Another plot could be that there is a mix - up between the Greek and Egyptian worlds. Percy, being the son of Horus in this fanfiction, is mistaken for a Greek demigod by some Egyptian deities. This leads to a lot of confusion and misunderstandings. Percy has to clear things up while also dealing with a threat that is looming over both worlds. He has to use his knowledge of both mythologies to save the day.
In this fanfiction, Percy's character arc could be about him coming to terms with his new identity as the son of Horus. He would need to learn about Egyptian culture and mythology. His journey could take him to different places in the Egyptian mythological realm. He might discover new forms of magic or powers that are unique to this new heritage. His friends would also have to adjust to this new Percy, and there could be a lot of drama and adventure as a result.
One idea could be that Naruto discovers his connection to Horus and gains unique powers related to the Egyptian god. For example, he might be able to control the elements in a new way, like using the power of the sun which is associated with Horus. Another plot could involve Naruto having to face an enemy that is also related to Egyptian mythology, and his Horus - related powers are the key to victory.
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 a new water - based monster that is specifically related to the rivers.

Another plot could involve Percy exploring the origins of his connection to the rivers more deeply and uncovering a long - lost prophecy about a'son of the rivers' that changes his view of his destiny.
One idea could be Percy having to face challenges in a world where Gaea has more direct control over the elements.

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.

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.
