Meanwhile, Trevor's civilian secretary Marcia (Stella Stevens) is a double agent for the Nazi Fifth Columnists. She seeks to aid top spies in killing Trevor and opposing this new threat, Wonder Woman. Her first attempt is arranging for an accomplice to fire a machine gun at Wonder Woman during her stage act. Later, as spy activities increase, Trevor leaves the hospital but gets in a fight and is captured, prompting his "nurse" Diana to come to his rescue. Wonder Woman defeats Marcia in an extended fight sequence in the War Department. Having defeated Marcia, Wonder Woman thwarts a Nazi pilot who had plans to bomb the Brooklyn Navy Yard by using her invisible plane, and she rescues Trevor. With Marcia and the spy ring defeated, the film closes as Trevor and Brigadier General Blankenship talk about Trevor's new secretary whom Blankenship selected not only for her outstanding clerical test scores, but her decidedly plain appearance in contrast to Marcia: the bespectacled Yeoman First Class Diana Prince USNR(WR), Wonder Woman in disguise.
Wonder Woman was also allowed to become a bit more physical in the third season and could now be seen throwing the occasional punch or kick. The writers also came up with several unusual ways for Diana to execute her spinning transformation, the most notable instances occurring in the episode "Stolen Faces" in which Diana makes the change while falling off a tall building, and the season two episode "The Pied Piper" in which she changes while strapped into a spinning chair.
For a time she was given enhanced vision by Athena, which gave her the ability to see in darkness and through illusions. This also makes her resistant/immune to telepathy. Due to her wisdom she can learn languages faster than a regular person, she can talk to animals. She has also been shown to project herself astrally in order to commune with the gods and ask for special favors from them. She has also been shown to take on the abilities of certain of her patron goddesses as when she became a form of divine midwife to save the life of an unborn child.
The Gods, led by Athena, create the Amazons in Greece to realize their ideals and bring humans into following them. The leader of the Amazons, Hippolyta feels a yearning for a child). She makes a clay form of a child and prays to the Gods. Hearing this the Gods give the clay form, transforming it into a live child blessed with Gaea's gift, life. The Gods grant her various abilities and she grows up as Diana of Themyscira.
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.
