Well, it could mean a huge power shift in the Percy Jackson universe. Percy already has a lot of power, and absorbing Ouranos might make him almost god - like. It could also lead to new conflicts, as other characters might fear his newfound strength or try to use it for their own gains.
Percy would likely become more confident, given the immense power he's gained from absorbing Ouranos. He might also become more solitary, as he tries to understand and control this new power within him.
Well, it could mean a huge power boost for Percy. Hyperion is a powerful Titan, so Percy might gain abilities like enhanced strength, maybe some new control over light or the sun. It could also change his status among the demigods, making him even more of a force to be reckoned with.
One possible plot could be Percy's discovery of his true parentage. He might struggle with the implications of being the son of two powerful primordial deities. For example, he could face a conflict between the forces associated with Ouranos and Gaea. This could lead to him having to make difficult choices about which side to support, if any. And he may also have to deal with the reactions of his friends and the other demigods who might view him differently now.
Maybe some rogue demigods who are power - hungry. They see Percy's new title as Champion of Ouranos as a way to gain ultimate power. So they would try to either take the title from him or prevent him from using his powers. They could form a secret group and plot against Percy, using their own demigod abilities and knowledge of the demigod world to their advantage.
Maybe there's a plot where Percy has to team up with other demigods who also have primordial roots. Together, they have to face a great evil that is threatening to destroy the balance between the primordial and Olympian worlds. They would have to use their combined powers and knowledge to save both worlds.
It could involve Percy having new and powerful abilities. Since Ouranos is a primordial god, Percy might have control over fundamental elements like the sky or the very essence of creation. For example, he could be able to manipulate the air in ways he couldn't before, like creating powerful storms or even pockets of different atmospheres.
His relationship with Annabeth would likely become more complex. She might be a bit worried about Percy's new powers and what they could mean for his safety and their future together. But at the same time, she would be there to support him as always.
Well, in some fanfictions, Percy might absorb power through a magical artifact. For example, he could touch an ancient relic that transfers its energy to him. This could be a way to give him new abilities or enhance his existing ones like his water - controlling powers.
Well, if Percy Jackson absorbs Gaea in fanfiction, it could lead to a really interesting plot twist. Percy already has a lot of power with his control over water, but adding Gaea's essence would be something else entirely. He might start to have visions related to the earth's history and future. And his personality could change too, perhaps becoming more stoic or more in tune with the natural cycles of the world as he now embodies a part of the earth goddess.
