One interesting plotline could be a power struggle between Triton and Percy, with Poseidon caught in the middle. Maybe Triton feels threatened by Percy's newfound status as a demigod son of Poseidon and tries to undermine him.
There could be a plot where Percy has to prove himself to Triton. Triton might initially doubt Percy's loyalty to the sea and Poseidon. So Percy goes on a quest to retrieve a lost artifact of the sea that only he, with his unique demigod abilities, can reach. This would not only show his loyalty but also earn Triton's respect. It could also be a story about Percy learning more about his father's underwater world through Triton, who has a different perspective compared to Poseidon, as Triton has been in the sea realm all his life while Poseidon has many other responsibilities on land and in Olympus.
One possible plotline could be Percy facing a new and extremely powerful sea monster that Poseidon can't directly interfere with, but through their unique father - son bond, Poseidon gives Percy hidden powers that help him in the fight. Another could be Percy exploring an ancient underwater kingdom that Poseidon has long kept secret, and there are many challenges and revelations along the way.
Triton is often an interesting character in these fanfictions. He has his own insecurities and ambitions. Some fanfictions write him as a jealous character, feeling overshadowed by Percy. But in other well - written ones, he is shown as a complex figure who has his own reasons for his actions and eventually comes to terms with Percy. His knowledge of the sea and his relationship with Poseidon also offer a lot of potential for character development.
One idea could be Percy exploring an underwater realm that only Poseidon can access. He discovers ancient secrets about his father's past and the origin of his powers. Another could be a story where Percy has to team up with Poseidon to fight a new and powerful sea - born enemy. Maybe there's a prophecy that only their combined strength can fulfill.

One interesting storyline could be their adventures together in the underwater world. Maybe they discover a long - lost Atlantis - like city. Triton and Percy could team up to fight off some new sea monsters that are threatening the peace of the ocean. Another could be about how they learn from each other's powers. Percy, with his connection to water from Poseidon, and Triton, being a sea god, could exchange knowledge and techniques.
One common type of story in 'Percy Jackson Son of Triton Fanfiction' is where Percy has to face an ancient evil that was only hinted at in the original books. He might use his powers in new and creative ways, like combining his water - controlling abilities with some other hidden talent.
