Perhaps Luna enters the Triwizard Tournament instead of one of the original champions. During the tournament, she suffers from amnesia due to a dark spell cast by an enemy. Harry, who has a soft spot for Luna, steps in to protect her and tries to help her regain her memories. He might use the Pensieve to show her past memories, if he can figure out how to use it in this context.
Well, it could start with Harry getting cursed during the Triwizard Tournament, which results in amnesia. Luna, with her off - beat wisdom, could sense something is wrong. She starts to investigate and tries to reverse the curse using her knowledge of unusual magic. For instance, she might recall a rare spell from an old book she once read.
One possible fanfiction could be about Harry getting amnesia during the Triwizard Tournament and Luna being the one to help him remember. Maybe she uses her unique perspective and knowledge of magical creatures and odd things to jog his memory. For example, she might take him to see the Thestrals, which are associated with death and memory in the wizarding world.
One great fanfiction could be where Harry and Luna team up in a unique way during the Triwizard Tournament tasks. Maybe Luna uses her off - beat magical knowledge to help Harry solve the puzzles in the maze. For example, she might recognize some magical creatures that Harry is unfamiliar with and guide him through.
A possible plotline is that Luna enters the Triwizard Tournament as an unexpected champion. Harry, already in the tournament, teams up with her to face the challenges. They use their combined skills, Harry's Gryffindor courage and Luna's Ravenclaw wisdom, to overcome the tasks.
One possible scenario in this fanfiction could be that Harry and Fleur form an unexpected alliance during the Triwizard Tournament tasks. They might discover they have complementary skills, like Harry's courage and Fleur's elegance and magic related to water (since she's from Beauxbatons). This alliance could lead to them facing the challenges in a new and interesting way, perhaps with Fleur using her Veela charm in a creative manner to distract the obstacles while Harry uses his Gryffindor bravery to take on the more physical parts of the tasks.
One possible fanfiction could be about Harry and Hermione teaming up secretly during the Triwizard Tournament tasks. They might use their combined knowledge and skills to outwit the other competitors. For example, in the maze task, they could have a special code to communicate and find their way to the Triwizard Cup faster than anyone else.
In some fanfictions, Draco might provide crucial information or clues to Harry that help him navigate the challenges of the tournament.
One possibility could be that Harry discovers some dark magic or a hidden conspiracy within the Triwizard Tournament that forces him to take extreme measures and destroy it. Maybe he finds out that the tournament is being used as a cover for an evil plot against Hogwarts or the wizarding world in general.
A wizard from a far - off land, like a wizard from a hidden tribe in the Amazon rainforest. He or she could bring a completely different style of magic that the Hogwarts students and other champions have never seen. Their magic could be more nature - based, using the power of the rainforest plants and animals. This would make their approach to the Triwizard tasks very different and exciting.
It could also be due to personal reasons related to his growth and self - discovery. The events of the Triwizard Tournament might make him realize that he needs to find his own path outside of Hogwarts for a while. He might feel that the school can't offer him the answers or the experiences he needs at that moment to become stronger and more independent.
Maybe in fanfiction, Harry hates the Triwizard Tournament because it brings too much danger and unwanted attention. He has to face powerful opponents and deal with complex rules that he may not be fully prepared for.
