Well, in such a fanfiction, the story might explore how Felicity's pregnancy affects Team Arrow's dynamics. Her pregnancy could be a target for their enemies. Also, it could show her struggle to balance her role in the team with her new situation. She might start training other members more to take over some of her tasks during her pregnancy.
A Felicity pregnancy fanfic in the Arrow universe might explore how their enemies react. Some villains could see it as a weakness to exploit, while others might be unexpectedly sympathetic. It could lead to some unique story arcs, like a villain who has a change of heart after seeing Felicity's determination to protect her unborn child and decides to help Team Arrow in some way.
A fanfic could also explore the reactions of the other characters like Diggle and Thea. Diggle might offer his fatherly advice since he has experience with fatherhood. Thea could be excited about becoming an aunt and start planning all kinds of things for the baby. This would add a touch of family - like warmth to the often - intense Arrow universe.
One possible plotline could be that Felicity discovers she's pregnant just as a major new threat emerges in Star City. This creates a dilemma for her as she wants to help the team but also protect her unborn child.
First, do your research on pregnancy in general. Understand the different stages, symptoms, and how a woman's body and emotions change. This will make Felicity's character more believable in the fanfic. For example, you could write about her morning sickness and how it affects her work at Palmer Technologies.
Another idea for the plot could be that Felicity discovers something unusual about her pregnancy due to some sort of meta - human or magical influence in the Arrow - verse. This could send her and Oliver on a quest to find answers and protect their unborn child from unknown forces, all while still dealing with the regular villains and challenges in Star City.
One good example could be a fanfiction where Felicity discovers she's pregnant and Oliver has to balance his vigilante duties with being a supportive partner. They might face challenges like protecting their unborn child from their enemies in Star City.
It often makes them closer. They start to think more about their future together.
In a fanfiction, Oliver and Felicity might have a story where they start to work on a project in Star City. They spend long hours together in the Arrow cave, analyzing data and planning strategies. As they work side by side, they begin to notice little things about each other. Felicity loves how Oliver is always so focused on protecting the city, and Oliver admires Felicity's intelligence. This mutual admiration blossoms into love.
Perhaps there's a villain who targets Felicity because of her pregnancy. This villain could see the baby as a way to get back at Oliver. So, Oliver has to go to great lengths to keep Felicity hidden and safe. Meanwhile, Felicity could be using her intelligence to find a way to outwit the villain from her hiding place, all while dealing with the physical and emotional changes of pregnancy.
Sure. Fanfiction.net also has a good collection. Some stories might center around their adventures together, how they support each other during tough times in the Arrow universe. These stories are more about their connection as friends and partners rather than sexual content.
