Maybe Firenze the centaur. Centaurs are known for their combat skills and Firenze, being friendly towards Harry, could teach him the art of sword - fighting. He might have a different perspective on combat compared to human wizards.
Maybe Naruto is given the dual swords by a mysterious figure. As he starts using them, he realizes that they have a connection to an old prophecy. So he has to master the swords while also dealing with the various factions in the ninja world who either want to help him or stop him because of the prophecy.
Basilisk blood could potentially be used for healing in fanfic, but with great risk. It's so potent that it might be able to cure otherwise incurable diseases or wounds in a wizarding world, but its dark and dangerous nature could also have unforeseen side effects, like corrupting the user's magic or mind. For example, a character desperate to save a loved one might use it, only to find themselves slowly losing control of their powers.
A 'Harry Potter uses Dresspheres' fanfic would likely blend the magic systems of both worlds. Dresspheres could be reimagined as magical artifacts in the Harry Potter universe. Maybe Hermione would study how to adapt Dressphere technology to Hogwarts' magic. Harry could use them in battles against Voldemort, having an edge with the unique abilities they grant, like the ability to fly faster or cast more powerful shielding spells.
In a 'Harry Potter uses energy weapons' fanfic, it would likely be a very different take on the original story. The energy weapons could change the power dynamics in the wizarding world. Maybe they would be seen as a threat by some pure - blood wizards who only believe in magic. Harry, being the open - minded hero, would figure out how to use them to his advantage, perhaps even teaching his friends how to use them too. This could lead to new alliances and new enemies within the wizarding community. And the battles would be really cool, with magic spells and energy blasts flying everywhere.
One interesting scenario could be Harry using the staff to perform unique spells that are different from his usual wand magic. For example, he might be able to create large-scale protective shields with a single wave of the staff.
There might be. Fanfiction writers sometimes like to take characters out of their comfort zones and explore darker or more extreme scenarios. But in the official 'Harry Potter' lore, Harry would never casually use the Killing Curse. It's a very serious and immoral spell in the wizarding world.
One interesting plotline could be that Harry discovers an ancient sword with magical properties hidden in Hogwarts. He has to learn how to use it to fight against a new dark wizard threat. Maybe the sword has the power to nullify certain dark spells.
For novels where the protagonist uses many swords, you can refer to the following examples:
Sword Comes
This novel was a famous fantasy novel. It told the story of a fantasy world where the main character, Xiao Yan, started off with a Shadowless Sword and experienced all kinds of difficulties as he trained and grew until he finally became a Sword God. In the novel, there were many different swordsmen, each with their own unique abilities and stories. Together with Xiao Yan, they formed a powerful sword formation and worked hard to complete Xiao Yan's mission and defeat his enemies.
Battle Through the Heavens
This novel also described a fantasy world where the main character, Xiao Yan, mainly focused on training and fighting. During his training, he encountered many challenges and difficulties, and at the same time, he made many like-minded companions. In the novel, there were many different Dou Qi continents and Dou Shi characters. Each character had their own unique abilities and story to help Xiao Yan grow and eventually become a Dou Di.
Fanfic can be a way for fans to explore different scenarios and ideas related to Harry. It might allow for new character developments or alternative storylines that the official works haven't covered. For example, some fanfics could focus on Harry's life after the main events in the books, showing how he deals with being a hero in a more normal, day - to - day context.
