The Arrowverse takes inspiration from the comics, but it's not a one-to-one canon. Writers and producers make choices to create a unique and coherent TV narrative, which means not all comic details are followed precisely.
We don't really know who Felicity is without reading the story. She could be a young girl, perhaps a main character who the Christmas surprise is centered around.
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.
Felicity is likely the protagonist of the story. She could be a girl who lives in a small town. Maybe she's known for her determination and helpful nature. During the summer, she might be the one who everyone turns to when things go wrong, which is why she has the chance to save the day.
They often explore deep emotional connections between male characters. For example, they might show how two characters support each other through tough times in the Arrowverse.
No, it's not appropriate. The Arrowverse is a franchise that is aimed at a wide audience, including younger viewers. Writing sex fanfic goes against the family - friendly and heroic nature of the Arrowverse. It's better to write fanfic that focuses on positive aspects such as character development, heroic deeds, and the exploration of the complex relationships between the superheroes in a non - sexual way.
Kara Zor - El, Supergirl, is a significant character in the Arrowverse graphic novel. She has all the powers of Superman and is a powerful protector of National City. Also, Cisco Ramon, with his tech - based powers, is often a key player. He helps the heroes with his inventions and his ability to open breaches between different dimensions.
Yes, it's quite common. Many Arrowverse fans are really into the characters and the universe, and Supergirl is a popular part of it. Fanfiction offers a way to continue the adventure when the show isn't on or to explore different aspects of the character. So a lot of viewers do check out Supergirl fanfiction.
