Well, it might show how Peridot deals with being cracked. She could initially be in shock and feel vulnerable. The fanfiction could explore her relationships with the other Crystal Gems. For example, Amethyst might try to cheer her up in her own unique way, while Garnet remains calm and offers practical advice on how to handle the situation.
Obviously, Peridot is one of the main characters as she's the one who gets cracked. Steven is also likely to be a main character since he often helps the other gems in difficult situations. The other Crystal Gems like Garnet, Amethyst, and Pearl might also play important roles as they would be involved in Peridot's situation, either trying to help her or dealing with the consequences of her being cracked.
Well, one aspect could be the unique relationship between Peridot and Steven in the fanfic. Peridot is such an interesting character with her growth and development throughout the series, and when paired with Steven, there can be many new storylines. Maybe it focuses on their friendship deepening into something more, or perhaps it's about them going on adventures together that are different from the main plot of the show.
In fanfics, Peridot is often depicted as highly intelligent. She brings her tech - savvy knowledge from Homeworld and uses it in various situations on Earth. For example, she might use her understanding of Gem technology to fix something that the Crystal Gems are having trouble with.
Baby Peridot in the world of Steven Universe was a curious little thing. She had just emerged and didn't quite understand all the rules. Steven found her and was instantly intrigued. He brought her home and started teaching her about Earth. They went to the Big Donut together, and Baby Peridot was amazed by all the colorful treats. Steven explained what each one was. Later, they sat on the beach, and Steven told her stories about the Crystal Gems' adventures. Baby Peridot listened intently, her eyes wide with wonder.
In some fanfictions, Peridot might get involved in time - traveling adventures. She could accidentally end up in a different era of Earth's history and have to find her way back while also dealing with the challenges of that time period. This could involve interacting with historical figures or uncovering secrets about the Gems' past that were previously unknown.
In a 'Steven Universe' fanfiction with a pregnant Peridot, one theme could be the struggle between her old self and the new self she is becoming. Her previous way of thinking and acting might be challenged by the changes brought on by pregnancy. Another theme could be the exploration of different species' biology in the 'Steven Universe' world. Since Peridot is a unique character, how her pregnancy works and what it means for her species could be an interesting theme. Also, a theme of community could be present. How the community in the 'Steven Universe' reacts to Peridot's pregnancy, whether they are accepting or have reservations, can add depth to the story. This could also tie into themes of prejudice and acceptance within the community.
Friendship is a very common theme. Steven is known for his ability to befriend others, and in fanfiction with Peridot, we often see their friendship grow and develop. They learn from each other and support one another through various situations.
A possible plot could be that Baby Peridot accidentally activates an old Gem device that causes chaos in Beach City. Steven has to work with her to fix it. Along the way, they learn more about each other and the history of the Gems on Earth.
One possible theme is growth. Both Peridot and Steven grow throughout the original series, and the fanfic could continue that growth in their relationship. They might learn to understand each other better and become stronger individuals as a result.
Fanfictions involving Jasper and Peridot often delve into their growth as characters. Jasper, who was once so focused on her own ideas of strength, can learn from Peridot's adaptability. And Peridot, who was a bit timid at first, can gain confidence from Jasper's boldness. Their relationship in fanfiction can be a mirror of how people in real life with different traits can complement each other. It's fascinating to see how different writers will develop their relationship, whether it's a friendship, a mentorship, or something more complex.
