There could be a situation where a powerful human organization is planning to exploit the resources of the sea in a harmful way. Percy has to find a way to protect the sea and its inhabitants without completely severing his ties with the human world. He could try to negotiate with the humans, using his knowledge of both worlds to come up with a sustainable solution.
A plotline could revolve around Percy discovering his unique powers as the son of Amphitrite. Maybe he has the ability to control not just water, but also the emotions of sea - dwelling beings. This could lead to a story where he has to use this power to calm a raging sea god who is about to destroy coastal cities in a fit of rage. He would have to navigate the complex politics of the underwater realm as well, as there could be factions that either support or oppose his new - found power.
One possible plot could be Percy discovering his true parentage as the son of Amphitrite. He might struggle with his identity, as he has always known Poseidon as his father. This could lead to a journey of self - discovery where he has to learn about Amphitrite's powers and how they are now a part of him.
Well, it could be about Percy having to adapt to his new divine family. Maybe he has to learn special water - related powers from Amphitrite that are different from what he already knows. He could also face challenges from other sea deities who are jealous of his new status.
One possible plotline could be that Shield has been corrupted in this fanfiction. Maybe they see Percy as a threat to their new order or some secret project.

This could lead to Percy being physically and mentally tortured as he tries to resist and figure out a way to break free.
One possible plot could be Naruto having unique water - based powers inherited from Amphitrite. Maybe he can communicate with sea creatures easily. For example, he could use dolphins to gather intelligence or whales to help in battles at sea. This would make him a very different kind of ninja compared to the regular ones in the Naruto universe.
Some of the traditional sea monsters like the Kraken could be antagonists. Since Percy is now in a more prominent position in the sea world as Amphitrite's adopted son, the Kraken might see him as a threat and try to attack him.
One common theme is family. Since Percy is the son of Poseidon and Amphitrite is Poseidon's wife, it often explores how Percy fits into this new family structure. Another theme is power. Percy already has his own powers from Poseidon, and Amphitrite being a goddess also has great power, so how their powers interact is often explored.
He would likely be very strong in water - based powers. For instance, he could have the ability to create powerful whirlpools or tsunamis with ease.

A plotline could involve Percy using his powers, which he may have inherited from Erebus, to fight against some great evil.

He could also be on a journey to discover more about his father and his own place in the world of the fanfiction.
Another plotline could involve Percy having to protect the concept of Order from a powerful antagonist who wants to spread chaos. This could lead to epic battles and Percy having to use his unique connection to Order to defeat the enemy. He might also have to gather allies along the way who believe in the importance of Order.
One possible plotline could be that Leo and Percy are in a dangerous situation together, like being trapped in a magical maze.
