What could happen in a fanfiction where Percy Jackson is friends with Hades?

Well, if the gods in the Percy Jackson universe were to read 'House of Hades' fanfiction, there could be a lot of chaos. Some gods might be amused by the creative interpretations of their characters. For example, Zeus might be both irritated and intrigued to see how mortals imagine his actions and relationships. He could either decide to punish those who wrote unflattering things or just chuckle at the absurdity.

Well, Percy might gain new powers related to the Underworld. Since Hades is the god of the Underworld, he could teach Percy how to control shadows or communicate with the dead. This would make Percy an even more formidable demigod, with abilities that no one else has. He could also face a lot of challenges from other gods who might be jealous or scared of his new connection to Hades.

Maybe Percy discovers that there is a conspiracy within the Underworld to overthrow Hades. As the champion, he has to uncover the truth and stop the plot. Along the way, he meets old enemies who now see him as an ally of Hades and try to take advantage of the situation.

Hestia could use her power over the hearth to protect Percy and his friends. For instance, when they are in a dangerous situation, she might create a protective barrier around them using the warmth and energy of the hearth.

Well, Percy might be really confused at first. If Milner is some sort of mystery figure, Percy could be on guard. Maybe he thinks Milner is a threat from another mythological realm. He'd probably have his sword ready just in case.

In the 'Percy Jackson Disappears' fanfiction, perhaps Percy could be kidnapped by an unknown enemy. Maybe it's a new villain who has a vendetta against the demigods. This would lead to his friends, like Annabeth, going on a desperate search for him, facing many dangerous challenges along the way.

In fanfiction, Percy could be in the hospital because he was captured by an enemy and tortured. Now he's there being healed by the camp's healers or some advanced demigod medical technology. Another possibility is that he's having some sort of identity crisis related to his demigod status and it's causing him physical and mental stress, so he's in the hospital for both medical and psychological help.

One possible plot could be Percy struggling with the duality of his parentage. He might face discrimination from both the children of Hades and Poseidon. For example, the children of Poseidon could see him as a threat because of his connection to Hades, and vice versa. He could then go on a journey to prove that his dual heritage doesn't define him, but rather gives him unique powers to protect the world of the gods and mortals.

Well, in this fanfiction, Percy's immortality could lead to some really interesting character development. He may start to feel lonely as he realizes that he will outlive all of his friends. This could cause him to be more withdrawn at first. But then, as he interacts with the students at Westover Hall, he might find new meaning in his immortality. He could start to see it as a way to protect others not just for a short time, but for as long as he exists. He could also form deep and lasting friendships with those who accept him for who he is, regardless of his immortality.

In the fanfiction, Percy might face new challenges related to his demigod status. Maybe he has to deal with the aftermath of the war, like rebuilding Camp Half - Blood or helping new demigods adjust.
