For Harry, he might be shown with enhanced spell - casting speed and accuracy. His Patronus could be stronger or have new abilities. As for Merlin, his traditional powers may be toned down. Maybe his ability to foresee the future is not as accurate as it was originally depicted, making Harry seem more powerful in comparison.
As for Merlin, in this fanfiction, he is likely to be portrayed as less powerful than we usually think. His image might be adjusted to highlight Harry's strength. Maybe Merlin is shown as having some limitations in his magic that Harry doesn't have. However, it could also be that the fanfiction shows a different aspect of Merlin, like he might be more focused on other non - combat - related magic while Harry is stronger in direct magical combat.
In this fanfiction, it could be that Harry's power stems from his experiences. He has faced numerous dark wizards and challenges, which have forced him to grow stronger. Merlin, on the other hand, might not have had such intense and varied experiences. So, through his trials, Harry has developed powers that surpass Merlin's.
Magic knowledge. Harry has a lot of knowledge from Hogwarts, which could be more comprehensive than what Merlin had. So in fanfiction, this knowledge could be used to show he's more powerful.
Well, in some fanfictions, Harry Potter might be seen as more powerful than Merlin because Harry has faced and defeated Voldemort. That's a huge accomplishment. Merlin, while very powerful in his own right, didn't have to deal with a dark wizard as complex and powerful as Voldemort. Harry's ability to survive the Killing Curse as a baby also gives him a sort of 'chosen one' status that could be seen as making him more powerful.
Merlin might use his magic skills to help Harry. For example, he could use his knowledge of ancient spells to protect Harry from dark magic. Maybe he helps Harry in battles by creating magical shields or illusions to deceive the enemies.
The fanfiction might show a more powerful Hogwarts. With Harry having Merlin - like strength, he could introduce new magical teachings and practices. For instance, he could teach students how to use magic in ways not previously known at Hogwarts, like Merlin - style spellcasting that is more powerful and efficient.
Well, in many such fanfictions, Merlin might use his magic skills. He could draw on ancient spells and his deep knowledge of magic. Maybe he starts by gathering special materials like a rare wood from an enchanted forest. Then, with precise incantations and his powerful magic, he shapes the wood into the form of a staff, imbuing it with magical properties.
Merlin could influence Harry to be more empathetic. Merlin, having witnessed the rise and fall of many, would understand the importance of seeing things from different perspectives. So Harry, under Merlin's tutelage, may start to look at the motives of his enemies and not just see them as pure evil. This could make Harry a more complex and well - rounded character, as he tries to find solutions that don't always involve combat but rather understanding and negotiation.
In the fanfiction, Merlin might use his ancient and powerful magic to source rare materials for Harry's wand. He could search for a special type of wood, perhaps from a magically protected tree. And for the core, he might look for a unique magical essence like the hair of a mythical creature. He would then combine these elements with his incantations and spells to shape the wand into a perfect tool for Harry.
Merlin could help in Harry Potter fanfiction by being a sort of spiritual guide. Since he is a very well - known and powerful wizard in wizarding lore, his name and deeds could inspire the characters. He might appear in dreams or visions to Harry, Hermione, or Ron, guiding them on their quests, like how to find a hidden Horcrux or the true nature of Voldemort's power.
