One possible theme could be new life and growth. Just as a raven is pregnant, it could symbolize the start of something new in the story's universe. Another theme might be protection, as the characters in the fanfiction could be tasked with protecting the pregnant raven.
Well, themes could vary greatly. There could be a theme of mystery. Maybe the pregnancy of the raven is a mystery that the characters need to solve. It could also be a theme of family. The raven's pregnancy could lead to the formation of a new family unit within the story, either among other ravens or with the characters who are involved in the story for some reason.
One common theme is probably the anticipation and fear of the new life. Both Raven and Alexander may be worried about how their lives will change. Another theme could be the support system around them, like their friends and family's reactions to the pregnancy.
One common theme is the struggle with new responsibilities. Raven having to adjust to the idea of becoming a mother and all the changes that come with it, like taking care of herself while also preparing for a baby.
Well, it could be a story about how Clarke and Raven's relationship has developed in an unexpected way. Maybe there was some sort of experiment gone wrong that led to Clarke's pregnancy. Or perhaps it's a more emotional plot where their friendship turns into something more complex due to the pregnancy situation.
The plot could involve Raven and Slade being forced into an uneasy alliance due to the pregnancy. Maybe there's a prophecy that their child will have great power, and different factions either want to protect or destroy the unborn baby. Raven struggles with her emotions, as she's not sure if she can trust Slade completely, but she knows she needs his help to keep the baby safe.
In Robin Raven pregnant fanfiction, a frequent theme is the preparation for the new arrival. This can involve things like setting up a nursery, choosing names, and getting ready for the responsibilities of parenthood. Also, there may be themes related to the mystery or magic (if applicable in their fictional universe) surrounding the pregnancy.
A plot twist could be that the pregnancy is not what it seems. Maybe it's an illusion created by a villain to distract them from a bigger threat. Raven and Damian might initially believe it's real and start making all these plans, only to find out later that they've been tricked.
It could be Beast Boy. Their relationship in the original series has some chemistry, and in the fanfiction, it would be an interesting twist if he were the father. Maybe their relationship takes a new turn when Raven discovers she's pregnant.
One possible plot could be that they accidentally find themselves in a situation where Raven becomes pregnant. Peter, being the responsible type, tries to balance his superhero duties with being there for Raven. They might face challenges from both their worlds, with Peter's superhero friends being a bit skeptical and Raven's mutant comrades having their own opinions. It could be a story of them coming together against all odds to prepare for their new family member.
A rival queen from a neighboring realm could be a great addition. She might see the Raven Queen's pregnancy as an opportunity to undermine her power. This could lead to various conflicts and power plays between the two, with the Raven Queen having to defend herself and her unborn child.
Perhaps the pregnancy is a prophecy - a sign of great change. In the fanfiction, it could lead to new alliances. For example, other deities who were once her enemies might now approach her to offer protection or form an alliance. The Raven Queen would then have to decide if she can trust them, all while preparing for the new life within her.
