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.
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.
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.
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.
In fanfiction, if Percy Jackson is the God of Water, his relationships would change. For example, his relationship with Annabeth would be different. There could be a power dynamic shift as he becomes a more powerful entity. She might have to adjust to his new status, and there could be some interesting tension and growth in their relationship.
The idea of Percy as the God of Space opens up a whole new world of possibilities. For instance, his relationship with other gods would change drastically. Gods like Zeus, who are used to being in control of the sky (which is related to space in a way), might see Percy as a threat or a new ally. Percy's adventures would no longer be just limited to the Earth or the known mythological realms. He could travel to distant galaxies and encounter new and strange creatures, and his demigod nature might be the key to interacting with these extraterrestrial beings.
In some fanfictions, Percy could become the God of Time himself. This would lead to a whole new set of powers and responsibilities. He might have to manage the flow of time, which could include stopping time - thieves or those who try to manipulate time for their own evil purposes. His friends would then have to adjust to this new, all - powerful Percy, and there could be conflicts arising from the change in his status.
In fanfiction, Percy Jackson as the God of Emotions could be really interesting. He already has a deep well of emotions from his normal adventures. As a god, he might be able to sense and manipulate the emotions of others. For example, he could use his new powers to calm his friends in times of distress or even incite courage in them during battles.
Well, it really depends on the specific fanfiction. There are countless fanfictions out there about Percy Jackson. Some authors might choose to elevate him to god status as a way to explore different aspects of his character, like how he would handle immortality or the responsibilities that come with being a god. They could also do it to create interesting new power dynamics within the Percy Jackson universe.
Another plotline could involve Percy making a deal with the God of Death. In this scenario, he has to fulfill certain tasks in exchange for something he desperately needs, like saving a friend's life. This would put him in a series of dangerous and morally challenging situations as he tries to complete the tasks without sacrificing his own values.
Some fanfictions might explore what would happen if Percy had a different parentage. Maybe he was the son of a different god or goddess, like Hecate. This would completely change his powers and the way he interacts with the magical world around him. He could learn new types of magic and have a whole new set of challenges and adventures.
