Before she was a superhero, Carol Danvers earned the rank of colonel in the United States Air Force, where she served as a pilot, an intelligence officer and a NASA security officer. During her career she also had some adventures with an undercover alien soldier named Mar-Vell, the original Captain Marvel, who was posing as a human scientist on Earth.
During one of those adventures, her experience awakened her suite of superhuman abilities.Her mother was also an undercover Kree soldier, who had defected when, like Mar-Vell, she realized that humanity did not deserve to become yet another casualty of her homeworld’s eternal war.
Carol would use those abilities she would use to become the superhero Ms. Marvel, and later assume the mantle of Captain Marvel after Mar-Vell’s death. As Captain Marvel, Carol has a straightforward superhero powerset: She’s super strong and super durable, and she can fly and hang out in the vacuum of space without dying; you know, Superman stuff. But she can also absorb any kind of energy and release it as concentrated blasts, usually from her hands.
When Carol graduated from high school, her father refused to pay her college tuition because he believed that a woman’s place was in the home and a college degree was an unnecessary pursuit. She joined the Air Force to prove him wrong, growing estranged from her family. Her father died before they ever really reconciled — and before Carol could tell him that she was Ms. Marvel.
