Another theme could be the growth and development of the characters. A pregnancy in the story could be used as a catalyst for the characters to mature further. They might have to face new challenges, make difficult decisions, and learn more about themselves. This could tie in well with the existing themes of self - discovery in Persona 5.
One could be the theme of family and new beginnings. If the fanfic focuses on how the characters in Persona 5 would adapt to the idea of starting a family, it could be interesting. For example, exploring how the main character would handle the responsibilities and changes in his relationships with his friends and the world around him.
One theme could be friendship. Naruto and Tenten have friends in the Naruto universe. Their friends could play important roles in their relationship, like supporting them when they find out about the pregnancy. Another theme could be responsibility. Naruto, being a hero, would have to learn how to balance his duties with being a father - to - be. And Tenten could show her strength in handling the changes in her life.
One common theme could be the relationship dynamics. With a pregnancy involved, the way characters interact with each other, especially the pregnant character and their partner or family, often changes. There might be themes of support, worry, and anticipation.
One common theme could be relationships. How the characters' relationships change and develop during the pregnancy. Another might be self - discovery for the pregnant character. They might find new aspects of themselves as they are about to become a parent.
It could be a story where Naruto is in a world where gender roles are completely different. In this world, males can get pregnant. Naruto, being a young ninja, has to face this new reality. He has to deal with the reactions of his friends and family, and also how this affects his ninja training and dreams. It could be a story of him trying to balance his new condition with his existing goals.
Friendship could be a major theme. Yu and Chie's relationship can start as a simple friendship and then develop into something deeper as they face various challenges in the Persona 4 world together.
Another theme is the support system. It shows how the other characters in the anime, whether they are friends or family, come together to support the pregnant character. This could be through providing emotional support, like in the fanfic 'The Circle of Support' where the friends of the pregnant character make sure she never feels alone.
Another theme is the time - travel concept within the Harry Potter universe. Fans write about characters going back in time to change certain events or gain more knowledge about the past. It's an exciting way to play with the existing plot elements.
Another theme is the power of hope and resilience. Despite the horrors faced, the character finds ways to keep going and hold onto a glimmer of hope for a better future. Also, identity and self-discovery play a significant role as the protagonist navigates through difficult circumstances and tries to understand who they are in this chaos.
Perhaps it could be about Batman's influence on the city's infrastructure and culture. His presence and efforts could 'impregnate' the city with new safety measures, new community programs, and a new sense of unity. The fanfic could detail how Batman's work leads to long - term positive changes in Gotham, from better schools to improved neighborhood relations.
One theme could be the anticipation and preparation for the new life. It could show the character of Barry Potter and his/her partner getting ready for the baby, like setting up a nursery or choosing names. Another theme might be how the pregnancy affects the relationships in the story, whether it's with friends, family, or colleagues.
