Another theme is the idea of Loki causing chaos in the already chaotic world of Supernatural. The Winchester brothers are used to dealing with demons, angels, and all sorts of supernatural creatures. But Loki brings a whole new level of unpredictability. For example, he might play tricks on the hunters or use his magic to mislead the supernatural entities they are hunting, which creates a lot of interesting plot twists.
A common theme is the clash of different power systems. Loki's Asgardian magic is very different from the magic and powers in the Supernatural world. So, stories often explore how these powers interact and sometimes conflict.
The theme of redemption can also be found. Sometimes Loki is written as a character who is trying to redeem himself in this new and strange world. He may start out causing trouble but then gradually find a sense of purpose in helping the Winchesters fight the greater evils. This gives a deeper layer to his character and adds an interesting character arc to the fanfiction.
Another theme is identity. Loki is a complex character with a lot of layers to his identity. In crossover fanfiction, this is often explored further. For instance, when he's in a crossover with characters from the Star Trek universe, his Asgardian identity clashes with the more scientific and logical world of Star Trek, making him question who he really is.
One common theme is Loki's struggle with her identity in a supernatural world. Since she is a complex character, fanfictions often explore how being female changes her experiences and relationships within the supernatural realm.
One common theme is redemption. Loki is often portrayed as seeking redemption for his past misdeeds while working with the Avengers. Another theme is the clash of personalities. The Avengers have very different personalities from Loki, and this often leads to interesting conflicts and resolutions. For example, Thor's relationship with Loki adds an extra layer of drama.
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.
