A Veela girlfriend would likely change Harry's social life a great deal. In the wizarding world, Veelas are known for their beauty and allure. Harry would be constantly in the spotlight because of her. Also, her Veela nature might give her certain powers or instincts that could assist Harry in his fight against dark forces. For instance, she might have a natural ability to detect dark magic, which would be a huge advantage for Harry. Moreover, their relationship would add an emotional depth to Harry's character, as he would have to deal with the strong emotions that come with loving a Veela.
She could make him more aware of the Muggle world. Harry has grown up mostly in the wizarding world, and having a Muggle girlfriend would expose him to different ways of thinking, like Muggle technology and their social customs.
His personality might become more alluring like the Veela. He could be more confident in his appearance and charm, which is different from the somewhat self - doubting Harry in the original story. He may also be more in tune with his emotions as Veela are known for their passionate nature.
For Draco, being Harry's mate would likely soften his edges. His Veela nature might make him more nurturing towards Harry. He would probably become less focused on pure - blood supremacy and more concerned with protecting and loving Harry. Harry, in turn, would become more understanding of Draco. His view of Slytherins might change completely. He would be more patient and less quick to judge, as he now has a deep connection with a former Slytherin.
When Harry is raised by Veela in fanfiction, it transforms the story on many levels. His identity would be shaped by Veela heritage. He would likely be more in tune with his non - human side, if there is such a thing in this context. His magic would be a blend of wizarding magic and Veela magic. This could mean he has new spells or ways of using magic at his disposal. His relationships would also be redefined. He might be seen as an outlier by some in the wizarding community because of his Veela - raised background. His understanding of good and evil could also be different. Since Veela have their own code of conduct, Harry might approach moral dilemmas with a different mindset compared to the Harry in the original series.
His living conditions would change drastically. Instead of living in the wizarding world, he'd be in palaces. He'd have servants and all the luxuries that come with royalty. His friends at Hogwarts would be replaced by new acquaintances in the royal circle. He'd have to adapt to a very different set of rules and expectations.
Well, it would change a great deal. For one, he might get better grades in Potions as Snape would be more likely to give him extra help. Also, he might be more protected from the likes of Draco Malfoy and his gang, since Snape would not tolerate any bullying towards his adopted son. Harry could also have access to Snape's private library, which would expand his knowledge of magic far beyond what he could learn in the regular Hogwarts curriculum.
His magical education could be enhanced. Sirius has a wealth of knowledge about the wizarding world, especially about things that are not taught in Hogwarts. He could introduce Harry to different magical creatures in a more hands - on way and teach him spells that are not part of the regular curriculum. Harry would also gain more confidence in his magical abilities as Sirius would constantly encourage him.
The story changes a great deal. Harry's identity crisis would be a major part of it. He has to adjust to being a female Veela, which means dealing with different social expectations. At Hogwarts, the professors might treat him differently. Snape, for instance, might be even more begrudging of his new allure. His friends would also need to adapt. Hermione would probably be the one to help him the most, guiding him through the new social situations. His love life, if there was any in the original story, would be completely rewritten. Instead of having crushes on Ginny or Cho, he might find himself pursued by different characters, and he might develop new feelings for someone unexpected.
In this fanfiction, Harry's life at Hogwarts would be full of new discoveries. He could find secret passages that are overgrown with plants but are only visible to him because of his connection to Demeter. His friends might be a bit in awe of his new powers. He'd also have to deal with some jealousy from other students who don't have such unique abilities. And when it comes to Quidditch, he could use his nature powers to his advantage, like creating a gentle breeze to help him fly faster or making the grass on the pitch grow in a way that confounds his opponents.
Harry's relationships might also change. Some students might be in awe of him and want to be his friend just because of his wings. However, others might be jealous. He would also have to deal with the stares and whispers. But overall, his wings could give him a new sense of confidence and independence, allowing him to face his enemies, like Voldemort, with a different kind of courage.
