One interesting plotline could be Stiles teaming up with the Winchesters to hunt a particularly elusive and dangerous supernatural creature. Maybe it's a new type of werewolf that has powers they've never encountered before.
One interesting plotline could be Stiles initially being intimidated by the pack but then gradually forming deep friendships. For example, he might start off being scared of their supernatural powers but as he gets to know them better, he realizes they are just like him in many ways, with their own insecurities and desires.
There could also be other characters from either Stiles' world or the Winchesters' world that make appearances. For example, in Stiles' world, there might be his friends like Scott who could be mentioned or even play a small part in the story. And from the Winchesters' side, characters like Castiel could potentially show up and interact with Stiles in some really interesting ways.
Well, in some fanfictions, there might be a plotline where Stiles discovers a long - lost connection between his family and the Originals. This could lead to a whole series of events where he has to navigate his new - found knowledge and the implications it has for his relationships with his friends and family back in Beacon Hills. He could also be in a position where he has to teach the Originals about modern ways of life, which would be a really fun and comical plotline in parts.
Well, it could be that Stiles meets Dracula in a modern - day setting where Dracula has adapted to the new world in unexpected ways. He might be running a high - tech company as a front for his vampire activities. Stiles, being the curious and intelligent character he is, starts to dig deeper and realizes that Dracula is planning to use his company's technology to create a new breed of super - vampires. Stiles then has to find a way to stop him, but in the process, he also discovers that there are some good things about Dracula's plan that could benefit both humans and vampires if done right.
Another plot could involve Stiles' relationship with Peter within the pack. Since Peter can be a complex character, their dynamic might be full of tension and unexpected alliances. For example, Stiles could be the one to bring out a more protective side of Peter towards the pack members. He might also be the key to solving some internal conflicts within the pack due to his out - of - the - box thinking.
Well, a common plotline is the discovery of their mate bond. In many fanfictions, Stiles might not be aware at first that he is Peter's mate. So there could be a lot of confusion and self - discovery on Stiles' part. Peter, on the other hand, would be trying to court Stiles in his own way, which could lead to some really comical situations. Also, there could be a plotline where their relationship is challenged by the pack. The pack might not be accepting of their bond initially, thinking that Peter is too dangerous for Stiles. But through their love and determination, they prove that their bond is strong and worth fighting for.
A plotline might be that Stiles got secretly married while on a trip away from his friends. When he returns, he has to figure out how to integrate his new married life into his old friendships. There could be comical moments like trying to hide his wedding ring or coming up with excuses for why he can't hang out at certain times. Also, the relationship within the marriage could be explored. Is it a marriage of convenience that slowly turns into love? Or was it a passionate love - at - first - sight kind of marriage that they now have to deal with in secret.
Definitely Harry Potter himself. His magic and his sense of right and wrong would bring a new dynamic to the Winchester world. And then there's Dean Winchester. His tough - guy attitude and his skills as a hunter would be really cool to see interact with Harry. Sam Winchester too, with his intelligence and research skills, could be very interesting when combined with Harry's knowledge of the magical world.
One possible plotline could be Yelena initially being distrustful of the Avengers. Maybe she has been taught to view them as enemies, but as she gets to know them, she realizes they have similar goals. For example, she might find common ground with Natasha's former teammates in their fight against evil.
One interesting plotline could be Luigi and Daisy teaming up to solve a mystery in the Mushroom Kingdom. Maybe there's a strange disappearance of power - ups, and they use their unique skills to figure it out.
