Thor could develop into a more responsible and protective figure. His usual bravado might be tempered with the need to care for Valkyrie and the baby. He might become more in tune with his emotions and less impulsive in battle, as he now has a family to think about.
Valkyrie, on the other hand, might soften a bit. While still maintaining her warrior spirit, she could start to show a more nurturing side. She may also struggle with the idea of being vulnerable while pregnant, but learn to accept help from Thor and others. As the story progresses, she could become a symbol of strength in a different way, not just as a warrior but as a mother - to - be. For example, she could use her strategic skills to plan for their family's future in the midst of chaos in the realms.
One possible storyline could be that they are on a mission together when Valkyrie discovers she's pregnant. They then have to face an old enemy who wants to use the unborn child for some dark purpose. Thor is determined to protect Valkyrie and their future family at all costs.
To develop Logan's character, you could show his insecurities about becoming a father. Maybe he had a difficult relationship with his own father, and he's worried about repeating the same mistakes. For Camille, you could explore her fears of losing her independence. As the pregnancy progresses, Logan could start to become more confident in his role as a future father by taking parenting classes or reading books. Camille, on the other hand, could find a new sense of purpose in creating a loving and stable environment for the baby.
For Merlin, in the fanfic, you can develop his character by showing his inner conflict. He has a great destiny and now he's about to be a father. He might question how he can balance his duties to Camelot and his new family. Freya, on the other hand, can be developed as a strong and wise mother - to - be. She could use her knowledge of nature to ensure a healthy pregnancy. She might also be the one to encourage Merlin to not be too hard on himself and to embrace this new chapter in their lives.
In the fanfic, their relationship could be tested in many ways. Maybe there are misunderstandings about the pregnancy, like who should take more responsibility or what their future living arrangements should be. Through these challenges, they learn to communicate better. Charlie might become more assertive in expressing her needs and Harry could become more empathetic. This development in their relationship skills would be a major part of their character growth throughout the story.
Both of them could develop in terms of their relationship. The pregnancy can be a catalyst for them to communicate more openly, share their fears and hopes, and ultimately become a stronger couple. They may also develop a deeper understanding of family values as they are about to start their own family.
For Camille, you could give her a backstory that makes her pregnancy more complex. Say she has always dreamed of a big career and now she's not sure if she can achieve it with a baby. This adds depth to her character. Logan can be developed by showing his relationship with his family. If his family has strong opinions about the pregnancy, it can create internal conflict for him and show different sides of his personality.
If they kiss in fanfiction, it might make Loki jealous. Loki has always had a complex relationship with Thor, and seeing Thor getting closer to Valkyrie could stir up his envy. He might try to create some trouble between them.
Well, for Belle, the pregnancy would be a time of great change. She was already a strong - willed character, but now she has a new life to think about. She might start to teach the Beast more about the outside world, so their child can grow up with a broader perspective. The Beast would evolve from a feared figure to a loving and doting partner. He'd learn to control his temper even better because he doesn't want to stress Belle or the baby. And he'd become more involved in the castle's affairs, not just for himself but for his family.
For Kaz, his development could involve learning to trust more. He has always been a bit of a loner and mistrustful. But with a pregnant Inej, he would need to trust others to help protect her and the unborn child. This could be a huge step for him. Inej, on the other hand, might develop a more nurturing side. While she is a fighter, she would now also be a mother - to - be. She could start to see the world from a more maternal perspective, thinking about how to provide a safe and loving environment for the child.
During the pregnancy, Zuko might start to explore his softer side more. He could become more nurturing, learning how to take care of Toph and preparing for the baby. He might also become more protective, using his firebending skills to ensure their safety. Toph, on the other hand, could develop her maternal instincts early. She might use her earthbending to create a safe and comfortable environment for the baby, like building a special room or a small garden. As she goes through the physical changes of pregnancy, she also becomes more in tune with her emotions and the emotions of those around her.
