In a 'tony bucky sex powered alien ship fanfic' if it were to exist, it could be a really wild and unorthodox take on the characters. It might start with Tony and Bucky in an unexpected situation that leads to this so - called 'power source' for the alien ship. The story could be filled with strange interpretations of their characters' abilities and how they interact with the alien technology. But it's important to note that this is a very odd and not - so - appropriate concept. Fanfic usually has a wide range of themes, but this would be on the far end of the spectrum of creativity and perhaps not in line with the general spirit of most fanfic communities.
If it exists, it might be a very strange and out - there story. It could involve Tony and Bucky in some sort of situation where their relationship (if misinterpreted in this way) has an impact on powering an alien ship. But this is all very speculative as it's not a typical or appropriate kind of story concept in general.
There could potentially be a 'tony bucky sex powered alien ship fanfic' out there given the wild and creative nature of fanfiction. But it's not a mainstream or well - known type of fanfic. It might be something that a very small group of fans with very specific interests have created. Also, due to the nature of the title, it might not be suitable for all audiences or all fanfic platforms, which usually have content guidelines to follow.
There could be some extremely niche or even self - created fanfics out there with all kinds of wild concepts, but I haven't come across one with this specific 'tong and bucky sex powered alien ship' idea. Fanfic communities can be very diverse in their creativity, but this seems a bit far - fetched.
One great concept could be a time - travel fanfic where characters from different historical eras interact in a fictional world. For example, a modern - day character gets transported back to the Renaissance and has to adapt to the new environment while also trying to find a way back home.
One common theme is redemption. Bucky has a complex past and Tony often has to come to terms with that. Another theme is friendship. They are two very different characters but in fanfic they often find common ground and become friends.
One great 'Bucky x Tony Tony nightmare' fanfiction is 'The Broken Alliance'. It delves deep into the complex relationship between Bucky and Tony. In this story, a nightmare situation forces them to confront their past differences and work together. The character development is really well - done, showing how they grow from being at odds to understanding each other on a deeper level.
It could be a story where Tony is made younger and Bucky takes on a parental role. Maybe it explores their relationship in this new dynamic.
Healing is another common theme. Both characters usually have their own emotional wounds. In these fanfics, through their relationship of adoption, they help each other heal. For example, Bucky's stability can help Tony deal with his insecurities, and Tony's intelligence and humor can help Bucky come to terms with his past.
The theme of friendship also runs strong. As Bucky protects Tony, they start to form a bond that goes beyond just protection. They become friends who support each other through various difficulties. Additionally, there's often the theme of sacrifice. Bucky is willing to put himself in harm's way to protect Tony, showing his selfless side.
I'm not sure specifically what 'bucky sex fanfic' is, but if it involves sexual content in fanfiction, it may not be appropriate. Fanfiction should generally adhere to ethical and moral standards, and overly sexual or inappropriate content goes against the positive nature of fan creativity.
It could be a family life full of contrasts. Bucky, who has a more somber and battle - hardened personality, and Tony, who is often flamboyant and quick - witted. But Bucky would likely encourage Tony's intelligence and creativity. They might spend time in the workshop together, with Bucky offering practical advice based on his own experiences in the field. And on family outings, Bucky would be the watchful guardian, always on the lookout for any potential threats to his son.
