape's unfair treatment in Potions class and shows his true skills and confidence.
Ron and Hermione are the most likely. They've always been by Harry's side in the original series. In the fanfiction, when Harry stands up for himself, they would surely be there. Ron might use his sense of humor to diffuse the situation if it gets too tense, while Hermione would back Harry up with her vast knowledge of wizarding laws and rights.
There's a fanfiction called 'James Potter: Beyond the Veil'. In this story, after James' death, his spirit gets trapped in a strange realm beyond the veil. Harry, through some unforeseen circumstances, is able to communicate with his father's spirit. Together, they have to find a way to break free from this realm and also prevent a dark force from using this connection between them to gain access to the living world. It's a very different take on the relationship between James and Harry.
One possible fanfiction could be where Jon Snow stands up to the Night King directly. He might use his skills and knowledge of the enemy to taunt the Night King, saying that he will never succeed in his dark plans. This shows his courage and determination to protect the realm.
One that stands out is 'The Paranoid Potter'. In this fanfiction, Harry has a premonition that Voldemort is not truly gone. He becomes extremely paranoid and starts to investigate every little strange occurrence. It has great character development as Harry's paranoia affects his relationships with his friends and teachers.
I've read one where Cibola was like a hidden magical library that only a select few in the Harry Potter universe knew about. Harry stumbles upon it and finds out that it holds the key to a powerful magic that could defeat Voldemort once and for all. It was really unique as it combined the mystery of Cibola with the main plot of the Harry Potter series.
Sure. There's one where Stonehenge is actually a magical prison for an ancient and extremely dangerous dark wizard. Harry and his friends accidentally release the wizard and then have to find a way to re - imprison him using the magic of Stonehenge itself. It's full of action and mystery.
There's a great fanfiction called 'Professor Snape's Unseen Allies'. It has a unique plot where Snape is not as alone as he seemed in the original story. He has a group of underground allies within Hogwarts, including some of the other professors, who are helping him in his mission to protect Harry. It gives a whole new perspective on Snape's actions and his relationships with the other faculty members. This fanfiction is full of twists and turns that keep you hooked from start to finish.
One unique 'Harry Potter Artemis' fanfiction involves a plot where an ancient magical artifact is causing chaos in both the wizarding world and Artemis' world. Harry and Artemis have to work together, along with their respective friends, to find and destroy the artifact. The story is full of action and adventure as they travel between the two worlds, facing different challenges in each one. It also explores how the two groups of characters with very different skills and backgrounds come together to achieve a common goal.
