Well, some fanfics blend the two worlds by making 5sos be related to some wizarding families. So, they already have a connection to the wizarding world without really knowing it. Then, as they discover their heritage, they get involved in the Harry Potter storylines. It could be that one of the 5sos members has a long - lost wizard relative and that's how they are drawn into the magical universe. This way, the two worlds are intertwined in a more family - based way.
The blend often occurs at a character level too. Characters from both series might form alliances or rivalries. A friendship between Legolas and Hermione could develop, with each sharing their knowledge of their respective worlds. Or perhaps Snape and Saruman could be pitted against each other, their cunning and knowledge of dark magic making for a great showdown. These character interactions help to bring the two very different worlds of 'Lotr' and 'Harry Potter' together in the fanfiction.
The worlds might blend through the use of shared magical elements. For instance, both have magical creatures. The gargoyles' ability to turn to stone during the day and come alive at night could be related to some form of Transfiguration magic in the Harry Potter world.
It can blend the two worlds by having the droids use their technological features in the wizarding world. For example, a droid's built - in map system could be used to navigate the complex corridors of Hogwarts. The droids could also introduce new concepts like energy sources that wizards might be able to adapt for their magic.
In this fanfiction, the blending might occur when a group of wizards decides to study Muggle technology to gain an edge in the fight against Voldemort. They stumble upon the concept of the atomic bomb. Harry Potter then gets involved as he tries to prevent the wizards from misusing this knowledge. The story could show how the different cultures and power systems of the wizarding and Muggle worlds collide and interact around the idea of the atomic bomb.
It blends the two worlds by using the familiar characters from Harry Potter and putting them in the irreverent and often chaotic situations of Cards Against Humanity. The characters' personalities play a big role. Harry, for instance, might be a bit more reserved in the game compared to Ron's more carefree approach.
In fanfiction, the two universes blend in multiple ways. The characters from Harry Potter can be put into Creepypasta - like situations. For instance, Harry might find himself in a situation where he has to face a entity that is not from the wizarding world but from a Creepypasta realm and has to use his magic in a new and untested way to survive. Also, the magic in Harry Potter can be warped to fit the spooky nature of Creepypasta. Spells could have unexpected and disturbing side - effects that are more in line with Creepypasta. The creatures in Harry Potter can also be made more menacing by borrowing elements from Creepypasta. For example, a Hippogriff could be made to look more like a nightmarish beast with Creepypasta - inspired features.
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.
A 'Harry Potter Cheshire Cat' fanfic could blend the two universes by having the Cheshire Cat enter the wizarding world through a magical portal. Once in the world of Harry Potter, it could interact with the characters using its unique abilities. For example, it could use its disappearing act to steal food from the Hogwarts' kitchen without being noticed by the house - elves.
The settings can also be blended. Maybe there could be a part of the Star Wars galaxy that has a Hogwarts - like school for Force - sensitive individuals. Padme could visit this place and meet Harry Potter there. This would bring elements of both universes together in a physical and cultural sense, making for an interesting fanfic.
To blend the two cultures well in a Harry Potter kimono fanfic, the author could focus on the values of both cultures. In the Harry Potter world, friendship and courage are important, and in Japanese culture, respect and harmony are key. So, a story could be about a group of friends who come together to create a special kimono for a Hogwarts event. They have to overcome differences in their understanding of magic and culture. Along the way, they learn about each other's values and use them to make the kimono not just a piece of clothing, but a symbol of unity between the two cultures. They might use elements like Japanese calligraphy on the kimono to represent spells or Hogwarts houses.
