Photon/Captain Marvel II
Like Storm, she’s a leader. Photon/Captain Marvel led the Avengers in the comics. Her origins? She was a captain in New Orleans harbor patrol. She was exposed to extra-dimensional energy — resulting in her being able to convert her body into energy. She decides to fight crime and takes on the name — Captain Marvel. Being that the Avengers franchise is struggling with having strong superheroines and heroes of color part of the lineup, she would be a great addition to Avengers 3.
