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.
Well, Naruto is the main focus. But there could be other characters related to Hephaestus. Maybe some of Hephaestus' servants or creations in the fanfiction. They could either be friends or foes to Naruto. And of course, the antagonists in the Naruto world would also be main characters in a sense. They would be the ones against whom Naruto uses his new powers as the son of Hephaestus to fight and protect his village and friends.
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.
Sometimes, other gods and goddesses make an appearance. Athena might show up to collaborate with Hephaestus on a project. Their interactions can add a lot of depth to the story. For example, they might have different ideas on how to create a new weapon, and their debates and compromises can be really interesting to read about. And of course, there could be a villainous god who tries to steal Hephaestus' secrets related to his snaps.
His relationship with Sasuke would likely be different. Naruto's charm from Aphrodite might make Sasuke less hostile towards him initially. And his skills from Hephaestus could make Sasuke respect him more as a strong opponent. For example, if Naruto creates a really powerful weapon, Sasuke would see him as a worthy rival in a new light.
