Another possibility in fanfiction is that there is a hidden magical organization or society that both Harry and Merlin were part of, but at different times. This organization could have some sort of family - like structure or a bond that connects all its members across time. So, through this connection, Harry and Merlin are related in the context of the fanfiction.
In some fanfictions, Harry could be related to Merlin through a magical bloodline. Maybe Merlin's magic has been passed down through generations and somehow intertwined with Harry's family tree, like a distant ancestor connection.
Well, it depends on the specific fanfiction. Some fanfiction authors might create a really elaborate backstory where Harry Potter is somehow related to Merlin as an heir. They could base it on things like similar magical abilities, a prophetic connection, or a hidden bloodline. However, not all fanfictions follow this concept. There are many different takes on Harry's story in the fanfiction world, and this is just one of the more imaginative ones.
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.
Popularity of Merlin as Harry Potter fanfiction is a bit of a mixed bag. On some fanfiction websites, there are a decent number of stories that fall into this category. But in the grand scheme of things, it doesn't have the same level of popularity as, say, a typical Harry Potter fanfiction that stays true to the original series' characters and settings. It attracts those who are interested in exploring the crossovers between two magical universes, but it's not as widespread as other forms of Harry Potter - related fan works. There are probably fewer authors writing this type of fanfiction compared to more common Harry Potter fanfiction themes.
In Harry Potter fanfiction, Merlin can be depicted in many ways. Sometimes he's a benevolent figure, guiding the protagonists from the shadows. Other times, he might be a more complex character with his own motives and secrets. He could be presented as the originator of certain spells or magical techniques that are either lost or only partially understood in the main Harry Potter story. And his appearance might be described as a majestic figure draped in robes and surrounded by an aura of ancient magic.
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.
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.
Merlin could use his magic to show Harry visions of a better future. By giving him hope, Harry might change his mind. For example, Merlin could show Harry how his actions in the future would lead to great good.
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 might start by teaching Harry the basics of magic from a different perspective. Maybe he would show Harry how to draw magic from the very essence of nature. For example, instead of using a wand in the traditional way, he could teach Harry to use his hands and the energy around him.
Maybe it could be considered so because of the magic theme. Merlin is well - known for his magic, and in 'Harry Potter', magic is everywhere. The idea of a powerful wizard guiding the fate of others, like Dumbledore in 'Harry Potter' could be seen as similar to Merlin's role in his stories. But this is a very loose connection.
