The relationship between Loki and Thor is also frequently explored. In the Dark World, there's a lot of tension and history between them. Fanfictions might show them reconciling, or further straining their relationship, and how this affects the overall story of the Dark World.
Power and corruption are often explored. In a crossover, a 'dark naruto' might be tempted by the different power structures in the new world. For example, if crossing into a world like the Marvel universe, he could be faced with the allure of powerful artifacts or abilities. Another theme is identity. Naruto has to figure out who he is in a completely new setting. Is he still the same ninja from Konoha?
Willy Wonka, of course. He can be portrayed as a more morally ambiguous character. Instead of the kind - hearted, if a bit eccentric, chocolatier, he could be someone with hidden motives. Maybe his grandeur and mystery are just a facade to hide his true, less - than - noble intentions.
Character backstories are often explored. Writers like to show how the main characters were before they became part of the alien force. Another key element is the origin of the powers. They might explain how the unique abilities of the alien force came to be.
In 'Botany Bay' Star Trek fanfics, the idea of power and leadership within Khan's group is a common exploration. How Khan rules and the power dynamics among his people are interesting aspects. The survival aspect is also key. Given the situation of the Botany Bay, fanfics often show how the occupants try to survive in a new and strange universe. Additionally, the cultural clashes that might occur when they interact with other Star Trek species are often written about.
Guilt is a common theme. In 'The Tell - Tale Heart', the narrator is consumed by guilt after murdering the old man, and he imagines he can still hear the old man's heart beating. This shows how guilt can haunt a person.
Love and family are key elements. It's about Loki and Natasha coming together to form a family unit around their baby. Their love for each other and for their child is central.
One important element is the adaptation of the characters. Since it's fanfiction, the author can take liberties. Female Harry might have different traits compared to the original male Harry. And Loki, his mischievous nature is always a central part. Their combined adventures against various threats, be it dark wizards or other mythical beings, are also key. For example, in some fictions, they team up to stop an ancient curse that could destroy both their realms.
Character interaction. Since it's about cooperation, how Loki interacts with other characters, whether they are his allies or enemies turned allies, is crucial. For example, his snarky remarks and how others react to them.
Definitely Thor. Their complex relationship always adds depth to any story. You can explore their brotherly bond, rivalry, and how it changes in the context of 'The Dark World'.
One idea could be Loki having to team up with an unexpected ally from Asgard's underworld to stop a new threat that emerged during the events of 'The Dark World'.
