At the end of the 1960s, under the guidance of Mike Sekowsky, Wonder Woman surrendered her powers in order to remain in Man's World rather than accompany her fellow Amazons to another dimension. Wonder Woman begins using the alias Diana Prince and opens a mod boutique. She acquires a Chinese mentor named I Ching, who teaches Diana martial arts and weapons skills. Using her fighting skill instead of her powers, Diana engaged in adventures that encompassed a variety of genres, from espionage to mythology. This phase of her story was directly influenced by the British spy thriller The Avengers and Diana Rigg's portrayal of Emma Peel.
One of the things I love about event comics is that sometimes even a middling to bad event can lead to a great spin-off or post event tie in. Day of Judgement gave us J.M. DeMatteis's run on The Spectre. Infinite Crisis gave us Jeff LeMire's great run on Superboy. While not a new series, Dark Nights Metal allowed James Robinson to have the near perfect ending to Jason's story in Wonder Woman.
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.
Hermes Action Comics #267 (August 1960) Hermes is the Messenger of the Gods, and the God of Thievery, Speed, Travel, and Commerce who is based on the god of the same name. Post-Crisis, Hermes was one of Wonder Woman's earliest allies. He was eventually killed by Circe during the War of the Gods, but Wonder Woman freed him much later from Tartarus. In the New 52, the bird-like Hermes was a close ally to Wonder Woman and aided in protecting Zeke, the reincarnation of Zeus. Post-Rebirth, Hermes took the form of a tortoise and aided Wonder Woman alongside several other gods.
