The magic system could be much more advanced. After 1000 years, Harry might have discovered new spells or ways to use magic that are far beyond what was known in the original story.
In a 'Harry Potter is 1000 years old' fanfiction, the magic system would likely expand greatly. Harry, with his 1000 years of experience, might have delved deep into the essence of magic. He could have found ways to use magic without wands, or even use magic to manipulate time and space in ways not seen before. The original magic system was based on certain rules and limitations, but with Harry's age and knowledge, those rules could be bent or broken. He could also have introduced new forms of magical creatures or elements into the magic system that are unique to his long - lived existence.
It would change the magic system a great deal. In the normal Harry Potter world, magic is somewhat European - centric. However, if Harry is the son of Set, the magic system might blend Egyptian mythology with the existing wizarding world magic. There could be new forms of divination based on Egyptian methods, like reading the movements of the Nile's waters or the behavior of sacred animals. Magic related to death and the afterlife could also be different, perhaps more in line with the Egyptian beliefs about the journey to the underworld.
The magic system could be expanded to include Alicorn - specific magic. For instance, Alicorns might have the ability to perform a type of magic that is related to nature and purity, which is different from the spells that wizards usually cast. This could introduce new spells or potions in the story.
If Harry was a metamorphmagus in fanfiction, it would change the story significantly. For one, his appearance - changing ability could help him avoid detection. For instance, when he's on the run from Voldemort, he could change his looks completely. Also, his relationships might be different. He could use his power to impress or intimidate others. Maybe he'd use it to blend in with different groups at Hogwarts to learn more secrets.
It would change the focus. Instead of just following the main plot of fighting Voldemort, there would be more emphasis on preparation. For example, Harry might spend more time learning about how to protect Hogwarts from all - out destruction rather than just facing Voldemort directly.
If trained by Orochimaru, Harry's magic could change in several ways. Firstly, he might develop a more aggressive and offensive style of magic, as Orochimaru is often focused on power and combat. Secondly, he could start using magic in a more self - serving way, rather than for the good of others as he was taught at Hogwarts. And finally, his connection with magical creatures might change, especially if Orochimaru introduced him to some of the more dangerous and exotic creatures in his world. Harry's magic would no longer be the pure and somewhat naive magic he had before, but a more complex and potentially dangerous form of magic.
If Harry gives up magic, he'd likely move into the Muggle world. This would open up new storylines. He could start a new career in the Muggle world, perhaps in education or some other field. His friends from the wizarding world might visit him secretly, and there could be a whole new set of adventures based on the clash of the two worlds, like how he hides his magical past from Muggles and deals with the occasional magical emergency that still manages to find him.
Well, an apocalypse in Harry Potter fanfiction can change the magic system in multiple ways. Firstly, the availability of magical resources might change. For example, if there are no more potion ingredients growing in the wild, wizards have to find alternatives or create synthetic ones. Secondly, the way magic is taught and learned could be different. There might be a more urgent need for self - taught magic as Hogwarts could be in ruins. And finally, the very nature of some spells could be altered. Dark magic might become more prevalent and the boundaries between dark and light magic could become blurred as everyone is just trying to survive.
Well, for one, his status as the son of two founders would give him a different standing in the wizarding world. He might be more respected or feared right from the start.
Her magic might become darker. Since she is in the realm of Hades, associated with death and the afterlife, her spells could take on a more somber tone. For example, her Patronus, which is usually a positive form of magic, could transform into something more related to the underworld, like a spectral dog with a smoky appearance.
His relationships would also change. Some friends might distance themselves because they are so immersed in the magical world. Others might stay by his side, and together they'd explore a new kind of adventure, one without magic but full of human emotions and real - world challenges.
