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 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.
Some writers create a situation where the problems in the Supernatural world are related to Hermione's world. Maybe a dark wizard has escaped into the Supernatural universe and is causing chaos. Hermione then has to team up with the Supernatural characters to stop this threat. This allows for a seamless combination of the two universes, as they both have to work towards a common goal using their respective skills and knowledge.
Writers often start with a what - if scenario. What if Naruto was born in the Mass Effect universe? How would his life be different? They use this as a starting point to blend the storylines. They also consider the political aspects of both universes. The complex politics in Mass Effect like the council races and the ninja village politics in Naruto. By making characters interact with these political systems, they merge the two universes' storylines.
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.
To blend the Ghostbusters and Avengers universes in fanfiction, a possible approach is through a shared backstory. Perhaps there was an ancient event that led to the existence of both super - heroes and ghosts. This could be a starting point for a story where the two groups discover this connection. In terms of plot, the Ghostbusters could be called in to help the Avengers deal with a ghostly manifestation of an old enemy. The Avengers, in turn, could offer their protection and resources to the Ghostbusters when they face a threat that is too powerful for their usual means. It would also be cool to see how characters like Captain America and Peter Venkman would interact, given their different leadership styles.
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 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.
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'.
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.
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.
