His character would be much more complex. Instead of just being the brave Gryffindor hero, he would have an inner conflict between the light and dark. His connection to Artemis would make him more in tune with nature and the moon, so he might be more solitary at times, like Artemis. His Hades side could make him more brooding and mysterious. He may also be less trusting of others as he has to keep his true identity a secret from most in the wizarding world.
Well, Harry would be a very different character indeed. His courage would still be there, but it would be tempered with a wariness from his Hades heritage. He would be more attuned to the cycles of nature and the moon because of Artemis. This could affect his mood and his magic. For example, he might be more powerful during a full moon. His relationship with Dumbledore would also be different. Dumbledore would have to approach Harry with more caution as he is now the son of two very powerful and different entities. Harry would also have to deal with the jealousy and fear of others in the wizarding world. His appearance might even change slightly, with a more otherworldly look from his divine parents, and this could further isolate him as he tries to fit in while being so different.
He would be much more aggressive in combat. With Ares as his father, he'd have a natural warrior instinct. He might not shy away from a fight like the original Harry. For example, he could be the first to charge into a battle against Death Eaters.
Percy could have the power to manipulate the coldness that is often associated with the Underworld. He could freeze his opponents or create ice - like structures out of the cold energy. This would be different from his water - based powers in the normal story. Also, he may have a stronger connection to the gems and precious metals that are found in the Underworld, being able to sense them and even use them in some way for his benefit.
His magical training would likely be more nature - oriented due to Artemis' influence. He might spend more time outdoors, learning magic that is related to the elements, like controlling the wind or water in ways that are connected to the moon's power. For example, he could learn spells that are more effective during a full moon. With Athena's influence, his training in spells would be more strategic. He wouldn't just learn how to cast a spell, but also when and where to use it for maximum effect, like a military strategist.
Harry would be a different character in this fanfiction. He'd have a different upbringing, being the son of James Bond. This would give him a different perspective on the world. He would be more attuned to the Muggle world's espionage and intrigue, which would affect his relationships at Hogwarts. He might be a bit of an outsider among his peers, as his experiences and knowledge would be more diverse. He could be more of a loner, but also more self - reliant. His decision - making would be influenced by Bond's rational and calculated approach. For example, when facing a dark wizard, he might analyze the situation more like a spy, looking for weaknesses and planning several steps ahead, rather than just reacting impulsively with magic as the original Harry might do in some cases.
He would be more in tune with nature. Since Dionysus is associated with nature, Harry might have an instinctive understanding of plants and animals that normal wizards don't. For example, he could communicate with magical beasts on a deeper level.
Well, it could start with Harry having strange dreams or visions about his real parents. As he investigates, he uncovers the truth. His story could then revolve around him trying to unite the two very different worlds of his parents. He may face challenges from both the Greek gods and the wizards. For instance, Zeus might see him as a potential threat as the son of Hades and try to stop him. In the wizarding world, the Ministry of Magic might fear his new - found powers. Harry would need to learn to control his powers from both Artemis and Hades. He could have a special weapon or tool given to him by his parents, like a bow from Artemis that can shoot magical arrows or a key to the underworld from Hades that gives him access to certain dark magics which he must use for good.
In terms of his relationships, he would have a different family dynamic. He would be more connected to the Black family legacy. This could make him more empathetic towards Slytherins who might also be related to the Blacks. His views on pure - blood and half - blood issues could be more complex. He might also be more likely to explore the darker side of magic in a more controlled way, as he tries to understand his father's past, which would be a significant departure from his original character development.
He might initially be met with suspicion by the Hogwarts staff. Dumbledore, being the wise headmaster, would likely be intrigued but cautious. The demigod could have a complex relationship with Harry. They could be both friends and rivals, as they both have unique powers. Hermione might be fascinated by his demigod heritage and want to study it, while Ron might be a bit more wary.
His magical abilities would likely be more nature - oriented. With Artemis being a goddess of the hunt, he might be able to communicate with magical creatures in the forest better than other wizards. And from Hera, he could have the ability to manipulate magical energy in a more powerful and efficient way. For example, his spells could be stronger and last longer.
It would probably be full of interesting twists. Harry might have some dark powers from Hades, like the ability to control the dead. His character could be more brooding and less naive compared to the original.
