Another theme is the clash of worldviews. The Leverage crew is more about earthly justice and taking down corrupt humans, while the Supernatural guys are used to dealing with otherworldly threats. So in some fanfictions, there can be interesting discussions and conflicts arising from these different outlooks. For instance, Nate from Leverage might question the Winchesters' methods of just killing demons instead of trying to reform them or something.
Team - up and friendship is also a big theme. Fans love to write about how the characters from the two shows would get along and form bonds. They might start out distrusting each other, but as the story progresses, they learn to rely on one another. Like how Hardison from Leverage might be initially intimidated by the Winchesters' tough - guy act but then realizes they are all on the same side and they become friends, sharing stories around a campfire or in a safe house.
One common theme is teamwork. Both the Avengers and the Leverage team are known for their ability to work together, and in the crossovers, it's about how they combine their different skills. Another theme is the idea of using different methods to achieve a common goal. The Avengers might use their superpowers while the Leverage team uses their con - artist skills. And of course, there's often a big bad villain that they have to defeat together.
Another option is to check out Tumblr. There are often fic recs (recommendations) posts for Supernatural Leverage crossovers. Some fics could involve the two groups coming together to take down a common enemy that has both natural and supernatural powers. For instance, a group of witches who are using their magic to manipulate a big business and cause chaos in the mortal world, and both the Supernatural characters and the Leverage team have to combine their strengths to stop them.
Another common theme is the clash of different mythologies. The show Xander is from might have its own set of supernatural rules and creatures, and when combined with the Supernatural world, there are a lot of interesting interactions. This can lead to stories where the characters have to figure out how to deal with new and unexpected threats that come from the combination of these two different mythologies.
Family and friendship is also a big theme. In 'Supernatural', the Winchester brothers' bond is central, and in 'Btvs', Buffy has her group of friends, her 'Scooby Gang'. In crossover fanfiction, these relationships are often put to the test and developed further. The characters from both shows form new friendships or rivalries, which adds depth to the story. It can be really heartwarming or full of tension depending on how the author writes it.
Family is a big theme. Both shows have strong family bonds. In 'Supernatural', it's the Winchester brothers, and in 'Charmed' it's the sisters. In the crossover fanfiction, these family units often have to work together or face challenges related to protecting their families in the new combined world.
One common theme is the clash of two different worlds. Arrow is mainly about a city full of crime and vigilantes, while Supernatural is all about the supernatural world. So, when they cross over, there's often a struggle to understand each other's ways. For example, Oliver might be skeptical of the existence of demons at first, while Sam and Dean might not be used to dealing with high - tech security systems in Star City.
Redemption is often explored. In Supernatural, many characters are on a journey of redemption, and when Lucifer is added to the mix, the idea of whether he can be redeemed or not becomes an interesting plot point. For example, some fanfictions show Lucifer being influenced by the Winchesters' sense of justice. Another common theme is the disruption of the natural order. Lucifer's presence in the Supernatural universe throws a wrench into the already complex balance of good and evil, heaven and hell, that exists in the series. This can lead to all sorts of chaos and interesting story developments.
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.
Another theme is the discovery of new powers and abilities. When the characters from the two universes meet, they might learn new things about their own powers or discover new abilities altogether. Like a Shadowhunter might learn some unique ways of banishing spirits from the Winchester brothers. This theme of self - discovery through interaction with a different world is quite prevalent.
One common theme is the clash of powers. Lucifer has his own set of demonic powers and in the Supernatural world, there are various powers like the Winchester brothers' hunting skills and the angels' powers. So, how these powers interact is often explored.
