Perhaps Percy would have a more strained relationship with the other gods. Since Hera is not the most popular among the gods, those who oppose her might be less inclined to help Percy. He would also likely have a very different relationship with Zeus. With Hera as his mother figure, Zeus might be more watchful and even more distrustful of Percy, fearing that Hera has some ulterior motive in raising him.
One possible plot could be that Hera, being a powerful goddess, would raise Harry in a world that's a blend of the wizarding world and the realm of Greek mythology. Harry might learn magic in a very different way, perhaps with more of a focus on the divine and natural elements that Hera represents. He could also have different relationships with the characters in the wizarding world. For example, his relationship with Dumbledore might be more of a power - struggle as Hera may not want Dumbledore to have too much influence over Harry.
Well, in this fanfiction, perhaps there's some sort of magical interference that makes Percy and Hera fall in love. It could start with Percy accidentally stumbling upon a powerful magic that binds their fates together.

He might face opposition from other gods who don't approve of their union, and he'll have to find a way to win them over.
Well, in this fanfiction, perhaps Percy is adopted by Hera to serve as a bridge between the gods and the demigods. Hera might see his potential to unite both groups and decides to take him under her wing. Percy then has to navigate the complex politics of Olympus while still maintaining his relationships with his demigod friends.
He would probably be more haughty. Hera has a certain air of superiority, and being raised by her might make Percy think he is above others in some ways. He could also be more secretive, as Hera often has her own schemes and Percy might learn to keep things to himself.
One plot idea could be Percy having to team up with Hera to rescue a group of demigods who have been captured by an ancient monster. Hera, despite her usual aloofness, realizes she needs Percy's unique skills.

A great plot could revolve around Percy's role in the power dynamics among the gods. As the son of Hera and Poseidon, he has the potential to shift the balance. Some gods might try to use him as a pawn, while others see him as a threat. Percy would then have to navigate this complex political situation among the gods while also dealing with his own personal growth and the challenges that come with being a demigod.
Well, one possible plot could be that their baby has some sort of unique power. Since Percy is a demigod with special abilities like controlling water, and Hera is a powerful goddess, their child might inherit a blend of powers. Maybe the baby has the power to control the weather, as it combines Percy's elemental connection with Hera's association with the sky. This could lead to all sorts of adventures where the baby has to learn to control its powers while facing threats from other mythological beings who are either jealous or see the baby as a threat to their own power.

He then discovers a long - forgotten secret about the gods that he has to use to save the world, all while trying to keep his relationship with Hera a secret from his fellow demigods who would be horrified at the thought.
