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 this fanfiction, the settings blend by creating new landscapes. The magical architecture of Hogwarts might be combined with the ancient structures of Assassin's Creed cities. For instance, the towers and battlements of Hogwarts could be used as vantage points for Assassins. The Ministry of Magic building could be located near an Assassin's Creed stronghold. Also, the dark and mysterious places in both settings, like the catacombs in Assassin's Creed and the Chamber of Secrets in Harry Potter, could be connected, perhaps leading to a new and dangerous underworld.
Well, first of all, the wands in Harry Potter could have an interesting interaction with the vampiric powers. A wizard could use a spell from their wand to create a shield against a vampire's attack. And the potions in Harry Potter could be used to either cure someone who is turning into a vampire or to enhance a vampire's abilities in some strange way. The magical creatures in both worlds could also play a role. Thestrals, which are associated with death in Harry Potter, might have some connection to the vampires in Dracula Untold since vampires are undead. The fanfic could explore these connections and create a whole new set of magical rules.
Well, it combines the magical world of Harry Potter with the dark and alluring concept of a vampire king. In these fanfictions, the vampire king can bring a new type of power dynamic. For example, it might change the way magic is perceived or used in the story. The Hogwarts setting is also transformed as the vampire king's presence could disrupt the normal order. It's like adding a spicy new ingredient to an already delicious dish.
Well, magic in Harry Potter is very different from the powers of the Greek gods, but in fanfiction, they can be blended. For instance, the wands in Harry Potter could be seen as similar to the staffs that some Greek gods carry. The spells could be related to the incantations that the gods might use. Maybe a spell like 'Accio' could be seen as a weaker form of a god's power to summon things.
Well, it often blends the two by having characters from one universe enter the other. Like a Supernatural character might end up in the wizarding world through some sort of magical portal or spell gone wrong. Then they have to adapt to the new rules and powers there.
In these fanfictions, they blend by sharing certain characteristics. For example, the loyalty and camaraderie among the characters in both universes are emphasized. In Harry Potter, it's the loyalty among the students of Hogwarts and the Order of Phoenix. In Kancolle, it's the bond between the shipgirls. This common trait can be a basis for the two universes to interact, like the shipgirls and the wizards/witches working together based on mutual trust.
Often, they blend the two worlds through magical elements. For instance, the magic from 'Reborn' might be introduced into the Hogwarts curriculum in some fanfictions. This can create a lot of chaos or new opportunities for the students.
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'.
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.
