One common theme is power dynamics. Since Loki is a powerful character, his possessiveness often plays into how he wields his power over the OC. For example, he might use his magic to keep the OC close or protect them in a way that shows his ownership.
In fanfiction, Tony being possessive of Peter can be seen as a form of over - protection. Tony, with his genius intellect and resources, might feel the need to safeguard Peter from the dangers of the world. It could also stem from a sense of mentorship and seeing Peter as a younger version of himself that he wants to guide and keep close.
In OUAT (Once Upon a Time) fanfiction, a possessive Peter Pan can add a lot of drama. He is often portrayed as a complex character. His possessiveness might stem from his eternal youth and his fear of losing what he considers 'his', like Neverland or certain characters. It can create intense relationships with other characters in the fanfic world.
At first, it could be strained. Loki might not be the best father figure right away. He may be more focused on his own goals and not fully understand how to be a dad. Peter, on the other hand, would be confused and perhaps a bit resentful.
Loki is known for his mischievous nature. In this fanfiction, he could bring out a more playful side in Peter. Peter might start to use his powers in more creative and unexpected ways, like using his web - slinging not just for fighting and swinging around, but also for creating elaborate pranks, inspired by Loki. Also, Loki's manipulative side could either make Peter more distrustful of others or teach him how to spot manipulation better, depending on how their relationship develops.
They could be forced into an alliance. Perhaps a villain has a plan that requires both Loki's magic and Peter's scientific knowledge. They start off not trusting each other at all. Loki thinks Peter is just a naive kid, and Peter thinks Loki is a troublemaker. But as they work together, they start to respect each other's abilities.
In a Loki and Peter Parker fanfiction, they could team up. Loki, with his magic and cunning, and Peter with his spider - powers. They might face a common enemy, like a powerful sorcerer who is trying to take over the city. Loki could teach Peter some new ways of using his powers, and Peter could show Loki the importance of using powers for good.
One common theme is mentorship. Loki often takes on the role of a mentor to Peter, guiding him in his powers or in understanding the more complex aspects of the universe. For example, in many stories, Loki helps Peter control his new - found abilities better. Another theme is the clash of different personalities. Loki's sly and often unpredictable nature clashes with Peter's more straightforward and good - hearted personality, creating interesting dynamics and conflicts.
Another one to check out is 'Loki's Territorial Love for the OC'. In this fanfiction, Loki's possessiveness is more on the territorial side. He sees the OC as his, and he's not afraid to show it. The story has a good plot that weaves in elements of Norse mythology along with the relationship between Loki and the OC, making it a really immersive read.
