What could be an interesting plot in a Harry Potter is a blacksmith fanfiction?

One possible plot could be that the Naruto world is facing a new threat that can only be defeated by unique weapons. Harry Potter, the blacksmith, arrives in the Naruto world. He starts to study the materials and techniques available in this new world. He combines his knowledge of magic - enhanced blacksmithing with the ninja's understanding of chakra. As he creates these new weapons, he also forms bonds with the Naruto characters. They train together to master the use of these new weapons, and ultimately they face the great threat together, with Harry's blacksmith - made weapons playing a crucial role in the victory.

It could be an old wizard who has been living in seclusion for centuries, perfecting his smithing skills. He might emerge during a time of great need in the wizarding world, like when Voldemort was at his most powerful.

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.

Perhaps a godlike blacksmith in Harry Potter fanfiction has the ability to infuse emotions into their creations. So a piece of armor they make might give the wearer courage or a sense of calm. This would add a new dimension to the magical items in the Potterverse, as they usually just have more straightforward magical functions.

I'm not entirely sure if there is a specific one with that exact premise. However, fanfiction authors are constantly coming up with new and unique concepts. Given the popularity of both Harry Potter and Naruto, it's possible that someone has written a story where Harry Potter is a blacksmith within the context of a Naruto fanfiction. It could be an interesting take on the characters and their worlds, perhaps exploring how Harry's skills as a blacksmith could interact with the ninja world of Naruto.

Well, perhaps the Omnitrix gets mixed up with the magic in Hogwarts. It starts malfunctioning and instead of the usual alien forms, it gives Harry forms of ancient wizards. He has to figure out how to control these new forms while also dealing with the mystery of why the Omnitrix is acting this way. And he might learn new spells and magic from these wizard forms.

One idea could be that Palpatine somehow discovers the wizarding world of Harry Potter. Maybe he sees it as a new realm to conquer. He could try to manipulate the Ministry of Magic using his Sith mind - tricks, and Harry Potter would have to figure out who this strange new threat is and stop him. It would be a clash of two very different kinds of magic.

Maybe in the 'Harry Potter in Undertale fanfiction', Harry discovers that Voldemort has also found his way into the Undertale world and is trying to gain power there. Harry has to learn the rules of this new world quickly. He befriends Sans and Papyrus. Sans, with his knowledge of the resets in Undertale, helps Harry understand how to manipulate time in a way that could give him an edge against Voldemort. Papyrus, on the other hand, is enthusiastic about Harry's magic and they train together to fight off Voldemort's minions in the Undertale world.

Another plot could be that Voldemort discovers Powergirl's existence and sees her as a threat. He tries to manipulate the wizarding world against her. But Harry and his friends believe in her and together they work to expose Voldemort's lies and also learn from Powergirl about different ways of fighting evil. Powergirl could introduce new concepts of justice and heroism to the wizarding world.

One possible plot could be that the Kubikiribocho, the sword in Naruto, somehow finds its way into the Harry Potter universe. Harry discovers it during one of his adventures in the Forbidden Forest. He initially has no idea how to use it but gradually realizes it has some unique powers that can be harnessed against Voldemort. For example, it might be able to cut through dark magic spells. However, there are also some negative aspects to the sword as it tries to corrupt Harry a bit, just like the influence of the Horcruxes. Harry has to fight against this internal battle while also using the sword's power to defeat Voldemort.
