Mary Marvel was introduced as an adult instead of in her traditional teenage form, and insisted upon sharing the name of "Captain Marvel" with her brother. Captain Marvel, Jr., resenting being called "Junior" all of the time and needing a name he could say without calling down the magic lightning (his magic word being "Captain Marvel"), renamed himself "CM3". Jerry Ordway wrote all of the stories for the series and the one "Annual", and provided painted covers in the style of the graphic novel as well. Peter Krause, Mike Manley, Dick Giordano, and Ordway himself served as the series' main artists.
