What are some interesting plot ideas for Percy Jackson Son of the Rivers fanfiction?

Well, a great plot idea might be Percy getting involved in a sky - realm war. He has to use his newfound 'Son of the Sky' abilities to lead an army of sky creatures against an evil force. This would involve him making alliances with different beings, like the winged horses or the cloud nymphs. And he'd have to learn how to fly better to be more effective in the battles. Also, his relationships with his friends from Camp Half - Blood would be put to the test as they might not fully understand his new role.

One idea could be Percy discovers a new, forgotten power related to his 'son of love' aspect. Maybe he can heal emotional wounds of other demigods. For example, he helps a demigod who has been traumatized by past battles by using this power.

One idea could be Percy having to prove his divinity in a new way. Maybe he has to face a trial set by the gods where he can't use his usual powers but has to rely on his wits and faith. Another could be Percy interacting with a different pantheon's deities who mistake him for one of their own sons of god. He'd have to navigate their culture and rules.

One idea could be Percy having to face challenges in a world where Gaea has more direct control over the elements. For example, the earth itself could be constantly shifting and changing, creating new terrains and obstacles for him to overcome. Another could be Percy forming an unlikely alliance with some of Gaea's other children who are also having second thoughts about their mother's destructive plans.

One idea could be Percy having to hide his true parentage from his friends at Camp Half - Blood. He might struggle with the dark powers that come with being Typhon's son while trying to fit in with the demigods who are mostly children of the Olympians. Another plot could involve Percy being hunted by both the Olympians and the monsters because of his unique heritage. The Olympians might see him as a threat, and the monsters might want to use him for their own purposes.

One idea could be Percy discovering new powers related to being the son of Persephone. For example, he might be able to control plant growth in unique ways during battles, like making vines entangle his enemies. Another could be his relationship with the Underworld changing. Since Persephone has a connection to the Underworld, Percy might have a special status there and encounter new mythological creatures or challenges.

One idea could be Percy having to face a new and powerful monster that is immune to water. This would really challenge his typical combat strategies. Another could be Percy getting lost in a forgotten part of the Underworld and having to find his way out while dealing with various underworldly spirits.

Another plot could be Percy discovering a long - lost relative among the children of Hades. This relative has some sort of power or knowledge that could change Percy's understanding of his own identity and his place in the demigod world. It could lead to a journey of self - discovery for Percy as he navigates this new family connection within the dark and often misunderstood realm of Hades.

One idea could be Percy having to use his charm powers (from being Aphrodite's son) to charm a powerful, ancient monster into sparing a group of demigods. He might struggle with the morality of using such powers in this way.

One idea could be Percy using Wolverine's healing factor during a particularly tough battle in the world of Greek mythology. Maybe he gets injured by a powerful monster and the unexpected emergence of the healing ability saves him and surprises his friends.
