There's no information given to tell who the author of 'felicity is an avenger fanfiction' is. It could be an amateur writer who just wanted to explore the idea of Felicity in the Avengers' world, or it could be someone more experienced in fanfiction writing but still remains anonymous.
I'm not sure who the author is. There are so many fanfiction writers out there and without more context it's hard to determine.
It could be about a character named Felicity being inserted into the Avengers universe. Maybe she has some unique powers or relationships with the Avengers in this fan - made story.
In some fanfictions, the 7th Avenger could be a time - traveler from the future. This person has come back to prevent a major disaster that the Avengers couldn't handle without their help. They know all about the future events and use this knowledge to guide the team, but also have to be careful not to change the timeline too much.
Black Widow is often portrayed as a sort of goddess - like figure in some fanfictions. Her skills, intelligence, and mysterious past give her an air of divinity.
In some cases, it could be herself. Maybe she pushed herself too hard in her work or training, and her body or mind couldn't take it anymore. This self - inflicted harm could be a key part of the fanfiction's plot, as she then has to deal with the consequences and learn from her over - zealousness.
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.
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.
Ra's al Ghul might be another possibility. He has a long - term view of things and Felicity's intelligence could be useful for his grand plans. He might want to use her to build some sort of advanced weapon or decrypt important information.
It could be Captain America. He has a strong sense of justice and kindness. So, if he found a dog, he would surely take it under his wing and protect it. Maybe he'd even train the dog to be a mascot for the Avengers.
One possible story could be about how this Avenger, as the Princess of Asgard, uses her Asgardian powers and knowledge to help the Avengers in a battle against a powerful new enemy. For example, she might be able to call upon the Bifrost to quickly transport the team to different locations during the fight.
Diggle would be a great addition. He's Oliver's friend and partner, and his presence could add some interesting dynamics to their married life. He could offer advice or be there to help out in times of trouble.
