In a fanfic, Harry could stand up for himself against the Ministry of Magic. Let's say the Ministry tries to control Hogwarts and limit the students' freedom. Harry, having had enough of their interference, could lead a student protest. He would use his influence among the students, his past experiences of fighting against Voldemort, and his knowledge of the wizarding world's laws to make a strong case. This would be a great instance of him standing up for himself and his fellow students, rather than just following the Ministry's orders blindly.
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.
There may be some dark or angsty fanfics with such a concept, but self - harm themes are quite disturbing. In the 'Harry Potter' universe, this would be a very uncanonical and concerning take. It might explore a very different, perhaps depressed version of Harry Potter going through extreme emotional distress and using self - harm as a way to cope, but this goes against the overall spirit of the original series.
I'm not aware of any such official 'Harry Potter' fanfic with that rather inappropriate and unappealing concept. J.K. Rowling's original 'Harry Potter' series is full of magic, adventure, friendship and heroism, and most fanfics tend to follow positive themes related to the world she created.
One great realistic Harry Potter fanfic could be one that focuses on the daily life of Hogwarts students outside of the main adventures. For example, a story about how they study for regular exams, deal with relationships among different houses, and the small rivalries and friendships that form in the common rooms. It might show the less glamorous side of Hogwarts life, like having to clean up after a potions class gone wrong or dealing with a strict teacher during a regular school day.
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 fanfiction could be where Harry discovers some false accusations Snape made against his friends. He stands up by gathering evidence and presenting it to Dumbledore. This changes the way everyone in Hogwarts views Snape for a while.
There could be a fanfic where Artemis is sick and Harry Potter uses his magic to try to heal him. Maybe he brings some potions from Hogwarts. For example, the Pepperup Potion which is known for curing common ailments. Harry might face challenges in using magic outside of Hogwarts to help Artemis, as it's against wizarding laws in some cases.
In some fanfictions, Harry might use his magic skills in a creative way to outwit bullies. For example, he could use a charm to make the bully's wand malfunction when they try to attack him. This shows his intelligence and ability to stand up for himself and others without using excessive force.
There could be a fanfic that focuses on the Marauders in their school days in a non - sexual ageplay way. It could explore their pranks and the bond they formed. For example, showing how they created the Marauder's Map and the troubles they got into while testing it out, all while staying true to the spirit of the original 'Harry Potter' series and being appropriate for all ages.
One example could be fanfics that focus on a character with a learning disability at Hogwarts. Maybe they struggle with certain spells but find unique ways to overcome. Another could be about a character with a physical special need who uses magic to adapt and thrive in the wizarding world. For instance, a fanfic about a wheelchair - using wizard who modifies their chair with magic for various tasks.
