One common theme is the clash of different worlds. Sherlock's world of crime - solving and high - stakes mystery in London is very different from the somewhat comical and airline - focused world of Cabin Pressure. So, seeing how these two worlds interact is a big theme.
One great place to find Sherlock and Cabin Pressure crossover fanfiction is Archive of Our Own (AO3). Just search for 'Sherlock Cabin Pressure crossover' on the site and you'll be presented with a variety of fics. Some might focus on the unique character interactions, like how Sherlock's deductive skills could interact with the wacky situations in Cabin Pressure.
Character relationships are also a big theme. For example, the friendship between the captain and the rest of the crew, or the rivalries and comradery among them. Writers often delve deeper into how these relationships develop and change over time.
Sure. You can check out Archive of Our Own (AO3). There are numerous Cabin Pressure fanfictions there. Some popular ones often explore the relationships between the characters in different scenarios, like how they deal with in - flight emergencies or their off - duty interactions.
First, know both universes well. If it's a Sherlock and Harry Potter crossover, understand the rules of magic in HP and Sherlock's deductive methods. Then, create a unique plot. Maybe Sherlock is called to Hogwarts to solve a mystery that baffles the wizards. Also, keep the characters in - character. Sherlock should still be his brilliant, aloof self. And don't forget about good grammar and spelling.
One popular idea is a Sherlock crossover with the Harry Potter universe. Imagine Sherlock using his deductive skills in Hogwarts to solve magical mysteries. Another is a crossover with the Marvel universe, where Sherlock might team up with Iron Man to outwit villains using their combined intelligence. A third could be a crossover with the Doctor Who series, with Sherlock and the Doctor traveling through time and space while solving complex cases.
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.
One common theme is the clash of their personalities. Sherlock's cold logic and Hannibal's refined and sometimes sinister charm create a lot of tension. For example, in many fanfics, they initially distrust each other due to their very different approaches to life and crime - solving.
Mystery is also a big theme. Since Sherlock is known for solving mysteries, fanfiction often has him using his skills to solve some big mystery in Middle - earth, like a disappearance or a strange occurrence that's affecting the Hobbits or the whole of Middle - earth.
