One possible plot could be Percy's struggle with his dual heritage. He might be conflicted between the gentle, love - associated nature of Aphrodite and the powerful, tempestuous nature of Poseidon. He could be an outcast among both the children of Aphrodite, who are often more focused on beauty and charm, and the children of Poseidon, who are known for their strength and connection to the sea. This internal struggle could form the basis of a great adventure as he tries to find his place in the world of demigods.
In this fanfiction, Percy could be caught in a love triangle of sorts. With Aphrodite as his mother, love and relationships might be more complicated for him. Maybe he falls in love with a mortal, but Aphrodite has plans for him to be with a demigod who can help strengthen the power of their family line. This would create internal conflict for Percy as he has to decide between following his heart or fulfilling his 'duty' in this fan - created family dynamic.
He could have adventures that involve both the sea and matters of the heart. For instance, he might be sent on a mission to retrieve a magical item from a sunken city. But, along the way, he has to use Aphrodite - like powers to charm the sea creatures guarding the item. He could also encounter mermaids who are under a spell of jealousy, and he has to use his combined powers to break the spell.
His powers would be a blend of two very different deities. While still having control over water like the original Percy, he might be able to use his Aphrodite - related powers in combat. For example, he could use his charm to disorient opponents or make them more vulnerable. Also, his connection to the sea might be different. Instead of just controlling the water, he could perhaps make the sea seem more alluring or beautiful, which could be a new form of defense or attack, luring enemies into a false sense of security.
In fanfiction, the Son of Aphrodite could also have an interesting love life. Since Aphrodite is the goddess of love, her son might have a complex relationship with love. He could be a hopeless romantic, constantly falling in and out of love. Or he might be cynical about love, having seen the chaos it can cause, especially among the demigods.
Percy, son of Aphrodite, was an enigma in Camp Half - Blood. He didn't quite fit the mold of a typical Aphrodite kid. While others focused on beauty and charm, Percy was more interested in the art of combat. One day, he was challenged by a bully from Ares' cabin. Instead of using his charm to defuse the situation, Percy picked up his sword. His eyes blazed with determination as he faced his opponent. With swift and precise moves, he disarmed the bully, leaving everyone in shock. This act made him a bit of an outcast among his own siblings but earned him respect from the other campers.
Percy could have the power of enhanced beauty. Not just in a physical sense, but a kind of allure that draws people to him. This could be used in various ways. He might be able to use it to charm his way into getting information from people who are normally very guarded. Or, in a more positive way, he could use his allure to bring people together. For instance, if there were two feuding groups in the camp, his presence could make them more open - minded and willing to listen to each other, simply because they are attracted to his unique charm.
There's also a fanfic called 'Poseidon's Promise'. In this one, Percy has to deal with a mysterious prophecy related to his father. The story is full of twists and turns. It delves deeper into the relationship between Percy and Poseidon, which is really interesting to read about. It also has some great action scenes with Percy using his water - based powers.
One idea could be Percy feeling betrayed by Poseidon and then finding a new family among other outcasts in the demigod world. He could form a group with them and go on adventures that are not related to Poseidon at all.
Yes, there are many great ones. You can start by looking on fanfiction websites like Archive of Our Own. Some focus on Percy's new adventures that draw on his unique heritage as the son of both Poseidon and Neptune, exploring how he might handle different mythological challenges.
