The blending can occur in terms of power systems. The Nephalem has its own set of powers, which could be related to physical strength, elemental control, etc. In the Harry Potter world, these powers could be seen as a new form of magic that is not well - understood. The wizards might try to study the Nephalem to learn from their powers. In DxD, the Nephalem's powers could be on par with or even exceed those of some of the devils and angels. This could lead to new power struggles and alliances. For example, a Nephalem with the power of flight could be both a threat and an asset in the DxD world where flight is also a significant ability among the supernatural beings.
One way to blend them is through the plot. Suppose there is a powerful dark force that is a threat to all three worlds. The heroes from Harry Potter, the Nephalem, and the characters from DxD would have to come together to fight it. The Nephalem could use their skills from their own world, like demon - slaying abilities, in the magical world of Harry Potter. In DxD, they could use the magical knowledge from Harry Potter to outwit their enemies. And the different cultures and power hierarchies from each world would create a rich tapestry for the fanfiction.
Well, it might feature a story where the magic systems of Harry Potter and DxD are merged with the Nephalem's powers. The Nephalem could be a sort of catalyst for change. In the Harry Potter part, they could introduce new spells or ways of using magic that are inspired by their own powers. In DxD, they could add a new layer of power dynamics. For instance, if the Nephalem has some sort of shape - shifting ability like some Diablo characters, it could be used to deceive both the devils and angels in DxD, leading to some very interesting plot twists.
In a fanfiction, the blending could occur in a more dangerous situation. Let's say there is a rift between the two worlds and the magic is getting mixed up in a chaotic way. The characters have to figure out how to control this new, combined magic. They might find that some spells from Harry Potter work differently when combined with the energy of the devils in Highschool DxD. For example, the Killing Curse might be affected by the demonic energy and instead of just killing, it could turn a target into a half - devil. This would force the characters to understand both magic systems deeply and find a way to separate or control the combined magic before it causes more harm.
To blend these elements effectively, start by choosing a central theme. For example, a struggle for power. In Harry Potter, there is the fight against Voldemort for control of the wizarding world. In Game of Thrones, it's the battle for the Iron Throne. You can then introduce the concept of lordship from Game of Thrones into the Harry Potter world or vice versa. Maybe the Ministry of Magic is re - structured to be more like the lordship system in Westeros, with different magical families having more control over specific regions.
In 'Harry Potter Incubus Yaoi' fanfiction, it often blends by inserting the concept of incubus (a type of demon) into the Harry Potter universe. The yaoi aspect might come in through male - male relationships. For example, an incubus character could be introduced into Hogwarts and form a relationship with a male character from the original series, thus combining the magical world of Harry Potter with the otherworldly and often sexualized nature of incubus and the male - male relationship dynamic of yaoi.
Well, in these fanfictions, the magical creatures in Harry Potter can be compared or even interact with Pokémon. The Hippogriff, for example, could be seen as a more magical version of a flying Pokémon. And the concept of magical potions could be used to create something that affects Pokémon in different ways, like a potion that makes a Pokémon stronger or more docile. The Portkey in Harry Potter could also be used to transport trainers and their Pokémon to different magical locations in the wizarding world.
In fanfic, they can blend in various ways. For example, the magic systems can be combined. The runes from 'Mortal Instruments' might be used alongside spells from 'Harry Potter'.
One way is through the use of magical artifacts. In a 'Harry Potter science fanfiction', a time - turner could be studied from a scientific point of view. Scientists (wizard scientists) might try to figure out the physics behind traveling through time, looking at concepts like relativity and how magic circumvents them.
Authors need to first understand the core elements of both universes. For Harry Potter, it's the magic, Hogwarts, and the fight against Voldemort. In KHR, it's the Mafia families and the growth of Tsuna. Then, they can start by introducing characters from one universe into the other in a believable way. For instance, if Harry were to enter the KHR world, how would he adapt to the different rules and powers there?
The themes blend by pitting the light - hearted and somewhat familiar magic of Harry Potter against the mind - bending, incomprehensible horror of Cthulhu. For instance, the concept of good vs. evil in Harry Potter takes on a new dimension when faced with the amorality of Cthulhu - like beings. The wizards' sense of order and their magical laws are challenged when these chaotic and eldritch forces enter their world.
Well, in some fanfics, the honor code of the Yautja might blend with the Gryffindor's sense of bravery. A Yautja might respect a Gryffindor who shows great courage in the face of danger, just as they respect worthy opponents in their own culture.
