Well, in some fanfictions like 'Martial Arts Harry Potter', the concept is taken further. Harry is sent to a different realm where he masters martial arts and then brings those skills back to the wizarding world. This changes the power dynamics and how he interacts with his friends and enemies. It's a fresh take on the Harry Potter universe.
Yes, there are likely some fanfictions out there where Harry Potter uses martial arts. Fans often like to create unique crossovers and scenarios in fanfiction, and combining the magical world of Harry Potter with martial arts is an interesting concept that some writers might explore.
One popular 'Harry Potter Martial Arts Master' fanfiction is 'The Potter Who Knew Kung Fu'. It combines the magic of the Harry Potter world with martial arts in an interesting way. The main character, Harry, discovers ancient martial arts secrets and uses them alongside his magic to fight against the dark forces.
One interesting fanfiction could be 'Harry Potter: The Martial Arts Wizard'. In this story, Harry discovers his talent for martial arts early on. It combines the magic of the Harry Potter world with exciting martial arts battles. Another one might be 'Martial Potter', where Harry uses martial arts to defeat his enemies in a unique way, adding a new dimension to the fight against Voldemort.
There is a fanfiction that delves into the idea of druids in the Harry Potter universe. It starts with a character who has a hidden druidic heritage. As the story progresses, we see how the druidic magic, which is more nature - based compared to the traditional Hogwarts magic, clashes and also complements the existing magical system. The author does a great job of building a new world within the framework of the Harry Potter series, with druids having their own unique place and abilities.
One great 'bookworm Harry Potter fanfiction' is 'The Library of Hogwarts'. It delves into the idea of a secret library within Hogwarts that contains all sorts of forgotten spells and knowledge. It's really interesting as it combines the love for books with the magical world of Harry Potter.
One great 'Harry Potter Morrigan fanfiction' is 'The Meeting of Magic'. It's really interesting as it combines the magic of the Harry Potter world with the mysterious Morrigan. The author does a wonderful job of creating a new adventure for Harry where he encounters Morrigan and they have to work together to solve a dark mystery in Hogwarts.
One popular Harry Potter handsome fanfiction is 'The Boy Who Lived Again'. It gives a different take on Harry's character, making him even more charming and heroic. The author describes his looks in a very alluring way and also adds some interesting plot twists to the original story.
There is likely some 'Harry Potter loves the Dark Arts' fanfiction. Some might depict Harry being curious about the Dark Arts due to his difficult life. For example, he could be frustrated with the limitations of the 'good' magic he's been taught and start to explore the more dangerous and forbidden Dark Arts. But these are often non - canon interpretations.
Personally, I'm a bit hesitant about it. While the concept of a 'dark arts prodigy' Harry Potter in fanfiction can be exciting, it could also change the essence of the character. Harry in the original series is a hero who stands against the dark arts. But if the fanfiction is well - written and manages to balance this new concept with the core values of the Potterverse, it could be a great read.
One interesting fanfic could be 'Harry's Martial Arts Adventure'. In this, Harry discovers an ancient martial arts manual in the Hogwarts library and starts training secretly. It shows how he combines magic with martial arts moves, making for some really cool battle scenes against dark wizards.
