Well, a storyline could involve a magical prophecy that is misread. The prophecy might seem to indicate that there's a connection between Harry and Voldemort that is like pregnancy in the sense of creating a new form of magic or a new being. It's all symbolic and not in a sexual way. Or perhaps a magical object that binds them together and causes some sort of strange phenomenon that is similar to pregnancy in terms of how it affects their connection and the magical world around them.
A good storyline could be set in a world where magic has a mind of its own. A magical entity decides that Harry and Voldemort need to be joined in a unique way for the balance of the magical world. This joining results in a state that is like pregnancy, where there's a new entity or power growing within them. It's not about physical pregnancy but more about a magical co - existence that changes them both and has implications for the whole wizarding world. This way, it can be an interesting and non - offensive exploration of the concept.
Maybe Harry joins Voldemort because he discovers some dark secrets about the so - called good side in the wizarding world. He might think that Voldemort's way of ruling could bring a new order that is more just in his eyes. However, he soon realizes that Voldemort's true nature is far more cruel than he expected, leading to a conflict within himself.
The idea of Voldemort getting Harry pregnant goes against the original nature and themes of the Harry Potter series. J.K. Rowling's work is mainly about good vs. evil, friendship, and the fight against dark magic. So, while there might be some extremely non - canonical and out - there fanfiction on this very strange and inappropriate topic, it is not something that is in line with the spirit of the original story.
One possible storyline could be that Harry is cursed by a dark wizard. The curse has the unexpected side - effect of making him pregnant. He then has to search for a way to break the curse while dealing with the physical and emotional turmoil of pregnancy. Another could be that it's a result of some experimental magic gone wrong. He might have been trying to help someone with a fertility spell and it backfired on him.
Maybe the story could focus on Harry trying to find a way to reverse the situation. He could go on a quest to find some ancient magic or a powerful wizard who might be able to help. There could also be a plot where the Ministry of Magic gets involved, either trying to cover it up or use it as a weapon against Voldemort. And of course, there would be the internal struggle for Harry, dealing with his own feelings about Voldemort and this unexpected pregnancy.
Another storyline might involve a betrayal within the wizarding world. Suppose someone close to Harry, perhaps a fellow student who has been secretly turned to the dark side, sets a trap for Harry. Voldemort then takes advantage of this situation and kills Harry, which would have a huge impact on the entire wizarding community as they lose their hope symbol.
Another storyline might involve Harry having to hide his condition from Voldemort and his Death Eaters, as being in a vulnerable pregnant state makes him an even bigger target. He could also form unexpected alliances with female characters who help him through this difficult time.
This type of fanfiction is quite off - putting. The Harry Potter series has a well - established set of characters and relationships. Voldemort is the ultimate villain, and Harry is the hero. The idea of them in such a relationship completely breaks the boundaries of what is considered acceptable in the context of the story. Fanfiction should usually enhance or explore the existing world in a more respectful and logical way, rather than creating such shock - value scenarios.
One possible storyline could be that Sam and Jack face challenges in their military careers while also dealing with the pregnancy. Maybe there are rules against their relationship in the military context, and they have to fight to be together and also ensure a safe and happy environment for the baby. For example, they might have to keep their relationship a secret for a while.
A good storyline might be about Sawyer and Hazel finding out they're pregnant in a really unexpected way. For example, they were not planning on having a baby at all. Then, they could struggle with the decision of whether to keep the baby or not. As they think about it, they start to realize how much they actually want this new life in their future and slowly start making plans for the arrival of the little one.
One possible storyline could be Tyler and Caroline facing challenges during the pregnancy. Maybe there are issues with their families accepting it, or they have to deal with supernatural threats while protecting their unborn child. Another idea is that they discover some unique powers the baby might have which causes both excitement and fear.
