What are some interesting fanfiction ideas about Percy Jackson's powers of Poseidon?

One idea could be Percy having to face a new threat underwater that only Poseidon can help him understand. Maybe a lost civilization that Poseidon once had a connection with is now causing trouble. Another could be Percy going on a quest to find a powerful artifact that was once Poseidon's but has been stolen, and Poseidon gives him special powers or guidance along the way.

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 idea could be Percy going on a quest that involves uncovering a long - lost secret about his connection to Poseidon that even the gods don't know. Maybe it's a hidden power that only surfaces when he faces a certain kind of threat. Another plot could be Percy having to deal with the jealousy of other demigods because of his special status as Poseidon's son. They might try to undermine him during a crucial mission, adding lots of drama and conflict.

Perhaps in the fanfiction, there could be a prophecy that involves Percy, Zeus and Poseidon. The prophecy states that only when the three of them perform a certain ritual together can they prevent a great disaster. But the ritual requires them to put aside their differences and trust each other completely. Percy has to convince the two powerful gods to participate.

One idea could be her going on a quest to find a lost trident piece that was stolen by a powerful new enemy. This would involve facing various mythical creatures and using her unique powers as Poseidon's daughter.

One idea could be Percy as a baby having small adventures in the underwater world of Poseidon. Maybe he befriends a baby sea monster. Another could be Poseidon trying to protect baby Percy from the other gods who are suspicious of this half - god baby.

One idea could be a fanfic where Sally has a special dream or vision involving Poseidon that gives her some hidden knowledge about Percy's future. For example, she might see a prophecy that only she can interpret and it leads her on a quest to find a lost artifact related to Percy's demi - god status.

A plot idea might be that Percy is magically transported to a time when Poseidon and Hera had a major disagreement in the past. He has to use his wits and powers as Poseidon's son to prevent this rift from growing and causing chaos in the present. Also, he could be given a task by Hera to rescue one of her favored heroes who has been trapped by a sea monster under Poseidon's domain. This would put Percy in a tricky situation where he has to balance his loyalty to his father and the task given by Hera. He might also encounter a group of demigods who are descendants of both Poseidon and Hera in some way, and together they have to face a common enemy.

One idea could be that Percy steals the power of a minor water deity to use against a greater threat. He might struggle with the morality of it at first, but realizes it's for the greater good. For example, he could steal the power to control a specific type of water current that is key to stopping a new breed of sea monsters.

Maybe Percy discovers a prophecy that involves both his father Poseidon and Lupa. He has to journey to different realms under the sea and in the Roman wolf - related places. Along the way, he meets new demigods and creatures that either help or hinder him in fulfilling the prophecy.
