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?
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.
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.
One main theme is often the exploration of the darker side of human nature. This could include things like excessive desires, be it for power, pleasure or wealth.
One key issue could be copyright infringement. Since fanfiction is based on the existing Harry Potter universe, lawyers in the fanfiction might deal with how much creative freedom the fanfic writer has without violating the original copyright. Another could be defamation within the context of the fan - created story world. If a character is portrayed in a way that could be considered slanderous in the fictional legal framework, it might be something the lawyers handle.
One key theme is friendship. Despite their differences, Marceline and Ice King are often shown forming a bond. For example, in many fics, they start to understand each other better over time.
One key theme is redemption. Maybe the father in the fanfiction has made mistakes in the past and is now trying to make up for it through his love for his child. Another theme could be sacrifice, as fathers in Naruto often put their children's well - being above their own. For example, a father might sacrifice his own ambitions or safety for his son or daughter.
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.
