Perhaps Naruto would revolutionize the blacksmithing industry in the ninja world. He could introduce new alloys or techniques. Since he has a lot of energy and creativity, he might come up with new types of weapons that are more effective in combat. He could also teach other young ninjas the art of blacksmithing, creating a new generation of weapon - making ninjas.
In such a fanfiction, Naruto might use his new blacksmith skills to create unique weapons for the characters in the yaoi relationships. He could forge special items that symbolize the bond between the male characters. For example, he might make a pair of matching daggers for a couple, each with an engraving that represents their love for each other.
He might become more patient. Blacksmithing requires a great deal of patience, and this could seep into his personality. He would have to be meticulous in his work, which could make him more detail - oriented in his interactions with others as well.
In Naruto fanfiction, the combination of Fuinjutsu and blacksmithing can be really interesting. Fuinjutsu is all about sealing techniques, and when combined with blacksmithing, one can imagine creating weapons with sealed powers. For example, a sword that has a sealing jutsu inscribed on it to trap the opponent's chakra when it strikes. It adds a whole new layer of creativity to the Naruto universe.
In such fanfiction, the blacksmith could be a master of both metal and seals. They might create a chain with Fuinjutsu that can bind an opponent's chakra. This would be a great addition to a ninja's arsenal. They could also work on larger items like gates with Fuinjutsu seals to protect a village or a secret location.
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.
I think the 'godlike naruto is a blacksmith fanfiction' is likely centered around Naruto having god - like qualities and applying them to the art of blacksmithing. He could be forging items that have special powers or significance. For example, he might be making weapons that can only be crafted by someone with his level of strength and skill. It could also show how he changes the perception of blacksmithing in the Naruto universe.
First, Harry would need to learn the basics of blacksmithing, which could be a bit tricky as he's used to waving a wand. But his quick learning skills from Hogwarts would help. He might combine his knowledge of spells and potions to create new alloys. His work as a blacksmith could also attract the attention of dark wizards who want to steal his creations, leading to some exciting adventures.
One idea could be a blacksmith who creates unique ninja tools with special abilities that give the wielder an edge in battle. For example, a kunai that can change its shape during flight to avoid enemy defenses.
