It should also include some unique plot twists. Maybe Carol discovers a new aspect of her powers that was not shown in the movie and this changes the course of the Endgame. Or perhaps she has a secret connection to one of the villains that no one expected. These twists keep the reader engaged.
One possibility is that she could have had more interactions with other female heroes. In the movie, Carol was a powerful addition but her interactions were somewhat limited. In a fanfic, she could have teamed up more closely with Black Widow or Scarlet Witch. This would have not only shown female camaraderie but also added more depth to the story.
No. Writing fanfic that involves sexual content about a character is inappropriate and often goes against the ethical and respectful treatment of the character and the source material. It can also be considered a form of non - consensual objectification.
In the comic universe, Carol Danvers isn't a mutant. Her powers come from a different origin and set of circumstances. It's a distinct aspect of her character development.
You could write adventure - based fanfic. For example, Carol Danvers could be on a new intergalactic mission to save a planet from a powerful enemy. This would focus on her heroism and her skills as a powerful superhero.
Another interesting one is 'Rambeau and Danvers: A Sisterhood'. It emphasizes the sister - like bond between them. The author does a great job of exploring their emotions and how they rely on each other in different situations.
In fanfictions, Carol's character can develop in response to the challenges she faces with the Avengers. For instance, if they face a powerful alien threat together, she might have to dig deep and find new aspects of her powers. This could lead to her becoming more confident and self - assured. Her character might also develop in a cultural sense. If she's from a different planet or has a different background than the other Avengers, she could teach them about her culture, and in the process, become more accepting of Earth's cultures as well. She may start to see the value in things like friendship and family that the Avengers hold dear, which could change her perspective on life.
