It would be extremely strange and non - traditional. It would completely distort the normal relationships and biological rules in the Harry Potter world. Maybe it would involve some dark magic or some really out - there plot devices to make such a situation possible.
I'm not sure if there is such a fanfiction. Fanfiction can cover a wide range of very creative and sometimes out - of - the - ordinary ideas, but this one seems rather unusual. You could try searching on popular fanfiction websites like Archive of Our Own or FanFiction.net to see if it exists.
I'm not aware of any such fanfiction that adheres to the original Harry Potter lore, as it goes against the established gender and biological norms of the series. Fanfiction often explores creative and sometimes out - of - the - box ideas, but this seems quite a deviation.
If there was such a fanfiction, it would surely stir up a huge debate. Some fans might be intrigued by the 'what - if' aspect, but many would be appalled. The 'Harry Potter' fandom has a strong sense of the proper portrayal of characters. Hermione's relationship with Ron or Harry is more in line with the overall feel of the series. Lucius, being a Death Eater, is not a character one would expect to have this kind of connection with Hermione. So, the reaction would be a mix of disbelief, anger, and perhaps some curiosity from a small number of people.
It's very unlikely to find an appropriate fanfiction with such a premise as it involves biologically impossible and inappropriate themes. Fanfiction should generally adhere to certain ethical and moral boundaries, and this concept goes against basic biological facts as well as the nature of the characters in the Harry Potter universe.
This is a rather strange and non - canon concept. However, in such a fanfiction, it might explore a very different magical world where male pregnancy is possible. It could involve a deep emotional bond between Sirius and Harry that goes beyond the normal bounds of their relationship in the original series. There would likely be a lot of drama and angst as they deal with the unexpected situation and the reactions of their friends and the wizarding community at large.
Well, it would completely change the relationship dynamics. There would be a huge shock factor for all the other characters. And it would also mean a major shift in the power dynamics between the two families involved.
One possible plot twist could be that the pregnancy is part of a larger scheme by a third party. Maybe Voldemort or some other dark wizard has manipulated the situation to either gain control over Lucius or to use Harry's unborn child for some dark purpose.
A 'harry gets pregnant by bill fanfic' would be a very unconventional take on the Harry Potter world. Given the fact that both Harry and Bill are male characters in the original series, for this to happen in a fanfic, it would likely involve some form of magical or otherworldly intervention. Maybe a dark magic experiment that backfires, or a strange ancient spell that has unforeseen consequences. It would also have to deal with the social and emotional implications within the wizarding world, which would be a huge departure from the normal storylines.
I'm not sure if there is such a specific fanfiction. Fanfiction can cover a wide range of very creative and sometimes controversial ideas, but this particular scenario seems rather unorthodox and not a common theme in mainstream fanfiction.
There might be some fanfiction out there with this plot, but it's not a common or widely accepted concept. The 'Harry Potter' world has a large fanfiction community with a wide variety of ideas, but this one goes against the general perception of the relationships between the characters. Hermione is a Gryffindor and has a positive relationship with the main characters, while Lucius is a Slytherin villain, so this pairing is quite unexpected and controversial.
