Often, in these types of fanfics, the theme of loyalty might be prominent. Natsu, as a werewolf, might have to deal with issues of loyalty to his friends or his werewolf pack (if there is one in the fanfic). Also, the struggle between his human and werewolf sides could be a major theme. For instance, his human side might have certain values, while his werewolf side has different instincts, and the fanfic could explore how he balances these two aspects. This can make for a very interesting character - study - like story.
One common theme could be the sense of otherness. Natsu being a werewolf sets him apart from others in the Fairy Tail world (assuming this is in the context of Fairy Tail). This otherness can lead to themes of acceptance or rejection. His friends might have different reactions to his werewolf form, and this can create a lot of drama and emotional depth in the story. Additionally, the power that comes with being a werewolf could also be a theme, and how he uses or controls that power.
Well, a major theme is the power dynamics. Werewolves usually have a hierarchical structure in these fanfics, and when combined with a romantic relationship (and the lemon elements), it creates an interesting dynamic. For example, an alpha werewolf might have a more dominant role in the relationship. Also, the theme of transformation is quite common. The process of changing from human to werewolf or vice versa can add an extra layer of complexity and sensuality to the story. Additionally, themes of protection and possessiveness are often present, as werewolves are territorial and protective of their mates.
Another common theme could be the exploration of their individual personalities within the context of their relationship. For example, how Natsu's fiery nature and Sorano's own traits interact and complement each other. It could also involve themes of loyalty and friendship, as their relationship might be built on a foundation of mutual trust and support, which then blossoms into something more romantic as the fanfic progresses.
One common theme is the rivalry - turned - into - attraction. Since Natsu and Gray are rivals in the original Fairy Tail series, in the lemon fanfics, this rivalry can often be a starting point for their relationship to develop into something more passionate.
I'm sorry, but I can't really recommend specific 'werewolf Natsu lemon fanfic' as it might involve some inappropriate or non - mainstream content. However, you can try searching on some well - known fanfic platforms like Archive of Our Own (AO3) and filter the results according to your interests.
One common theme is the forbidden love. Since werewolves are often seen as different or dangerous, the relationship between a werewolf and a human or another non - werewolf character is considered taboo in the story's context.
Power and growth is another theme. As they face challenges together, they become stronger both magically and as individuals. Their relationship also strengthens during these times. They rely on each other's powers and learn to work in harmony, which is often explored in fanfictions.
One common theme is friendship. Natsu and Happy's bond is often explored further in these fanfictions through their shared experiences with the lemon elements. Another theme is adventure. The lemon might be a catalyst for an exciting journey or quest.
