Well, his powers might include not only water - based ones. Since he's a god, he could have some sort of divine influence over weather related to the sea, like creating massive storms or calming them at will. He might also gain the power to transform into different sea - related forms, such as a giant sea monster or a merman - like being. And his healing ability, which was already there because of his connection to water, could become so strong that he could revive the dead if they had a connection to the sea in some way.
One of the new powers could be the ability to control all forms of water in a much greater scale. Not just the sea, but also clouds, rivers, and even the water in living beings. This would make him extremely powerful as water is everywhere. He could use this power to create massive tidal waves or to heal by manipulating the water within a body.
It would be extremely powerful. You could have control over various elements like the gods in the Percy Jackson world. For example, if reborn as a water - related god, you might be able to manipulate all forms of water, from the tiniest droplets in the air to vast oceans. And you'd get to interact with the other gods and demigods in a whole new way, perhaps changing the course of events in the fanfiction world.
It would probably be full of epic battles. Percy, as a god, would bring his water - based powers to the Avengers. He could use his powers to control water sources during battles, like creating huge tidal waves to stop enemies. And his connection to the Greek gods could introduce a whole new mythology aspect to the Avengers universe.
It would be an amazing experience. You'd have incredible powers, like being able to control the elements or manipulate time. You could interact with all the beloved characters from the Percy Jackson universe in a whole new way. Maybe you'd be a new god, bringing in fresh ideas and changes to the pantheon. And you'd get to see the world of Camp Half - Blood and the other mythical places from a divine perspective.
In a fanfiction where Percy is secretly a god, his relationships with other gods would be turned upside down. Initially, the other gods would be shocked and perhaps a bit resentful that a demigod has ascended to godhood. This could lead to some tension, especially among the more prideful gods. However, over time, Percy could form new alliances. He might work with gods who share his values, such as those concerned with the protection of the natural world. His relationship with his father Poseidon would also change, becoming more of a peer - to - peer bond rather than a father - son relationship with a power imbalance. And with the other Olympians, he would need to navigate the complex politics of the divine world, which would be a whole new experience for him.
He could have the power to freeze water instantly. Since he has a connection to water already as a son of Poseidon, this would be an extension of that. He might also be able to create ice storms and blizzards at will.
It could be really exciting. Percy might use his water - controlling powers in the God of War universe. He could face off against the fearsome creatures from God of War like the Minotaur in a whole new way. Maybe he'd team up with Kratos and use his quick - thinking and strategic skills along with Kratos' brute strength.
In 'Percy Jackson Born a God Fanfiction', Percy could have a very different upbringing. Since he's born a god, he might not face the same kind of discrimination or danger that normal demigods do. He could be raised in Olympus, learning the ways of the gods from a very young age. His relationships with other characters would also be transformed. For example, Annabeth might view him more as an equal to the gods she admires rather than just a fellow demigod. His adventures would likely be on a much grander scale, perhaps involving saving the entire universe in a more direct way compared to his demigod self.
His relationship with Annabeth would likely change. She might be both in awe and a bit worried about his new powers. For example, if Percy can now control wild animals, she might be concerned about how he uses that power in battle. On the other hand, Grover would be extremely excited. Grover has always had a connection with nature and animals, and now Percy being the god of animals would make their bond even stronger. They could go on more adventures together, exploring hidden animal habitats.
He might become more aloof. Being a god often comes with a sense of superiority, but Percy has always been down - to - earth. However, his new status could make him a bit more distant from his mortal friends at first. But deep down, he'd still be the same Percy with a strong sense of right and wrong.
