Well, her magic could be more closely tied to the moon phases and the cycles of nature. Maybe during a full moon, her powers are at their peak. And she might be able to draw power from natural sources like rivers and forests in a way that normal wizards can't. Additionally, she could have a form of magic that allows her to enter the realm of dreams or the spirit world, which is something that is not part of the regular Hogwarts curriculum. This would set her apart as a very unique witch with a different kind of magic.
Her powers would likely be more centered around charm and love. Regular wizards mainly focus on spells like Transfiguration, Potions, and Defense Against the Dark Arts. But she, as the daughter of Aphrodite, could have the power to influence people's emotions. For example, she could make someone feel love or attraction towards her or others just by a glance or a thought. This is very different from the usual magic that wizards use.
Well, Harry Potter is mainly known for his proficiency in spells like Expelliarmus and his ability to face Voldemort directly. The fem Harry Potter as the daughter of Persephone would have very different abilities. She might have the power to control plants, so she could make vines grow and entangle enemies, which is quite different from Harry's more combat - oriented spells. Also, she could have an affinity for the underworld, perhaps being able to communicate with the spirits of the dead or even traverse the boundaries between the living and the dead world, something Harry has no such ability to do.
Harry might have an easier time with spells related to transformation. Just as Poseidon can change the form of water, Harry could be more adept at transfiguration spells. He could also have a natural ability to breathe underwater and perform magic while submerged, which would be a huge advantage in certain situations. This would open up new possibilities for him in both the wizarding world and any underwater adventures he might have.
She would be much more aggressive. While Harry was brave and sometimes impulsive, her aggression would come from her Ares heritage. She might be quicker to use force rather than diplomacy or cleverness like Harry often did.
Her personality might be different too. The chaos within her could make her more impulsive and free - spirited compared to Harry's more cautious and sometimes self - doubting nature. This could lead to her making different decisions in similar situations. For example, when faced with a dangerous magical creature, instead of trying to find a strategic way out like Harry, she might try to use her chaotic powers to directly confront it.
His magic would likely be more water - based. He might be able to conjure water - made weapons or shields more easily. For example, he could create a spear made of enchanted water that can pierce through dark magic defenses.
The magic would be different in that it would have a more ancient and primal feel. Since Alduin is an ancient and powerful entity, Harry's magic would be influenced by that. It wouldn't be limited to the rules and regulations of the wizarding world. He could potentially have the ability to transform into something more dragon - like, or at least gain some of the physical attributes of a dragon. His magic would be a blend of his own wizarding heritage and Alduin's otherworldly power, creating a completely new and unique form of magic that is both terrifying and awe - inspiring.
The tone can also be different. While the original Harry Potter series has a certain charm and tone that is aimed at a wide audience, including children, fanfiction can be more targeted towards older fans. It might explore darker themes or more complex relationships between characters. Also, the fanfiction may not be bound by the same level of consistency as the official series, allowing for more creative and sometimes wild interpretations.
The magic in the original Harry Potter books is mainly focused on spells and potions that are taught at Hogwarts. However, in fanfiction about ritual magic, it can draw from a wider range of sources. It might incorporate ancient magic from different cultures or lost spells. For instance, a fanfic could have a ritual magic that combines Celtic and Egyptian magical elements, which is something not seen in the original books.
Nature magic often focuses on the elements of nature like plants, animals, and the environment. In contrast, other magics might deal more with spells for personal gain or combat. For example, while transfiguration is about changing the form of an object, nature magic in fanfic could be about making a flower bloom instantly.
