A common theme is growth. Peter usually starts off as a bit naive and through Loki's mentorship, he grows in power and knowledge. For example, in many fics, he learns new combat moves or gains a better understanding of magic.
One great Loki Peter mentor fanfiction is 'The Guiding Hand' which shows Loki taking Peter under his wing and teaching him about magic and the multiverse in a really cool way.
One aspect of Loki and Peter's friendship in fanfiction could be their shared experiences of being outsiders in some ways. Peter, as a young superhero, might not always be fully understood by the adults around him. Loki, having his own issues with his family and the Asgardian society, can relate to that feeling. Their friendship could develop as they confide in each other about their insecurities. For example, Loki could share his tales of trying to prove himself to Odin, and Peter could talk about his struggles to balance his normal life with his superhero duties. This mutual understanding could strengthen their bond.
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.
A popular Loki and Peter Parker fanfiction is 'Unexpected Bond'. In it, Loki finds himself intrigued by Peter Parker's naivete and sense of justice. The author does a great job of building a relationship between the two characters that is both unexpected and heartwarming. You can find it on many fanfiction websites. Also, 'Partners in Mischief' is a fun read. It shows Loki and Peter getting into all sorts of adventures together, with Loki's mischievous nature often getting them into trouble, but Peter's quick thinking getting them out.
One possible scenario could be that Loki, in his mischievous ways, decides to play a prank on Peter Parker. Maybe he disguises himself as a normal citizen and lures Peter into a situation where he has to use his spider - sense and quick thinking to figure out Loki's true identity. This could lead to an interesting battle of wits between the two, with Loki's magic against Peter's acrobatic and web - slinging skills.
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.
