One possible plot could be Naruto having special powers related to Hephaestus. Maybe he has an innate ability to create and manipulate advanced weapons. For example, he could use his chakra in a unique way to forge swords or other tools that have special properties. This would give him an edge in battles against powerful foes in the Naruto universe.
The plot could involve Naruto struggling with his dual heritage. On one hand, he has the creative and mechanical genius of Hephaestus. So he might be interested in building advanced ninja tools. On the other hand, his Aphrodite side gives him an allure that he doesn't know how to handle. This could lead to some comical or even dangerous situations as other characters react to his charm in different ways.
Well, one possible plot could be that as the son of Hephaestus, Harry might have an extraordinary talent for creating magical artifacts. He could use his skills to help in the fight against Voldemort. For example, he might create some sort of enchanted weapon that can nullify the Dark Lord's spells.
Maybe Naruto could be reborn as Hephaestus in a different world. He'd use his ninja skills along with Hephaestus' godly powers, like forging amazing weapons in a unique way that combines Naruto's chakra control and Hephaestus' smithing abilities.
Naruto is the central character for sure. In addition to him, there could be characters from Greek mythology who cross over into the Naruto universe. For example, Athena might come to Konoha to check on the son of Hephaestus. And Naruto's sensei, like Kakashi, would also play a crucial role as he tries to help Naruto understand and control his powers that come from his relation to Hephaestus.
The plot might revolve around a conflict. Hephaestus discovers some secrets about Hera that she wants to keep hidden. Since Hephaestus is known for his intelligence and resourcefulness, he could use this knowledge to his advantage. However, instead of using it to harm Hera, he could offer to keep her secrets in exchange for a better position in the divine hierarchy. This would create a tense yet interesting dynamic between them.
One important thing to note is the character development. Since it's a crossover, how the Naruto characters interact with the elements related to Hephaestus' son should be carefully observed. For example, how Naruto might use skills or tools related to Hephaestus in a way that still fits his original character. Another thing is the plot consistency. The fanfiction should have a logical flow that combines the Naruto world and the concept of Hephaestus' son without creating too many plot holes. Also, the writing style of the author can greatly affect the reading experience. If it's too convoluted or hard to understand, it might be a drawback.
Well, in this fanfiction, it could be that Hephaestus trains Harry Potter to have a better understanding of the more physical and mechanical aspects of magic. For example, he might learn to build magical devices that can be used in battles or for other important tasks. This would give Harry an edge over his enemies as he'd have skills that no other wizard has. It could also lead to new alliances as other wizards might be interested in his newfound abilities.
A plot might involve Hephaestus creating a magical item for Aphrodite as a gift. This item has the power to make her see the world from his perspective. As she experiences his life through this magical object, she realizes how much he truly loves her and the sacrifices he has made. This newfound understanding makes her fall in love with Hephaestus in a way she never thought possible, and they start a new chapter in their relationship.
Well, one possible plot could be that Percy discovers his new relation to Hephaestus later in his adventures. He might then start to have an affinity for creating and fixing magical items, which could be a new skill for him in battles against monsters. He could also meet other descendants of Hephaestus who teach him more about his heritage.
One possible plot could be centered around Hephaestus finding out about Aphrodite's affairs and his journey of dealing with his emotions. Maybe he decides to confront her in a more modern - day setting where the gods have to adapt to human - like social norms.
