In this fanfiction scenario, Harry's magical abilities would be nurtured in a way that combines the best of what each founder had to offer. He would grow up with a strong connection to the magic of Hogwarts itself. His development would not be just about learning spells from textbooks but experiencing magic in its purest form. The founders would teach him how to tap into the raw power of magic, not just the practical applications. This could lead to him having unique magical manifestations, like being able to sense the history and magic within the castle walls and use that energy for his spells. His abilities would be a blend of the ancient magic of the founders and his own natural talent, making him an extremely formidable wizard.
Harry's magical abilities would develop in a very different manner. Since he is raised by the founders, they would likely train him from a young age. They might focus on the fundamentals of magic in a more in - depth way compared to the modern Hogwarts curriculum. He could have an enhanced ability to communicate with magical creatures as the founders had a closer relationship with them. His spell - casting would be more precise and powerful, perhaps even having the ability to use magic that has been lost over time due to the founders' direct guidance.
His magical abilities would likely be developed in a more archaic and powerful way. The founders had different areas of expertise, so Harry could inherit a wide range of skills. Maybe he'd be a master of defensive magic like Salazar Slytherin was known for some aspects of it, and also be proficient in charms like Helga Hufflepuff was with her kind magic.
His magical abilities would likely develop at a much faster rate. The founders are extremely powerful and knowledgeable. They could guide Harry to discover and master magic that most wizards his age wouldn't even know exists.
His magical abilities might develop with a greater emphasis on intellectual magic. Since Rowena Ravenclaw is associated with knowledge and wisdom, Harry could be more inclined towards spells that require deep understanding and study. For example, he might master complex transfiguration spells earlier because Ravenclaw would encourage him to study the theory behind them thoroughly.
His magical abilities might be influenced by the Norse magic system. He could have a more primal and elemental approach to magic, perhaps being able to control natural forces like thunder (associated with Thor) or ice (linked to some Norse entities).
Harry could develop a more unique style of magic. His grandfather might have his own way of doing magic, and Harry would learn from that. For example, his grandfather could be more in tune with nature magic, and Harry would then incorporate that into his spell - casting, making his magic more diverse and less reliant on the traditional Hogwarts curriculum.
His magical abilities could develop in a very unorthodox way. In Wonderland, the laws of nature are so different. He might learn to use magic in ways that are more about manipulating the chaotic environment rather than the traditional spell - casting in the wizarding world. For instance, he could use magic to navigate through the constantly changing landscapes of Wonderland.
If raised by Newt, Harry's ability to sense the emotions and needs of magical creatures would be enhanced. This is because Newt has a great understanding of these aspects. Harry might also develop unique magical abilities that are specific to interacting with the habitats of magical beasts, like being able to create or modify suitable environments for them with magic.
If Harry meets the founders in fanfiction, the story might develop in a way that Harry is given a mission by the founders. This mission could be related to saving Hogwarts from an ancient threat that only he, with the help of the founders' knowledge, can defeat. Along the way, he would interact with different historical figures and magical creatures that the founders introduce him to.
He'd likely be more humble. Elves are not boastful, and growing up with them would instill that in Harry. He might be less likely to seek fame or glory like in the original story.
Harry might develop a more confident and assertive personality. Growing up with Dorea, he would be exposed to the power and influence of the Black family. This could make him more self - assured and not as hesitant as he was in the original story. He may also be more politically aware, knowing how the different wizarding families interact and jockey for power. For instance, he would understand the implications of being associated with certain families and how to use those connections to his advantage while still maintaining his moral compass.
Harry would probably be more wild and less bound by wizarding society's norms. Dragons don't follow human rules, and being raised by them would make Harry question and break free from some of the traditional wizarding ways. He might be more instinctive in his actions and decisions, just like how dragons act on their instincts.
