There could be some characters from Ouranos' world who turn out to be allies. Maybe there are some celestial beings who recognize Naruto as the son of Ouranos and decide to help him. For instance, a being with the power to manipulate time could assist Naruto in his battles or in understanding his powers better. Additionally, Hinata could be a strong ally. She has always had feelings for Naruto and would surely stand by his side, using her Byakugan to help him in combat and in uncovering secrets related to his new identity.
The plot might involve Naruto discovering his true father, Ouranos. He could then go on a journey to learn more about his father's world and powers. Along the way, he might face challenges from those who don't want him to embrace his heritage. For example, some of the shinobi in the village might be afraid of his new - found powers and try to stop him. Also, he could meet other characters related to Ouranos who help or hinder his progress.
Percy, son of Ouranos, stood on the cliff overlooking the vast expanse of the ocean. His eyes, a deep shade of blue like the sea itself, held a glint of determination. He knew his lineage was special, being the son of the primordial god Ouranos. He felt a connection to the skies above and the waters below. With a deep breath, he raised his hands, and the wind began to stir around him, as if answering his call. He was ready to face whatever challenges lay ahead, to prove himself worthy of his divine heritage.
Well, in this 'Harry Potter Son of Ouranos' fanfiction, perhaps it explores how Harry's connection to Ouranos gives him unique powers. Maybe he can control certain elements or has a special bond with ancient magic that others don't. It could also be about how he deals with the reactions of his friends and enemies in Hogwarts when they learn about his new heritage.
Obviously, Harry Potter himself would be a main character as he is the son of Ouranos in this fanfiction. Hermione and Ron would likely still be important characters as his friends.
One possible plot could be Percy's search for his father's lost artifacts. These artifacts hold great power and Percy, as the son of Ouranos, feels a strong pull towards them. Along the way, he has to face rival demigods who also want the artifacts for their own purposes.
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 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.

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.

One possibility is that Percy's new status as the adopted son of Ouranos gives him unique powers. He might be able to control primordial elements like the very essence of the sky and space. For example, he could create storms on a much larger scale than before, drawing power from the origin of the heavens. Another aspect could be his relationship with the other gods. They might view him with a new level of respect or fear, which would change the power dynamics in the demigod world. And Percy would also have to deal with the expectations and responsibilities that come with being related to such a powerful primordial being.
