Fanfiction about Harry, the grandson of Hades: What are some interesting plot ideas?

A possible plot could involve a magical object that has connections to both the Harry Potter world and the realm of Hades and Persephone. For example, a magical flower that can only grow in the underworld but has the power to heal the most deadly of curses in the wizarding world. Harry, along with Persephone and Hades, has to protect this flower from those who would use it for evil.

One plot idea could be Harry discovering his true parentage and having to deal with new powers that come with being Hades' son. He might struggle to control the power of the underworld, like being able to summon the dead or manipulate shadows.

One plot idea could be Hercules having to make a deal with Hades to save a loved one. For example, he might have to complete a series of impossible tasks in the Underworld. Another could be Hades trying to recruit Hercules to his side, offering him power in exchange for loyalty. Maybe a story where Hercules discovers a long - hidden secret about Hades' past that changes their dynamic.

One idea could be exploring Persephone's adjustment to the Underworld. For example, she could start a garden in the gloomy realm using her powers over plants, which not only changes the look of the Underworld but also the attitude of its inhabitants. Another plot could be Hades trying to court Persephone in a more modern way, like taking her on a tour of different parts of the Underworld that are beautiful in their own dark way.

One idea could be exploring the backstories of the minor characters in the House of Hades more deeply. For example, delving into the history of some of the shades that are often just in the background.

One plot idea could be that Hades and Maleficent team up to take over the magical realms. They combine their dark powers and start by causing chaos in the fairy kingdoms. Another could be a love story where they initially clash but then find common ground and fall in love, changing their evil ways for each other. Maybe they could also form an alliance to fight a greater evil that threatens both their domains.

Well, you could have a plot where Persephone and Hades have an argument over her time split between the Underworld and the upper world. This could lead to her leaving for a while and Hades having to go through a series of trials to win her back. Another idea is that they discover a new part of the Underworld together that has been locked away for ages and it holds a great power. They must figure out what to do with this power without causing chaos in both their worlds.

In this fanfiction, perhaps it delves into the character development of the 'consort of Hades' within the context of the Harry Potter world. This character might have to navigate the complex social structures of Hogwarts while also having ties to the underworld. They could introduce new forms of magic or ways of thinking that are a blend of both realms.

One plot idea could be Mal struggling to fit into the Underworld society that Hades rules. Since she's from a different world in Descendants, adapting to the dark and often chaotic nature of the Underworld could be full of challenges and interesting character developments.

One idea could be Percy having to navigate the Underworld politics due to his relation to Hades. He might face challenges from other underworld creatures who don't trust him. Another could be Percy using his newfound powers as the son of Hades to fight against an ancient evil that threatens both the mortal and underworld realms. Or perhaps he has to deal with the stigma of being Hades' son in the demigod community and prove himself worthy.
