What are some interesting ideas for 'harry potter and the goblet of fire oc fanfiction'?

One idea could be that the OC is a foreign exchange student who has unique magical abilities unknown to Hogwarts. They could help Harry in the Triwizard Tournament tasks in unexpected ways, like using ancient spells from their home country.

A cool plot could involve a crossover with 'Star Wars'. Picture Harry using the Force in addition to his magic while competing in the Triwizard Tournament. Or perhaps a crossover with 'Alice in Wonderland' where the Goblet of Fire sends Harry down the rabbit hole and he has to navigate Wonderland's strange rules during the tournament.

One idea could be that Harry has a group of friends from different houses who are all secretly in love with him. They start to form a sort of harem around him during the Triwizard Tournament. For example, Hermione could be using her intelligence to help him in the tournament in a more personal way, and Cho Chang might be more openly affectionate, and then there could be a girl from Beauxbatons who is also drawn to Harry's bravery.

One idea could be exploring what would happen if a different student was chosen by the Goblet of Fire. Maybe a Muggle - born student who has to face extra prejudice during the Triwizard Tournament. It would add a new layer of conflict and show how the wizarding world reacts to a 'less likely' champion.

One interesting plot idea could be exploring what would happen if a different student was chosen for the Triwizard Tournament. Maybe a shy and overlooked student gets picked, and they have to overcome not only the tournament tasks but also their own insecurities. Another idea could be a love triangle involving characters that were not part of one in the original story. For example, a friendship between a Hufflepuff and a Slytherin turns into a complex relationship when feelings for Harry Potter get involved.

One idea could be introducing a new character from another universe who accidentally gets transported into the Goblet of Fire timeline. This character could have unique magical abilities that both fascinate and worry the Hogwarts students. For example, they might be able to control time in a different way than Hermione's time - turner. Another plot idea could be that Voldemort discovers a new dark magic spell from this other universe through a mysterious object. This could make him even more powerful and the trio has to find a way to stop him using knowledge from both universes. Also, what if the Goblet of Fire chooses a student from a completely different magical school in this crossover? It would create a whole new dynamic of competition and friendship.

Another idea is that Snape could be the one who discovers a plot by a Death Eater to use the Triwizard Tournament to bring Voldemort back in a more powerful form. Snape then has to decide whether to take matters into his own hands or trust Dumbledore with this information. This would create a lot of tension and drama as Snape is not one to easily trust or be trusted.

One idea could be exploring an alternative version of the Triwizard Tournament. For example, what if the tasks were designed by a dark wizard who had infiltrated the Ministry of Magic? This would add a whole new level of danger and mystery to the story. Another idea could be focusing on a character other than Harry in the tournament. Maybe Neville Longbottom gets chosen by the Goblet of Fire and has to face his own fears and insecurities throughout the tasks. It could show his growth and transformation into a more confident wizard.

One possible interesting plot could be Harry's internal struggle with being forced into the Triwizard Tournament. He might have to deal with the pressure of competing while also trying to figure out who or what is behind this forced entry. Another plot could involve how his relationships with Ron and Hermione change due to this unexpected situation. Maybe Ron becomes jealous at first because Harry gets all the attention, but then they reconcile as they realize it's not Harry's fault.

One interesting plotline could be Draco secretly helping Harry during the Triwizard Tournament. Maybe he has a change of heart and realizes that the dark side isn't what he really wants. Another could be a friendship forming between them in the face of a common enemy within the tournament. For example, a dark wizard who tries to manipulate the tasks for their own evil purposes.
