One common storyline could be the reactions of his friends and family. For instance, how Diggle would react to this unexpected situation, whether he would be supportive or shocked. Another could be Oliver's struggle with the physical changes and the new responsibilities that come with pregnancy.
One popular Oliver Queen pregnant fanfiction might involve a storyline where his relationship with a female character deepens in an unexpected way. For example, in some stories, it could be a result of a magical or scientific accident that leads to the pregnancy. This adds an interesting twist to his character's journey.
Fanfiction often takes creative liberties. Perhaps the writer wants to explore themes of family and fatherhood in a very different way for Oliver Queen. Instead of the typical male - led family formation, having him pregnant could be a way to delve into the emotional and physical aspects of bringing a new life into the world from a male perspective. It could also be related to a complex backstory involving some sort of scientific experiment gone wrong that gives him the ability to conceive.
Fanfiction.net is also a great place to search. Many fans post their Oliver Queen - related fanfictions there. However, the search might not be as refined as on AO3. You may need to spend some time browsing through different categories related to Arrow or Oliver Queen to find the pregnant fanfiction you're interested in.
One possible plot could be that they discover the pregnancy during a mission. They then have to keep it a secret from their enemies while also preparing for the new life. Oliver might be overprotective, and Sara could be struggling with how motherhood will change her life as a warrior.
Well, I've come across some. One interesting one had a storyline where they were pregnant in an alternate universe where the Arrowverse had some really different events. It was really creative how the author incorporated the pregnancy into the already established characters' personalities and the overall story arc of the Arrowverse. Another one focused more on the emotional journey of Sara and Oliver dealing with the pregnancy in a world full of danger and secrets.
One idea could be a story where Oliver Queen finds himself in Kara's universe by some sort of multiverse accident. He teams up with Kara to fight a common enemy that is causing chaos in both their worlds. Their different fighting styles, Oliver's more grounded archery and hand - to - hand combat and Kara's super - powered abilities, would make for an interesting dynamic in battles.
One great 'dark Oliver Queen fanfiction' is 'The Dark Archer's Legacy'. It delves deep into Oliver's darker side, exploring how his experiences on the island could have made him more morally ambiguous. Another is 'Shadows of the Hood', which shows a more ruthless Oliver in his crime - fighting activities, with a lot of complex character development.
They might face some new tensions. Felicity could be more cautious due to the pregnancy, while Oliver might still want to be as active in his vigilante work. This could lead to arguments. But at the same time, they could also grow closer as they experience this new chapter in their lives together. They would have to rely on each other more, share their fears and hopes for the future with the baby.
One common theme is empowerment. Since it's about a female taking on the role of Oliver Queen, it often focuses on how she overcomes gender - based challenges in the world of vigilantism. For example, she might face more scrutiny from male characters or society at large but still prevails.
