One of the popular pairings is Michael/Lucifer themselves. Their complex relationship, being brothers and eternal rivals, lends itself well to shipping in fanfiction. Writers like to explore the dynamic of their love - hate relationship in a romantic or at least very intense emotional context.
Jason Todd and Sam Winchester is also a well - liked pairing. Sam's more intellectual side can complement Jason's more action - oriented nature. They could be researching together to solve a supernatural mystery. There are also some pairings with female characters from Supernatural. For example, Jason Todd and Jo Harvelle. She's a strong and independent hunter, and a relationship between them could be full of action and adventure, with both of them fighting side by side against the supernatural forces.
Some fanfictions might pair Castiel and Cisco Ramon. Castiel's otherworldly nature and Cisco's scientific mind could lead to some really interesting interactions. For example, Cisco could be fascinated by Castiel's angelic powers and try to find a scientific explanation for them, while Castiel could be intrigued by Cisco's tech - savvy ways.
Sam Winchester is quite popular to pair with Lucifer. Their connection in the show, with Sam being one of Lucifer's vessels, makes for an interesting dynamic in fanfiction. Also, Castiel. The angel's moral compass and his power contrast well with Lucifer's nature.
Well, for one, fans of Supernatural are always interested in exploring different aspects of the characters' relationships. Michael and Lucifer have a long - standing and complex history in the show. Fanfiction about them as mates allows fans to delve deeper into their connection, imagining how their personalities could interact on a more intimate level. It also gives writers a chance to play with the Supernatural lore and create new and exciting stories that might not be possible in the main show. For example, they can explore how the angelic hierarchies might react to such an unorthodox relationship.
Definitely Sam Winchester and Bruce Banner. Sam's intelligence and Bruce's scientific mind can create some really cool storylines. They can bounce ideas off each other, whether it's about hunting in the Supernatural world or scientific research in the Avengers' realm. And then there's also Crowley and Loki. They're both the trickster characters in their respective shows/movies, and when they interact in fanfics, it's usually full of mischief and schemes.
In fanfiction, many stories revolve around Lucifer's fall from grace in more detail. Writers explore what really happened and how God felt about it. There are also stories where Lucifer becomes a sort of anti - hero, fighting against other forces of evil while still being at odds with God. Some fanfictions also play with the idea of an alternate universe where God and Lucifer have a completely different relationship, like being equal partners or Lucifer being the one in control.
There's 'A Mate for the Archangels'. This fanfiction is quite detailed in its exploration of Michael and Lucifer as mates. It not only focuses on their relationship but also how it impacts the other characters in the Supernatural universe. It has a slow - burn aspect to it which makes the development of their relationship feel more natural and believable.
One interesting plotline could be their eternal struggle for power in a new, alternate universe created within the fanfiction. They might fight not just physically but also in the realm of manipulating other characters' loyalties.
Another theme is redemption. Some fanfictions depict Michael as seeking redemption through his connection with Dean. They might go on a journey together to right past wrongs, which makes for an interesting and heart - warming story arc.
One popular pairing could be Ruby and Noble 6. Ruby's innocence and determination combined with Noble 6's stoic and experienced nature can create an interesting dynamic. Their relationship could be based on mutual respect for each other's combat abilities and a shared goal of protecting the innocent.
