MARY JANE, JEAN GREY, DAREDEVIL, BLACK WIDOW all have an ongoing books that keep them going. Even most the X-women are redheads (RACHEL, HOPE, FIRESTAR, WOLFBANE). Beside,redhead/gingers most of them don't treat them very harsely compare to DC COMICS where they treat WALLY WEST into a villain/ get killed, GUY GARDNER a jerk and BARBARA GORDON into an ass.
