One possibility could be that the baby is a result of some dark magic experiment. Maybe Voldemort created the baby as a new vessel for his soul, more powerful than his previous Horcruxes. The story could then revolve around the baby growing up under the influence of Voldemort's followers, who see it as the future of the Dark Lord's reign.
It could be Bellatrix Lestrange. She was one of Voldemort's most loyal followers and was quite obsessed with him. It's not hard to imagine in a fanfiction world that she might have had some sort of relationship with Voldemort that led to the birth of a baby.
One possible plot could be that the magic backfires on Voldemort during a powerful dark spell. As a baby, he has no memory of his previous self. The wizarding world is in chaos as they don't know what to do with this baby - voldemort. Some might want to kill him immediately, while others think he could be redeemed. Harry Potter, having defeated him once, feels a strange sense of responsibility and wants to make sure he doesn't grow up to be evil again.
Yes, there are likely some fanfictions out there with such a wild concept. Fanfiction often explores very strange and unique ideas, and this is definitely one of the more out - there concepts. However, it's not a part of the original 'Harry Potter' canon.
It's possible. Fanfiction communities are full of creative and often boundary - pushing ideas. While the idea of Hermione and Voldemort having a baby is extremely non - traditional given the nature of their characters in the official 'Harry Potter' story, in the realm of fanfiction, where authors like to experiment with different scenarios, such a concept could exist. Some fanfictions might explore this idea to see how it could change the whole 'Harry Potter' universe, or perhaps just for the novelty of it.
One possible plot could be that Pocahontas and John Smith reunite and start a family. They face the challenges of raising a child in a world where their two cultures collide. The baby could be a symbol of hope for the future, bridging the gap between the Native American and English settlers.
One possible plot could be about Starfire adjusting to motherhood while still being a superhero. She might struggle to balance her duties of protecting the city and taking care of her baby. For example, she could be in the middle of a fight and suddenly get a call that her baby needs her. Another aspect could be how her friends and teammates support her during this new phase of her life. Maybe they take turns babysitting or offer her advice on how to handle the baby's special powers if it has any.
In this fanfiction, the plot might be about Azula's transformation. Having a baby could be the catalyst for her to change her ways completely. She starts off as the somewhat cruel and power - hungry Azula we know, but as she takes on the role of a mother, she gradually becomes more empathetic. The baby could be a symbol of hope for her, and the story could show how she overcomes her inner demons for the sake of her child.
Maybe it could be about Lucy's journey in raising the baby, like all the challenges she faces, from sleepless nights to learning how to feed the baby properly.
Another possibility is that the fanfiction is set in a different world or time period. Astrid could be in a fantasy realm where having a baby has special significance. Maybe the birth of her baby is prophesied to bring great change to the land. So, she has to deal with the expectations of the people around her as well as her own hopes and fears for her child.
