What could be the plot of a 'Harry Potter Master Swordsman' fanfic?

Yes, there are likely fanfics out there with this concept. You can try searching on popular fanfic websites like Archive of Our Own or FanFiction.net.

A swordsman could change the plot by adding a new element of combat. For instance, if there was a powerful swordsman on the side of the Order of the Phoenix, they could engage in more direct physical battles against Voldemort's forces. Instead of relying solely on magic, they could cut through enemy lines with a sword, which would be a different approach compared to the usual magical duels.

The plot could start with Harry finding a mysterious sword in the Forbidden Forest. As he touches it, he gains knowledge of an ancient form of swordsmanship. He then starts training in secret. As he gets better, he realizes that this new skill is connected to a prophecy. He has to face Voldemort not with magic alone but with his sword - fighting abilities as well. Along the way, he might face challenges from those in the wizarding world who don't believe in this new approach, thinking it's too dangerous or against the traditional ways of magic. But Harry perseveres, believing that this is the key to finally defeating Voldemort.

Well, one plot element is the discovery of the sword - related power or ability. Maybe it's a magical sword he finds or a latent ability within him that he unlocks. Then there's the part where he has to keep it a secret at first, because it's so different from normal wizarding abilities. And of course, there are often battles where his swordsmanship gives him an edge over his opponents, making him a key player in the fight against the dark forces in the wizarding world.

Well, the squib swordsman in a Harry Potter fanfic might be an outcast among the wizards at first. But as the story progresses, they could find a niche. Since they can't use magic like others, they train hard with swords. Their story could involve them facing dark wizards who underestimate them because they are squibs. But then the swordsman shows them that they are a force to be reckoned with, using their sword skills and knowledge of the wizarding world's secrets that they've learned from the sidelines.

In Harry Potter fanfic, Harry himself could be a great swordsman. He has shown courage and quick reflexes in many dangerous situations. The Sword of Gryffindor already has a connection to him, and it would be interesting to see him master sword - fighting skills with it. He could use it not just against the basilisk but also in other battles against dark forces.

One possible plot could be that Harry Potter somehow gets transported to the Halo universe. He has to learn to use Master Chief's weapons and fight alongside him against the Covenant. Meanwhile, he also tries to figure out how to use his magic in this new high - tech world.

Well, it could be about Harry using his skills and influence in the wizarding world to reform the political system. Maybe he starts by uniting different magical communities within Hogwarts, like the houses, and then expands it to the whole wizarding society.

The plot might center around Harry being the master of darkness as a way to subvert the prophecy. Instead of being the 'Chosen One' in the typical light - against - dark way, he uses the knowledge of the dark arts to understand and outwit Voldemort. He could be learning long - forgotten spells from the darkest corners of Hogwarts library and using them to his advantage.

It could be about Harry Potter achieving a new level of power and using it to bring great changes in the wizarding world. Maybe he masters a form of magic that gives him control over life itself, like being able to heal any injury or even bring the dead back to life in a limited way.
