By the time that Robert Kanigher took over the character, a change away from traditional comics as a whole was accomplished. He eventually veered completely away from superheroism and essentially only told stories involving the Wonder Family, which consisted of Wonder Woman, her teenage version Wonder Girl, her baby version Wonder Tot and her mother. This eventually proved not very popular and Kanigher was forced to rethink the character and cast her in a more traditional superhero context (he actually explained this decision in comics to the reader with his various creations vying to remain in continuity against his wishes). It was at this time for instance that Wonder Woman saw the return of some characters that had been missing for some time such as the Cheetah or Doctor Psycho. It was also at this time that she became a founding member of the original Justice League of America.
"Gas was intended to win the war. On that much Wonder Woman is absolutely right." said David Hambling in Popular Mechanics. Rachel Becker of The Verge stated that despite the scientific liberties of using a "hydrogen-based" chemical weapon as a plot device, the film succeeds in evoking real and horrifying history. "First off, mustard gas is such a horrible, terrifying weapon, it doesn't need to be made more potent. But if you were a chemist bent on raining destruction on the Allied forces, you wouldn't do it by replacing the sulfur atom in mustard gas with a hydrogen atom. You'd know that sulfur is the linchpin holding together this poisonous molecule."
Thus although by the modern depiction her accomplishments at the time seem ordinary, in that era they were more so. Diana Prince was originally an army nurse, but quickly attained the rank of lieutenant in Army Intelligence. This was partially a creative convenience so that she could be close to both Steve Trevor and received information which she needed to pursue her superheroics. In the real world though, this role in Army intelligence, even as the secretary to General Darnell, was still a rare position for a woman to hold in society. At this time as well, the character had her only real sidekicks in her history in the form of Etta Candy and the Holliday Girls. These characters gave the Wonder Woman a degree more of levity while also allowing the writers to focus on some issues which were more related to women. When Marston left the character, the strong driving force of the character to act as a strong moral guide and role model for female readers left as well and the character became more sensitive to the forces driving the industry as whole. Thus Wonder Woman changed somewhat to a more stereotypical woman. Her main interest was not always fighting crime, but for a time it became all in the interest of keeping Steve Trevor happy and interested in her for marriage. Also the backup stories featuring the Wonder Women of History were slowly phased out and replaced with features on marriage customs from around the world and trivial facts on random household objects.
