One interesting storyline could be a character who is an underdog in the dueling tournament but discovers a hidden power or spell that helps them succeed. For example, a Hufflepuff student who has been overlooked in the past suddenly masters an ancient dueling technique.
Then there's Max, a Muggle - born wizard who has to face a lot of prejudice in the tournament. His journey of proving himself against all odds makes him a beloved character in many fanfictions. He shows that determination and hard work can overcome the barriers of blood - status in the wizarding world.
Obviously, Harry Potter himself. There could also be Japanese wizard characters who are his opponents in the dueling tournament. Maybe Hermione and Ron could come along with Harry, or they could be back at Hogwarts while Harry is in Japan, but still communicate with him. There might also be some Japanese magical teachers or judges in the tournament.
It could involve Harry Potter participating in a dueling tournament set in Japan. Maybe he meets new wizards, discovers unique Japanese magical spells and creatures during the tournament. There could also be cultural clashes and fusions, like how the Western style of dueling he's used to interacts with the Japanese magical traditions.
Another possibility is a new character created specifically for the fanfic. This character could have some unique magical abilities or a special connection to dark magic that makes them a formidable opponent for Harry. They might have been training in secret for a long time just to face Harry in the tournament.
Harry Potter himself is often a central character in these fanfictions. Since he is already known for his skills in the original series, he can be portrayed as an even greater dueling prodigy. Hermione Granger is also popular as she is intelligent and could use her knowledge to develop unique dueling strategies. Draco Malfoy is another one, as his rivalry with Harry can be further explored in the context of dueling.
Well, there are dueling scenarios where characters from different generations meet in a magical duel. For example, a character from Harry's time might accidentally travel back and duel with a student from the Marauders' era. This can lead to some really creative uses of magic as they try to outwit each other with different spells and strategies they've learned in their respective times.
Harry Potter himself is often a very popular character in dueling fanfiction. After all, he is the main character in the original series and has many dueling experiences. Hermione Granger is also popular as she is known for her intelligence and quick thinking, which would make her a formidable dueler. Draco Malfoy is another common character. His family's reputation for dark magic and his own rivalry with Harry make him an interesting character to feature in dueling scenarios.
A great plotline is when a new student at Hogwarts, who has a mysterious background, enters a dueling tournament. They start out underestimated but as the duels progress, they show extraordinary skills that seem to be related to an ancient magic. Also, in some fanfiction, there are duels that involve magical creatures. For example, a wizard might have to duel while also protecting a unicorn from dark wizards. This adds an extra layer of complexity and danger to the duel. Additionally, a plotline could be about a character who has lost their magic in a duel and has to find a way to regain it through a series of challenges and duels.
