One common trope could be the exploration of cultural differences between aliens and humans. For example, how an alien's values and social norms might clash or blend with those of a human. Another could be the power dynamics, like the 'dom' aspect might involve an alien having a dominant role over a human in certain situations, perhaps due to their superior technology or physical abilities.
Well, starting such a fanfic can be exciting. Firstly, you should brainstorm ideas for the plot. Maybe it could start with the encounter between the alien and the human. Think about how this encounter occurs, whether it's accidental or part of some grand plan. Then, you need to work on the relationship dynamics. Since it's an 'alien x human alien sub human dom' concept, you need to define how the power balance will shift throughout the story. You can also do some research on existing science - fiction concepts to get inspiration for your alien species and their technology.
It's not common at all. Fanfiction usually sticks to well - known universes and relationships. While there are some science - fiction - themed fanfics, the concept of human - robot pregnancy is rather extreme and not something that a large number of fanfic writers explore. There are other more popular themes like romance between existing characters from movies or books that get more attention.
A plot could revolve around the medical aspect. Since it's an alien - human pregnancy, there would be a lot of unknowns for the human medical field. Scientists could be trying to study the pregnancy to understand how it's possible and what implications it has for both species. Meanwhile, the pregnant human could be dealing with strange symptoms that are a combination of both human and alien pregnancy traits. This could lead to a race against time to ensure the health of the mother and the unborn child. And perhaps the couple has to deal with some sort of intergalactic bureaucracy that has rules about cross - species breeding.
When writing a 'alien x human lemon fanfic', consider the cultural differences between the two. The alien's culture might have different views on love and relationships. You can use this to create tension and drama. Outline the major plot points first, like their first encounter, the development of feelings, and any challenges they face. Then, flesh out the details with good dialogue and character actions. And always keep in mind the unique aspects of the alien - human relationship.
One idea could be an alien with unique telepathic abilities forming a deep bond with a human. The alien might be on a secret mission on Earth and the human gets accidentally involved. They start to understand each other's cultures and values, leading to a friendship that defies the differences between their species.
There could be some extremely rare and niche centaur x human pregnant lemon fanfiction out there in the vast expanse of the internet, but it's not something that is likely to be mainstream. This type of fanfiction would probably be very difficult to find, as it combines some rather unusual and potentially controversial elements. In addition, most fanfiction platforms have rules about appropriate content, and this might violate those in some way.
I'm not sure if there is such specific fanfiction readily available. Fanfiction varies widely across different platforms and communities. You would need to search on popular fanfiction websites like Archive of Our Own or FanFiction.net.
To write an 'alien and human girl fanfiction', you need to do research on different alien concepts if you want to make your alien character believable. As for the human girl, base her on real - life personalities or traits you've observed. When it comes to the story, you can have a slow - burn romance. For example, the alien and the girl start as friends and over time, feelings develop. Don't forget to add some action or adventure to keep the story interesting, like they go on a journey to find a lost alien artifact.
For the alien characters, give them unique physical traits. For example, if they live in a high - gravity planet, they could be shorter and sturdier. Also, give them distinct cultural values. For instance, their society might value group harmony over individual achievement. For human characters, base them on real - life personalities you've observed. Make their reactions to the alien realistic, like being initially scared but then curious.
