Well, in such a fanfiction, the story could start with a big revelation about his true parentage. Harry could struggle with his new identity. He might have to deal with the politics of the Underworld as well as the wizarding world. His relationships with characters like Dumbledore and Voldemort would change drastically. For example, Voldemort might be more afraid of him because of his connection to Hades. And Harry could also have some new allies from the Underworld, like the Furies or Cerberus. It would be a whole new adventure with a darker and more complex Harry Potter.
It would probably be full of interesting twists. Harry might have some dark powers from Hades, like the ability to control the dead. His character could be more brooding and less naive compared to the original.
A 'Harry Potter is the son of Hades' fanfiction would likely be a wild ride. Firstly, Harry's appearance might change, maybe having a more otherworldly or shadowy look. His magic would be different, perhaps more related to death and the afterlife. His connection to Hades could mean he has access to the Underworld, and he might use it to his advantage in battles against Voldemort. His friends, like Ron and Hermione, would have to adjust to this new Harry. They might be initially shocked but then support him as he discovers more about his heritage. The story could also introduce new villains from the Underworld who are jealous of Harry's connection to Hades or want to use him for their own evil plans.
