Another idea is that Cameron is exposed to some strange radiation or energy source that causes her to start developing what seems like a pregnancy. The humans around her are both curious and afraid. Some might see it as an opportunity to study and learn from, while others fear that it could mean the end of her as they know her or that it could bring some new danger. Cameron herself would be on a journey to figure out what is happening to her and how to reverse it if necessary.
One possible storyline could be that Cameron, being an advanced machine, discovers she has some sort of malfunction that mimics pregnancy symptoms. This could lead to her trying to understand human pregnancy in order to fix herself, while also causing confusion among the human characters she is with. They might initially think she has been reprogrammed by the enemy, but as she tries to figure it out, she begins to understand more about human emotions related to pregnancy like fear and anticipation.
Perhaps in the fanfiction, Cameron is implanted with some sort of experimental technology that behaves like a pregnancy. This technology could be a new form of weapon or a key to unlocking some great power. As she 'carries' this new development, she has to protect it from other forces that want to either destroy it or steal it for their own purposes, all while dealing with the physical and emotional changes that come with it.
One possible storyline could be that House, in his own complex way, realizes he has deep feelings for Cameron and secretly hopes she'll get pregnant as a way to tie her to him. Maybe he starts dropping hints or acting in a more protective manner around her.
One challenge could be the physical aspect. Since she is a machine, her body is not designed for pregnancy. There could be issues like her systems overheating or malfunctioning due to the extra 'load' of the pregnancy - like her power cells not being able to supply enough energy. Also, her mechanical parts might not be able to adjust to the physical changes that come with pregnancy in a human body, like the expansion of the abdomen.
Perhaps a storyline where Emerald's pregnancy is a result of some sort of experiment gone wrong. This could then lead to a race against time to find a cure or solution before the pregnancy takes a more dangerous turn, all while dealing with the internal and external conflicts in the RWBY universe.
One possible storyline could be that Zanessa discovers they are pregnant unexpectedly. They then have to deal with the reactions of their friends and family. Some might be overjoyed while others could be concerned about their future. They would need to make decisions about their careers and how to balance impending parenthood with their personal and professional lives.
One possible storyline could be about how the pregnancy affects Celestia's daily duties in her magical realm. She might have to delegate more tasks as she experiences the physical and emotional changes. Another could be the discovery of the pregnancy and how the other characters in the story react, whether it's with joy, concern, or a mix of both.
A plotline could revolve around the medical aspect if there are any complications. Since they are in a unique situation with their work in Stitchers, it could add an interesting layer. For example, if Kirsten's pregnancy somehow affects her ability to stitch, they would have to figure out how to manage that. Also, their relationship could be put to the test. The stress of a new baby might cause some arguments, but in the end, they grow stronger together.
A possible story might be that Aisha is pregnant and she decides to take a break from the Winx Club activities for a while. During this time, she could start a diary or a record of her experiences for the baby to read in the future. Her friends from the Winx Club could visit her regularly and she could be teaching them about the new magical aspects related to her pregnancy. There could also be a sub - plot where she has to deal with the expectations of her family regarding the pregnancy.
A storyline might involve Lagoona trying to balance her school life at Monster High with her pregnancy. She could be determined to keep up with her studies and participate in school activities, but find it increasingly difficult as the pregnancy progresses. There could also be a sub - plot about her relationship with her partner, and how they grow closer or face difficulties together during this time.
Well, a story could focus on Simba and Nala's journey during Nala's pregnancy. They could face challenges like finding enough food for Nala to ensure the healthy growth of the cubs. And also, they might have to deal with the anticipation and nervousness that comes with expecting new life in the pride.
One possible storyline could be that Sandor and Sansa have to face the challenges of a divided society while expecting a child. Their relationship might be under strain as they try to protect their unborn baby from the political turmoil around them.
