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.
There's a chance that a visiting wizard from a far - off land could be his mentor. This wizard could come from a place where the magic is more closely related to the technology of lightsabers. He brings with him new spells and techniques that are essential for Harry to build and master the lightsaber. He also teaches Harry about the cultural significance of such a weapon in their magic system, which gives Harry a deeper understanding of what he's creating.
Well, perhaps Harry Potter discovers some ancient magic that allows him to combine the wizarding world's technology with that of the Star Wars universe. He might use his knowledge of spells to power the lightsaber in a unique way, like using the Lumos spell to create the blade instead of the traditional kyber crystal. He could then face off against Voldemort with this new weapon, creating a whole new dynamic in their battles.
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.
Perhaps Hagrid could be his mentor. Hagrid has a lot of knowledge about magical creatures and their parts, which could be useful for Harry in his blacksmithing. He could show Harry how to use things like dragon scales or unicorn hairs in his creations.
Dumbledore could be his mentor. He has vast knowledge and experience, and he would likely see the potential in Harry being an Animagus. He could guide Harry through the difficult process of learning to control his transformation and use his Animagus form for good.
Dumbledore might help in a spiritual or advisory way. Even though he's passed away, his wisdom could be passed on through memories or some magical means. Also, Hagrid could be a great help. He could assist in building areas suitable for magical creatures with his love and understanding of them.
His friends Hermione and Ron would most likely be his allies. They have been with him through thick and thin in the original series.
Hermione would be a great help. Her vast knowledge of magic and books could provide the necessary information for building the planet, like the right spells and magical theories.
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.
His character could develop in terms of leadership. As he is building the ship, he has to take charge and make decisions. This would make him more confident in his leadership abilities.
Ron could also be a great ally. His loyalty and courage would be important. He might be in charge of security, using his skills in wizard chess to plan out defensive strategies. And of course, the Weasley family in general could offer a lot of support, with their various skills and connections in the wizarding world.
