His magic might enhance the power of the Lord of Light. For example, his spells could make the fires associated with the Lord of Light burn brighter or last longer. His magic could also be used to focus the power of the Lord of Light in a more precise way, like when using a spell to direct a beam of the Lord of Light's energy.
Harry Potter's magic and the Lord of Light's power in Westeros would interact in a complex manner. Harry's magic comes from within himself and his training at Hogwarts. The Lord of Light's power is more about the will of the god and the faith of the followers. If Harry were in Westeros, he might find that his spells can be augmented by the Lord of Light's power. For example, his levitation charm could be made more powerful when he channels the Lord of Light's energy. On the other hand, the Lord of Light's power could be harnessed in a more controlled way with Harry's knowledge of magic. He could create new spells or incantations that are a blend of his own magic and the power of the Lord of Light, which could change the power dynamics in Westeros.
They might interact with Jon Snow. Harry could see a kindred spirit in Jon, both being outsiders in some ways. Kreacher might be initially distrustful but would come around. With Daenerys, Harry could be in awe of her dragons, and Kreacher might be cautious. They would also have different reactions to Tyrion. Harry might see his intelligence, and Kreacher might be a bit wary of his Lannister name.
Well, in a fanfic, the magic of Harry Potter is more structured with spells and potions. In Lord of the Rings, magic is more mysterious and often tied to nature and the power of the Ainur. So perhaps the wizards in Harry Potter could try to study the magic of Middle - earth, like Gandalf's ability to create light. They might find it difficult as it doesn't follow the same rules as their own magic.
In a fanfiction scenario where Harry Potter is in Westeros with the Lord of Light's influence, he would likely face a lot of challenges. The political intrigue in Westeros is very different from the wizarding world. However, his skills in magic could give him an edge. The Lord of Light's prophecies might guide him in a way similar to how the prophecies in the Harry Potter series did. He might find himself in the middle of the wars in Westeros, using his magic to turn the tide. For example, he could use the Imperio curse in a more 'ethical' way to control those who are causing chaos and harm.
There could also be a more complex interaction. Medusa's power might be based on a different type of magic than what is commonly known in the wizarding world of Harry Potter. When Harry tries to understand her magic, he discovers new aspects of magic that he can incorporate into his own spell - casting. This could lead to the development of new spells that combine the principles of both his magic and Medusa's power.
Kakashi's jutsu like the Chidori, which is a powerful lightning - based attack, might interact strangely with the magic in the Harry Potter world. For example, it could disrupt spells if used in close proximity. On the other hand, Harry's magic could potentially be used to enhance Kakashi's jutsu, like using a spell to increase the speed or power of the Chidori.
The magic of Aphrodite could interact with the protective spells in Hogwarts. Maybe her love - based magic could make the protective spells stronger by creating a positive emotional bond between the castle and its inhabitants. On the other hand, if her magic goes out of control, it could weaken the spells as the strong emotions she brings might disrupt the delicate balance of the existing magic.
The magic in Harry Potter is more rule - based and has specific spells and incantations. In contrast, the magic in Elijah Mikaelson's world is more instinctual and related to their vampire nature. In a fanfiction, they could interact in a way that the powerful spells of Harry Potter's world could be used to either contain or enhance the abilities of the vampires. For example, a spell like 'Impedimenta' could be used to slow down a vampire's super - speed.
His magic might be more aggressive. Growing up with the Dark Lord, he would be taught to use magic for more forceful and often cruel means. For instance, instead of using a simple Stunning Spell like in the original, he could be using more dangerous and unforgivable - like spells without hesitation.
Harry's magic would likely be both a source of wonder and suspicion in Spartan culture. His ability to conjure things out of thin air might be seen as a gift from the gods by some, while others would be more cautious. For example, his magic could be used to help in the Spartan's agricultural efforts, like making crops grow faster, but this might also disrupt their traditional ways of farming.
The magic in Harry Potter is more about spells and incantations, while Hope's magic has a more primal and ancestral feel. In a fanfiction, they could complement each other. For example, Harry's Patronus charm could be enhanced by Hope's connection to the spirit world. Or Hope's ability to draw power from the elements could be combined with Harry's knowledge of transfiguration to create new forms of magic.
