The plot could start with Harry finding an ancient Jedi artifact during one of his adventures. This leads him to become curious about lightsabers. He then uses his magic knowledge to try and replicate it. Along the way, he might face opposition from some in the wizarding world who think it's too dangerous or against wizarding traditions. But Harry, being the hero he is, persists. Eventually, he creates a lightsaber and uses it to defeat a new, powerful dark wizard who has emerged, using both his wizarding skills and his new lightsaber skills.
Well, in this fanfiction, Harry would probably use his magic to create a unique lightsaber. Maybe he'd combine his wand's magic with the technology of the lightsaber. For example, the blade could be made of enchanted light that can cut through dark magic as well as physical objects. He could use it against Voldemort's Death Eaters in a whole new kind of battle, with the swishing sounds of the lightsaber adding a new level of excitement to the wizarding duels.
Well, in theory, it could. Fanfics often like to blend different fictional universes. However, in the official Harry Potter lore, there are no lightsabers. But in a fanfic, an author could come up with some creative magic or a cross - universe event that brings lightsabers into the wizarding world. Maybe a powerful wizard discovers a way to create a weapon similar to a lightsaber using magic and some rare materials.
There probably is. Fanfiction writers love to blend different fictional universes. In this case, a 'Harry Potter has a lightsaber' fanfic could involve a lot of creative ideas. For example, the lightsaber could be a magical artifact in the Harry Potter world that has been lost for centuries and Harry stumbles upon it. Or it could be a gift from a mysterious figure from another dimension. The possibilities for the story are really endless.
If Naruto creates a lightsaber, it could be related to his connection with Kurama. Kurama's chakra is extremely powerful. It's possible that this chakra could be harnessed in a way that can mimic the energy source of a lightsaber. Naruto, being the creative and adaptable ninja he is, would then figure out how to shape and control this new form of energy into a blade, much like a lightsaber. And he would surely use it to protect his friends and the Hidden Leaf Village.
A 'Harry Potter Lightsaber Fanfiction' could be really interesting. It might involve Harry Potter characters getting their hands on lightsabers. For example, Harry could discover a lightsaber in the Forbidden Forest, and then he has to learn how to use it with the help of Hermione who researches about it in the library. It would be a wild mix of the magic from Harry Potter and the technology of Star Wars.
One idea could be that Harry creates a school for magical creatures. He realizes that there are so many unique and often misunderstood creatures in the wizarding world, and he wants to give them a place to learn and grow. This school could teach them how to interact with wizards in a positive way, as well as develop their own magical abilities.
I think Hermione would be the most likely. She's very intelligent and a quick learner. She would study all the available information about lightsabers, probably find some ancient texts in the library about similar weapons. With her determination and knowledge - seeking nature, she'd be able to master the basic techniques of lightsaber handling in no time.
Maybe an old wizard who has been secretly studying the combination of different magical universes for years. This wizard could have made some initial attempts at building a lightsaber - like weapon in the past and can share his experiences and mistakes with Harry. He would teach Harry about the balance between the light and dark side of this new form of magic, just like the Jedi teachings in Star Wars.
Well, perhaps Harry discovers an ancient magic that allows him to wield a lightsaber. He could use it to fight Voldemort in a more unique way, combining the magic of the wizarding world with the power of the lightsaber. Maybe he has to go on a quest to learn how to master it fully.
