Writing about underage characters getting pregnant is inappropriate and goes against the spirit of the original 'Percy Jackson' series which is mainly aimed at a younger audience. So, there should not be any such fanfiction in an appropriate context.
A fanfiction could also be written about Percy and his friends starting a school for young demigods. They would have to teach the new generation about their powers, the gods, and how to survive in a world full of monsters. This would be a great way to expand on the friendship and mentorship aspects of the original series.
There shouldn't be any legitimate fanfiction with such a plot. The Percy Jackson series has a certain set of rules and moral and ethical boundaries within its fictional universe. The idea of Percy getting Hera pregnant is not only out of character but also violates the general tone and values of the series.
The 'Percy Jackson' series is aimed at a young audience, and such a plot would go against the spirit of the original works. So, it's very unlikely to find an all - ages - appropriate fanfiction with this concept. It would also be against the values of the fandom in terms of creating a positive and respectful environment.
One potential plot development could be the chaos it would cause among the gods. Artemis being pregnant would shatter her image as a virgin goddess, and there would be a lot of conflict among the deities. Another could be Percy having to face the consequences of his actions, perhaps being hunted by other gods who are angry at his 'transgression'.
One possible plot development could be exploring how Percy and his friends deal with this unexpected situation. Maybe they would have to face the reactions of the demigod community. It could also lead to Percy having to grow up very quickly and take on more responsibilities.
It's a bit of a gray area. On one hand, fanfic is about creativity and exploring different ideas. But on the other hand, this goes against the established character relationships in the Percy Jackson series. So while some might find it an interesting and different take, others may be offended or think it's inappropriate.
Most likely not. The concept of 'getting everyone pregnant' is a very adult - like and inappropriate theme in general. Fanfictions should usually adhere to certain moral and ethical standards, and this title gives the impression of something that goes against those norms.
I haven't come across a 'Luke Gets Percy Pregnant' fanfiction myself. Fanfiction writers can come up with some really wild ideas, but this one seems rather extreme. It might not be in line with the general tone or themes of the source material. That being said, the fanfiction community is full of surprises, so it could potentially exist on some less - known platforms or in some very specific corners of the larger fanfiction world.
Well, the idea of 'Percy Gets Zeus Pregnant' is quite outlandish for a fanfiction. While fanfiction allows for a great deal of creative liberty, this concept might be so unique that it may or may not have been written. Some fanfiction communities are more open to such extreme and unorthodox ideas than others. So, your best bet is to do a thorough search on popular fanfiction platforms.
