The Silver Age format for comic books also did not generally favour a lot of story arcs, or at least, not memorable ones. In this period though the character did undergo some consistent changes as she battled a variety of common foes including Kobra, but the changed format gave her the ability to develop more as a character. The silver age stories of Wonder Woman can be broken into a few general arcs – the depowered stories (in the mod girl phase), undergoing tests to re-enter the Justice League of America, a golden age story about her work during the Second World War, her adventures as an astronaut for NASA, the hunt for Kobra, and eventually the return of Steve Trevor and the internal politics of working at the Pentagon. The most famous story which she was involved with at this time was “For the Man Who Has Everything”, a story focused on Superman, but also involving herself and Batman. The first major story arc which she was part of was Crisis on Infinite Earths, which also ended her silver age appearances.
Hermes, the messenger god of speed, granted Diana superhuman speed and the ability to fly. She is capable of flying at speeds approaching half the speed of light. She can react quickly enough to deflect bullets, lasers, and other projectiles with her virtually impenetrable bracelets. After the 2011 relaunch of the character, Wonder Woman does not naturally possess the power of flight. She gains it once she is hit by a feather thrown by Hermes.[better source needed]
^ Greenberger p. 175: "Journalist and feminist Gloria Steinem...was tapped in 1970 to write the introduction to Wonder Woman, a hardcover collection of older stories. Steinem later went on to edit Ms. Magazine, with the first issue published in 1972, featuring the Amazon Princess on its cover. In both publications, the heroine's powerless condition during the 1970s was pilloried. A feminist backlash began to grow, demanding that Wonder Woman regain the powers and costume that put her on a par with the Man of Steel."
Pérez and Potter wrote Wonder Woman as a feminist character, and Pérez's research into Greek mythology provided Wonder Woman's world with depth and verisimilitude missing from her previous incarnation. The incorporation of Greek gods and sharply characterized villains added a richness to Wonder Woman's Amazon heritage and set her apart from other DC heroes.
Impressed by this unknown woman's self-sacrifice, the Amazons entombed her with honors and clothed her in armor displaying the American flag pattern on her uniform, which they assumed were her heraldic colors. Trevor's legacy was also the primary reason why Ares arranged for Steve Trevor to bomb the island, as he could not resist the irony of the heroine's son unwittingly killing her admirers.
