One idea could be Percy discovers a new power related to controlling time and tides that was hidden from him all along. Maybe he can freeze time during a battle to gain an upper hand against his enemies. Another plot could involve Percy traveling through different time periods using his newfound god - like abilities to correct past mistakes in the world of the gods.
Well, a great plot could be that Percy, as the God of Time and Tides, has to deal with the consequences of messing up the natural order of time. For example, he accidentally speeds up time in one area, causing plants to grow and die in a matter of minutes, and animals to age rapidly. He then has to find a way to reverse it while also facing the wrath of other gods who think he's overstepping his boundaries. This would involve a lot of action, self - discovery, and interaction with other characters from the Percy Jackson universe.
Well, in certain fanfictions, Percy as the God of Tides might have a different relationship with the sea creatures. He could communicate with them on a deeper level, almost like he's their supreme leader. For example, he could summon giant sea serpents to do his bidding or have schools of fish form elaborate patterns in the water to send messages to other gods or demigods.
One idea could be Percy using his new powers to travel through different time periods in the demigod world and fix historical disasters. For example, he could go back to the time of the Titan War and prevent certain events that led to great losses. Another plot could involve him exploring different dimensions in space, finding new and strange mythical creatures that exist only in those far - off realms. He might also have to deal with the consequences of messing with time, like creating alternate timelines that start to collide with the original one.
One interesting plot idea could be Percy traveling back in time to the era when the gods first came to power. He could witness the creation of the Olympian council and get involved in the early power struggles among the gods. Another idea is that a god sends Percy on a time - travel mission to fix a mistake in the past that is now threatening the present world of demigods. For example, if a powerful magical artifact was lost in the past and its absence is causing chaos in the present.
Many fanfictions also have a plotline where Percy as the God of Tides has to deal with the consequences of his new power. He might accidentally cause a natural disaster due to his inexperience with his godly abilities. Then, he has to find a way to fix it while also facing the wrath of the other gods who are angry about the disruption he has caused.
It could be an ancient being that was locked away for centuries but has now been released due to Percy's meddling with time and tides. This being might have a vendetta against the gods in general and sees Percy as a key to achieving its revenge. It could have the power to manipulate time in a different way than Percy, causing all sorts of chaos and destruction. For example, it could create time loops that trap people in never - ending cycles of pain and suffering, and Percy has to figure out how to break these loops and stop the being.
One idea could be exploring a new adventure where Percy has to team up with a minor god that has been forgotten. They could go on a quest to regain the forgotten god's power and status in the pantheon.
Perhaps Percy, as the God of Wisdom, has to deal with a situation where his wisdom is being questioned by the other gods. They don't believe that a former hero like him can handle the responsibilities of wisdom. So he has to prove himself by solving a complex problem that has been plaguing Olympus for centuries. He uses his unique perspective as a demigod - turned - god to come up with a solution that no one else could think of.
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.
Perhaps Percy, as the God of the Earth, has to plant the seeds of a new magical forest to restore balance to the world. But an evil force is trying to stop him by sending monsters to attack him and the forest he is trying to create. He has to use his earth powers to defend and also enlist the help of nature spirits like dryads. He also discovers that this new forest has a connection to an ancient prophecy that could change the fate of the world.
A great plot idea could be Percy Jackson being transported to the world of God of War and having to adapt to its harsher rules. He'd have to learn to fight without relying solely on his water powers, as the enemies there are more fierce and less predictable. Maybe he gets mistaken for an enemy by Kratos at first and has to prove himself.
