Definitely. You can find them on various fanfic platforms. A lot of these crossovers play with the idea of the Winchester brothers meeting Sherlock and Watson. They might team up to solve a case that involves both the natural and the supernatural, like a mystery where a series of murders seem to be caused by a supernatural entity but also have a logical, human - made aspect to them.
Some Tumblr blogs are dedicated to sharing and discussing fanfics. Search for tags like 'Sherlock Supernatural crossover fanfic' on Tumblr, and you might find links to some great stories or even some exclusive fan - made content related to this crossover.
Yes, there are many. Some might explore how Sherlock's deductive skills would handle the supernatural elements in the Supernatural universe. For example, he could try to find a logical explanation for the existence of demons or ghosts, which would create an interesting contrast with the Winchester brothers' more traditional hunting approach.
A common theme is the exploration of power. Sherlock has his mental power and deductive abilities, while the Supernatural characters have powers like magic and the ability to fight demons. In fanfiction, they might combine their powers to face a greater threat. For example, Sherlock's ability to analyze a situation could help the Winchesters in a battle against a powerful supernatural entity, and the Winchesters' knowledge of the supernatural could help Sherlock understand things he couldn't before.
When starting a Sherlock crossover fanfic, you should first identify the two franchises you're crossing. For instance, if it's Sherlock and 'The Matrix'. Consider how the concepts of the Matrix, like the simulated reality, can intersect with Sherlock's world of deduction. Maybe Sherlock discovers that the Matrix is real and has to use his detective skills to figure out who is behind it all. Plan your characters' arcs. How will Sherlock change? How will the Matrix characters view him? Once you have a clear plan, start writing the first chapter, setting the scene and introducing the main elements of the crossover.
The key elements could include maintaining the personalities and characteristics of the Sherlock and Doctor Who characters. Also, a unique and engaging plot that makes sense within the context of both shows. Maybe some time travel or a crime that defies normal logic.
The clash of different mythologies. 'Lucifer' has its own take on the devil and the afterlife, while 'Supernatural' has a vast array of demons, angels, and monsters. When these two universes collide in a fanfic, it creates a really interesting dynamic.
One great 'lucifer and supernatural crossover fanfic' is 'The Devil in the Details'. It has an exciting plot where Lucifer from 'Lucifer' gets involved in a case that the Winchester brothers from 'Supernatural' are investigating. The interactions between the characters are really well - written.
Identity is also a big theme. The undertale characters are put in new situations in the supernatural crossovers, and they start to question who they really are. For instance, if Chara is exposed to a world of angels and demons in a crossover, they might wonder if they are truly a 'bad' character or if they can change and find a new purpose in this new and complex supernatural setting.
One great 'Percy Jackson Supernatural Crossover Fanfic' is 'The Hunters and the Winchesters'. It combines the world of Greek mythology from Percy Jackson with the demon - hunting of Supernatural in a really engaging way. The characters from both universes interact in a believable manner, and the plot keeps you hooked from start to finish.
