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.
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.
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.
One idea could be exploring the origin of Alien X's powers. Maybe there was an ancient alien race that bestowed these powers and the story could delve into that backstory.
A plot could involve a group of humans who are caught in the middle of a war between Predators and Aliens. They form an alliance with a rogue Predator who has his own reasons for wanting to stop the fighting. Maybe there's a powerful Alien queen that the Predators are desperate to kill, and the humans get dragged into that mission.
One idea could be exploring Alien X's internal conflict between Bellicus and Serena in a new situation. For example, when faced with a moral dilemma on a planet where two species are at war and both have valid reasons for their actions. Another plot could be Alien X having to deal with a powerful new enemy that can somehow disrupt his omnipotent powers. Maybe this enemy has the ability to split Bellicus and Serena's consciousness further, causing chaos within Alien X.
There are many possible plot ideas. For instance, an alien race has a very different concept of love compared to humans. A human encounters an alien from this race and they have to learn about each other's ideas of love. Maybe the alien's appearance is completely different from what humans are used to, like having multiple limbs or a different form of communication. But through patience and understanding, the two develop a deep romantic bond. Another plot could involve a time - traveling human who meets an alien in a different era and their love changes the course of history in some way.
One idea could be a young human who gets caught in the middle of an alien - predator conflict and has to use their wits to survive. Maybe they form an unexpected alliance with a lone predator who sees potential in the human. Another plot could be an alien - predator hybrid created by some mad scientist, and the two species have to team up to stop this new threat that is stronger and more unpredictable than either of them.
One idea could be that the aliens come in peace but their appearance is so strange that humans initially panic. For example, they might be made of a substance like jelly and can change their shape at will.
One idea could be that Ben has to adapt to the daily life of the alien he's stuck as. For example, if he's stuck as a Four Arms, he has to deal with constantly breaking things because of his size and strength. Another could be that he has to find a way to communicate with his friends and family in his alien form, which might be difficult if the alien has a different language or way of expressing itself.
