The theme of adaptation is quite common. Naruto has to adapt to Alduin's world and its rules, and Alduin might have to do the same in Naruto's world. This can lead to some really funny and interesting situations. For instance, Naruto trying to use his chakra in a world where magic works differently. And Alduin trying to fly in a world full of trees and buildings. Also, the theme of power - up is there. As they face challenges together or against each other, they often gain new powers or improve their existing ones.
A prevalent theme in 'Naruto and Alduin' fanfiction is the exploration of good vs. evil. Naruto is often seen as a hero in his world, while Alduin can be portrayed as a menacing force. Their interactions can either lead to Alduin's redemption or Naruto having to defeat him to protect his world. Also, friendship or rivalry can be a theme. Sometimes they become friends despite their differences, other times they are bitter rivals. This theme adds depth to the stories and makes the relationship between the two characters more interesting. For example, in some fanfictions, Naruto tries to understand Alduin's motives and in the process, they develop a strange bond that is both friendship and rivalry at the same time.
One common theme is the exploration of power. Since Alduin is a powerful being, as a female, it often delves into how she wields that power differently. For example, in some fictions, she may use her power more maternally to protect the world rather than destroy it.
Often, there's a theme of fate or destiny. In the Skyrim lore, the Dragonborn has a certain destiny, and when a fem Alduin chases them, it can be about how that pursuit affects the Dragonborn's path. There might also be themes of attraction or repulsion. Maybe the Dragonborn has a strange allure to the fem Alduin, or vice versa, which adds an interesting layer to the story. This can lead to complex relationships being explored in the fanfiction.
A common theme is the power struggle. Since both Alduin and the Dragonborn possess great power, their relationship often involves jostling for dominance or trying to understand each other's power. Another theme is redemption. Alduin, being a somewhat villainous character, often has a story arc of redemption in these fanfictions. For example, the Dragonborn may be the catalyst for Alduin to change his ways.
One common theme could be the power dynamic. Since Alduin is a powerful character, exploring how an original character (oc) interacts with that power can be interesting. Another might be redemption, where the oc tries to change the 'female Alduin' for the better.
One common theme is faith. Since he is a bishop, many fanfics might explore his unwavering faith and how it impacts his decisions. Another theme could be leadership as he has a role in leading the religious community.
One common theme could be a different take on Alduin's power. If Alduin is female in the fanfic, the author might explore how she wields her power in a more feminine or unique way compared to the traditional male version.
One common theme could be the struggle between their different natures. Alduin is a powerful and often seen as a menacing force, while the Dragonborn has his own heroic qualities. The clash and reconciliation of these opposing characteristics can be a central theme.
The relationship between Naruto and Alduin would be an evolving one. In the beginning, Alduin may see Naruto as just another puny human who has the ability to call him. But Naruto's unique chakra and his indomitable will could pique Alduin's curiosity. As time passes, they could start to rely on each other. Naruto could rely on Alduin for brute force in battles, and Alduin could rely on Naruto for guidance in the strange new world of Naruto. There could also be moments of conflict, especially when Alduin's destructive instincts clash with Naruto's desire to protect his village and friends. But through these challenges, their relationship could become stronger and more nuanced.
I'm not sure specifically as it depends on the author's creativity. It might be a crossover where Naruto is somehow related to Alduin. Maybe it's a story that combines the Naruto universe with the lore of Alduin, perhaps exploring Naruto having special powers or a destiny related to Alduin.
Well, in these types of fanfics, a common theme is the exploration of identity. The fem Alduin may have a different identity compared to the traditional male Alduin, and the dragonborn might have to grapple with that. Another theme could be the battle between good and evil, but with a twist because of their relationship. The fanfic might explore how their relationship changes the perception of what is good and what is evil in the context of the story's world. And of course, there can be a theme of love that overcomes differences, which is quite popular in many fanfics.
