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.
One possible plot is that Harry, as a blacksmith, is sought after by all the magical communities. He could create a new kind of portkey that is not only more stable but also has the ability to transport large groups of people at once. His blacksmithing skills could also be used to create a device that can detect dark magic from a distance. This would make him a valuable asset in the wizarding world. He could also hold blacksmithing workshops at Hogwarts, teaching the younger students the art of creating magical items, which would be a great way to pass on his skills and knowledge.
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.
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.
The plot might be that Naruto, as a master blacksmith, is commissioned by the Hidden Leaf Village to create a set of armor for the village's defense. He struggles at first because he wants it to be perfect. Along the way, he has to face off against other blacksmiths who are jealous of his skills and try to sabotage his work. But in the end, he creates an amazing set of armor that can withstand the most powerful attacks.
A Muggle - born blacksmith who discovers the wizarding world and uses his Muggle skills combined with magic he learns to create unique magical items. He could be the main character, struggling to fit in the wizarding world while also making a name for himself as a great magic blacksmith.
One common theme is the creation of unique magical items. The blacksmith in these fanfics often uses their skills to forge things like enchanted swords or powerful amulets. Another theme is the integration of the blacksmith into the wizarding world. They might face challenges in being accepted as a non - traditional magic user but prove their worth.
In such a fanfiction, Harry might raise Naruto in a way that combines the values of both the wizarding world and the ninja world. He could introduce Naruto to the concept of different magical creatures, which Naruto could then try to incorporate into his ninja training. Maybe Naruto would learn how to communicate with magical animals like Hedwig, and use that knowledge to better understand the summons in his own world. Also, Harry could help Naruto with his studies, which would be a huge change for Naruto who wasn't that good at traditional schoolwork at first. This would not only make Naruto more well - rounded but also give him an edge in the ninja world with his new - found knowledge.
One of the most well - known blacksmiths in the Harry Potter universe in fanfiction is probably Ragnuk the First. He was a goblin blacksmith who created some very powerful and famous magical items. In fanfictions, he often plays a more in - depth role, perhaps having secret knowledge or being involved in hidden storylines related to the items he created.
One possible plot could be that a female Kakashi is sent to the Harry Potter world by some sort of magical accident. She then has to figure out how to get back while also getting involved in the fight against Voldemort. She might use her ninja skills and knowledge to help the Order of the Phoenix, like using her stealth to gather information on Death Eaters.
