Another theme could be their self - discovery through their interactions. Rei might start to understand her own emotions better because of Shinji, and Shinji could grow in confidence. In many fanfictions, they might also face challenges together, like dealing with the threats in their environment or the expectations placed on them by others. This can create a strong bond between them that is explored in the story.
Well, one common theme could be the power of female Arceus. It might explore how she uses her unique abilities to shape the Pokemon world. Another theme could be her relationships with other important Pokemon characters, like how she interacts with them and influences their actions.
One common theme is the exploration of their relationship. Since they are both important characters in Neon Genesis Evangelion, many fanfics delve into how they interact, understand each other, and grow closer. Another theme could be their individual growth within the context of their relationship. For example, Shinji might become more confident through his connection with Rei, and Rei might learn more about human emotions.
One common theme could be survival. The cold of winter can represent challenges, and Shinji and Rei may have to work together to survive in the harsh conditions, which reflects on their relationship.
A common theme can also be the exploration of their shared heritage. Since they are related, there might be fanfictions that focus on the family secrets or unique ninja techniques that are passed down from her father to Naruko. This not only deepens their relationship but also adds an element of mystery and intrigue to the story.
It could work by focusing on the emotional journey. Suppose Rei discovers she has some sort of new potential or ability within her that she and Shinji see as a form of 'pregnancy'. They then go through the process of coming to terms with it, sharing their fears and hopes, and building a stronger bond through this unique situation. This way, it's about the relationship and the emotional growth, not anything improper.
There could potentially be some really out - there fanfiction with that combination, but it's not something that is likely to be widely promoted or known. Fanfiction communities usually have their own standards and such a specific and potentially odd combination might not be in line with most of the content. Also, 'lemon' in fanfiction often implies adult - themed content which is not always acceptable in many platforms.
One possible theme could be their rivalry. They are known for their friendly competition in the Naruto series. Fanfiction could explore how this rivalry started, how it evolved over time, and how it made them both better shinobi.
Often, there are themes related to power dynamics. Rei may have certain powers and Jadeite his own, and how these interact within the context of their relationship can be a theme. Also, themes of redemption might be present, especially if Jadeite has done some not - so - good things in the original story. And of course, the theme of love and attraction between them is quite common in such fanfiction.
Well, family growth can be a theme. We could see Naruto's family evolving over time, learning new things together, and facing challenges as a unit. Also, the theme of family traditions, like certain ninja techniques or cultural practices that are passed down through the family generations in the Naruto world.
Friendship is also a great theme. The relationships between Harry and his teammates can be developed further. Maybe they have some inside jokes, or they help each other with schoolwork aside from Quidditch. These aspects can make for interesting fanfiction stories.
