His magical abilities could be different in many ways. Since James was a strong wizard, and Remus was a werewolf with his own unique magical condition, Harry might have a more complex magic. He could potentially have an easier time with transfiguration, given James' skills in that area. And perhaps some connection to the more primal or lunar - influenced magic due to Remus. For example, he might have an enhanced ability to sense danger during the full moon.
If Harry were James and Remus' son in the fanfiction, his magical abilities would likely be a blend. He might inherit James' natural aptitude for charms and flying, which were some of James' strong suits. From Remus, he could get a more intuitive understanding of the darker aspects of magic, like the magic associated with werewolves. His magic could also be more in tune with nature, given Remus' connection to the moon and the wild through his lycanthropy.
His Hogwarts experience would likely be very different. He might be more popular right from the start, given the fame of both James and Sirius. The teachers might also have different expectations of him. For example, McGonagall might be more lenient as she had a soft spot for James. And he could have a natural talent for Quidditch, inheriting James' skills. He might also be more involved in secretive activities, like Sirius was, and get into more trouble with Filch.
His magical abilities would likely be more nature - oriented. With Artemis being a goddess of the hunt, he might be able to communicate with magical creatures in the forest better than other wizards. And from Hera, he could have the ability to manipulate magical energy in a more powerful and efficient way. For example, his spells could be stronger and last longer.
He'd probably be more confident. With Sirius and Remus as his guardians, he'd have two strong male figures who believe in him wholeheartedly. Sirius's boldness and Remus's wisdom would rub off on him. He might be less hesitant in taking risks and more assertive in his actions.
His magical abilities could develop in a more gradual and mysterious way. He might have dormant powers that only surface when he's in great danger or when he has a strong emotional connection to something. For example, he could discover he has the ability to communicate with magical creatures on a deeper level, like Harry could with snakes, but this power might not show up until he's older and has had certain experiences. Also, his magic could be influenced by the strong bond between Harry and Sirius, which could give him an edge in defensive magic.
In this fanfiction, their different magical abilities could be explored in a friendly competition. They could have a series of magical challenges where Harry uses his Gryffindor - like courage and quick thinking, and Viktor uses his Durmstrang training in elemental magic. Through this competition, they not only show off their abilities but also learn from and respect each other's skills.
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.
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.
His magical education would likely be more hands - on. Dresden is often in the thick of things in his world, so Harry Potter would probably get real - world experience much earlier. Instead of just learning from textbooks in a classroom, he'd be out there facing actual magical threats and learning on the job.
Harry would be a different character in this fanfiction. He'd have a different upbringing, being the son of James Bond. This would give him a different perspective on the world. He would be more attuned to the Muggle world's espionage and intrigue, which would affect his relationships at Hogwarts. He might be a bit of an outsider among his peers, as his experiences and knowledge would be more diverse. He could be more of a loner, but also more self - reliant. His decision - making would be influenced by Bond's rational and calculated approach. For example, when facing a dark wizard, he might analyze the situation more like a spy, looking for weaknesses and planning several steps ahead, rather than just reacting impulsively with magic as the original Harry might do in some cases.
His Hogwarts experience would be very different. Firstly, he would likely enter Hogwarts with a much higher level of magical knowledge. James and Sirius could have taught him a great deal before he started school. So, he might be ahead in classes like Transfiguration and Defense Against the Dark Arts. Secondly, his social status would be different. Everyone would know he is the son of James Potter, a popular and talented wizard. This could lead to him being more of a center of attention, and he might have a different group of friends. Instead of Ron and Hermione at first, he could befriend students from more well - known wizarding families.
