A common theme that might not be as obvious at first is the theme of redemption. Kurama, having a somewhat dark past as a force of destruction, may be on a path of redemption through his relationship with Naruto. And for Naruto, he might be redeeming the reputation of tailed beasts in general. There could also be a theme of sacrifice, where either Naruto or Kurama has to sacrifice something for the sake of their relationship or for the greater good in the context of the fanfiction world.
One common theme could be the exploration of power dynamics. Given that Kurama is a powerful and ancient being and Naruto has his own growing strength, their relationship in these fanfictions might delve into how power affects their connection. Another theme could be the idea of acceptance. Naruto, being a human, and Kurama, a tailed beast, might face issues of acceptance within the story, not just of each other but also from the wider ninja world.
Well, often there can be a theme of adaptation. Naruto has to adapt to the new world of Pokemon and the presence of Pokegirls in a harem situation. There may also be a theme of protection. Naruto might feel the need to protect the Pokegirls, and in turn, they might also protect him. Additionally, the concept of growth is common. Characters grow not only in their relationships but also in their understanding of the two different universes they are part of.
Since we should avoid lemon fanfictions which are often inappropriate, let's consider regular Rhaegar and Lyanna fanfictions. A common theme is the forbidden love aspect. Their relationship was against the norms of their society, with Rhaegar being a Targaryen prince and Lyanna a Stark girl. Another theme is the impact on the political situation. Their union led to a series of events that changed the power dynamics in Westeros.
One common theme could be the exploration of the reactions of other characters. For example, how Sakura might react to such a situation. Another theme could be the impact on the ninja world as a whole. Since Naruto is a very important figure, his actions would have far - reaching consequences.
Well, aside from the 'angry' and 'lust' parts which are not always positive themes, some common themes could be power struggles. In Naruto's world, power is a big deal. So in these fanfictions, characters might be angry because of power imbalances and lust could be related to the desire for power. For example, a character might lust after a powerful jutsu and be angry when they can't obtain it.
Well, ignoring the inappropriate 'lemon' aspect, in dragon harem fanfics, cultural clashes can be a common theme. If the dragon harem consists of characters from different races or cultures, there will be clashes and also reconciliations. Also, self - discovery is often a theme. Each member of the harem may go through a journey of self - discovery as they interact with the dragon and other harem members. For example, a human in the harem might discover new magical abilities or a new understanding of their place in the world.
One common theme could be the exploration of the power dynamics between Naruto and Kurama in his fox form. Since Kurama is such a powerful entity, in these fanfictions, it might be about how Naruto manages to control or work with Kurama in a more intimate way, which could be related to the 'lemon' aspect, perhaps symbolizing a deeper, more passionate connection.
One common theme could be the exploration of friendship bonds that develop into something more during the sleepover. For example, characters might share deep secrets or have emotional conversations that lead to a change in their relationship. Another theme could be the discovery of new powers or abilities in a more intimate setting, like during a sleepover where they are more relaxed and open with each other.
Well, one common theme could be the undermining of her academic achievements. In some of these types of fanfictions, her knowledge might be belittled or misused by other characters. Another could be her social status being attacked, like her being excluded from certain groups because of her Muggle - born status, which is then used as a tool for humiliation.
There could be themes related to a Pokémon's fresh start or new beginning. For example, a Pokémon that has just hatched or been caught might be seen as 'pure' in a sense, and the fanfiction could explore its journey of discovery, much like how virginity can be associated with newness. Another theme might be about a Pokémon's untapped potential, which is similar to the idea of something being untouched or 'virginal' in a non - sexual way.
One common theme could be the reaction of the other characters in the Naruto universe. How Naruto himself might respond, or how their friends deal with the situation. Another theme could be the exploration of trust and loyalty in relationships, not just romantic ones but also friendships. Also, it might touch on the idea of redemption for Gaara if he realizes his mistake.
