One idea could be exploring the Triwizard Tournament from the perspective of a new, original character. This character could be a transfer student who has a secret ability that helps Harry in some way during the tournament. Another plot could involve a mystery related to the Dark Arts that is intertwined with the events of the tournament, like a cursed object that is affecting the champions. Maybe a long - lost relative of one of the main characters shows up during year 4, causing chaos and confusion as they try to interfere with the events at Hogwarts.
A possible plot for a year 4 Harry Potter fan fiction could be centered around the Yule Ball. Imagine a story where a character creates a magical charm that goes wrong at the ball, causing everyone's dance partners to switch uncontrollably. This could lead to some really funny and awkward situations. Additionally, you could have a sub - plot where a student discovers a hidden passage in Hogwarts that has a connection to the Triwizard Tournament tasks, and they have to decide whether to share this information or keep it a secret.
Well, you could have a fan fiction where the Goblet of Fire's selection process goes horribly wrong. Instead of choosing the correct champions, it starts choosing random students from different houses. This forces the teachers and Dumbledore to figure out how to deal with this mess while also trying to keep the real champions safe. Also, a plot where there is a secret society within Hogwarts that is trying to manipulate the Triwizard Tournament for their own gain, and Harry and his friends have to expose them.
How about a muggle - born witch who has been hiding her magic for a long time because she was scared of the wizarding world. But during year 4, she finally decides to embrace her magic and attends Hogwarts. She has a lot of fresh perspectives on things like the Triwizard Tournament, as she has only recently learned about the wizarding world's traditions.
One idea could be that Harry discovers a new, hidden magical ability within himself that helps him in the final battle against Voldemort. For example, the ability to communicate with the spirits of Hogwarts founders for guidance. Another could be that the relationships between the characters take a different turn. Maybe Hermione and Ron have a huge fight early on and Hermione teams up with Draco for a while out of necessity, which changes the dynamics of the whole group. Also, Neville could have an even more prominent role, leading a secret group of students who are training in a new form of magic that they hope will give them an edge in the fight.
Maybe in this fanfiction AU, the relationship between Harry and Hermione develops romantically during the fourth year. This would change the dynamics of their friendship and how they interact with Ron. They could face challenges together in the tournament, relying on their newfound feelings to get through difficult situations.
One idea could be exploring the backstories of minor characters. For example, the life of Neville's parents before they were tortured by Bellatrix. Another could be a story set in a different wizarding school around the world and how it interacts with Hogwarts. Maybe a story about a group of students from Beauxbatons and their adventures during the Triwizard Tournament that we didn't see in the original books.
One interesting storyline could be a different take on the Triwizard Tournament. Maybe a new champion from an unexpected house participates. Another could be exploring Harry's relationship with Sirius Black during that year in a more in - depth way than in the original. And also, fan fictions might show how the other students reacted to the events of the tournament, like Hermione's attempts to figure out the mystery behind the tasks before Harry.
Well, a cool plot twist might be that in this 4th - year AU fanfic, the Triwizard Tournament tasks are all designed by a rogue Death Eater who has infiltrated Hogwarts' staff. So the tasks are not just tests of courage and skill but also traps to try and harm the students. Also, Harry might discover that his parents were actually part of a secret society within the wizarding world that was fighting against a different dark force, not just Voldemort, which changes his whole perspective on his family and his role in the wizarding world.
In 'harry potter super fan fiction', a very cool idea is the exploration of different magical cultures. We might see how the wizarding cultures in different countries interact more. Say, a fan fic could focus on a group of students from Hogwarts going on an exchange to a wizarding school in Japan and the cultural clashes and new magic they discover there. Also, some fan fictions delve into the idea of magic in the muggle world, like a secret society of muggles who have a little bit of magic in them but don't know how to use it properly.
One idea could be that a character from the Harry Potter world leaps into the body of a Quantum Leap character and has to navigate their life while also trying to find a way back. For example, Harry could leap into Sam Beckett's body during one of his more dangerous leaps and use his magic skills to help Sam complete the mission.
One interesting plot idea could be exploring the alternate timelines more deeply. For example, what if the characters got stuck in a timeline where Voldemort had won? Another could be delving into the relationships between the next generation of characters in ways not fully explored in the original play. Maybe a story where Albus and Scorpius have to face a new dark wizard threat together, relying on their unique bond.
Perhaps a fan fic where a student travels back to the time of the founders of Hogwarts. They could witness the creation of the houses and the laying of the school's foundation, and even interact with the founders, which would be really cool.
