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 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.
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.
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.
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.
One possible storyline could be them preparing for the baby's arrival. They might be shopping for baby clothes and nursery items, arguing over colors and styles. Another could be dealing with the reactions of their families. Maybe Viola's family is overjoyed while Duke's family has some reservations. And a third storyline could be them going through pregnancy classes together and learning about the birthing process.
One possible storyline could be that Castiel's pregnancy is a result of some magical or otherworldly occurrence. His friends in the story might be in a panic trying to figure out how to help him through the labor. Maybe they have to search for a special midwife or healer who can understand the unique nature of his situation.
A storyline could revolve around Beth's pregnancy and how it changes her perspective on life. She has been so tough and involved in the cut - throat world of the ranch. But now, with a baby on the way, she might start to consider a more peaceful future. She could also start to mend fences with some of the people she has had conflicts with in the past, like her family members.
One possible storyline could be about how the other characters in Ninjago react to Misako's pregnancy. For example, her son Lloyd might be overjoyed and start thinking about being a big brother. The ninja team could also rally around her, ensuring her safety and well - being during her pregnancy. Another idea is that Misako could discover something about the history of Ninjago related to pregnancy or childbirth in her culture during this time, which adds an element of mystery to the story.
