Wonder Woman is trained in the a variety of martial arts, making her a master of unarmed and armed combat (even proving adept with pistols). Before Flashpoint Batman considered Diana the best melee fighter on the planet, even putting her ahead of Superman, due to the combination of her power and the depth of her training. Even when depowered, she is on par with some of the best hand-to-hand combatants in the DC Universe.
In the 1910s, Peter was a staff artist at the magazine Judge, where he contributed to its suffrage page called “The Modern Woman,” which ran from 1912 to 1917. More regularly, the art on that page was drawn by another staff artist, a woman named Lou Rogers. Rogers’ suffrage and feminist cartoons very often featured an allegorical woman chained or roped, breaking her bonds. Sanger hired Rogers as art director for the Birth Control Review, a magazine she started in 1917. In 1920, in a book called Woman and the New Race, Sanger argued that woman “had chained herself to her place in society and the family through the maternal functions of her nature, and only chains thus strong could have bound her to her lot as a brood animal.” In 1923, an illustration commissioned by Rogers for the cover of Birth Control Review pictured a weakened and desperate woman, fallen to her knees and chained at the ankle to a ball that reads, “UNWANTED BABIES.” A chained woman inspired the title of Sanger’s 1928 book, Motherhood in Bondage, a compilation of some of the thousands of letters she had received from women begging her for information about birth control; she described the letters as “the confessions of enslaved mothers.”
