Harry's magic would be a unique blend. With Aphrodite as a parent, his magic could be more attuned to the emotions of others. He might be able to sense the feelings of his opponents in a duel and use that to his advantage. From Ares, his magic would be more physical and forceful. His levitation spells might be able to lift heavier objects more easily, and his transfiguration spells could be quicker and more precise, as if his magic has a more militaristic efficiency.
Since Aphrodite is associated with love and beauty, Harry's magic could have an aesthetic quality. His Patronus might be more beautiful or have an added charm factor. And because of Ares, his defensive magic could be more battle - oriented. Instead of just creating a shield, it could be a shield that also attacks opponents who get too close, reflecting Ares' war - like nature.
His magic could be more intense and have a different flavor. The influence of Aphrodite might make his spells more alluring. For example, a stunning spell could have a sort of charming effect added to it, making the victim more docile. From Ares, his magic could be more aggressive, like his blasting spells could be more powerful and destructive.
His powers would be a blend. He might have superhuman strength like Ares, allowing him to overpower opponents easily. And from Aphrodite, he could have the power of persuasion. So, instead of just using ninjutsu, he could also convince enemies to surrender with his charm.
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.
Canon Percy is mainly influenced by Poseidon, which gives him a certain set of traits like being loyal and having a connection to the sea. But if Percy was the son of Ares and Aphrodite, his personality would be a wild mix. He'd likely be more aggressive like Ares, quick to anger in some situations. However, Aphrodite's influence would also make him more charming and aware of social dynamics. He might be more concerned with appearances and how others perceive him compared to canon Percy.
The magic of Aphrodite could interact with the protective spells in Hogwarts. Maybe her love - based magic could make the protective spells stronger by creating a positive emotional bond between the castle and its inhabitants. On the other hand, if her magic goes out of control, it could weaken the spells as the strong emotions she brings might disrupt the delicate balance of the existing magic.
It could be stronger in certain dark arts. Given his parentage, he might have a natural affinity for curses and hexes that are associated with the dark side. He could learn and perform these spells with greater ease compared to other wizards. However, he might struggle with defensive and positive magic, like healing spells or protective charms.
Well, one aspect of the plot could be that Harry is initially unaware of his true parentage. As he discovers it, he has to deal with the shock and also the expectations that come with being the son of two such powerful Greek deities. He might face challenges from both the wizarding world and the world of Greek mythology. For example, some Greek mythological creatures might be after him, thinking he has special abilities or items due to his heritage.
Harry's magic could be stronger. Dorea's influence and knowledge of magic could have allowed Harry to tap into his magic potential more easily. Maybe he would be able to perform advanced spells earlier. Also, his magic might have a different 'flavor' so to speak. Since Dorea comes from a different magical background than the Dursleys, Harry's magic could be more attuned to the traditional wizarding ways of magic use.
It would be really strange. Harry is known for his wizarding abilities like using a wand and spells. But if he were the son of Ares, he might have some combat - related powers from the Greek god of war. Maybe he could be super strong in physical battles and have a more aggressive approach to fighting dark wizards compared to his usual style in the original series.
His magic could incorporate more elements of Japanese magic. For example, his spells might be more about harmony with nature, like some Japanese magical traditions.
His magic could be more combat - oriented. Jiraiya's ninja background would likely influence Harry to use magic in a more direct and aggressive way in battles, rather than just for defensive or utility purposes like in the original series.
