Captain Marvel is a super powerful female hitter for Marvel. Her powers originate from Kree technology. She has gone by quite of few names: Binary, Warbird, Ms Marvel, and now Captain Marvel.
Under her current title (written by Kelly Sue DeConnick), Captain Marvel doesn’t use her superpowers very often (aside from flight and super strength), but is done very well overall. The series is incredibly fun to read, but somewhat understates Captain Marvel’s abilities.
