One common theme is the clash of different cultures. The wizarding culture from Harry Potter and the Asgardian culture with Thor and Loki are very different. Another theme is the exploration of power. Harry's magic, Thor's strength, and Loki's trickery all represent different forms of power and how they interact.
A major theme in these fanfictions is the idea of redemption. Loki, in particular, is often given a chance at redemption through his interactions with Harry. Harry, with his kind heart and sense of justice, might influence Loki to turn away from his more devious ways. And there's also the theme of identity. Harry has to re - evaluate who he is when in a completely different world, and Thor and Loki also face questions about their own identities when confronted with the magic of the wizarding world.
One common theme is family. Their brotherly bond, whether it's strained or strong, is often explored. Another theme is redemption, especially for Loki as he has made many mistakes. Also, power and how they both deal with it, Thor with his more straightforward use and Loki with his more cunning approach, is a frequent theme.
One common theme is the clash of different power systems. The magic from Harry Potter and the divine powers of Thor often collide and combine in interesting ways.
One common theme is the clash of different magical systems. Since Loki comes from Norse mythology and Harry Potter has its own detailed magic system, seeing how these two interact is a big part of many fanfictions. For example, Loki's magic might be pitted against the spells of Hogwarts.
Another theme is the idea of power and manipulation. Loki is known for his manipulative ways in Norse mythology, and in these fanfics, he might try to use his skills to gain power within the wizarding world. For instance, he could try to influence the Ministry of Magic or even the Dark Lord Voldemort if the story takes that route. This theme also ties in with the idea of trust, as the Harry Potter characters have to figure out whether they can trust Loki or not.
A very frequent theme is the comical aspect. The contrast between Thor's seriousness and baby Loki's mischievousness leads to many humorous situations. For instance, baby Loki might steal Thor's food or use his limited magic to play tricks on Thor, like changing his hair color.
Another theme is the exploration of their deep - seated feelings for each other. Fanfictions often dig into the complex emotions that Thor and Loki have had for each other throughout their history in the original mythology and how those emotions develop into love in the context of marriage.
One common theme is redemption. Loki often has a lot to atone for, and Thor's comfort can be a step towards his redemption. For example, in many fics, Thor's acceptance of Loki despite his wrongdoings starts Loki on a path of self - improvement.
One common theme is the clash of cultures. Hermione comes from the wizarding world, while Thor and Loki are from Asgard. This often leads to interesting situations as they try to understand each other's ways.
The theme of family loyalty often shows up. Thor feels it's his duty to protect Loki because they are family. Also, the power dynamics in Asgard can be a theme. Thor's overprotectiveness can be influenced by his position of power and his need to keep Loki, who is sometimes seen as a bit of a wild card, in check.
The theme of power and responsibility also pops up. With Thor being the more responsible and power - holding one, and Loki being the more mischievous and power - hungry at times, fanfictions play around with how they balance these aspects in their relationship. For instance, there are stories where Loki has to learn to handle power from Thor in order to protect Asgard.
