Writers often blend the two universes' aesthetics by incorporating the dark and gritty atmosphere of 'Darker than Black' into the more superhero - centric 'Worm' world. For example, they might describe the cityscapes in 'Worm' with the same sense of foreboding and mystery as in 'Darker than Black'.
The aesthetics blend quite well. RWBY has its vibrant color - coded characters and unique weapon designs. Transformers Prime has its sleek, mechanical look. In fanfictions, you might see Ruby's red cloak fluttering next to Optimus Prime's red and blue armor, creating a visually appealing contrast.
The sleek, high - tech look of Halo's UNSC and Covenant ships can contrast sharply with the gothic, ornate designs of Warhammer's spacecraft and architecture. In fanfiction, authors might describe how the angular, metallic forms of Halo coexist with the spiky, daemon - influenced aesthetics of Warhammer. For example, a UNSC base on a Warhammer world might look like a strange outlier, or perhaps over time, it starts to adopt some of the local, more flamboyant design elements.
Writers often blend the two universes by creating a common threat. For example, a demon that has ties to both the Supernatural world and the DC universe's magic or technology. They also use character crossovers, like having Dean Winchester meet Clark Kent. This allows for an exchange of ideas and values between the two different worlds.
Writers blend the two universes by incorporating elements of the Naruto power system into the Until Dawn setting. For example, they might introduce chakra into the Until Dawn world. They also blend the characters' personalities. A Naruto character's determination can be combined with an Until Dawn character's survival instincts.
Writers blend the two universes by combining the magic systems. In Game of Thrones, we have magic like the wildfire and the warging ability. In Warcraft, there's arcane magic, druidic magic etc. A fanfic might have a character who can use both the warging ability from Game of Thrones and druidic magic from Warcraft, creating a really unique power combination. They also use the geography. Maybe a fanfic has a portal opening between the Seven Kingdoms and Azeroth, and then characters from both sides start exploring the other world. This allows for a lot of interesting interactions and conflicts.
One way is by creating crossover characters. For example, a character could have the powers of a Jedi from Star Wars and also be a part of the Avengers team. Another way is to use similar story elements like a fight against a powerful and evil force. Writers can also have the heroes from both universes meet in a neutral location, like a new planet or dimension, and team up to face a common threat.
The aesthetics can blend really well. RWBY has a more fantasy - based aesthetic with its magic, different kingdoms, and the design of the Grimm. Black Rock Shooter has a more post - apocalyptic and edgy aesthetic. In fanfiction, this could be combined by having the characters travel between the two worlds. For instance, the RWBY characters might find themselves in Black Rock Shooter's desolate world and be amazed by the strange architecture and the dark atmosphere, while also bringing a bit of their own colorful and more hopeful aesthetic to that world.
Writers can start by researching the lore of both shows thoroughly. They need to understand the rules of the 'Supernatural' world, like how angels and demons operate, and also the nature of the Wesen in 'Grimm'. Then, they can find common elements to build on. For example, both shows deal with creatures that are hidden from the normal human world. Writers can use this shared concept to create a scenario where the characters from both shows meet. Maybe a Wesen is causing trouble that has 'Supernatural' implications, so the 'Supernatural' characters get called in, and the 'Grimm' characters are already on the case.
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.
Well, in terms of the aesthetics, the dark and gloomy atmosphere of Resident Evil can be enhanced with the more neon - like, glowing elements of the Black Light. For example, infected areas could have a strange mix of the Resident Evil's dilapidated buildings and the Black Light's glowing veins running through the walls.
