Carol Danvers' origin story is quite complex. She was initially a U.S. Air Force pilot. She got involved with an alien Kree named Mar - Vell. An explosion of a Kree device merged her DNA with Mar - Vell's, which gave her superhuman powers like super strength, flight, and energy projection.
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.
I think their first interaction could occur at a superhero gathering. Steve would be the old - school hero, representing the values of the past, and Carol would be the new - age hero, with her more modern and out - there powers. They'd probably exchange some polite words at first, but then as they start talking about their experiences, they'd find common ground in their dedication to justice and protecting the world.
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.
One of the best Carol Danvers stories is her origin story in 'Ms. Marvel' comics. It shows her journey from a normal woman to a powerful superhero, facing challenges like gender discrimination in the military and then discovering her true powers. It's a great exploration of her character's growth.
