What could be a good plot for a 'Harry Trains for Goblet of Fire' fanfic?

It could be Sirius Black. He has a lot of experience in the wizarding world and, despite being on the run, he could find a way to communicate with Harry secretly. He could teach Harry about dark magic defense, which would be very useful in the tournament.

The fanfic might revolve around Harry's interaction with the Goblet of Fire due to a misunderstanding. He could think that the goblet is being influenced by dark magic and decides to investigate. As he messes with it, he discovers some hidden secrets about the Triwizard Tournament and its origins. This could lead to him having to make difficult choices to protect the integrity of the tournament and Hogwarts, all while dealing with the consequences of his meddling with such a powerful magical object.

Perhaps Harry is transported to a time in the past during the Goblet of Fire event. He could interact with the founders of Hogwarts, and they could give him advice on how to deal with the dark forces that are at play in his own time. This would add a historical and magical depth to the fanfic.

A possible plot is that Harry gets angry at the unfair treatment he receives during the tasks of the Goblet of Fire. For example, in one task, he might notice that the other champions have some advantages that he doesn't. His anger then gives him the motivation to find a way to overcome these unfair situations and still succeed in the tournament. He could use his anger to fuel his creativity and come up with unique solutions to the challenges.

A possible plot could be that adult Harry is called back to Hogwarts due to some strange magical disturbances related to the Goblet of Fire. He realizes that there are remnants of dark magic from the tournament that were never fully eradicated. He then has to work with the current Hogwarts staff and students to find and neutralize these dark magic sources.

Well, it could be that Hermione accidentally drinks a love potion during the Goblet of Fire events. Harry is the only one who can break the spell. The 'lemon' aspect might be some flirty and slightly spicy interactions as Harry tries to bring Hermione back to normal. For example, a scene where Harry has to hold Hermione's hand a bit longer than necessary while reciting a counter - spell.

A possible plot could be that the Goblet of Fire starts acting strangely. McGonagall notices some odd magical fluctuations around it. She enlists the help of Hermione, knowing her academic prowess. Together they try to figure out what's wrong. Meanwhile, Harry has a strange feeling about it all. Eventually, they discover that a dark wizard from the past is trying to use the Goblet to return. And they must stop it before it's too late.

Harry Potter and the Goblet of Fire was a very popular novel that was widely regarded as one of the classic works of literature. It was written by JK Rowling and tells the story of Harry Potter and his friends 'adventures in order to obtain the highest honor in the wizarding world. The story is full of magic, friendship, courage, loss and hope, immersing the readers in a magical world.

Therefore, Harry Potter and the Goblet of Fire is a novel that is worth reading. It not only brings a pleasant reading experience, but also gives readers some deep thoughts and enlightenment.

Well, perhaps in this fanfic, the Goblet of Fire might summon Harry in a different way than in the original story. Maybe it has a mind of its own and specifically targets Harry for a more dangerous and secretive task that the original Triwizard Tournament didn't include.

One interesting plot twist could be a different champion being secretly controlled by Voldemort instead of just Barty Crouch Jr. as the imposter Moody. Maybe a champion from a different school who no one suspects.
