In February 1941, Marston submitted a draft of his first script, explaining the “under-meaning” of Wonder Woman’s Amazonian origins in ancient Greece, where men had kept women in chains, until they broke free and escaped. “The NEW WOMEN thus freed and strengthened by supporting themselves (on Paradise Island) developed enormous physical and mental power.” His comic, he said, was meant to chronicle “a great movement now under way—the growth in the power of women.”
Diana is depicted as a masterful athlete, acrobat, fighter and strategist, trained and experienced in many ancient and modern forms of armed and unarmed combat, including exclusive Amazonian martial arts. With her godlike abilities of incalculable superhuman strength, nigh-invulnerability, speed, flight, healing factor and semi-immortality, Diana’s fighting prowess is enhanced. In some versions, her mother trained her, as Wonder Girl, for a future career as Wonder Woman. From the beginning, she is portrayed as highly skilled in using her Amazon bracelets to stop bullets and in wielding her golden lasso. Batman once called her the "best melee fighter in the world". The modern version of the character is known to use lethal force when she deems it necessary. In the New 52 continuity, her superior combat skills are the result of her Amazon training, as well as receiving further training from Ares, the God of War, himself, since as early as her childhood. The Golden Age Wonder Woman also had knowledge in psychology, as did her Amazon sisters.
